I would love to see a deep dive like this into top of the range racing slicks! Like F1 tyres, perhaps. What are their rolling resistance and noise profile like? This was fascinating
Nicely done and quite informative. It would be nice to "go behind the scenes" so-to-speak to see how tires are developed in the lab as well as how they are actually manufactured.
One additional thing is that these tires are also rated and tested for high speed performance. All terrain tires would be at most H rated tires which means must be able to sustain speeds of up to 130mph or 210kmh. This adds another layer of complexity in balancing off road and on road performance. Great video 👍🏼
I remember reading an article about rubber compounds having about 20C of optimal operational range. +10 - +30C for summer tires. -10 - +10C for studded winter tires. -20 - 0C for studless winter tires. Temperatures bellow optimal means the tire get to stiff with more slippage as a result, and above means to soft with higher wear. How do do all terrain tires handle this problem?
I've only ran All-Terrain tires on my truck since I bought it since it sees a little bit of both on and off-road driving. I will say that even some of the more affordable options fit the intended role of such type of tire very well. The tires I currently have on my truck are the General Grabber A/Tx. The tread pattern is very similar to the BF Goodrich KO series, but actually has more sipes per tread. On-road, the impact on fuel economy hasn't been very noticeable, particularly with highway driving. As for noise, I have not noticed any excessive noise from the tires (granted, my truck's exhaust setup is very loud, so the difference between this A/T vs a highway tire is likely maske by the exhaust). Off-road, they've performed very well, even in mud. My buddy, who goes off-roading more regularly than I do and recommended the Generals to me, reported that they handled snow exceptionally when he had to drive home from one of his adventures in a snowstorm. In fact, he actually prefers the General A/Tx over the Bf Goodrich. All of that being said, it's not surprising how much thought has to be put into the design process of this type of tire.
You are kinda on kick about tires right now. May I suggest you go and talk to O'Neil racing or DirtFish about the unique needs of rally tires. You think all-terrains have a tough job.
Not as in depth but I do share some good details on them here, with Subaru's rally team! ua-cam.com/video/1971DmZC41s/v-deo.html Edit: Worth noting, while the rally tire environment is certainly tough, rally tires aren't so worried about noise, ride comfort, rolling resistance, and a tread that lasts 60k miles. OE road tires really do have an incredibly difficult challenge to overcome.
Well, tires are very fascinating, the only component that connects the car to the road. Especially high performance tires face various unique engineering challenges.
My big thing I've noticed I had theses an I'm on Ko2s now. They both seem to like to hydroplane. I'm due for tires at the end of the summer. Gonna try the wildpeaks.
@@thresher455 how’s the road noise on these vs the KO2’s that you have now? I have KO2’s and thinking on buying the dynapro next to try them out. Thank you
Ko2s are great at hydroplaning and not grabbing in general. They also wear out really quick - got 14k on my Raptor's stock K02s, which was average for those of us offroading. Got cooper st maxes and they are much better. A friend got the AT2 and really likes them. My tires have way more grip everywhere, but are more loud than I like.
BFG factory employee here. The customer expectations for NVH (Noise, Vibration, and Handling) for AT tires has increased exponentially in recent years. The KO2 was tweaked to improve it over the years, but needed a design step change for KO3 deployment. The company launched the Trail Terrain line to provide a more road-friendly option for consumers who honestly only want occasional/mild off-road use. Edit: almost forgot. OEM’s HAVE to improve fuel economy. It is FAR easier to get 1-2% less rolling resistance than increase ICE efficiency or vehicle aero by the same amount. This is why silica tread compounds have been proliferated (but are a nightmare to mix/extrude).
Please give me some details on how the BFG A/T KO3 tyres are an improvement over KO2s I have today (that are nice, but disappointing in the mud and snow). I am thinking of purchasing the new KO3 tyres. Thank you!
I live in rural Western Australia, and it's awesome to hear about the engineering that goes into the tires that pretty much everyone religiously gets for their cars.
I watched another video that showed tire deformation over small rocks. The less wide tires seemed to deform more than wide tires. I bought a diesel truck 09 gmc two years ago that came with new mud terrain tires and 18” non stock rims. They where very loud and the cabin noise and vibrations where horrible. I swapped them out before they needed to be replaced because it was very uncomfortable with vibrations and noise. I got new rims and tires. 16” rims the smallest rim that fits and 33” tires that are 9” wide. Toyo ATs. My family enjoys riding in the truck now. It’s quite and the vibrations are all gone. These tires at 60psi deform and the tire soaks up little bumps. Night and day between 18” rims with muds and 16” rim with ATs. With the new set up there is a bulge where the tire meets the road adding to the tire deforming and complying. So nice. It changed the whole experience. I barely drive it. It’s just used to tow a boat or truck needed trips.
