理想21寸轮毂和20寸的区别

There are indeed some differences between 20-inch wheels and 21-inch wheels. First of all, in terms of size, 20-inch wheels are smaller than 21-inch wheels, which also means that the tire aspect ratio of the 20-inch wheels will be relatively larger. This design makes the 20-inch wheels perform better in terms of practicality and comfort.
The 21-inch wheels, although slightly larger in size, have attracted many car fans with their strong appearance impact and sporty feel. However, the increase in wheel size also brings some negative effects. For example, in order to ensure that the outer diameter of the tire remains unchanged, it is usually necessary to choose a tire with a lower aspect ratio when replacing a large wheel hub. Although this can improve the vehicle's stability and lightness when cornering, the shock absorption performance may be greatly affected, causing small bumps to be significantly transmitted into the car, reducing ride comfort.
In addition, low aspect ratio tires are relatively weak in responding to external impact forces due to their thin sidewalls. This type of tire is more likely to bulge when driving on rough roads, and may even cause a puncture due to encountering sharp objects.
