- Today, whilst on the way to get my mother's 2017 Mercedes-Benz C200 Sport Estate cleaned and put some charge in the battery by taking it for a run, I had a problem with a puncture. Due to the lack of spare wheel, I started to have a few issues, which meant recording this emergency video when other content plans went awry.

This happened you in daylight, near people. Imagine had it been in the middle of nowhere at night. The spare wheel is a great concept, should be the norm.
Yes, I think the tyre was totally flat before I even drove off. My mother has a soft gravel drive on a slope, so it's not always the best for seeing if the tyres are OK. Why Mercedes don't give you one as standard is completely ridiculous.
I’ve been driving since 2002 and every car I have ever owned had a spare tyre and I have never had to use it 🤣 hard lines Lloyd
It would be that within a quarter of mile of my first drive in my mother's car in months that this happens, but never mind! I am probably going to get a couple of tyre inflators for our cars now so we can be self-sufficient in that area.
The tyre is only flat at the bottom 🤣. All that mither because of flat tyre how times have changed !!
It definitely had a nasty puncture, sir....
I’ve just had a puncture on my way to a birthday dinner 3 days ago, I have a spare, tools, and I have road assistance as part of my bank account package…
AA took 1.5hrs to arrive which coincided with the end of the dinner, the mechanic was done in 15 mins.
The one thing I WILL pack is gardening or grip gloves because even tho I couldn’t chsnge the wheel in my nice outfit, had I not been dressed up those gloves would be a blessing.
Yes, I changed a wheel on my Volvo the other day (it also has a spare with tools), which was in the rain... You have to know what you are doing, and have to stand on the wheel brace to loosen the nuts in many cases, but we managed it. I understand what you mean about wearing nice clothes and then having to try and change a wheel!
Yes absolutely to have a full size spare wheel and also basic tool kit in the back of the car. Even bolt cutters & battery powered angle grinder, because of those unscrupulous clamping companies that exist.
I do like having spare wheels in both our cars, I must say. They should be standard. Don't like those clamping companies either!
@@lloydvehicleconsulting
That's why we should carry such things in our cars and encourage it. Maybe you can MR Coleman could make a video about basic tools one should carry, to help less educated motorists.
@@paulie-Gualtieri. , that would be an excellent video for Mr Coleman, I think. He has one on coolant and one on the difference between single and dual mass flywheels, but after that essential tools to keep in any car would be absolutely brilliant!
@@lloydvehicleconsulting
Yes I think so especially in general. with newer cars be more reliable people tend, not to carry tools, but there's always those occasions where one can get caught out.
@@paulie-Gualtieri. , that is certainly the impression most people get, although you still need to check on a modern car otherwise it can certainly come and bite you as you least expect it.
Yes a spare wheel in a vehicle is a must, I got a blow out on the A1 near Harrogate a couple of years ago after hitting something on the carriageway, not very nice in the dark with lorries thundering by a few feet away, but I was on my way again in 15 minutes ! Good video highlighting this.
Yes, you are absolutely right! This is why both our cars have spare wheels, even if they are just spacesavers. It is just quicker to do it yourself if you can, isn't it, even if it is not pleasant!
Yes I agree that you should have a spare wheel in your car, it’s a totally stupid idea switching that for that for a tyre pump and tyre goo, which tyre fitting garages absolutely hate.
Thankfully my Rover 216 and Renault Scenic both have a spare wheel each.
But I feel your pain in not having a spare tyre as motorcycles don’t have spare tyres, or even an inflation kit!
I was on my way on my Yamaha 900 to Grimsby from Macclesfield, riding over the Peak District and I had a flat tyre just before Glossop out in the sticks, I had to wait 2 and a half hours in hot sun for the RAC to come and help.
Good vid again Mr Lloyd.
Oh gosh, sir! The tyre inflator was brilliant, it worked and it was easy to use, but it didn't help in my case as the puncture was not a slow one. The can of sealant was not somewhere I was willing to go, and can damage the tyre pressure monitoring system according to Mr Coleman. Glad both of your cars have spare wheels, sir! Waiting for the RAC on the motorbike sounds really quite tedious.
