From 65438 to 0946, Michelin Tire Company of France trial-produced the world's first radial tire. The invention of radial tire is a revolution in tire industry and has become a new direction of automobile tire development.
Extended data:
First, advantages:
1, large grounding area, good adhesion, small tread slip and small unit ground pressure, so it has small rolling resistance and long service life.
2. The tire crown is thick and has a hard belt layer, which is not easy to pierce; Small deformation during driving, which can reduce fuel consumption by 3% ~ 8%.
3. Due to the few layers and thin side walls, it has great radial elasticity, good buffering performance and large bearing capacity.
Second, the use of precautions:
1. tire assembly: radial tires cannot be mixed with other tires on the same vehicle, especially not allowed to be installed on the same axle with other tires.
2. Tire pressure: Radial tires should be inflated according to the specified standards. When its inflation pressure is the same as that of ordinary tires, there will be insufficient inflation.
3. Vehicle toe-in: When the front wheel of an automobile is converted from ordinary tires to radial tires, the toe-in should be reduced accordingly.
