Car tires are so dangerous, why not make them solid?

First, solid tires increase unsprung weight. The greater the mass under the suspension, the slower the response of the suspension system to the road change, which has a great influence on the dynamic performance of the vehicle. The earliest rubber tires were solid, but they were uncomfortable to use. As the saying goes, "Shoes weigh one catty, people weigh five catties", and so do tires. Solid tires are definitely heavier than current pneumatic tires, which will consume more oil. Moreover, the comfort of solid tires is not enough, and the sense of bumps is stronger during driving.

Moreover, when the tire runs at high speed, standing waves may appear on the carcass because it is too late to recover its deformation, which may lead to a sharp increase in tire temperature and a puncture. Solid tires are more prone to this phenomenon. When a solid tire is used for testing, tire fragmentation will occur. So solid tires can't run fast, while pneumatic tires can run for a long time at low temperature. After weighing the gains and losses with performance, there is no doubt that human beings have chosen better air tires and given up solid tires. . . .