Kenda Klever R/T! Done and done ‼️Best truck tire I ever rode on. Love the on road ride and drive, off road traction would be impressive for a mud tire much less a hybrid like this. 3 peak rated too.
The noise reduction by different sized blocks doesn't reduce total noise, but spreads it out spectrally. Think 5 pianos with the C key being hit on all 5, V. 5 different notes being hit. Same total noise - just in different spectral "buckets" so less intense at any given bucket and so less annoying.
Very much enjoyed this. The Trailblazer needs new tires before winter.... these are now at the top of the list to research...very good presentation. Just to mention tires are a fascinating subject and way to overlooked from bicycles to semi tractor and trailer rigs. Thanks again.
I live in Southern California and off-road all most daily. It’s a half mile to my house on dirt. My wife and I run fire roads constantly and my favorite longest lasting tire that takes the most abuse has been the toyo open country at 3.
I'd argue that tire noise is not so much related to air pumping but more to tire/compound rigidity. On tire contact with the road during rolling, the surface of the tire comes into contact aggressively with the asphalt which generates vibration and mechanical stress. When the compound is hard, it won't absorb that stress and attenuate it but rather will distribute the vibration along the surface of the tire and further will be transmitted into the air surrounding the tire and finally will reach the ear. On the other hand, when a soft compound tire comes into contact with the asphalt, the mechanical stress and vibrations generated by the impact will be absorbed by the soft compound and the amount of remaining vibration which will be transmitted into the air around will be much less, resulting in less noise. What I say is that you can have identical tires when it comes to tread but different compounds and the noise they make would be very different. This can be best tested in void having a microphone inside the tire. The harder tire will generate higher noise inside the tire even though outside the tire is no air: just void.
We a JLU Willy’s Wrangler that came with the Firestone mud terrains and they look cool but they are definitely really bad in the rain, and the steering response issue you mentioned with the big blocks also translates into weird dry braking performance.
Have you had experience with the prior AT2? I have those currently and am curious what changed to make the Xtreme. Both tread patterns look quite similar and I think the standard AT2 is still being made.
@@ALMX5DP I do not, had to get new tires for my truck and researched all the available all terrains and for the cost, 70k mileage warranty, 3 peak rated and weight I thought the Dynapros were the best option. A buddy that owns a repair shop said that he's seen guys with 80-100k miles on these. I wanted the xtreme for more tread depth as in Wisconsin we get a decent amount of snow and as soon as most tires get below 5-6/32" they get pretty sketchy.
@@Hangovna How the noise from the AT2 on the highway? What tires dod you have prior on the Ram and how would you compare noise and ride quality of the two tires?
@@4Cabin They are louder than factory but I find all terrains get a smidge quieter as you put some miles on them. I had factory junk Bridgestone tires that only lasted 30k which were definitely quiet and smooth but offered little off road traction so these are louder/stiffer but still not bad. Factory size was 275/55R20 (41ish pounds) and I went up to 275/60R20 (43ish pounds). Fuel econ is maybe 0.5-1mpg less.
@@Hangovna Thanks. My 2022 GMC Sierra came with the Bridgestone Duller AT RHS. They are smooth and quiet but really lack off road capability and are not good at all in snow/slush conditions. Living in New Hampshire these lacking capabilities are a real problem. So thats why iI interested in 3PMS rated AT tires like the AT2 Extreme. I'm also considering the new Kumho AT52, Vredestein AT, BFG Trail Terrain, Hercules ATX Journey and the Nokian Outpost AT. There are others but I also dont want tire noise to become an issue since we use the truck for long road trips.
Great video. Thanks. My tyre choice is yokohama geolander AT G015. The hankook in this video is very similar and would offer all the same noise ride and grip qualities.
Tires have come so far in my lifetime. I remember going on family vacations 60 years ago and there were almost always tire failures. It probably didn't help that my dad packed the station wagon to the gills, put 2 or 3 canoes on the roof, a boat and trailer out back and drove like a bat out of hell. Anyway, my relevant comment is I have had several All Terrain tires that were remarkably quiet. The Pirelli Scorpion tires on my RAM 1500 are basically inaudible. Now there is a fair amount of wind noise but that's typical for the vehicles that use All Terrain tires.
