Why are off-road vehicle tires thick and sports car tires thin?

Why are off-road vehicle tires thicker and sports car tires thinner? Off-road vehicles with thick tire walls are less likely to get blown out when driving on bad roads. Comparatively, sedans have higher requirements for road conditions. Considering stability, comfort and aesthetics, there is no need to use tires with particularly thick tire walls! Let's learn more about this below!

Why are off-road vehicle tires so thick?

Because off-road vehicles will drive on some very extreme roads, and the sharp stones on these roads are relatively sharp. It is easy to puncture the tires. Just think about it, if you have a punctured tire in the wilderness, it is very troublesome to change the tire, and it is very physically demanding. Sports car tires are thin because their driving environment is better and the road surface is flat. In addition, most performance car tires are relatively thin and wide, in order to have better grip.

But it is really something you can only feel with your naked eyes! I can’t capture half of its beauty!! No matter what, just give it a try!

Why are sports car tires thinner?

Sports car tires are relatively thin, which means they have a high aspect ratio. This is also determined by the environment in which the sports car is used and its own properties. The nature of a sports car is that it has the characteristics of fast acceleration, strong grip, good braking, good cornering support and strong stability, which requires the tires to have a high aspect ratio and a large contact area with the ground.

How to judge the thickness of tires

The thickness of the tire actually refers to the aspect ratio of the sidewall. Off-road vehicles pay attention to passability, and use tires with a high aspect ratio (so-called thick) to effectively improve passability on unpaved roads. In particular, the tires used by extreme off-road vehicles not only have a large aspect ratio, but also have rough treads. In addition, off-road vehicles must adapt to various extreme road conditions. For example, when passing through desert areas, it is necessary to reduce tire pressure and increase tire friction. Sports cars, first of all, they are road-going, and secondly, they need to run fast enough. Then it needs to have enough grip, a low enough chassis, higher safety, and finally be able to brake (a sufficiently low aspect ratio with an oversized wheel hub can accommodate oversized brake pads and braking systems). Therefore, the tires equipped on sports cars are all explosion-proof tires with widened tire width and low aspect ratio.

Tires are very important for cars. When consumers buy car products, they must carefully distinguish between wide tires and narrow tires. Wide tires are better for cars in terms of tire material and tread pattern, which makes the car have stronger grip during use. This is why SUVs and off-road vehicles use wide tires.
