"I think that people think of snow and ice as something slippery. We think of it, amazing grip." -Andreas Mikkelsen, Norwegian rally driver during Swedish Rally 2024.
On pure glass field grip is harder than tarmac, but there was snow. This year Sweden provide Monte-Carlo tricks... now some boring regular dirt rallys to comes.
Isn't it in Scandinavia legal to drive with studs on a regular car? Don't know exactly, but I talked with a couple once, from Norway I think they were, and they told me that when you pay a little extra, it is allowed to use studs or spikes.
@@hw2508 Can't speak for the other Scandinavian countries, but in Sweden studded tyres are allowed Oct 1 - April 15 (and you have to use some kind of winter tyres Dec 1 - Mars 31). The studs are much smaller than on rally tyres though. I think that they use 7 mm long studs, while we are only allowed to use 1.2 mm long with a maximum weight of 1.1 g per stud. There's also a limit on the number of studs that are allowed to use, 90 studs for
He also lost the 1st or 2nd position in the 2023 Sweden Rally because of the tire letting go and it was from overheating and wear. Heart wrenching but this year it was won awesome 2024 season so far!
@@Disco144Kno that was because pirellis rally tyres are just awful, all the drivers hated them and called them out. After rally japan 2022 (check out sebastien ogiers comments) the drivers basically forced pirelli out the sport. Theyre now on michelins which have not just proved way more reliable theyre actually faster 😂
I live in Umeå, Sweden. And the past weekend our city hosted the Rally Sweden. It is even more impressive to see the speeds in person.. absolutely insane
I also visited the rally, but I tried to get some interesting photos. Then I met two friends who actually asked how I was doing (How are you?) Then we talked about the race, as the guys were competitors (Esapekka and Thierry). We know each other since 2010... 😉
thats right... i live not 5 km away from the german ralley and i can look not only the race although the training too... that few days i have ever free at work, because i wont miss a second of it....^^
If you haven't tried just regular studded tires on your car on ice and snow, you would be amazed! Also the guy in the video ( Esapekka Lappi) just won Rally Sweden.
Yes but beware that they absolutely destroy the roads, and cause a massive amount of fine dust pollution. It's estimated that studded tires cause 40 times greater damage to the roads than regular tires. And the studs on regular studded tires do absolute nothing in snow. They are only there for the ice.
One of apparently quite a few Finnish viewers here. We actually use studded winter tires in just day to day winter driving, although it is becoming more and more common to have studless winter tires, and even some places keeping you from using studded tires on those roads. The studded tires we use are nowhere near as agressive as the ones used on those rally cars, but still the studs are very impressive.
Swede here. I got two cars, one newer without studs and an old car with studded tires and it can handle the weather much better. But actually the slippery roads get worst when going to the south of Sweden. Not much snow but a lot of wet slippery ice. I don't know it's the same in southern Finland.
@@merhaba8 My 2014 Peugeot 208 has almost 10 yearold studded tires and theyre still okay, not the best winter tires ive had, but definitely not the worst. Not entirely sure if thats a tremendously long time for studded tires, but its had them on every winter for the past 10 years, and done very average winter conditions driving.
@@Hipas_Account So you also drive on tarseal or only snow? I’d be a bit concerned with the sidewall condition after 10yrs. We normally look at 6 years here in New Zealand but our UV is probably harder than yours and if stored inside it would be better.
The studs in these rally tires are sticking 7 mm outwards from the surface of the tire. Here in Finland, the max legal limit is 2 mm and that's for worn tires where the rubber has worn away but the stud is still there. For brand new tires, the legal limit is 1.2 mm so the studs are barely sticking out of the tire. This is the reason why studded winter tires will get better traction on ice when used a bit. And the longer studs are really important if there's some snow on top of the ice. Imagine situation where there's 5 mm worth of snow on ice. The rally tire can still grab the surface of the ice with studs, the street legal tire is fully floating on snow.
Rally Sweden 2024 was held this last weekend and only Rally Finland is faster than Rally Sweden in the WRC season. They have amazing grip, sometimes better than on gravel. The more ice the better the grip is. The grip is also off course the cars it self, they are advanced, a WRC car cost c:a 1 million USD.
I think there is a film with the old Rally Champion and Monte Carlo Winner: Timo Makinen driving a Cooper S on a gravel road in a Finnish Wood, changing gears, braking and talking while doing it! He looks like a madman but it goes incredible fast!
It's how I ended up enjoying a 1980 Buick Century Estate even in Norwegian winter, I got some narrow Pirelli studded winter tires for it, and never really had any struggles even without fancy electronics to help. My current car also has studded winter tires, but it's also more modern with traction control, so the Opel Astra diesel I got gets around easily without any wheelspin. As for the Narrower tires bit, my dad used to have a 1990 Ford Bronco, 33" summer wheels, but for winter it got some narrow M+S ones, as it was just plain better. Edit: As for legality, the rally tires aren't road legal, the studs are too big, there are road legal studded winter tires, which is what I got, though studless winter tires have gotten a lot better over the years, the one thing the studded ones still do better is driving on ice.
It is one of the biggest reasons that there are so many accidents in the winter in the US, is that they have the wrong kind of winter tires and tire sizes on their vehicles.
In Germany, stud tires were legal until the 1970s, after which they were banned because of the damage to the road surface if you changed them (often too late) to "normal" winter tires without studs. These tires often tore small pieces out of the road when there was no snow. I think the last tire sold had a 1974 label on it, everything after that was punished with a fine if you were "caught" with it... that then led to the "winter catastrophe of 1978" where army tanks were used in "civil disaster protection".
I agree with almost all of your posting, but the "winter catastrophe of 1978/79" had nothing to do tires without studs. I agree that studded tires work better on snow and ice, but only if the snow is relativly hard on the surface. I soft and even deep snow they won't work as well because they don't have anything to grip to. And back in 78/79 we had a lot of snow, and especially high snow drifts. In some places you could walk over the fields, but the roads were packed with snow up to a few meter high. That's why they brought in the army with tanks to clear the roads, and helicopter to transport provisions and people to and from those villages where the roads were drowned in the snow. I remember one morning when I wanted to go to work and when we opend the door we looked at a solid wall of snow. Went to bed again and a few hours later we took to the task of getting out f the house. Took us two hours to get a narrrow path over the 5 meter / 15 feet to the road....
@@ulie1960I would like to know which village/town/valley you are talking about. I was cross-country skiing in Austria (Tirol/Kitzbühel) a couple of winters from 1980!