All terrain tires specifically those that are three-peak snow rated are my favorite tire for all of my vehicles. Goodyear Wranglers or if I need a smaller tire then Yokohama Geolander G015's either tire is great for basically any vehicle type dispite what conventional wisdom may say.
There are also small 2/32" protrusions embossed from the bottom of the grooves, these are called rock ejectors and they also help throw any stones out!
Usually the 2/32” nubs are wear indicators. Most modern tires have them since the 80’s. When 2/32 tread depth is all that remains, it’s time to replace the tire. 👊
My mechanic turned me on to Hankook tires 15+ years ago when I was looking for a summer-only set for my 540i. They definitely fly a little under the radar in the average person's awareness of tire brands. As Kia's and Hyundai's became more popular for the a to b car consumer, Hankook definitely became more popular here in the states, whether or not anyone actually realized it. As soon as the oem Goodyear's on my Grand Cherokee hit about 40k this summer, a set of the dp xtremes are going on. I love that they have them available in white letter sidewalls too. Helps break up the black blob hanging off each corner of your car.
Had the Hankook DynaPro AT-M and AT2 Extremes before and they're great tires. You can't go wrong with them. Recently put LT265/70/17 [E load/10 Ply] Sumitomo Encounter AT on a 2019 Grand Cherokee Laredo E and they're also an amazing tire. They're the milder, more road mannered version of the Falken Wilpeak AT3W's made by Sumitomo, the parent company of Falken. They actually outperform the Falken Wildpeak's, Hankook DynaPros and Kumho Road Venture AT52's. My favorite all terrain tires so far have been Nokian Outpost AT, Falken Wildpeak AT3W, Hankook DynaPro AT-M / DynaPro AT2 Extremes and now the Sumitomo Encounter AT's. Can't go wrong with any of them to be honest. I've tried so many different brands and types of tires so far but those are my favorite all terrain tires. What size are you getting them in and what's your usage going to be like?
In Poland we use to say: "If it's good for everything, it's good for nothing" You can't have everything. If you have good offroad traction, you won't get quiet and low rolling resistance on asphalt.
Yep, the same can be said about any "2 in 1" products - for example the all seasons tyres are worse during winter/summer than the specialised winter/summer tyres.
The difficulty becomes apparent for those that have ran several diiferent A/T's as the best are truly impressive [as all-arounders] while the worst have several dramatic flaws like short tread life, loud like M/T's, not being decent on OR off-road, bad in snow/ice, and so on. Very happy with my Falken Wildpeak AT3/W on 18 Ram 1500. I have the P's and not LT which were cheaper, lighter, softer riding, and just more practical for my usage as a daily driver, mostly unloaded and infrequent towing but plenty off-road occasions.
Michelin does this significantly better than any other manufacturer with the LTX A/T2. They are not even in the same league as what Hankook has to offer. They also have the same warranty and I get 85,000 miles out of a set.
I got an f350 and aftermarket tires rims and it wears in such a way that when driven slow it actually cuts into the ground they call it cupping but feel it it's sharp
I don't wanna sound like some zealot to a corporation, but co-incidentally last month I bought some hankook's for my sleeper mini, my first ever set from this brand, and so far I can confidently say they are some of the best tyres I've ever used. Very progressive, tons of lateral grip but with great feedback, it feels intuitive to judge the limit. what's more they are surprisingly comfortable which I wasn't expecting.
i don't understand why you Americans don't change to winter tyres when temperatures drop down to freezing. In Sweden it is the law. That's why you never see those winter videos with cars slipping down frozen streets like pinball balls from Sweden. Changing to winter tyres when necessary saves money by reducing accidents significantly.
One point on efficiency not mentioned in the video: RANGE! If you are really going exploring gas stations can be few and far between and carrying extra gas is not exactly easy (plus adds weight to the rig) so an extra 15% MPG is huge.
The "all terrain" tire, currently the shorten nomenclature from the original "kinda sucks in all terrain" tire. I see ATs as just an aesthetic upgrade. They are almost as loud and heavy as mud tires with no where near the advantage off road. You can get mud tires that will last just about as long and they are usually the same price or cheaper than ATs. Some companies have started making "hybrids" where they make pretty aggressive tread on the outside tread pattern while keeping the inside pattern pretty tight; this allows you to slightly over inflate for the road, keeping the bigger lugs from contacting the asphalt, but one you air down, they can help engage terrain. It's a step in the right direction, but still isn't perfect.