Yes i do like the back up of a spare wheel. I don't care if it robs me of some miles per gallon. I remember having a tyre knifed in Glasgow once and it was nice to be able to change it and be on my way again. No amount of tyre weld was getting that back
Yes, you are right, sir! One of the great things about the Mark IV facelift Seat Toledos sold in this country was they pretty much all came with spare wheels as standard, something I very much appreciated. I didn't really bother even looking for the tyre sealant, sir!
I agree cars need to be equipped with a spare wheel, even if it’s only a space saver.
My present car has a space saver wheel. My previous car only came with the inflator and tyre sealant, which is useless in the event of a blowout.
I know this may sound cynical but I think the reason car manufacturers don’t fit a spare wheel has a lot more to do with cost rather than weight saving and emissions. A wheel,tyre , Jack and wheel brace obviously costs more than inflator and sealant. That adds up to a considerable cost saving overall for manufacturers producing thousands of cars each year.
Yes, the inflator is a useful piece of kit for any car as you don't need to visit a garage to top up tyres, but you should still have a spare wheel, jack and wheel brace as standard.
I agree, it may not just be to do with emissions and fuel economy test, it could well be cost as a tyre inflator is pretty much universal, as is the virtually useless can of sealant!
@@SimonWoodburyForget to answer your question, yes I’ve had a blowout with no spare wheel. This incident happened on a bank holiday weekend. I had to call breakdown service and wait for almost an hour for them to arrive. The recovery service was extremely busy so the breakdown patrol removed the wheel and took it to the nearest tyre depot to have a replacement tyre fitted. This resulted in another wait while the replacement tyre was fitted and I had to pay a premium for the tyre because it was a bank holiday and had no option but to buy the tyre from that supplier.
That’s why I will always ensure I have a spare wheel. As I said my car has a space saver wheel but at least I can fit it and continue my journey, albeit at limited speed and distance.
Also some tyre sealant supplied by car manufacturers in emergency kit is of the type that means the tyre cannot be repaired if the sealant is used. I work in the automotive trade and have had customers express their frustration at having to replace an almost new tyre that had a puncture because it could not be repaired after using the tyre sealant supplied.
@@SimonWoodburyForget I have had more than one blowout. My work involves me having to drive so consequently I cover high mileage each year.
I mentioned that particular blowout simply because it was a bank holiday, my family were with me and I did not have a spare in that car.
Also this incident occurred 80 miles from my home, which obviously meant I could not call on a friend to help out or my usual tyre supplier.
Yes I only waited approximately one for the breakdown service to arrive but I then to wait again whilst the breakdown technician took the wheel to the tyre depot to have a replacement fitted. This took about another hour.
I opted to let the breakdown service take the wheel and have a new tyre fitted by a local tyre supplier to avoid having to have the car recovered home.
I was told by the breakdown technician that waiting time for the recovery truck would be in the region of 3 hours. As my wife and family were with me I did not want to be waiting at the side of the road for that length of time.
I’m quite capable of changing a wheel on a car.
My point is that if I’d had a spare I could have changed the wheel and been on my way again easily within half an hour.
Once home I could visit my local tyre depot and either wait for them to fit a replacement tyre or leave the wheel with them and collect it later.
If you have a blowout or puncture and have a spare wheel then generally you can continue your journey in a relatively short time once you’ve changed the wheel.
The only exception in my case would be if I was on a motorway. For reasons of safety in that situation I would call breakdown service and let them fit the spare.
If you’re happy just having just the tyre repair kit in your vehicle then that’s your prerogative.
Personally I would opt to always carry a spare, simply because in the event of a blowout the tyre repair kit is useless. Yes I’m aware that the odds of having blowout are rare. However having been in that situation more than once I would rather have a spare and be back on the road in minutes rather than having to wait hours for recovery or a mobile tyre fitter.
@@SimonWoodburyForget it’s blatantly obvious that we’re never going to agree on this subject. However I do agree that blowouts are extremely rare on good tyres.
An acquaintance of mine recently hit a pothole on a rural road. As a result the tyre suffered a split in the sidewall. He was driving a hire van at the time which was equipped with a spare. Fortunately the only damage was to the tyre which he had to pay for.