@@leiflillandt1488 I live in Northern Germany near Hamburg. That winter in 1978/79 there was a certain weather situation which had cold wind from the east and there was warmer air in the west. The result were lots of snow and freezing temperatures. All of the then DDR and the northern part of Germany were under lots of snow. The wind and the type of landscape caused the problems. Snow pilled up on streets and on raillines and for a few days nothing worked. Open powerlines were damaged thus causing power outage in villages. It was a type of weather not usual for the area so nobody was prepared. They got snowplows from Bavaria to clear the roads. You can find footage on UA-cam if you look for "Schneekatastrophe 1978". There are lots of videos. Even some documentarys by the NDR our TV and radio station. One result were that one town bought a snowblower after the event and were not be able to use it for 30 years because you need a certain heigh of snow for it to work.
Google translate from a hungarian site: Driving with studded tires is allowed in Austria, the Republic of Albania, Belgium, Norway, Estonia, Finland, Denmark, Latvia, Lithuania, Luxembourg, France, Great Britain, Iceland, Ireland, Spain, Italy, Sweden and Switzerland. However, many of these countries have their own studded tire regulations. In the Scandinavian countries, for example, there is a law according to which no more than 50 studs can be on a tire per one meter of its circumference. In Austria, studded tires can only be used between October 1 and May 31 on cars under 3.5 tons, and vehicles equipped with such tires can travel at a maximum speed of 100 km/h on the highway and 80 km/h on other roads. In Belgium, angles are only allowed between November 1 and March 31, and the speed limit is stricter: 90 km/h on motorways, 60 km/h on other roads.
In France, in snow regions (like mountains), they are mandatory during winter, but are average tires with studs, not like the rally ones, For regular Rally tires (on dry tarmac or dirt), they used to have people carving then out (manually) for each stage (specific threads, very secretive). Once again , sorry for my bad English. Take care! ps, Nowadays, there's a different law, during Winter time (in snow regions), you need to have at least 'rain tyres'+ 'skirts', if not snow tyres. Studed tyres, don't do well on dry tarmac (studs come out).
Also please notice how good Esapekka's English is, as is all Nordic Rally Drivers, it is a testament to the Nordic education system. As someone growing up in roughly same part of Wales I have to say Elfyn Evans' English is very good too, lol. Pob hwyl.
So many people get that so wrong with tire width. For snow you always want narrow tires, so they can 'dig down' in the snow for grip. Deflating wide tires will also make it worse, except for the special tries they got on custom "arctic trucks. Studs are great. Driving on stud less here, but i really miss the studs frequently. Really cant beat them on (wet/warm)snow and ice. But when it gets cold stud-less works almost equally good. The colder the better. Its really great grip in -15C and below.
Rally studs are ca 5x longer than street legal studs (even those are not allowed in every country). If you might have seen somewhere winter tires with a lot of round holes then those holes can be filled with studs so you have option to get a cheaper tire that is winter legal or pay extra for better winter performance. I personally prefer factory stud placement. As for narrow vs wide tire. On normal conditions there is not much difference (i think someone even made a video about it), in rally the purpouse is to get those spikes through the snow into the frozen ground. Offroad the purpouse for big aired down tires is to float on top of the snow.
What helps "decoding" tires and how they behave is to realize that the contact patch of a tire does not move in relation to the road. It is stationary, in ideal conditions when the tire is not slipping. The the downmost point in a tire has 0kmh speed, relative to the road. If you imagine the tire to be just a lot of shoes at the end of the spokes, each shoe when it contacts the road has no speed and it is "replaced" by the next shoe. So, the contact patch doesn't move but it is replaced constantly as the tire rotates. What this means is that the friction type is static friction, which is much stronger than dynamic friction. When you move a bookshelf, it doesn't want to move, then it snaps from static friction to dynamic friction and it is fairly easily to slide around. On asphalt the difference is around 1/3rd, in favor of static friction. Rotating tire has at least one third more grip than sliding tire. In the snow and mud, things do change, on dry tarmac about 5% tire slipping is the maximum force you can get from that tire. On snow.. you are going to slide a LOT more and the difference between static and dynamic is.. a mess. But i have found it extremely useful when we are talking about tires to know how it actually works, and it is still mindblowing to me that the part of the tire contacting the road.. doesn't move, and yet, the car does... The topside of the tire moves twice as fast, so if you are going 200kmh, the top side of the tire is moving 400kmh, in relation to the road. Oh, one more thing: since the contact patch is stationary, this also means that the rubber is chemically bonding to the asphalt.. This is stickiness. The only way it can chemically bond is if it is stationary just for a moment, while being pressed against the road with a lot of force, on small area. The bonds are just hydrogen-hydrogen bonds, weak but when the tire is sticky enough.. pieces of the tire will rip off from the surface.. That is another thing that is missing when driving on snow and ice.
@@gedece it gets replaced with twice the speed of the car. The part touching the road gets replaced, too, but first it moves towards the road and then away from it (following a cycloid curve), which in this case means that its speed was momentarily zero with reference to the road.
My brother in law had a Citroen 2cv with its thin tyres, and drove up a hill in winter with no problem, where others with fat winter tyres were slip sliding away, he would put that thing in second gear and off he would go, leaving everyone behind, anyone with a tyre over 175 had problems getting traction, fortunately lately we see next to no snow, again a fantastic reaction, great fun. 😊
Yes, that was the same with my now wife. Back in the 1980s she also had a 2CV and outperformed everyone in snowy conditions. But then the tires on that car looked more like disks for an angle grinder compared to the usuall tire width on other cars. Even some motobikes had wider tires. But hey, it was fun to drive that car not only in the winter. In winter it was hard because that thing didn't have a proper heating, since the car was air cooled and had only about 0.6 liter in two cylinders (she had one of the late models with the big engine and 29 hp). Not much heat to get from that....
I also must take this point; these guys driving these WRC-cars are the best drivers on this ball. There is snow, ice, sand, stones, asphalt, light, even night and no lights but from the car, on these Narrow roads they race on. Respect.
They also face very difficult weather conditions sometimes, with fog snow heavy rain. I don’t know if you saw but on last Friday night at rally Sweden there was very difficult conditions Lappi (the guy in the video, who won the rally btw) said he couldn’t see at 50m during friday night because of the snow falling. « You have to trust the notes » he said, but damn these guys have balls of steel going this fast without even knowing where exactly they must go since they sometimes travel at 50m/s 😮 On snow ❄️ at night 🫡
The thing with the narrow tires partially refers back to the "2CV in snow and ice" video. Both the Sweden Rally and Monte-Carlo were amazing this year, the season's off to a great start.
That diagonal staggering seems unique technique that started to be used on AWD rally cars not that long ago and probably may depend on both AWD and their differentials. IIRC stems from Monte-carlo rallies that had both snow/ice and trarmac in their stages, so some teams used such different on each side tire mix of snow & tarmac tires in diagonal staggered fashion.