Great Video. I have to say that I had to walk away from the Dynapro tires and switch over to another brand due to the Hankook tires clogging with mud and snow and not cleaning themselves adequately. The Dynapro tires had good dry traction, never gave me any issues on the wet roads and performed admirably when running on a solid sheet of ice and other four wheel drives were not moving. But having the tires clog up and turn into slicks when trying to travel through more than 4 inches of snow was an absolute deal breaker and I cannot put them on my truck. If I did not have to make regular trips across the Allegheny Plateau or across I68 in the middle of winter then this would be less of an issue, but nobody want to be on the highway when you are caught in a few inches of snow and the vehicle becomes hard to control because of the snow. Perhaps the AT2 Extreme may be a better tire than the AT2s that were on my truck from the factory, but when they cost the same as a better rated competitor, you make the switch and have the snow traction that you need.
@@c.garison3770 I think in snow you want snow to stick between the treads, snow on snow contact when spinning increases grip. Wider groove tires like Toyo's will help with this.
I was torn between the Dynapros, Falkens and Cooper a/t tires for my 4x4. Went with the Falkens 1st go round because i liked how they looked best. Super quiet tires. This time i have Goodyear Wrangler Ultra Terrain a/ts and they're the most aggressive tire you can get next to a legit m/t. They are very quiet as well with the exception of slow driving on very smooth roads. They will hum just a wee bit. I will be getting another set when these go.
High load (D+) all terrains I like nitro terra grapplers. For load C all terrains the BFG KO2 is undefeated. I hear these hankooks are pretty affordable though.
C rated K02s come stock on raptors and they are garbage. My set lasted 14k, and that was about average. No grip anywhere pretty much. Got some Cooper ST maxes and despite being way more aggressive off-road they have similar or better grip on road, which is sad. They are a bit louder than I'd like tho.
@@T4nkcommander I bought my raptor at 53k on it original tires on the front new ones on the back (dealer special huh). Put about 10k on it then I got 4 brand new BFGs. Got about 13k on them now and they are wearing in perfectly
@@krisramos7453 how much high speed offroading do you do? They don't last long under the conditions the truck was built for, but I reckon the "raptor specific" version saves Ford money and gets better mileage, so there's that at least.
@@T4nkcommander my truck does either beach running (15mph speed limit on most beaches here so I’m not flying) or crawling through woods trails. Also thousands of miles towing an aluminum boat. Other wise it’s a lot of highway
The more you understand the abuse tires are designed to deal with, the more amazing it is how they work as well and as long as they do.
Yeah, especially for the cost. I know they are expensive but when you consider the design, materials, sizes, liability, shipping, marketing, etc. It's amazing you can pick up 35" or 35" tires for what you can.
And not just last a long time but be reliable. Last thing you want is a bunch of tires randomly blowing up on the road
Tires blow my mind🤯 always have. Even the basic expectations, like just staying on the bead and not constantly failing.

I remember reading an article about rubber compounds having about 20C of optimal operational range.
+10 - +30C for summer tires.
-10 - +10C for studded winter tires.
-20 - 0C for studless winter tires.
Temperatures bellow optimal means the tire get to stiff with more slippage as a result, and above means to soft with higher wear.
How do do all terrain tires handle this problem?
I had Hankook Dynapro ATM on my 1999 Jeep Grand Cherokee and loved them.
I've only ran All-Terrain tires on my truck since I bought it since it sees a little bit of both on and off-road driving. I will say that even some of the more affordable options fit the intended role of such type of tire very well.
The tires I currently have on my truck are the General Grabber A/Tx. The tread pattern is very similar to the BF Goodrich KO series, but actually has more sipes per tread. On-road, the impact on fuel economy hasn't been very noticeable, particularly with highway driving. As for noise, I have not noticed any excessive noise from the tires (granted, my truck's exhaust setup is very loud, so the difference between this A/T vs a highway tire is likely maske by the exhaust).
Off-road, they've performed very well, even in mud. My buddy, who goes off-roading more regularly than I do and recommended the Generals to me, reported that they handled snow exceptionally when he had to drive home from one of his adventures in a snowstorm. In fact, he actually prefers the General A/Tx over the Bf Goodrich.
All of that being said, it's not surprising how much thought has to be put into the design process of this type of tire.
You are kinda on kick about tires right now. May I suggest you go and talk to O'Neil racing or DirtFish about the unique needs of rally tires. You think all-terrains have a tough job.
