Langsam wird's Zeit: 8 Todsünden beim Winterreifen-Wechsel - Bloch erklärt #198 | auto motor sport
Deadly sins when switching to winter tires, there are some we need to talk about who probably don't even change tires out of laziness or stinginess, but just stick with summer tires, yes here on our new VW id.4 Longer lasting GTX. there are also summer tires, on top of that, the patients know this, because they are there again and again in winter and at the latest when winter comes somewhere and there is a total lockdown and then in many cases you know what is behind it, but there is also a legal situation, we have to go through it there is a situational obligation to have winter tires in Germany, that means we do not have a general obligation to have winter tires I cannot stop the police in December when it is 15 degrees Celsius outside and the road is dry and I can say boy you need a pair of winter tires but not as soon as there is frozen water on the If the road is snowy or slippery then you have to put on winter tires and we can also look at the sanctions, it basically starts with the police stopping you because come here there is a little snow on the street and you continue driving with summer tires with 60 euros and a point if you obstruct It's the traffic, you don't end up in a bad mood from the people behind you, but the police condemn you to 80 euros and one point and if you later have an accident because you have summer tires instead of winter or all year tires, then it won't be much more expensive, you think 120 euros and The problem is still a point, but now the insurance company gets into the whole thing because they look very closely at whether that could be prevented, if it was a sudden onset of winter outside, it's only 18 degrees outside when suddenly there on the street it starts to snow you couldn't count on it then the insurance company will have no recourse but if it has been snowing on the street for a week and you are still driving on summer tires then it may happen that you lose your insurance coverage and that will be very, very expensive and when can I leave the summer tires on if you know under all circumstances that you will soon have even the slightest hint of the onset of winter and that you will have to this Leave the car then it really stays there you don't have to trust it either so not again in an emergency ah come on that doesn't matter now I have to drive no if you know in winter and the corresponding winter conditions leave the car then you can leave the summer tires because in dry conditions and for the most part also in the wet, summer tires are better up to a point, even in relatively low temperatures, so relatively cold temperatures have to be limited a bit, there is the so-called rule of seven degrees that you supposedly have.
Winter tires work better than summer tires, that's wrong, that's nu. One rule of thumb because even at such temperatures summer tires still work great, but as soon as you get to sub-zero temperatures summer tires get so hard that winter tires or all-weather tires work better, so that you only put summer tires if you really know the car will stall if things get complicated deciding whether to use winter or all-weather tires pay no attention to the car and the area of application used to be rare in Germany keep buying tires winter there was now a very small market for all-weather tires, but let's take a look at North America, where the jungle is being cleared.
He mainly bought all-weather tires and was less specialized in winter tires and you can already tell that man this area of application. this climate zone this landscape and whether it is winter or not that plays a role and before going into a little more detail a quick recap on the differences between a pure winter tire and an all weather tire the most important point is that they are both winter tires your winter tire is defined by the alpine symbol if i can't find it right away i have shown it many times but it doesn't matter maybe i can show it as a section view number so it defines they are both winter tires winter, but an all-season tire is designed for a wider temperature range in terms of its rubber compound and profile, which means it has a rubber compound that is a compromise for warmer and colder temperatures, while that a winter tire is primarily optimized for colder temperatures and on average the rubber compound is a bit softer and the profile of a winter tire or have more slats here.
I can see the cleats have a little thicker tread than an all weather tire that also has cleats but it's not as pronounced as a winter tire should first all is enough and now you just have to look where I live because I live in an area where winter is very unlikely right now I'm in Düsseldorf that's someone the onset of winter is really very unlikely mountains there's not much back there the Lower Rhine begins it's really flat as lightning the probability is also lower That what goes on there and that's why an all-weather tire is a sensible choice purely from the area of application, especially since all-weather tires have improved significantly in recent years, especially this decade.
If you had asked me 5 years ago if I should buy all weather tires I probably would have said no let's do it winter tires are better all weather tires can't do one like the other but we can take a look to an electric car super test of mine the Volvo C40 was that and it had a Mischler Cross all weather tire and there it braked beautifully in dry conditions there I am with the car or did the man brake it first look at the brakes you can see the car goes wonderfully towards the irons, then it's relatively short and I look at the measuring device and there are 34.5 meters again for an all-weather tire that blew my mind.
