When you choose a car, you don't know if you care about the size of different wheels and tires of different models, and you know that the larger the wheel, the stronger the visual impact of the vehicle, so is the car tire as big as possible and wider as possible? Why are the tires of luxury cars on the market generally large in size and wide tires? If it's true that bigger tires are better, then why can't all family cars be replaced with tires with larger hub sizes? Today, Tutu will discuss this issue with you.
First of all, there is no doubt that the performance of larger wheels must be stronger, as for why do you say that? Because the increase in the size of the wheel hub may not change the overall circumference of the tire, but will increase the radius of the hub and reduce the thickness of the tire wall, it can be understood that the tire wall will be thin if the hub is large, and the tire wall will be thick if the hub is small.
To put it bluntly, if the wheel hub is upgraded from 17 inches to 19 inches, the tires will not become larger, but the larger the size of the wheel, the smaller the flat ratio of the tires, and the section of the tires will increase after the flat ratio is smaller, and the thinner the tire wall will be.
In addition, wider and wider tire sections will also improve the grip of the vehicle when driving, so it is not difficult to see that the wheels with relatively large factory size are equipped on some relatively high-end, relatively strong performance models, which can play a good role in the support capacity of the sidewall and the twisting and slip when cornering, so as to avoid serious roll and understeer when cornering at high speed, and improve the grip of the tires at the same time, which can make the driving more stable and let the power of the car engine get enough play.
So since there are so many benefits to large-size tires, why can't the tires of ordinary family cars also use large-size tires? This is because it needs to be tuned according to the overall level of the car, because the bigger the tires, although the performance can be improved, but it also brings disadvantages.
First of all, the first point is that the thinner the tire wall, the whole vehicle will be stronger after the shock absorption, generally the more high-end models are more well-tuned suspension, with this kind of large-size wheels can still ensure comfort, and for our ordinary family cars, whether it is suspension or chassis is certainly not as good as these high-end models, if the hard tire sidewall is thinner this large-size wheel, the comfort of the whole vehicle will be greatly reduced.
Another point is that the problem of fuel consumption needs to be considered, because the tire section is large and the area in contact with the ground is also large, although the stability is strong, but the fuel consumption of the car will undoubtedly increase accordingly, because the friction surface between the tire and the ground has also become larger.
In addition to increasing fuel consumption, the power of the vehicle will also be affected, generally for high-end models, the power problem does not need to worry, the power is very sufficient, but for our ordinary family car, if the power is only 1.5L displacement, replace this flat and wide tire, the power may become very meaty, but also because the friction resistance is too large, the power is not enough to bring up.
Therefore, the tires matched by different levels of models must be different, of course, this kind of flat and wide large-size wheels are not all benefits even in high-end models, first of all, the biggest disadvantage is that the tires are particularly easy to bulge, that is, because the entire tire sidewall is particularly thin, when encountering some potholes and bumpy sections, the sidewall may give pressure to the wheel hub because of insufficient buffer force, resulting in a bump in the wheel hub or a tire sidewall bulge.
All in all, no one is perfect, and the same is true for cars, what kind of car to buy and what size of wheels to choose, there are good and bad aspects, after all, the pros and cons are inseparable. I don't know how many inches of wheels everyone's car matches? Do you think it's better to have a big wheel or a small one? Feel free to leave a comment to let us know what you think.