I believe the preference for narrow tires on Rally cars on snow/ice is due to the fact that you still drive on some kind of a road and usually you expect decent levels of snow for your tire to dig in. But if you go in Off-Road conditions on winter, you don't know what you'll meet and your chances are that if you dig in too much with the tires, you'll bank your vehicle, so you want as little pressure per surface as possible (hence, larger tires - or even tracks like in bulldozers and tanks). The same applies for snow storms, where the snow quantity falling from clouds is larger than usual. On Rally races though, the race track is still somewhat maintained and usually you don't see any high snow on it, so you'll go with what could give you the best performance (against what could allow your vehicle to get you unstuck in any situation).
narrow tires: as a student I drove an Opel Corsa and always had the last laugh when winter came "unexpectedly". With snow remaining even on the Autobahn, all the BMWs, Mercedes etc with their "breiten Schlappen"(wide slippers) as we call them, were losing their grip and "dancing" especially on the snow covered cobbled streets, whilst I was plowing thru. That was nice. And nowadays, driving a "grown up" car, I make sure to put on my winter tires in time, as I really do not want a Corsa driver laughing at me. 😂
I once bought new summer tires here in Finland and found text for all seasons North America on tire side. I was a bit surpriced cause I use studded winter tires in winter. Those on vid are only for competitions you arent allowed to use them on regular car and If I remember correct not even in Monte-Carlo rally.
Non studded snow tyres are designed to retain snow in the large grooves as snow on snow has an adhesion value better than just rubber on snow, you already understand the principle of narrow tyres on snow as that creates more pressure/weight per square cm. Fresh snow and older compacted snow present different coefficients of friction so those setting off first may consider different tyre/stud combinations from those bringing up the rear
First time on studded tyres for me was in a rental VW New Beetle just north of the polar circle. Temperature highs were between -10 and -15 Celsius, the snowy roads 100% uncleared but rather had the snow compressed to for a pretty hard surface. It was a revelation! The Beetle was going through corners like it was on rails. If I overdid it, the ESP caught the car in no time at all. Really, really nice to drive.
I was there last weekend. What an awesome event ! We rented a car with spikes to drive around and I must say we wouldn't have driven far without them. Even the main roads are covered in ice. You can drive 100kph on fast farm roads with ease. One of the best driving experience of my life. The rally was cool too lol
In drifting, narrow front wheels are also good chose because when you're flying with turned wheels, the front wheels grip the road better, increasing control and helping to brake when going backward. For example, take an eraser and try running it along the surface with the front and side faces. The side will bend, but it grips the surface better.
Even on dry surface, the best tyre width is defined by the weight of the car. You basically want the narrowest tires that are strong enough not to shear away with the forces caused by the weight of the car during cornering and braking.
Supposedly american cars were actually bad for "advanced driving". Everything that is not going straight. They don't have cars that can do this, so they don't have skill and so they like everything that does not involve steering wheel, just power :) But drag race engeneering is super insane! And u can see the whole track from one place, no chance in rally thru few villages.
Ian it's like everything in America is just of a lower standard. The build standards and safety features of American cars are so substandard compared to Europe and the world of the world. When you look at how many German , Japanese and British luxury cars like Aston Martin, Bentley and Rolls Royce are exported to America. However no American cars are exported to the rest of the world. Solely made for the US market only because they wouldn't pass the European safety standards.
in german winters we had almost no problem with the CV2 :) Several vids out here on youtube. Random video on the search term "CV2 winter" is "How good is a Citroen 2CV in the snow?" in it's title.
In Sweden the old regulations state that a studded tire may have a maximum of 50 studs per meter of rolling circumference with a maximum stud protrusion of 1.2 millimeters when new. There is a new supplementary set of regulations that measures road wear. Then each tire model is tested and then the number of studs in the test and protrusion when the tire is new is indicated. There is no maximum number of studs.
You should watch a video titled "The Fastest Tractor (Full length) New Guinness World Record, Juha Kankkunen & Nokian Heavy Tires" showing a tractor running 130 km/h after snow on winter tires .Winter tires are narrower to increase the pressure on the ground, which translates into better grip. Wide tires are used for driving on sand and mud to reduce the pressure on the ground and increase the grip surface
Up here in Wisconsin we had studded tires on a car when I was a kid in the 70s. Wisconsin has banned them now tho because they tear up the roads too much. Chains are still legal tho, I'm pretty sure.
In the U.S., different states have different laws regarding studded tires, what kind of studs, and when you can use them. Some states do not allow any kind of studded tires. A big mix. 📻🙂
@IWrocker You were wondering is studded tires were street legal. That raised my curiosity as well. I live in southern Ontario, and they aren't legal here, but they've been legal in norther Ontario for as long as I can remember. I looked it up, and it turns out they are legal in all provinces with some allowing them earlier in the season, and going until either March, April or May depending on where you are. Now something interesting. Those rally tires had up to 280 studs per tire, but in the jurisdictions that allow them here, it seems you are only allowed 130 studs total for all 4 wheels. Interesting!
"When we talk of car driving, we're talking Rally car driving. Everything else is a walk in the park." Walter Röhrl, 2x Rally Champion, 14 Rally wins and Group-B-Monster, giving Audi Quattro the prestige it has now. Still drives in show races with older cars at age 76.
The tires on the right can look like this after only approx. 30-50 km of driving, if there is some gravel in the grooves. Rally tires may not be used on public roads, except in designated competitions.
6:44... You said "the used one after a long time"... That tire can look like that after one stage if there is much gravel peaking through the ice. They have to keep after the tires all the time to save them. A WRC tire isn't legal to drive if your not in competition in Sweden. To many studs and to high studs to be legal on the road. Other countrys, no idea!!
I can't imagine anywhere allowing such agressive studs, would absolutely tear up the asphalt, it would be like driving with snow chains for half the year. Maybe somewhere with only dirt roads.
I'm not American but I love NASCAR, however Rally is on a totally different level of craziness. How people don't constantly die in rally (both drivers/co-drivers and ESPECIALLY spectators) I don't know.
Have you seen the inside of a rallycar? They are way safer than a normal street car and it's way more dangerous to drive in normal traffic than in a rally competition. :)
@@Arjay404 Spectators are in alot more danger, yeah. That is one of the biggest issues with rallying today. Some people don't understand the danger they put themselves in, and the sport if a big accident would happen. In the WRC today, there are safety officials that study live incar videos and if they spot spectators in dagerous places, the stage will be cancelled immediately.
You can’t buy rally1 spec car tires,but you can buy ”lower class” tires. 1 pirelli costs something like 500euros,so it’s like 5000-8000€/race in amateur class race just for tires.
At first, I was too distracted by the man's lack of any legs to hear what he was saying about the tires! 🤣🤣 Luckily, he moved his foot a minute and a half in - I thought they were the chair legs from the start! 😅
Narrow tires make a really big difference in the snow. Even with no studs humble VW beetle and Citroen 2CV work much better in the snow than most much fancier cars. Weight of the engine over the driving wheels makes a difference too.