He owns an EV and was grateful that he wasn’t driving that at the time. Clearly a spare in an EV is not practical due extra weight and resulting affect it would have on range. In the case of his car the charging cable is stored under the floor, so there’s no space for a spare wheel.
If in the future I buy an EV then clearly I will have to accept that a spare isn’t practical.
As I said it just my personal preference to have a spare going on past experience.
I have never been unfortunate enough to get a puncture without a spare wheel but my Wife's car and my Daughter's car only have repair kits so the day will come eventually. As you have shown us all, it may be a case of sealant applied and tyre inflated or it may be stay put until you get rescued as there is no guarantee that the tyre will be repairable.
Yes, it was much better to try with the inflator (which would be useful in any car) to see if it was a slow or a fast puncture and then call the breakdown service rather than fiddling with the can of tyre sealant. I still would have preferred to have a jack, a spare wheel and a wheel brace, though!
@@lloydvehicleconsulting I used to do truck and van bulk loads at all hours. Up to 3.5 tonnes wheel changes are the same as normal cars. Even big SUVs have alloy wheels and simple to use winches and cables to lower and raise spares. Just like a Ford Transit van. I have had to change them many times and I am just a small chap. 20/25 minutes and away. Ask them to try selling a commercial vehicle with a tyre repair kit.
@@seancooke4127 , Mr Coleman is the king of changing tyres, as he does it on trucks, but I have to say that I wouldn't want to do it unless I absolutely had to. I did it for a friend back in around 2014, and I can't say that I particularly enjoyed it, but it was a lot quicker to deal with it than not having a spare.
My friend had a puncture in his new Peugeot. No spare in that, only the tyre inflator gunk. He had to take it back to the dealership to get a new tyre as the dealer hadn't put in a locking wheel nut key.
I think we can all agree the tyre sealant doesn't really do a lot to help. I did check that the locking wheelnut key was in the car. Praise the Lord it was!
I believe a spare wheel is a must. So far I've only bought cars with spare wheels. I guess it's only a matter of time...... However, I think things are getting worse Sir. I've read that Kia says the electric Nero can't even be jacked up because it will bend the frame of the car due to the weight of the batteries. Buyer beware I guess. Another interesting video Joseph. Thank you.
Oh sir! Yes, much better to have things like a conventional handbrake and a normal spare wheel, isn't it? Lots of electric cars don't have spare wheels, so I suppose that is the way things are going, sadly.
@@lloydvehicleconsulting Spot on Sir. When my 2016 i10 went for a service and MOT this month on 4th March the main dealer lent me a top of the range all electric Kona. It was an interesting drive, well engineered, but I didn't like it with electronic everything. It was rather like driving a computer on wheels. Of course I asked the price of the vehicle, but at over £40,000, it can't be for me. Totally unaffordable.
@@martinwalker3088 , I am not a massive fan of the Kona. I have driven other electric cars, and would probably rather spend a bit less money to get one of those. The MG5 EV is much simpler and much cheaper and doesn't look quite as controversial either, for example. Not everyone needs or wants an electric car at present, however,
Absolutely. Tyre sealant really not best for the 3am blowout on the M42. Always taken a full size spare on long journeys. Piece of mind. No TPMS warning is a safeguard (for me, personally).
That's right, the tyre sealant has such a bad reputation that I didn't even bother trying to find it properly. I think if my mother changes her car again, I would like to find one with a spare!
Being in the Merc on the back of the flatbed looked like fun! 😀
Your mum has history of excellent cars (from memory) , more interesting than my parents. The Merc looks really good.
Agree re: the spare wheel issue. Like electric parking brakes, this new trend seem to be a bit backwards. My Almera has 16" alloys but the spare is a 15" which is more than adequate.
Yes, it was fun being in the back, sir! Absurd, but fun. My mother had two E90/91 BMW 3 Series before this Mercedes, and then she had an E34 5 Series before that. I don't like electric handbrakes, sir, or missing spare wheels, and this car suffers from both issues, sadly.
