The size of the car wheel will have different effects on the car's carrying capacity and cornering performance. The specific use of the size of the wheel, the owner can choose according to the difference between the two.

1. In terms of bearing capacity, the large rim is stronger than the smallrim. In order to save cost, the small wheel rim is usually made of steel, and the large wheelrim is made of aluminum alloy, especially the forging process is better, and the bearing capacity is 5 times that of the ordinary steel wheelrim.

2. Cornering performance. When the wheel is cornering, the large wheel rim can improve the cornering performance of the vehicle. After the wheelrim is modified, the ground contact area of the tire is increased, which can increase the grip, so that the smooth performance of the vehicle in cornering is improved, which is conducive to the safe cornering of the car. The small wheels do not perform as well as the big wheels in cornering performance.

3. In terms of comfort. The larger the tire, the thinner the tire thickness, resulting in poorer isolation from road noise, so there will be more noise in the car. Small tires, to a certain extent, can reduce noise and make driving more comfortable than large tires.

4. The performance of the car. Because of its large size, the big wheel will affect the acceleration and braking of the car. The bigger the tire, the more weight it will take, and the car needs to consume more fuel to be able to support the operation of the big tire. Because of their smaller size, small wheels will use less fuel than large wheels, which can also accelerate faster than large wheels.