You know Asfalt racing, as we call it here in Norway. there they use both rain tires and slicks, but they also use to change the camber and throw angles, this to improve the grip on the tarmac. This is not done in Rally, where the damper path is just as important, whether it is a summer rally or a winter rally. The car is often much stiffer on summer rallies than on winter rallies, even though the damper travel may be the same length. I have even tried a rally car on ice with studs, and it fits almost better than normal tires on summer roads.
When there is enough snow the Sweden rally has the highest cornering speeds because the drivers use the walls of snow either side of the road to keep the rear of the car in line.
studs are forbidden on public road in many european countries. The countries I know that studs are used on public roads in the winter season, are Sweden, Finland and Switzerland. In Switzerland the cars with studs have to have a sticker in back of the car, showing that the speed limit is 80 km/h. Most roads in Sweden and Finland are always covered in snow. In Switzerland, snow on the roads in the mountains and mountain valleys are cleared there is still a layer of snow. With the right equipment its saver to drive on snow than on salted roads where melted snow could turn to black-ice. You go to Denmark (and I have seen it alot in the US as well), and just a little snowfall on the road is enough to create chaos on the road, by cars that do not have winter tires (not all season). In the US, it was mainy trucks that were laying left and right, simply because of gravitationsl balance being too high above the road and because of rear wheel drive, where the truck is the lightest - a recepy for disaster. In Switzerland and Germany (and other countries) you loose your drivers license if caught driving without winter tires during winter season. If you are involved in an accident, no insurance will pay for the damage as well, if no winter tires during winter season. Could be an interesting subject for you to cover ;) Greetings!
Suggestion - please watch a Video about 'Fiaker' in Vienna, Fiaker is a horse drawn carriage who rides in the streets of Vienna in the first district.

The inflation problem with heat can be solved by filling the tires with nitrogen gas. It's inert and won't be as affected by heat as air, less expansion. That's why airplane tires are filled with nitrogen. And narrow tires are better in the wet to, with less risk for aquaplaning. The narrow tire have it easier pushing the water to the sides since it have shorter way to push the water out to the sides as long as you have a good thread. And rally tires aren't street legal since they'd rip up the road surface.
The more weight that you put on ice will help ice to change it from a solid state to a liquid state. The smaller the surface area of the weight, the more pressure you exert on the ice to change it to a liquid. That's why ice skate blades look the way they do.
His tires has 288 studs. In comparison, here in Norway tires larger than 16" are allowed 130 studs and those studs are also WAY smaller than on the rally tires. No wonder theres a notable difference around a track :o
I lived in Finland for 10 years and they have a law that says you have to have winter tires on your car from 01.11 to 31.03> they have two kinds of tires ones with studs in (NOT as big as the studs rally cars use) for mostly Icy roads and snow tires, these do not have studs but are better at gipping to just snow and they make a really big different
Isnt there maximum average speed limit on rally stages, like 150 kilometers or more before that stage gets ruled out because of safety? And a limit of how many tires allowed per car as Esapekka Lappi mentions tyre rotation, as otherwise the put new ones on for every stage?
When you look at the tires that are used on rally cars in winter rallies, there's no need to be surprised. They have such spikes that it's a wonder if they don't bite into ice or harder snow
In FInland those used rally tires are abundent. every village where there is icetrack in winter, there is atleast one who has those. no roadlegal tho, just icetrack and racing use. you can pick up dryrotted rallyspike tires for like 50-100e a round. there is no use for those in real racing anymore so they are problem waste to them but a nice score for icetrack drivers.
In the Nordic countries studded tyres are legal on street cars while in central europe like germany and austria they are not. So it's pretty scary transversing the alps on summer tyres. I use not studded winter tyres in Stockholm because they have a softer rubber mixture than summer tyres which gives me a good grip on winter surfaces, except on polished ice, and doesn't wear down the tarmac on snow-free roads. But my winter tyres are slimmer than the ones I use in the summer.
you should check out some Hard Water Racing. both cars and bikes. (HWR) is racing on a frozen lake or body of water. theres different classes - rubber to ice, stud to ice rear or front wheel, and and 4 stud to ice... huge difference no stud and studded in times. the same can be said for bike racing on ice too. for cars and bikes here it mostly circle track racing. hard to make a road track with equipment on the ice and not fall through as everything depends on ice thickness. also the stress put down on the ice to so you prefer to build it in shallow water like a bay. we keep the cars to 4cyl and the weight down and both the car clubs and the bike clubs work hand in hand to due a full weekend of racing. ave temps here on a nice day is -20C or -30c but if there is a wind then its much worse, lol
Should come check out Rally Estonia / Rally Finland in person and taste some of the awesome local beers and be part of the whole rally crowd for once in a lifetime experience. With Norwegian Air, plane tickets from Chicago/NY to Norway/Finland/Latvia used to be like 200$.
Beer? In Finland? Do they still have these type classes from I to IV? We always called it "children's amusement water" and smuggled pallets of German beer into Finland 🤣
Actually they tested street tires and it didn‘t make a big difference if they used narrow or wider tires. The Problem is the compound. It makes the difference, also it depends on what kind of snow. But never try a summer or all season tire in real snow. Cheers from Switzerland
Look at how thin tires are in truck and tractor pulls, when going through mud. They are thinner. Even the tires that look wider, once they start spinning, will become thinner.
I love mountain biking on snow and ice (Switzerland) when most people leave their bicycle in the basement. It's not 200 km/h but nevertheless slippery :-)

@@maybenot6075serious.. maybenot....definitely troll, or one of our lovely bots.
I live in Umeå, Sweden. And the past weekend our city hosted the Rally Sweden. It is even more impressive to see the speeds in person.. absolutely insane
I also visited the rally, but I tried to get some interesting photos.
Then I met two friends who actually asked how I was doing (How are you?) Then we talked about the race, as the guys were competitors (Esapekka and Thierry). We know each other since 2010... 😉
thats right... i live not 5 km away from the german ralley and i can look not only the race although the training too... that few days i have ever free at work, because i wont miss a second of it....^^
If you haven't tried just regular studded tires on your car on ice and snow, you would be amazed! Also the guy in the video ( Esapekka Lappi) just won Rally Sweden.
finns = na.i's
Yes but beware that they absolutely destroy the roads, and cause a massive amount of fine dust pollution. It's estimated that studded tires cause 40 times greater damage to the roads than regular tires. And the studs on regular studded tires do absolute nothing in snow. They are only there for the ice.
@@Mastermind12358 Yeah. Studded tires are the norm here and I use them too. More than half of the year is ice and snow.
@@Mastermind12358 good lord. go back to the cave u came from
@@Mastermind12358 1cm studs here. fk the government and their shitty pavement
One of apparently quite a few Finnish viewers here. We actually use studded winter tires in just day to day winter driving, although it is becoming more and more common to have studless winter tires, and even some places keeping you from using studded tires on those roads. The studded tires we use are nowhere near as agressive as the ones used on those rally cars, but still the studs are very impressive.