The lack of a spare wheel is because of the emission regulations. To get the C02 levels as low as possible they remove the spare wheel which reduces the weight of the car when testing. In theory if the manufacturer offers a spare wheel as an option if you buy the car new and have the spare wheel fitted then the car needs reclassifying. Instead of having to test cars both with and without spare wheels they just delete the wheel. The same applies to wheel and tyre size. When I bought my last car by optioning 19-inch wheels the car tax rate went up. Instead, I bought it with 17-inch wheels and swapped them for the 19-inch wheels on the dealers’ demonstrator.
Yes, I have been following these emissions regulations for a while now. Manufacturers are starting to get rid of a lot of options as WLTP regulations stipulate that every version of a car needs to be tested, including the options available, so many now just have option packs or merely trim levels (like Kia, MG and others). It's not exactly a development that I welcome taking what should be standard out of the car, but there has to be a reason for everything.
One thing I like about the R50/56 Minis is run flat tyres ( unless you have 15” ). However some owners change them for standard ones as I found out when the valve pin snapped. And I had to call the breakdown and be trucked to the tyre place.
In theory I know how to change a wheel but I have not done it in about 25 years. I think it was on my Volvo 360. Also these days the nuts are done up so tightly you cannot get them undone by hand.
One disadvantage with run flats is that if you do get a puncture they are much harder to repair than standard ones. If it is anywhere near the sidewall it’s a write off.
Ah yes, sir! I remember the run flat tyres on Minis and BMWs from the 2000s. My mother had two E90/91 Tourings which were supposed to have run flat tyres, and certainly the second one had standard ones on it by the time that she owned it.
I changed a wheel last in around 2013, I think. It was on a Seat Arosa, and I had to stand on the wheel brace to undo the wheel nuts. Oh dear, the valve pin snapping doesn't sound like fun!
That’s crazy, chauffeured Mercedes drive with no driver but better height 😆 a spare tyre is a good thing, saying that 2 are better or even 4, but that’s not really feasible. Many years ago Annabelle and I were travelling with mum on a dual carriageway near Newcastle in a Clio when people frantically started waving, it was already to late, we hit a bit of pallet with popped two offside tyres. When we came to a halt there were around 10 or so cars, which had done the same. We then witnessed more do the same, we tried to warn, recovery arrived and relayed us home. *B
Yes, sir! Chauffeur driven Mercedes, but no one in the driving seat. Fantastic... That sounds very unpleasant about the double puncture in the Clio! Let us hope that we don't have to change any more tyres on the side of the road again.
I won't drive a car without a spare wheel. On my last couple of new cars it was an optional extra and I specified it. Unfortunately I've only got one of those small space saver spares on my main car but it's better than nothing. My 16 year old Corsa has got a full-size spare that came as standard. if I remember rightly, my 2008 Hyundai i30 came with a full size spare as standard.
A few months ago I went to a local shop in my Corsa and when I got home I could hear loud hissing. One of my rear tyres went completely flat in about 5 mins. A stanley knife blade had sliced into the rubber. I put the spare on the next day and could drive as normal until I took the punctured tyre in to a tyre place. unfortunately the puncture was so bad that it couldn't be repaired and I needed a new tyre but I was barely inconvenienced at all. I wanted a new tyre so I still had a spare for future use.
I've never used one of those cans of gunk they give you on new cars but I've heard they aren't very effective and can make a repairable tyre, unrepairable. I wish car manufacturers would stop turning cars into computers on wheels and provide something simple basic and useful like a spare wheel instead.
Yes, I deliberately did not look for the can of tyre sealant as I heard really bad things about it. I am glad that we did not go there this time... Both our cars have spare wheels, and I got one for the Rover myself as it did not come with one (someone had stolen it, I think). My mother's car cost over £30,000, and I think it is ridiculous that there is no spare as standard.
I love your show Joseph. Pete
Thanks very much indeed, Pete! Glad you enjoyed the video.
It's always good to have a spare, even if the manufacturer doesn't provide one or have run flat tyres. But nothing will save you if you have a side wall kerb damage. So a spare wheel is a must.
That's right, both of our cars have spare tyres, my mother's one does not. I am hoping that it will not be a problem again, but I will look into the price of spare C Class wheels for her.