Not as in depth but I do share some good details on them here, with Subaru's rally team! ua-cam.com/video/1971DmZC41s/v-deo.html
Edit: Worth noting, while the rally tire environment is certainly tough, rally tires aren't so worried about noise, ride comfort, rolling resistance, and a tread that lasts 60k miles. OE road tires really do have an incredibly difficult challenge to overcome.
Well, tires are very fascinating, the only component that connects the car to the road. Especially high performance tires face various unique engineering challenges.
@EngineeringExplained if I hike the trail with the mountain goat carrying my luggage, the grip is always there.
@@DefinitelyNotEmmaNot necessary. All components you can touch on the outside can touch the road, but that's less favourable.
@@Donnerwamp lmao, true
From the years of your amazing videos, this may be one of the one of the most informative. Thank you so much.
I have these on my 4runner. So far I'm liking them.
My big thing I've noticed I had theses an I'm on Ko2s now. They both seem to like to hydroplane. I'm due for tires at the end of the summer. Gonna try the wildpeaks.
@@thresher455 how’s the road noise on these vs the KO2’s that you have now? I have KO2’s and thinking on buying the dynapro next to try them out. Thank you
Ko2s are great at hydroplaning and not grabbing in general. They also wear out really quick - got 14k on my Raptor's stock K02s, which was average for those of us offroading.
Got cooper st maxes and they are much better. A friend got the AT2 and really likes them. My tires have way more grip everywhere, but are more loud than I like.
An excellent explanation ! Concise and easy to understand . I hope to see one on how the new All Weather tires compare to the All season tires 🤓
Tires are incredibly cool! I look forward to more videos like this one. Thanks for the excellent content!
BFG factory employee here. The customer expectations for NVH (Noise, Vibration, and Handling) for AT tires has increased exponentially in recent years. The KO2 was tweaked to improve it over the years, but needed a design step change for KO3 deployment.
The company launched the Trail Terrain line to provide a more road-friendly option for consumers who honestly only want occasional/mild off-road use.
Edit: almost forgot. OEM’s HAVE to improve fuel economy. It is FAR easier to get 1-2% less rolling resistance than increase ICE efficiency or vehicle aero by the same amount. This is why silica tread compounds have been proliferated (but are a nightmare to mix/extrude).
I have no doubt that all that abrasive silica imposes a lot more wear on your moulds and other tooling as well. But that's the tradeoff we make.
Please give me some details on how the BFG A/T KO3 tyres are an improvement over KO2s I have today (that are nice, but disappointing in the mud and snow).
I am thinking of purchasing the new KO3 tyres.
Thank you!
I live in rural Western Australia, and it's awesome to hear about the engineering that goes into the tires that pretty much everyone religiously gets for their cars.
This is so interesting. I am never tired of learning about cars from you! Thank you 😊
I've had my hankook dynopro at2 lt for 50,000k.. nearly 4 years. Awesome tyre
Thanks for explaining the reasons for various tire design features.
I watched another video that showed tire deformation over small rocks. The less wide tires seemed to deform more than wide tires.
I bought a diesel truck 09 gmc two years ago that came with new mud terrain tires and 18” non stock rims. They where very loud and the cabin noise and vibrations where horrible. I swapped them out before they needed to be replaced because it was very uncomfortable with vibrations and noise. I got new rims and tires. 16” rims the smallest rim that fits and 33” tires that are 9” wide. Toyo ATs. My family enjoys riding in the truck now. It’s quite and the vibrations are all gone. These tires at 60psi deform and the tire soaks up little bumps. Night and day between 18” rims with muds and 16” rim with ATs. With the new set up there is a bulge where the tire meets the road adding to the tire deforming and complying. So nice. It changed the whole experience. I barely drive it. It’s just used to tow a boat or truck needed trips.
Tinkerers adventure was the skinny vs wide tire video
That BRONCO looks so SICK. 🤩
tie blocks! learned something today!!
Kenda Klever R/T! Done and done ‼️Best truck tire I ever rode on. Love the on road ride and drive, off road traction would be impressive for a mud tire much less a hybrid like this. 3 peak rated too.
Simple, sweet, informative, loved the video, I’ve been running hankook atms on my old Toyota been looking at some at extremes for my new ford!
The noise reduction by different sized blocks doesn't reduce total noise, but spreads it out spectrally.
Think 5 pianos with the C key being hit on all 5, V. 5 different notes being hit.
Same total noise - just in different spectral "buckets" so less intense at any given bucket and so less annoying.
That was the Best description of tire features I have ever heard. Thank you!