I have never experienced an all-weather tire this good under braking and have rarely seen tires summer they worked better under braking than this crazy tire really well what they couldn't do before he did wonderfully he drove well so d Also good rolling resistance this is a tire that I can recommend, although not only specifically with clear but there are also very good tires from Goody and others that I can simply recommend if the probability is very small that it is snowing or you are going on vacation to skiing or something like that and you only have one tire that you can drive safely on in the winter, but they certainly also have their limitations in very wintery conditions, so if there's a lot of snow, they're worse than winter tires if I'm going on skiing holidays or if I live in the foothills of the Alps or because of the Alps or somewhere else that I know of, even here in the Sauerland there is very likely to be snow, then I have to decide on winter tires and then also have to look at the car, how do I move? the car so if I have a small car that's not that incredibly dynamic then I can do it easier with an all weather tire than if I now have a big heavy SUV or a very responsive car with which sometimes I also drive correspondingly regions, so I would rather go to a specialist for a pure winter tire than an all-weather tire and because that's a bit complex, the tire manufacturers have also put online help for this, I'm just showing you l One helpful example is a Goodyear tire consultant who simply asks what kind of car you have, where you drive and all the trimmings and at the end gives you a recommendation on whether you should use winter or all-weather tires because I'm telling you honestly.
Now I can spontaneously without knowing from the car trips where you live not to say if one or the other is better for you when deciding what kind of tire to take for winter except for basic winter suitability just to pay attention to dry performance that can be quite dangerous and we have to get hold of test magazines and our own noses because we focus on dry behavior in the usual tests, not in the special tire tests but in the usual car tests, which is braking on a dry road from 100 to 130 km/h accelerate on a dry road that is completely dry and we only test in the rarest cases Again special properties in the wet of which we always do eg my colleague Timo Fleck current car test
sports, he does the tests there and they look very closely at how it works on snow in dry conditions and in wet conditions and there are big differences in Besides sleeping, the dry works great in the wet with certain drawbacks in terms of cornering force and braking distances there is another all weather tire you should use for example all weather tires that are noticeably better in the wet than the mixer is a little worse in the dry So take a close look at what's important to you and if I'm honest, wet is actually the critical situation, we know it on all country roads and you misjudged a bit on the dry bend I maybe can I catch it somehow if it's wet, yes I can, which ended pretty fatally and by the way, I was in the test of the
auto, we can also show the brochure again briefly, what I mean exactly, there was also a BRIDGESTONE summer tire as a reference tire and it has accumulated by far the highest turning forces in the wet, so you will notice that a tire summer can do a lot more in the wet, funnily enough, but it wasn't necessarily better in terms of handling than the Goodyear now, yes, and on the other hand not much worse than humans, of course, it's important to me here, especially before buy the tire look at the competent test reports look at how the wet properties of the tires look because they are very very important for normal driving now i have been talking all the time about wet and dry performance there is another very important point when differentiating between the different types of tires that is rolling resistance and there is the basic statement that a summer tire has a better resistance to the rolling has better rolling resistance as a weather and all weather tire than a winter tire which simply has to do with the rubber compound because the softer the rubber compound the more it can work on itself and the more the more it works the better the more energy I put into it rather than locomotion Winter tires at warmer temperatures when soft yes the rubber compound works there instead of it's just a propulsion to implement you can't say that overall but today i can just say it's very important to pay attention to the tire label what that means let's also clarify an all weather or all season tire buy to save money yes saving a lot sounds logical at the beginning because you don't have to go to the workshop to change the tire the visit to the workshop costs money you don't have to look for different types of tires winter tires summer but as a tire you can drive through katak, that's a must they cost less money yes, but there are some things to pay attention to, which then cost money in the end, on the one hand, wear and tear because an all-weather tire, by the way, it is a winter tire on a weather resistant tire it is a compromise tire also in terms of its rubber compound it will wear significantly more in the summer than a summer tire with its harder rubber compound it has a harder time in winter than a specialist winter tire and throughout the year it will degrade more quickly in terms of its profile than a specialist tire which can lead to you in practice just needing more tires than if you were using specialist tyres, ok no you have to do