Swede here. I got two cars, one newer without studs and an old car with studded tires and it can handle the weather much better. But actually the slippery roads get worst when going to the south of Sweden. Not much snow but a lot of wet slippery ice. I don't know it's the same in southern Finland.
Can you drive studded tyres on sealed roads at all without quickly wearing them out?
@@merhaba8 yes the studs barely peak out at all on street legal tires. But those rally tires would wear out in no time.
@@merhaba8 My 2014 Peugeot 208 has almost 10 yearold studded tires and theyre still okay, not the best winter tires ive had, but definitely not the worst. Not entirely sure if thats a tremendously long time for studded tires, but its had them on every winter for the past 10 years, and done very average winter conditions driving.
@@Hipas_Account So you also drive on tarseal or only snow?
I’d be a bit concerned with the sidewall condition after 10yrs. We normally look at 6 years here in New Zealand but our UV is probably harder than yours and if stored inside it would be better.
The studs in these rally tires are sticking 7 mm outwards from the surface of the tire. Here in Finland, the max legal limit is 2 mm and that's for worn tires where the rubber has worn away but the stud is still there. For brand new tires, the legal limit is 1.2 mm so the studs are barely sticking out of the tire. This is the reason why studded winter tires will get better traction on ice when used a bit.
And the longer studs are really important if there's some snow on top of the ice. Imagine situation where there's 5 mm worth of snow on ice. The rally tire can still grab the surface of the ice with studs, the street legal tire is fully floating on snow.
This dude is Esa-Pekka Lappi from Finland, who also won the last Swedish WRC-rally just some days ago. Greets from Finland 🇫🇮
Rally Sweden 2024 was held this last weekend and only Rally Finland is faster than Rally Sweden in the WRC season. They have amazing grip, sometimes better than on gravel. The more ice the better the grip is. The grip is also off course the cars it self, they are advanced, a WRC car cost c:a 1 million USD.
Love my Nokian Hakka 8 studded tires. But then again I live in Northern Norway where we have snow and ice from Oct to late Apr.
Lappi won the Sweden Rally yesterday.
I think there is a film with the old Rally Champion and Monte Carlo Winner: Timo Makinen driving a Cooper S on a gravel road in a Finnish Wood, changing gears, braking and talking while doing it! He looks like a madman but it goes incredible fast!
It's how I ended up enjoying a 1980 Buick Century Estate even in Norwegian winter, I got some narrow Pirelli studded winter tires for it, and never really had any struggles even without fancy electronics to help.
My current car also has studded winter tires, but it's also more modern with traction control, so the Opel Astra diesel I got gets around easily without any wheelspin.
As for the Narrower tires bit, my dad used to have a 1990 Ford Bronco, 33" summer wheels, but for winter it got some narrow M+S ones, as it was just plain better.
Edit:
As for legality, the rally tires aren't road legal, the studs are too big, there are road legal studded winter tires, which is what I got, though studless winter tires have gotten a lot better over the years, the one thing the studded ones still do better is driving on ice.
I've heard rally drivers state that there's more grip with the studded tyres on snow and ice than there is with normal dirt tyres on a dirt course.
Rally winter tires got absolute brutal grip last year at WRC Swedish Rally the highest avrage´s speed over the even was 141 km/t (87,6 mph).
It is one of the biggest reasons that there are so many accidents in the winter in the US, is that they have the wrong kind of winter tires and tire sizes on their vehicles.
In Germany, stud tires were legal until the 1970s, after which they were banned because of the damage to the road surface if you changed them (often too late) to "normal" winter tires without studs. These tires often tore small pieces out of the road when there was no snow. I think the last tire sold had a 1974 label on it, everything after that was punished with a fine if you were "caught" with it... that then led to the "winter catastrophe of 1978" where army tanks were used in "civil disaster protection".
I agree with almost all of your posting, but the "winter catastrophe of 1978/79" had nothing to do tires without studs. I agree that studded tires work better on snow and ice, but only if the snow is relativly hard on the surface. I soft and even deep snow they won't work as well because they don't have anything to grip to. And back in 78/79 we had a lot of snow, and especially high snow drifts. In some places you could walk over the fields, but the roads were packed with snow up to a few meter high. That's why they brought in the army with tanks to clear the roads, and helicopter to transport provisions and people to and from those villages where the roads were drowned in the snow. I remember one morning when I wanted to go to work and when we opend the door we looked at a solid wall of snow. Went to bed again and a few hours later we took to the task of getting out f the house. Took us two hours to get a narrrow path over the 5 meter / 15 feet to the road....
@@ulie1960I would like to know which village/town/valley you are talking about. I was cross-country skiing in Austria (Tirol/Kitzbühel) a couple of winters from 1980!
@@leiflillandt1488 I live in Northern Germany near Hamburg. That winter in 1978/79 there was a certain weather situation which had cold wind from the east and there was warmer air in the west. The result were lots of snow and freezing temperatures. All of the then DDR and the northern part of Germany were under lots of snow. The wind and the type of landscape caused the problems. Snow pilled up on streets and on raillines and for a few days nothing worked. Open powerlines were damaged thus causing power outage in villages. It was a type of weather not usual for the area so nobody was prepared. They got snowplows from Bavaria to clear the roads. You can find footage on UA-cam if you look for "Schneekatastrophe 1978". There are lots of videos. Even some documentarys by the NDR our TV and radio station. One result were that one town bought a snowblower after the event and were not be able to use it for 30 years because you need a certain heigh of snow for it to work.
Google translate from a hungarian site:
Driving with studded tires is allowed in Austria, the Republic of Albania, Belgium, Norway, Estonia, Finland, Denmark, Latvia, Lithuania, Luxembourg, France, Great Britain, Iceland, Ireland, Spain, Italy, Sweden and Switzerland. However, many of these countries have their own studded tire regulations. In the Scandinavian countries, for example, there is a law according to which no more than 50 studs can be on a tire per one meter of its circumference. In Austria, studded tires can only be used between October 1 and May 31 on cars under 3.5 tons, and vehicles equipped with such tires can travel at a maximum speed of 100 km/h on the highway and 80 km/h on other roads. In Belgium, angles are only allowed between November 1 and March 31, and the speed limit is stricter: 90 km/h on motorways, 60 km/h on other roads.
Yeah, but the studs are also very different and much smaller, studded rally tires are not road legal in any amount because of their big size.
In France, in snow regions (like mountains), they are mandatory during winter, but are average tires with studs, not like the rally ones, For regular Rally tires (on dry tarmac or dirt), they used to have people carving then out (manually) for each stage (specific threads, very secretive).
Once again , sorry for my bad English. Take care!
ps, Nowadays, there's a different law, during Winter time (in snow regions), you need to have at least 'rain tyres'+ 'skirts', if not snow tyres.
Studed tyres, don't do well on dry tarmac (studs come out).