Very much enjoyed this. The Trailblazer needs new tires before winter.... these are now at the top of the list to research...very good presentation. Just to mention tires are a fascinating subject and way to overlooked from bicycles to semi tractor and trailer rigs. Thanks again.
I live in Southern California and off-road all most daily. It’s a half mile to my house on dirt. My wife and I run fire roads constantly and my favorite longest lasting tire that takes the most abuse has been the toyo open country at 3.
I love all terrain tires. We have a set of Falken Wildpeak AT3W on our jeep and they're awesome.
Yes I have them on my p38 Range Rover. Excellent traction and good road manners.
That is a great video on tyres Jason. Most informative. They work well in Australia too.
I got a set if these several months ago on my 07 4Runner. I love this tire so far. AND it was one if the cheapest options. I am very impressed so far.
Did you get this new "HankookDynapro AT2 Xtreme" or the "HankookDynapro AT2 RF11"? AT2 Xtreme seems not that cheap.
@@LionRunner the xtreme. It was when I bought it lol
@@xlxphoenixkingxlx lucky you...!!!!!😀😀 Now its more expensive than the Toyo OC 285/70R17SL I bought few months back.
I'd argue that tire noise is not so much related to air pumping but more to tire/compound rigidity. On tire contact with the road during rolling, the surface of the tire comes into contact aggressively with the asphalt which generates vibration and mechanical stress. When the compound is hard, it won't absorb that stress and attenuate it but rather will distribute the vibration along the surface of the tire and further will be transmitted into the air surrounding the tire and finally will reach the ear.
On the other hand, when a soft compound tire comes into contact with the asphalt, the mechanical stress and vibrations generated by the impact will be absorbed by the soft compound and the amount of remaining vibration which will be transmitted into the air around will be much less, resulting in less noise.
What I say is that you can have identical tires when it comes to tread but different compounds and the noise they make would be very different.
This can be best tested in void having a microphone inside the tire. The harder tire will generate higher noise inside the tire even though outside the tire is no air: just void.
We a JLU Willy’s Wrangler that came with the Firestone mud terrains and they look cool but they are definitely really bad in the rain, and the steering response issue you mentioned with the big blocks also translates into weird dry braking performance.
Just bought these xtremes, pretty happy with them on my RAM 1500.
Have you had experience with the prior AT2? I have those currently and am curious what changed to make the Xtreme. Both tread patterns look quite similar and I think the standard AT2 is still being made.
@@ALMX5DP I do not, had to get new tires for my truck and researched all the available all terrains and for the cost, 70k mileage warranty, 3 peak rated and weight I thought the Dynapros were the best option. A buddy that owns a repair shop said that he's seen guys with 80-100k miles on these. I wanted the xtreme for more tread depth as in Wisconsin we get a decent amount of snow and as soon as most tires get below 5-6/32" they get pretty sketchy.
@@Hangovna How the noise from the AT2 on the highway? What tires dod you have prior on the Ram and how would you compare noise and ride quality of the two tires?
@@4Cabin They are louder than factory but I find all terrains get a smidge quieter as you put some miles on them. I had factory junk Bridgestone tires that only lasted 30k which were definitely quiet and smooth but offered little off road traction so these are louder/stiffer but still not bad. Factory size was 275/55R20 (41ish pounds) and I went up to 275/60R20 (43ish pounds). Fuel econ is maybe 0.5-1mpg less.
@@Hangovna Thanks. My 2022 GMC Sierra came with the Bridgestone Duller AT RHS. They are smooth and quiet but really lack off road capability and are not good at all in snow/slush conditions. Living in New Hampshire these lacking capabilities are a real problem. So thats why iI interested in 3PMS rated AT tires like the AT2 Extreme. I'm also considering the new Kumho AT52, Vredestein AT, BFG Trail Terrain, Hercules ATX Journey and the Nokian Outpost AT. There are others but I also dont want tire noise to become an issue since we use the truck for long road trips.
Great video. Thanks. My tyre choice is yokohama geolander AT G015. The hankook in this video is very similar and would offer all the same noise ride and grip qualities.
That tire and wheel combo looks good on the Bronco
Solid video as always! Care to explain weight distributing trailer hitches next?
Tires have come so far in my lifetime. I remember going on family vacations 60 years ago and there were almost always tire failures. It probably didn't help that my dad packed the station wagon to the gills, put 2 or 3 canoes on the roof, a boat and trailer out back and drove like a bat out of hell.
Anyway, my relevant comment is I have had several All Terrain tires that were remarkably quiet. The Pirelli Scorpion tires on my RAM 1500 are basically inaudible. Now there is a fair amount of wind noise but that's typical for the vehicles that use All Terrain tires.