@@lloydvehicleconsulting I need to find one for the X1 as that is our family car, but it's sheer good luck I never had to change wheels. But I had slow punctures and having the air compressor has helped me to pump up and take it to the nearest tyre place to sort it for me.
@@allwyndsouza1962 , yes, I had the compressor to hand, but unfortunately the tyre was too far gone by the time that I came to use it. Useful to have one of those in any car, really. I have had a slow puncture before, fortunately Mr Coleman sorted it out for me in the instance.
Yes slow punctures have a nasty tendency to turn into a fast puncture and it's terrible scraping your way to a tyre retailer possibly damaging an alloy
I didn't enjoy the scraping noise, sir. Fortunately, the rim wasn't damaged as I hardly drove it anywhere...
From experience, tyre sealants either work like a miracle or they don't LOL, but at worst will usually get you a mile or so to a tyre centre, so for what they cost well worth having in a car like that. I would be very uneasy driving a car without a spare..even a 'space saver' is better than nothing..sometimes you can pick up space savers cheap on Ebay where the owner has modified the wheels etc.
I wasn't keen to even try the can of tyre sealant, sir, and I am glad I didn't. Both our cars have spare tyres and I bought one on Ebay for the Rover, but I think now I may as well get a couple of tyre inflators so I don't have to do it at Sainsbury's every time...
got to have one
It should have been standard, shouldn't it?
when in the market for a car you want it to be a car you will enjoy all the time and not a car that has simply has a spare for the rare occasion a flat occurs , i think they cut out the spare to save on weight and cost. If all things were equal I would prefer to buy a car with a full size spare but things like performance and economy are more important
Yes, they do tend to cut out the spare tyre for weight and cost reasons. I do like having a full size spare, our previous car actually had one. Thank you for watching!
I feel your pain, at least you were near your mothers. I got a rover 25 space saver for the wife’s Honda, the 1987 polo & 1992 mx5 have spare wheels as standard, but the Mazda 6 only has the tyre weld stuff. My old 1980s & 1990s toyotas even had full size matching alloy spare wheels.
My 1993 Camry, 1999 V70 and 2006 V70 all had space savers but that is no disadvantage because you can complete your journey on the space saver, at 50 mph, or change the wheel and go to the tyre shop and have the flat tyre repaired or replaced. Providing you are within opening hours of course. Tyres don't just deflate between 9 o'clock and 5.
@@seancooke4127 yes a space saver is a god send, I wish I had one for the Mazda, but no room thanks to the adblue tank
Yes, I probably drove less than 1/4 mile on it. It was only when I got away from my mother's house that I noticed there was a problem, especially as the tyre pressure monitoring started going off. Both our Rover and SsangYong have spare wheels in case we need them. My previous Rover 45 had a full size alloy spare!
@@lloydvehicleconsulting I am not a fan of Tyre pressure monitors, but it gave you forewarning of the problem there, so useful in that respect
@@badbooks476 , in this respect it was really useful as it confirmed my suspicions of why the car wasn't driving correctly and also showed me as the tyre deflated after I had taken the compressor out.
I would not own a car that didn’t have a spare wheel , I have needed it on several occasions over the years. Could you not have got a mobile tyre fitting service to come to you ?
I could have called a mobile tyre fitting service, but I know the tyre bay in question and my family have been using them for about 20 years, so no hesitation, really.
Space saver whilst a bit of a pain, would be a far better option. You pay a lot of money for a new set of wheels these days. Ok not that many buy them outright, but still a space saver at the very least should be compulsory item. In countries bigger than Blighty, like Australia, where the nearest tyre shop could be hours away in the outback could endanger ones life! It is a horrible trend that needs to stop.
Yes, I think every single car on the market should have a spare wheel, wheel brace and jack as standard. Having a tyre inflator too would be a nice bonus, as they are useful in any car. The breakdown service came within half an hour and it was just 15 minutes to the fast fit centre which my family and I have been using for years, which sorted it all out. The can of sealant would be pretty useless in Australia, wouldn't it?
Glad they got you sorted, but what an inconvenience. With a space saver, 15 mins you could of been back on the road again.
