According To The Structural Design

Divided into oblique line tires, radial tires. The fundamental difference between radial and oblique tire is the carcass. The carcass of the oblique line tire is a diagonal cross layer, and the meridian Tire is a multilayer cross material of polymer, the top layer is a steel band woven from the steel wire, which can reduce the chance of the tire being punctured by foreign body.

Diagonal tire of the line of the cord crossed by diagonal lines, hence the name. The characteristic is the tread and the tire side strength is big, but the tire side rigidity is big, the comfortableness is poor, because of the high speed, the cord movement and the friction big, is not suitable for the high speed traveling. With the continuous improvement of radial tire, the skew tire will be basically eliminated.

The cord alignment of radial tire is consistent with the Meridian section of Tyre, and the cord layer is the basic skeleton of Tyre. As a result of driving tires to bear a larger tangential force, in order to ensure the stability of the cord, there are several layers of the outside of the high-strength, not easy to stretch the material made of the band layer (also known as hoop), the direction of the cord and the meridian section of the larger angle. From the design, the skew line tires have many limitations, for example, because of the strong friction of crossed cords, it makes the carcass hot, so it accelerates the wear of tread, and its cord layout can not provide excellent maneuverability and comfort, but the steel wire belt of radial tire has good flexibility to adapt to the irregular impact of pavement. and durable, its cord structure also means that there is much less friction in the car than the skew line, thus obtaining a longer tread life and better fuel economy.

At the same time, the radial tire has its own characteristics to make the tire without inner tube possible. There is a recognized advantage of tyre-free tires, that is, when a tyre is punctured, it does not explode like a diagonal tire with an inner tube (which is very dangerous), but allows the tire to maintain air pressure over a period of time and improve the safety of the car. In addition, there is a better grip on the radial tyre than the skew line tyre.

Compared with conventional slash tires, radial tires large elasticity, good abrasion resistance, small rolling resistance, good adhesion performance, good buffering performance, large load carrying capacity, not easy to puncture; The disadvantage is that the tire side is easy to crack, because the lateral deformation is large, the lateral stability of the vehicle is slightly worse, the manufacturing technology requires high and the cost is higher.