My favorite. I have these on my Colorado now and had them on my F150 previously.
Well hello, two of my favourite things
I love Hankook. i am running Dynapro XT. (Hybrid / Rugged)
Great job explaining the tire design trade-offs. I learned a lot. Thank you
Great video. I just bought a truck with these tires installed on it. Great looking tire. Hope they perform just as well.
I didn't know anything about tires going into this video, but this is cool to know. Thank you.
I love tire tech videos!
All terrain tires specifically those that are three-peak snow rated are my favorite tire for all of my vehicles. Goodyear Wranglers or if I need a smaller tire then Yokohama Geolander G015's either tire is great for basically any vehicle type dispite what conventional wisdom may say.
Just in time for getting some new tires in my truck!
Outstanding video !!
Thank you !!
amazing video 👍
Weirdly I noted a VW golf in my works car park had a snow tyre on it and it's 25°c outside right now. Then this video popped up 😅
You could also elaborate on how the tread blocks can “lock” to create extra stiffness in certain motions.
Thanks 4 all the great information. I am going to buy new tires 4 my Tacoma soon. This video is a lot of help. 👍🖖💪
There are also small 2/32" protrusions embossed from the bottom of the grooves, these are called rock ejectors and they also help throw any stones out!
Usually the 2/32” nubs are wear indicators. Most modern tires have them since the 80’s.
When 2/32 tread depth is all that remains, it’s time to replace the tire.
👊
Yes! They do have these on the MT tires.
My mechanic turned me on to Hankook tires 15+ years ago when I was looking for a summer-only set for my 540i. They definitely fly a little under the radar in the average person's awareness of tire brands. As Kia's and Hyundai's became more popular for the a to b car consumer, Hankook definitely became more popular here in the states, whether or not anyone actually realized it. As soon as the oem Goodyear's on my Grand Cherokee hit about 40k this summer, a set of the dp xtremes are going on. I love that they have them available in white letter sidewalls too. Helps break up the black blob hanging off each corner of your car.
Had the Hankook DynaPro AT-M and AT2 Extremes before and they're great tires. You can't go wrong with them. Recently put LT265/70/17 [E load/10 Ply] Sumitomo Encounter AT on a 2019 Grand Cherokee Laredo E and they're also an amazing tire. They're the milder, more road mannered version of the Falken Wilpeak AT3W's made by Sumitomo, the parent company of Falken. They actually outperform the Falken Wildpeak's, Hankook DynaPros and Kumho Road Venture AT52's. My favorite all terrain tires so far have been Nokian Outpost AT, Falken Wildpeak AT3W, Hankook DynaPro AT-M / DynaPro AT2 Extremes and now the Sumitomo Encounter AT's. Can't go wrong with any of them to be honest. I've tried so many different brands and types of tires so far but those are my favorite all terrain tires. What size are you getting them in and what's your usage going to be like?
In Poland we use to say: "If it's good for everything, it's good for nothing" You can't have everything. If you have good offroad traction, you won't get quiet and low rolling resistance on asphalt.
Yep, the same can be said about any "2 in 1" products - for example the all seasons tyres are worse during winter/summer than the specialised winter/summer tyres.
I am a mechanical engineer and am still amazed at tire technology.
Thank you Jason, another excellent video.
The difficulty becomes apparent for those that have ran several diiferent A/T's as the best are truly impressive [as all-arounders] while the worst have several dramatic flaws like short tread life, loud like M/T's, not being decent on OR off-road, bad in snow/ice, and so on.
Very happy with my Falken Wildpeak AT3/W on 18 Ram 1500. I have the P's and not LT which were cheaper, lighter, softer riding, and just more practical for my usage as a daily driver, mostly unloaded and infrequent towing but plenty off-road occasions.
Great Info..
Michelin does this significantly better than any other manufacturer with the LTX A/T2. They are not even in the same league as what Hankook has to offer. They also have the same warranty and I get 85,000 miles out of a set.
The problem for Michelin, is that it doesn't have the aggressive tread for the "look". But I agree with you.
Thank you for reading out loud their sales brochure
I got an f350 and aftermarket tires rims and it wears in such a way that when driven slow it actually cuts into the ground they call it cupping but feel it it's sharp
You know you're going to see some quality content if EE releases a video on tires.
Looks like I want at2 extremes now. Maxxis razar AT’s are all the rage here in Australia at the moment, good tire bad wear.