Also please notice how good Esapekka's English is, as is all Nordic Rally Drivers, it is a testament to the Nordic education system. As someone growing up in roughly same part of Wales I have to say Elfyn Evans' English is very good too, lol. Pob hwyl.
From this weekend rally sweden.
And the Guy in the clip was the winner of the rally.
So many people get that so wrong with tire width. For snow you always want narrow tires, so they can 'dig down' in the snow for grip. Deflating wide tires will also make it worse, except for the special tries they got on custom "arctic trucks.
Studs are great. Driving on stud less here, but i really miss the studs frequently. Really cant beat them on (wet/warm)snow and ice. But when it gets cold stud-less works almost equally good. The colder the better. Its really great grip in -15C and below.
Next WRC rally is in Kenia Safary Rally ! There is totally differend tyres.
Rally studs are ca 5x longer than street legal studs (even those are not allowed in every country). If you might have seen somewhere winter tires with a lot of round holes then those holes can be filled with studs so you have option to get a cheaper tire that is winter legal or pay extra for better winter performance. I personally prefer factory stud placement. As for narrow vs wide tire. On normal conditions there is not much difference (i think someone even made a video about it), in rally the purpouse is to get those spikes through the snow into the frozen ground. Offroad the purpouse for big aired down tires is to float on top of the snow.
IWRocker You should visit WRC Rally in my hometown Umeå in Sweden next year in the middle of februari and see some cool winter rally!
I was there ! Awesome region I will come back next year for sure !
What helps "decoding" tires and how they behave is to realize that the contact patch of a tire does not move in relation to the road. It is stationary, in ideal conditions when the tire is not slipping. The the downmost point in a tire has 0kmh speed, relative to the road. If you imagine the tire to be just a lot of shoes at the end of the spokes, each shoe when it contacts the road has no speed and it is "replaced" by the next shoe. So, the contact patch doesn't move but it is replaced constantly as the tire rotates.
What this means is that the friction type is static friction, which is much stronger than dynamic friction. When you move a bookshelf, it doesn't want to move, then it snaps from static friction to dynamic friction and it is fairly easily to slide around. On asphalt the difference is around 1/3rd, in favor of static friction. Rotating tire has at least one third more grip than sliding tire.
In the snow and mud, things do change, on dry tarmac about 5% tire slipping is the maximum force you can get from that tire. On snow.. you are going to slide a LOT more and the difference between static and dynamic is.. a mess. But i have found it extremely useful when we are talking about tires to know how it actually works, and it is still mindblowing to me that the part of the tire contacting the road.. doesn't move, and yet, the car does... The topside of the tire moves twice as fast, so if you are going 200kmh, the top side of the tire is moving 400kmh, in relation to the road.
Oh, one more thing: since the contact patch is stationary, this also means that the rubber is chemically bonding to the asphalt.. This is stickiness. The only way it can chemically bond is if it is stationary just for a moment, while being pressed against the road with a lot of force, on small area. The bonds are just hydrogen-hydrogen bonds, weak but when the tire is sticky enough.. pieces of the tire will rip off from the surface.. That is another thing that is missing when driving on snow and ice.
By definition, the top of the tire is stationary and opposed to the asphalt, it just gets replaced very quickly.
@@gedece it gets replaced with twice the speed of the car. The part touching the road gets replaced, too, but first it moves towards the road and then away from it (following a cycloid curve), which in this case means that its speed was momentarily zero with reference to the road.
My hometown hero. Just won swedish rally
My brother in law had a Citroen 2cv with its thin tyres, and drove up a hill in winter with no problem, where others with fat winter tyres were slip sliding away, he would put that thing in second gear and off he would go, leaving everyone behind, anyone with a tyre over 175 had problems getting traction, fortunately lately we see next to no snow, again a fantastic reaction, great fun. 😊
Yes, that was the same with my now wife. Back in the 1980s she also had a 2CV and outperformed everyone in snowy conditions. But then the tires on that car looked more like disks for an angle grinder compared to the usuall tire width on other cars. Even some motobikes had wider tires. But hey, it was fun to drive that car not only in the winter. In winter it was hard because that thing didn't have a proper heating, since the car was air cooled and had only about 0.6 liter in two cylinders (she had one of the late models with the big engine and 29 hp). Not much heat to get from that....
I also must take this point; these guys driving these WRC-cars are the best drivers on this ball.
There is snow, ice, sand, stones, asphalt, light, even night and no lights but from the car, on these Narrow roads they race on. Respect.
They also face very difficult weather conditions sometimes, with fog snow heavy rain. I don’t know if you saw but on last Friday night at rally Sweden there was very difficult conditions Lappi (the guy in the video, who won the rally btw) said he couldn’t see at 50m during friday night because of the snow falling. « You have to trust the notes » he said, but damn these guys have balls of steel going this fast without even knowing where exactly they must go since they sometimes travel at 50m/s 😮 On snow ❄️ at night 🫡
The thing with the narrow tires partially refers back to the "2CV in snow and ice" video.
Both the Sweden Rally and Monte-Carlo were amazing this year, the season's off to a great start.
Esapekka Lappi is finlands weapon of choice for this wrc season. I truly hope that this is his year 💪
That diagonal staggering seems unique technique that started to be used on AWD rally cars not that long ago and probably may depend on both AWD and their differentials. IIRC stems from Monte-carlo rallies that had both snow/ice and trarmac in their stages, so some teams used such different on each side tire mix of snow & tarmac tires in diagonal staggered fashion.
The WRC will most probably host a rally in Tennessee in 2026. You should definitely cover it in person.
I believe the preference for narrow tires on Rally cars on snow/ice is due to the fact that you still drive on some kind of a road and usually you expect decent levels of snow for your tire to dig in. But if you go in Off-Road conditions on winter, you don't know what you'll meet and your chances are that if you dig in too much with the tires, you'll bank your vehicle, so you want as little pressure per surface as possible (hence, larger tires - or even tracks like in bulldozers and tanks). The same applies for snow storms, where the snow quantity falling from clouds is larger than usual. On Rally races though, the race track is still somewhat maintained and usually you don't see any high snow on it, so you'll go with what could give you the best performance (against what could allow your vehicle to get you unstuck in any situation).
narrow tires: as a student I drove an Opel Corsa and always had the last laugh when winter came "unexpectedly". With snow remaining even on the Autobahn, all the BMWs, Mercedes etc with their "breiten Schlappen"(wide slippers) as we call them, were losing their grip and "dancing" especially on the snow covered cobbled streets, whilst I was plowing thru. That was nice. And nowadays, driving a "grown up" car, I make sure to put on my winter tires in time, as I really do not want a Corsa driver laughing at me. 😂
I once bought new summer tires here in Finland and found text for all seasons North America on tire side. I was a bit surpriced cause I use studded winter tires in winter. Those on vid are only for competitions you arent allowed to use them on regular car and If I remember correct not even in Monte-Carlo rally.
vähälumisia kesiä varten
Non studded snow tyres are designed to retain snow in the large grooves as snow on snow has an adhesion value better than just rubber on snow, you already understand the principle of narrow tyres on snow as that creates more pressure/weight per square cm. Fresh snow and older compacted snow present different coefficients of friction so those setting off first may consider different tyre/stud combinations from those bringing up the rear
First time on studded tyres for me was in a rental VW New Beetle just north of the polar circle. Temperature highs were between -10 and -15 Celsius, the snowy roads 100% uncleared but rather had the snow compressed to for a pretty hard surface. It was a revelation! The Beetle was going through corners like it was on rails. If I overdid it, the ESP caught the car in no time at all. Really, really nice to drive.