it take them to the workshop and change them there that is an argument definitely there you can save a few euros and I say it very clearly so I have to be yes that is new our new longer one here and now we have to switch from summer to winter tires and now i know i've already done it with the car it's hell vw didn't come up with the car with such an easy rim design to change i have to be happy with everyone so they can do it quickly the radar that's really difficult and then you don't know where to start either, it's definitely slave labor and you don't want to do it either, and then you'll be happy if he doesn't have to change tires but if the all- The tires for weather they stay put but that's the point - an electric car that has two problems with straight-ahead all-weather tires, it's relatively heavy, which increases the load on the tires, and it has a little power, especially torque, and that's it is also noticeable in the profile and that ensures that these all-weather tires are not only for electric cars but also for powerful and high-traction cars in principle wear out a lot and if l Then you add it all up, then you're there worse and then there's thefact that the purchase price of an all-weather tire is higher than a summer tire and often the same size or higher than a winter tire, so all in all you shouldn't expect save money with an all-weather pneumatic tire, but there are other reasons for laziness, for exampleWhen changing a wheel, do not pay attention to changing the axle, which is logically completely irrelevant with a new tire that has not yet seen an axle, for which doesn't matter at first, but if the tire has already seen the wheel for a season then you should swap axle for axle to get an even wear pattern if the winter tires belonged to the left front last season, to the rear left next season i could still discuss which is the important axle now where the better the tire i've already done that in other videos basically the best tire shouldn't matter if the wheel Either front or rear it is driven to the rear axle because that is the track for an axle which is the axle that skids in the wet which makes it particularly difficult to get the car back on grip which is not to say the front axle isn't also important, whether you have brakes, taxes or the like, but the rear axle is still a bit more critical and when acceleration plays a big role, especially after a scratch on the front-wheel drive or four-wheel drive, the axle striker also plays an important role.Accelerating is not relevant for safety, so it is important that you pay attention to the ax change and then you should look at it Look at the profile, do not change it back and forth for years, the profile is every smaller and smaller and that doesn't matter at all, because yes, there is a legal minimum tread depth. 1.6mm in Germany but it's too low for the tire to still work properly have a lot more tread depth on winter tires and if on a trip to Austria and it says I'm from Germany winter tires with a 1.6mm tread depth are completely sufficient, so the Austrian police officer says we'll take a closer look at 4mm, that's what we need here So there could be a real problem because in Austria a tread depth less than 4mm it doesn't matter if it's winter tires or not the tire is no longer considered a winter tire and I must say why am I right not to pay attention to the age of the tire when changing tires that's hard at first , you bought expensive winter tires for so many years and the profile remains the same ok we'll take a quick look at it if you then also look at how old they are then you have to change ar the tire in the end, that's expensive again, so you hold it back a bit, but tires like those also have an aging effect.
I find calendar aging regardless of whether it is driven or not. UV radiation for example causes a tire to age very quickly, especially if you live in southern regions where the tire gets a lot of UV radiation then the air ages faster or the air also contains ozone this ensures the tire ages faster , which is also a question of storage of the tire ends the reasonable conditions that it lasts a long time and, however, there comes a time when it is no longer so fit and now that just as a little side information, there is an interesting one, I would almost say when a tire is still new so to me a tire is new as long as it's not more than two years old the Federal Tire Industry Association says well we say a tire is new if it's stored properly for up to three years up to five years at least you can still see it as new but no more than sell factory new i'll just let it be the fact that after ten years tops you should think in changing your tires, it doesn't matter what the tread looks like, and with winter tires it's even a little more critical, so you have to think about it after eight years because then really here the tread hardens and already it doesn't work well on ice and snow and that's dangerous, but where?
So I know how old a tire is. I lost the bill. I have no idea. I bought the thing because I bought a used one. I don't know. There is a number here. They are in a box and it says it all. produced here with this tire is 48 21 so it was produced in week 48 of 2021 ie this tire here is about a year old everything is ok profile looks good too can still be good for a few years even with tires winter tires only use extra wide versions I can understand that from a psychological point of view of course there are 275 winter tires here they look a bit more impressive than two 35s which makes something look
sportier and they work too in summer.