I don't wanna sound like some zealot to a corporation, but co-incidentally last month I bought some hankook's for my sleeper mini, my first ever set from this brand, and so far I can confidently say they are some of the best tyres I've ever used. Very progressive, tons of lateral grip but with great feedback, it feels intuitive to judge the limit. what's more they are surprisingly comfortable which I wasn't expecting.
Thank you for enlightment! 👌

Yay! Love your tire videos!
Great subject matter as always. Nice job on this one.
i don't understand why you Americans don't change to winter tyres when temperatures drop down to freezing. In Sweden it is the law. That's why you never see those winter videos with cars slipping down frozen streets like pinball balls from Sweden. Changing to winter tyres when necessary saves money by reducing accidents significantly.
Amazing video and topic!!
Got an mv6 ex poolice car. It's buggered, but I've a doner engine to collect.... looking forward to the omega project. They are awesome cars😊
Thanks for your contents
Tires are the #1 vehicle upgrade 👌
Great vid! Thank you!
One point on efficiency not mentioned in the video: RANGE! If you are really going exploring gas stations can be few and far between and carrying extra gas is not exactly easy (plus adds weight to the rig) so an extra 15% MPG is huge.
I find this oddly fascinating. Thanks for the info!
The "all terrain" tire, currently the shorten nomenclature from the original "kinda sucks in all terrain" tire. I see ATs as just an aesthetic upgrade. They are almost as loud and heavy as mud tires with no where near the advantage off road. You can get mud tires that will last just about as long and they are usually the same price or cheaper than ATs. Some companies have started making "hybrids" where they make pretty aggressive tread on the outside tread pattern while keeping the inside pattern pretty tight; this allows you to slightly over inflate for the road, keeping the bigger lugs from contacting the asphalt, but one you air down, they can help engage terrain. It's a step in the right direction, but still isn't perfect.
Great Video. I have to say that I had to walk away from the Dynapro tires and switch over to another brand due to the Hankook tires clogging with mud and snow and not cleaning themselves adequately. The Dynapro tires had good dry traction, never gave me any issues on the wet roads and performed admirably when running on a solid sheet of ice and other four wheel drives were not moving. But having the tires clog up and turn into slicks when trying to travel through more than 4 inches of snow was an absolute deal breaker and I cannot put them on my truck. If I did not have to make regular trips across the Allegheny Plateau or across I68 in the middle of winter then this would be less of an issue, but nobody want to be on the highway when you are caught in a few inches of snow and the vehicle becomes hard to control because of the snow. Perhaps the AT2 Extreme may be a better tire than the AT2s that were on my truck from the factory, but when they cost the same as a better rated competitor, you make the switch and have the snow traction that you need.
I don't drive in snow but I've also had my AT2's clog up with mud. Seems like a downfall of the design. Which tire did you swap to?
@@NiSE_Rafter I moved to the Toyo AT3.
@@c.garison3770 I think in snow you want snow to stick between the treads, snow on snow contact when spinning increases grip. Wider groove tires like Toyo's will help with this.
I was torn between the Dynapros, Falkens and Cooper a/t tires for my 4x4. Went with the Falkens 1st go round because i liked how they looked best. Super quiet tires. This time i have Goodyear Wrangler Ultra Terrain a/ts and they're the most aggressive tire you can get next to a legit m/t. They are very quiet as well with the exception of slow driving on very smooth roads. They will hum just a wee bit. I will be getting another set when these go.
can you reverse the tires so no white wall?
High load (D+) all terrains I like nitro terra grapplers. For load C all terrains the BFG KO2 is undefeated. I hear these hankooks are pretty affordable though.
C rated K02s come stock on raptors and they are garbage. My set lasted 14k, and that was about average. No grip anywhere pretty much. Got some Cooper ST maxes and despite being way more aggressive off-road they have similar or better grip on road, which is sad. They are a bit louder than I'd like tho.
@@T4nkcommander I bought my raptor at 53k on it original tires on the front new ones on the back (dealer special huh). Put about 10k on it then I got 4 brand new BFGs. Got about 13k on them now and they are wearing in perfectly
@@krisramos7453 how much high speed offroading do you do? They don't last long under the conditions the truck was built for, but I reckon the "raptor specific" version saves Ford money and gets better mileage, so there's that at least.
@@T4nkcommander my truck does either beach running (15mph speed limit on most beaches here so I’m not flying) or crawling through woods trails. Also thousands of miles towing an aluminum boat. Other wise it’s a lot of highway