Robert Kubica used to put tarmac tires instead of studded ones in road sections at Monte Carlo, to save studs for next stages.
the driver explaining won the rally last weekeend, EP Lappi. No desert on WRC.
In right conditions those tires have more grip on snow/ice than gravel tires on gravel
I was there last weekend. What an awesome event ! We rented a car with spikes to drive around and I must say we wouldn't have driven far without them. Even the main roads are covered in ice. You can drive 100kph on fast farm roads with ease. One of the best driving experience of my life. The rally was cool too lol
To me WRC ist the masterclass of handling skill in all of motorsports.
Great week-end great sweden rally.
🇸🇪
@@Rix.67 everything was here! "Easy" Monte-Carlo, triky Sweden this year. Lappi deal with it very well.
In drifting, narrow front wheels are also good chose because when you're flying with turned wheels, the front wheels grip the road better, increasing control and helping to brake when going backward. For example, take an eraser and try running it along the surface with the front and side faces. The side will bend, but it grips the surface better.
you should look at a 2CV in the snow, tiny tires and engine, but it get through
Got to love Rally.
Even on dry surface, the best tyre width is defined by the weight of the car. You basically want the narrowest tires that are strong enough not to shear away with the forces caused by the weight of the car during cornering and braking.
0:39 My man just summarized whole american automotive industry :D
Supposedly american cars were actually bad for "advanced driving". Everything that is not going straight. They don't have cars that can do this, so they don't have skill and so they like everything that does not involve steering wheel, just power :) But drag race engeneering is super insane! And u can see the whole track from one place, no chance in rally thru few villages.
@@DaweSlayer yeah it's only a joke
Ian it's like everything in America is just of a lower standard. The build standards and safety features of American cars are so substandard compared to Europe and the world of the world. When you look at how many German , Japanese and British luxury cars like Aston Martin, Bentley and Rolls Royce are exported to America. However no American cars are exported to the rest of the world. Solely made for the US market only because they wouldn't pass the European safety standards.
in german winters we had almost no problem with the CV2 :) Several vids out here on youtube. Random video on the search term "CV2 winter" is "How good is a Citroen 2CV in the snow?" in it's title.
The studs actually grabs the best on pure ice.
Not really.
@@JJ79_ What would they grab onto in powder snow?
The technical inspection in my country accepts narrower tires for winter tires.

Esapekka Lappi just won the Rally Sweden 2024! Hell yeah, we Finns rule!
Sort of related.. the amount of water a wet tyre can displace with grooves is amazing. Road can be almost dry after the car has past.
In Sweden the old regulations state that a studded tire may have a maximum of 50 studs per meter of rolling circumference with a maximum stud protrusion of 1.2 millimeters when new. There is a new supplementary set of regulations that measures road wear. Then each tire model is tested and then the number of studs in the test and protrusion when the tire is new is indicated. There is no maximum number of studs.
In Iceland, big wide tires with a little air are a must if you have to drive a car in the winter on the snow. To make it past the cracks.
You should watch a video titled "The Fastest Tractor (Full length) New Guinness World Record, Juha Kankkunen & Nokian Heavy Tires" showing a tractor running 130 km/h after snow on winter tires .Winter tires are narrower to increase the pressure on the ground, which translates into better grip. Wide tires are used for driving on sand and mud to reduce the pressure on the ground and increase the grip surface
Up here in Wisconsin we had studded tires on a car when I was a kid in the 70s. Wisconsin has banned them now tho because they tear up the roads too much. Chains are still legal tho, I'm pretty sure.
They also use specialized winter tires for the Monaco rally
In the U.S., different states have different laws regarding studded tires, what kind of studs, and when you can use them. Some states do not allow any kind of studded tires.
A big mix.
📻🙂
@IWrocker You were wondering is studded tires were street legal. That raised my curiosity as well. I live in southern Ontario, and they aren't legal here, but they've been legal in norther Ontario for as long as I can remember. I looked it up, and it turns out they are legal in all provinces with some allowing them earlier in the season, and going until either March, April or May depending on where you are. Now something interesting. Those rally tires had up to 280 studs per tire, but in the jurisdictions that allow them here, it seems you are only allowed 130 studs total for all 4 wheels. Interesting!
probably studs that long are not allowed either
@@jattikuukunen Very possibly

Walter Röhrl, 2x Rally Champion, 14 Rally wins and Group-B-Monster, giving Audi Quattro the prestige it has now. Still drives in show races with older cars at age 76.
The tires on the right can look like this after only approx. 30-50 km of driving, if there is some gravel in the grooves.
Rally tires may not be used on public roads, except in designated competitions.
6:44... You said "the used one after a long time"... That tire can look like that after one stage if there is much gravel peaking through the ice. They have to keep after the tires all the time to save them. A WRC tire isn't legal to drive if your not in competition in Sweden. To many studs and to high studs to be legal on the road. Other countrys, no idea!!
I can't imagine anywhere allowing such agressive studs, would absolutely tear up the asphalt, it would be like driving with snow chains for half the year. Maybe somewhere with only dirt roads.
I'm not American but I love NASCAR, however Rally is on a totally different level of craziness. How people don't constantly die in rally (both drivers/co-drivers and ESPECIALLY spectators) I don't know.
Have you seen the inside of a rallycar? They are way safer than a normal street car and it's way more dangerous to drive in normal traffic than in a rally competition. :)
@@dborgqvist okay sure, but what about the crazy spectators that get away too close to the zooming cars
@@Arjay404 Spectators are in alot more danger, yeah. That is one of the biggest issues with rallying today. Some people don't understand the danger they put themselves in, and the sport if a big accident would happen.
In the WRC today, there are safety officials that study live incar videos and if they spot spectators in dagerous places, the stage will be cancelled immediately.
You can’t buy rally1 spec car tires,but you can buy ”lower class” tires.
1 pirelli costs something like 500euros,so it’s like 5000-8000€/race in amateur class race just for tires.
At first, I was too distracted by the man's lack of any legs to hear what he was saying about the tires! 🤣🤣
Luckily, he moved his foot a minute and a half in - I thought they were the chair legs from the start! 😅
Narrow tires make a really big difference in the snow. Even with no studs humble VW beetle and Citroen 2CV work much better in the snow than most much fancier cars. Weight of the engine over the driving wheels makes a difference too.