We have definitely proven better than wide tires again, that's why in several videos I have also explained that wide tires brake better and better Accelerating in most cases has a better distribution of pressure on the profile that barely touches the road I have improved the conditions again in terms of macro and micro grip called van der Wahlskraft these are really molecular forces of attraction that just as a little digression if he if you look at each other they look at a gecko when a gecko climbs the walls here she always asks how it does how can yours stick to the wall so basically it's kind of like the tire here because a gecko doesn't have suction cups and there's not any goo on their feet but those are Van der Wahlkrafts so really the molecular forces of attraction work there and I can also remove a number such that a gecko can hold up to 40 n when crawling like this 40 newto n numbers to remember a newton is almost 100 grams and the gecko itself only weighs a few grams and then you also know why it is so when d can walk on the ceiling and even if you have a verse you can hardly get rid of it and that doesn't it's so far from the friction of a tire but why isn't a winter tire better if it's wider because wider winter tires have shown this in various tests Snow works worse they don't build much by executives don't they can accelerate so well if you're watching the World Rally Championship and they drive on snow then they don't drive on oversized tires but the tires are actually relatively narrow always aside from the fact that they can also drive with the appropriate studs but it doesn't drive on oversized tires big size meaning slightly narrower tires are the best tires here, especially since they also have better comfort and also better measurement behavior yes I can understand if you want wide tires but maybe not narrower dimension if you think about it in winter to go when you buy tires don't look at the tire label we show there are many numbers and letters on them and a lot of colors and you don't really know how to orient yourself we'll clear it up but now you're skeptical because you know exactly that this tire label has been affixed by the manufacturer and you can trust it just as much as the consumption data from wltp or nafz you have to correct them accordingly or put something on them so that you have the true values, but you can rely a lot on the tire label, that's important, pay attention to that too, then there are four points that are relevant, we start with the first point which is efficiency of fuel or rolling resistance, that is, how much resistance the tire generates simply by rolling, of course, in optimum pressure conditions. ion on the tire, you must not forget that and it is classified from A to E, however, it means that the tire is particularly fuel efficient, so with particularly low rolling resistance and, anyway, it means that the tire is not as efficient and especially winter or all-weather tires are more likely to be in the mid to low range, which are on average higher in terms of rolling resistance than a typical summer tire , which does not necessarily mean that summer tires are always better, but in the
sport tests it can be verified over and over again, for example
auto aktuell already takes summer tires as a reference and they were worse in terms of rolling resistance than usual all-weather tires, so you have to look closely and the tire label also very often corresponds to our test results It's in these areas, so it's not bad, but if I have a particularly low rolling resistance tire, you notice that in testing, then it always has problems in other places, especially when braking, it's not just dry braking, especially braking in the wet then we have that at the next point on the tire the i Solo is wet and these values are also determined through braking so how fast the tire lifts in the wet and there are also A to E , that means with an A graded tire then there's Vanessa very fast and e there he's not that fast and he should actually refrain from doing it, to be honest you have to use mid range or higher and then there's a spec db for the volume on the bottom it's rated a to c because the spread isn't that great and that just tells you how strong the tire is when it rolls and that's very important especially on the highway because it's one One of the most overbearing noises for a car there, the rolling noise of the trucks you know when it drives by and they're doing it right.
Noise and that's why it's an important point and also a good indication of whether you have a little more or less noise. Tire comfort and then there's the Wi point. Intermediate Tires or Not If you want to buy winter tires and you see a tire label and there is no winter tire symbol on it, what do you do? Won't buy the rim because it could be winter tyres, those were the deadly sins when changing tyres, a lot of info though, but I've probably taken it out a bit as well if the Grand Final is still to go and the car is still on summer tyres, so there's to put on winter tires now i got the guns ready here air screwdriver That will make my life a little easier, but not really easy.
These are very heavy tires here, 21-inch summer tires, yes, I think our esteemed colleague Menzel always complains that the big tires here are very heavy and not fun, in principle. , he can also say that as a side note, he really does think twice, but he's always so big. Buying wheels sometimes even with smaller dimensions than 19 inches or because many times they work better in terms of comfort and do not cause so much trouble when changing tires there are 19-inch wheels for winter tires everything is already mounted I have to do it right now I can't delay it any longer I can also whine about it a bit like it's soon I'll swear that's why we turned off the camera and what are you doing look at that video you're still bango like that but stick with the summer tires we're in that. again now ok alex again so just so you know that's a tire that's a rim that's a wheel well did you realize you can keep going?