@@adamtoms2726 , yes sir! I have changed a tyre by the side of a road before when a friend's Seat Arosa developed a puncture. It required a bit of effort, but it was OK.
I think you answered your own question:- YES we do need a spare tire! Is it legal to travel in the car on a flat bed?
It is perfectly legal to travel in a car on the back of the truck and Mr Coleman confirmed it too!
@@lloydvehicleconsulting I'll take your word, but once about 20 years ago when i was a lot younger and out with my friends we broke down and a flat bed came but only had 2 seats and there were 3 of us and we suggested that one of us could sit in the car on the flatbed but the patrol man said NO its illegal..............one friend had to catch a £30 cab!!
@@trabali5168 , they must have changed the law since then, either way nothing was questioned. It was a very, very strange experience and weirdly enjoyable as well, although I would have preferred to go in the cab, of course.
Guarantee if you carry a spare you never need one, I can’t recall ever getting a roadside puncture in 35 years of driving but woken up to one etc, I guess it’s a risk balance....
It is, sir, and I was able to drive on it for a short distance. Haven't had a tyre quite as flat as this before, at least my mother wasn't driving!
@@lloydvehicleconsulting you jinxed me! I had a flat in the Land Rover tonight 😂
@@AgathaAndAnything , oh sir! I am ever so sorry to hear that. I hope that it wasn't too awful!
If I bought a car without a spare wheel, think I would buy a wheel to put in the boot, even off a scrap car for example. Peace of mind if nothing else
That's what I did with our Rover 45 V6 has someone had stolen the spare before we bought it!
Always need a SPARE TIRE…or Drive in METAL Road…or other wise Tie your Shoes on it,maybe solve the problem….
A comment from a parallel universe?
A British Agent.. Dear me! i’m terrible sorry. i ment British consultant in a very good looking German vehicle! But still a dark green Rover with Beige leather interior fits you more sir.

Problem: My 2019 KIA Forte I bought new did not come with a spare tire.
Solution: $315.00USD KIA OEM spare tire kit. Comes complete with wrench and jack.
My KIA came with no spare tire but had a can of sealant, a 12VDC compressor. By the way the sealant expires May 2024 which is 5 years after the car was made.
Good luck fixing a tire on the side of the road. At night. No light. With a large puncture or hole in the sidewall than can’t be fixed.
Don’t be a dumb ass. Get a spare tire kit from the manufacturer and, if they don’t have one, get a serviceable tire from the junk yard, a tire wrench, and jack and hope you’ll never need to use it. I know, I know, just make it fit and take less luggage. Hope you never need to use it.
How’s you wife going to react when you get a flat tire at night with you, the wife, and the kid in the car? Thinking about that should be enough to scare you into a spare.
Fortunately, this car has now been sold, and all the others of them have proper spare wheels.
Once again if you read the manual you also receibed a botle of anti puncture foom that will cover 99,9% off tyre problems. only idiots that don't know how to read are not covred...
Do forgive me, especially as I don't believe that we have had any correspondence before, but it seems like you are implying that someone you have never met before on the Internet is definitely an idiot without really endeavouring to put yourself in this unfortunate and unexpected situation that I found myself 18 months ago, and that you would definitely not have made any mistakes when put in the same spontaneous scenario. If so, then may I remind you that people who make UA-cam videos are at a definite disadvantage when we have no idea who someone is if they are watching or commenting on a video, whereas the person who is watching knows perfectly well who we are.
@@lloydvehicleconsulting I don't know who you are, what I do know is that anyone who makes videos for UA-cam should try to give their opinion and not turn their misfortune and inability to deal with a simple problem into a judgment of a system that is brilliant.
otherwise let's see,
The tire repair kit is: lighter, less bulky, cheaper, cleaner, less work, faster, has tire pressure monitor and warning, solves multiple punctures, answers 99.9% of problems and we have to read the manual.
The spare tyre: it is heavier, removes volume from the luggage compartment, takes longer, more expensive, dirtier, tiring, does not solve 100% of the problems, in the case of multiple punctures it does not solve the problem and any jack knows how to use it.
