How to distinguish car tires Car tires are roughly divided into radial tires and slanted tires. The cords of the oblique tires are arranged in a crossed line, hence the name. The carcass forms the basic skeleton of the tire, and the softness from the tread to the sidewall is consistent. Although the noise of the slant tires is small, the tread is soft and the ride is good at low speed, and the price is cheap, but its comprehensive performance is not as good as that of radial tires. Automobile manufacturers are developing new cars with radial tires. Continuous improvement, slash tires will be basically eliminated. The ply of the radial tire is equivalent to the basic skeleton of the tire and is arranged in the same direction as the tire meridian section. Since the tire is subjected to a large tangential force during driving, in order to ensure the stability of the cord, there are several layers High strength, easy to stretch the material made of the belt (also known as hoop tight layer), the cord direction and the meridian section was a larger angle (70-75 degrees), the material used more choice of glass fiber, polyamide fiber Or wire and other high-strength materials, both play a fixed role in the cord, while the use of belt to improve the rigidity of the tread. The rigidity of the side of the tire is less than the rigidity of the tread, so that the side of the tire is deformed by the lateral force of the ground during turning, thus ensuring that the touch area of ??the tread remains basically unchanged. Radial tire compared with ordinary slanting tire, flexible, good wear resistance, rolling resistance is small, good adhesion, good cushioning performance, carrying capacity, easy to pierce; drawback is the sidewall easy to crack, due to lateral deformation , Resulting in less lateral stability of the car, manufacturing technology requires high cost.
