What are the pros and cons of large car wheels?
1 Answers
Large wheels have the advantage of improved safety performance; the disadvantage is reduced comfort and shock absorption. Major advantages: The biggest benefit of large wheels is improved safety performance, because large wheels have smaller tire aspect ratios, lower heating rates at high speeds, and smaller pressure changes. Therefore, cars with large wheels, wide tires, and low aspect ratios will have improved safety performance. Additionally, large wheels help enhance off-road capability. Disadvantages of large wheels: Due to the thin sidewalls, tires on large wheels often have weaker resistance to external impacts. They are prone to bulging when driving on rough roads, and sharp objects may even cause blowouts directly. Moreover, almost all large wheels are heavier than small wheels, and thin tires cannot balance this weight, leading to increased unsprung mass, which negatively affects fuel consumption, handling, and comfort. In other words, large wheels significantly reduce the car's shock absorption and comfort.
