The development status of tires


With the development of tire production technology, the development direction of tires is constantly changing. Electric vehicle tires, safety tires, green tires, low-profile tires, etc. are all development directions that have attracted much attention.

Electric vehicles use batteries, controllers, and electric motors to replace the engines of fuel vehicles. The battery increases the mass of the vehicle itself, and the instantaneous induced torque of the electric motor is larger than that of the engine. Therefore, electric vehicles put forward higher requirements on tire pressure, static friction at starting and rolling resistance coefficient. In addition, the noise of the electric drive system of electric vehicles is lower than that of fuel vehicles, so the tread design of electric vehicle tires needs to reduce the noise caused by road reasons; electric vehicles also have higher requirements for lightweight. Electric vehicle tires are no longer ordinary tires, but intelligent tires, especially in high-performance electric vehicles.
