Are car tires really flatter the better?

Automobile tires have always been the darling of the modification industry. The tires should be changed before the car is changed. The new car should be replaced with a set of large wheels and flat tires. But are car tires really flatter the better?
Automobile tires, whether modified or modified, have a parameter-aspect ratio, which is the ratio of tire height H to width W; the lower the tire height, the wider the width, the smaller the aspect ratio; conversely, the narrower the tire width , The higher the height, the greater the aspect ratio.

The aspect ratio is clearly displayed on the tire. For example, 185/60 R15, 185 is the tire width, and 60 is the tire aspect ratio.

What are the effects of aspect ratio on tires?

The tires with low profile ratio are low in height, wide tires, obvious road feeling, strong handling, strong high-speed stability; but poor comfort, tire noise is large, because the tires are thin, so pick the road conditions, once you encounter a pit on the road, the chance of a tire blowout Oversized.

In addition, tires with small flatness ratios are more visually impactful and show higher grades, so the flatness ratios of luxury cars and super sports cars are relatively small.

The tires with large flatness ratios have poor road feeling on the road because of the "thickness" of the tires, but they have a large deformable range, good cushioning, good comfort, and strong load-bearing capacity. Therefore, off-road vehicles with relatively large load-bearing capacity usually use flat Larger tires.


In general, tires with low flatness ratio are good-looking, have obvious road feel and good handling, but will sacrifice comfort, road noise is high, and bad road conditions will cause tire punctures and wheel hub deformation; while tires with high flatness ratio, It does not pull the wind, has no sense of road, and has general control, but it has good flexibility and comfort. The road noise is relatively low, and it is suitable for bad roads.The copyright belongs to the author www.jihoowheels.com .