You know Asfalt racing, as we call it here in Norway. there they use both rain tires and slicks, but they also use to change the camber and throw angles, this to improve the grip on the tarmac. This is not done in Rally, where the damper path is just as important, whether it is a summer rally or a winter rally. The car is often much stiffer on summer rallies than on winter rallies, even though the damper travel may be the same length. I have even tried a rally car on ice with studs, and it fits almost better than normal tires on summer roads.
When there is enough snow the Sweden rally has the highest cornering speeds because the drivers use the walls of snow either side of the road to keep the rear of the car in line.
At one point, NASCAR's official European Series planned a non-championship race on snow, however that was cancelled due to the pandemic.
narrow tyers compact the snow to a firmer base, so your grip or studs can dig in and not just churn slush.
studs are forbidden on public road in many european countries. The countries I know that studs are used on public roads in the winter season, are Sweden, Finland and Switzerland. In Switzerland the cars with studs have to have a sticker in back of the car, showing that the speed limit is 80 km/h.
Most roads in Sweden and Finland are always covered in snow. In Switzerland, snow on the roads in the mountains and mountain valleys are cleared there is still a layer of snow.
With the right equipment its saver to drive on snow than on salted roads where melted snow could turn to black-ice.
You go to Denmark (and I have seen it alot in the US as well), and just a little snowfall on the road is enough to create chaos on the road, by cars that do not have winter tires (not all season). In the US, it was mainy trucks that were laying left and right, simply because of gravitationsl balance being too high above the road and because of rear wheel drive, where the truck is the lightest - a recepy for disaster.
In Switzerland and Germany (and other countries) you loose your drivers license if caught driving without winter tires during winter season. If you are involved in an accident, no insurance will pay for the damage as well, if no winter tires during winter season.
Could be an interesting subject for you to cover ;)

The inflation problem with heat can be solved by filling the tires with nitrogen gas. It's inert and won't be as affected by heat as air, less expansion. That's why airplane tires are filled with nitrogen. And narrow tires are better in the wet to, with less risk for aquaplaning. The narrow tire have it easier pushing the water to the sides since it have shorter way to push the water out to the sides as long as you have a good thread. And rally tires aren't street legal since they'd rip up the road surface.
The more weight that you put on ice will help ice to change it from a solid state to a liquid state. The smaller the surface area of the weight, the more pressure you exert on the ice to change it to a liquid. That's why ice skate blades look the way they do.
His tires has 288 studs. In comparison, here in Norway tires larger than 16" are allowed 130 studs and those studs are also WAY smaller than on the rally tires. No wonder theres a notable difference around a track :o
also the narrow tyre gives more pressure per stud and helps it to dig in the ice.. imaging laying on spike mat versus stepping on nail :D
Greetings from Helsinki, Finland. I have 304 studs of my bike tyres. I have Nokia Tyres Hakka 300 tyres. Best tyres of winter cykling. 👍❤
This reminds me the ice racing motorcycle tires. Pure nightmare fuel.
I lived in Finland for 10 years and they have a law that says you have to have winter tires on your car from 01.11 to 31.03>
they have two kinds of tires ones with studs in (NOT as big as the studs rally cars use) for mostly Icy roads and snow tires, these do not have studs but are better at gipping to just snow
and they make a really big different
How's the sim pedals and wheel going? Are you still doing that video?
The tires aren’t street legal but the cars get a special permit for temporary use (in Sweden).
Isnt there maximum average speed limit on rally stages, like 150 kilometers or more before that stage gets ruled out because of safety? And a limit of how many tires allowed per car as Esapekka Lappi mentions tyre rotation, as otherwise the put new ones on for every stage?
When you look at the tires that are used on rally cars in winter rallies, there's no need to be surprised. They have such spikes that it's a wonder if they don't bite into ice or harder snow
You should check out ice racing, they are like rally snow/ice tires on steroids, the studs on those tires are INSANE!
Oh, just 28 mm.
ice bike races, on round tracks in a stadium, are insane.
a hedgehog looks smooth in comparison :-)
In FInland those used rally tires are abundent. every village where there is icetrack in winter, there is atleast one who has those. no roadlegal tho, just icetrack and racing use. you can pick up dryrotted rallyspike tires for like 50-100e a round. there is no use for those in real racing anymore so they are problem waste to them but a nice score for icetrack drivers.
In the Nordic countries studded tyres are legal on street cars while in central europe like germany and austria they are not. So it's pretty scary transversing the alps on summer tyres. I use not studded winter tyres in Stockholm because they have a softer rubber mixture than summer tyres which gives me a good grip on winter surfaces, except on polished ice, and doesn't wear down the tarmac on snow-free roads. But my winter tyres are slimmer than the ones I use in the summer.
Narrower tyres are not only better in snow but also mud
you should check out some Hard Water Racing. both cars and bikes. (HWR) is racing on a frozen lake or body of water. theres different classes - rubber to ice, stud to ice rear or front wheel, and and 4 stud to ice... huge difference no stud and studded in times. the same can be said for bike racing on ice too. for cars and bikes here it mostly circle track racing. hard to make a road track with equipment on the ice and not fall through as everything depends on ice thickness. also the stress put down on the ice to so you prefer to build it in shallow water like a bay. we keep the cars to 4cyl and the weight down and both the car clubs and the bike clubs work hand in hand to due a full weekend of racing. ave temps here on a nice day is -20C or -30c but if there is a wind then its much worse, lol
Should come check out Rally Estonia / Rally Finland in person and taste some of the awesome local beers and be part of the whole rally crowd for once in a lifetime experience. With Norwegian Air, plane tickets from Chicago/NY to Norway/Finland/Latvia used to be like 200$.
Beer? In Finland? Do they still have these type classes from I to IV? We always called it "children's amusement water" and smuggled pallets of German beer into Finland 🤣
@@solidsteel3634 yea the Finns are importing Estonian beers in masses, so now they got good beer too :D
Actually they tested street tires and it didn‘t make a big difference if they used narrow or wider tires. The Problem is the compound. It makes the difference, also it depends on what kind of snow.
But never try a summer or all season tire in real snow.

Remember how good the Citroën CV2 went on snow? Skinny tyres! 😉
first time i see kph is really funny. 200 kmh is how we write this down
Look at how thin tires are in truck and tractor pulls, when going through mud. They are thinner. Even the tires that look wider, once they start spinning, will become thinner.
if you wana buy those they are 600e one tire and in typigal national rally in here dinland we use 10 on one rally :D
"finland"
It's time you made a trip to Europe to experience a rally event for your self
I love mountain biking on snow and ice (Switzerland) when most people leave their bicycle in the basement. It's not 200 km/h but nevertheless slippery :-)
Wow, the first Time i see you without a Cap 😂
