The whole structure is uniform throughout; the crown and sidewalls of the tire have similar mechanical properties. With a radial construction, the ply cords radiate out at degree angles to the center line of the tread. In addition, the crown is made from layers that form a belt. As a result, the crown and sidewalls have their own particular characteristics. Due to their soft sidewalls, the crowns of radial tires stick to the road on contact. Their footprint, shorter but wider than that of a bias tire, provides added grip when leaning in heavily on corners.
The pressure of the air in contact with the tire surface is distributed more effectively with radial tires, which results in more even tread wear over time.
Radial tires also provide greater comfort at higher speeds, once again as a result of their soft sidewalls, which absorb the impact of imperfections on the road surface. On the other hand, bias tires are able to carry a greater weight because their sidewalls are more rigid.
At high speeds, bias tires can become so deformed that their performance is affected. The tyre crown and sidewall belong to the same ply, which makes the tyre stress concentrated. The deformation of the sidewall is directly transmitted to the tread, leading to unstable ground contact area and poor ground grip. Moreover, the uneven stress on the tyre tread causes serious wear in the middle and short service life of the tyre.
In addition, the diagonal tyre is composed of nylon cords with poor thermal endurance. After running for many times in the alternating environment of cold and hot, the nylon cord becomes fatigued, reducing the tensile force and causing a sudden tyre explosion, which poses a great safety hazard. A lot of tyres that seem to be in perfect condition suddenly explode, causing a huge impact on driving safety. Also, diagonal tyre is with high sidewall stiffness, poor comfort, high tyre temperature during long-distance and high-speed driving and poor heat dissipation, so it is not suitable for high-speed driving.
Radial ply tyres are commonly used in cars nowadays because of their outstanding advantages such as better ground grip and the stability at high speed, while diagonal tyres have basically been eliminated with only a few low-speed and heavy-duty trucks or construction machinery still in use.
Due to the small number of plies and small friction between them, the tyre temperature rises slowly and drops quickly, which can meet the demand for high-speed driving of automobiles. The main disadvantage of the radial-ply tyre is that the tyre side is thin, which may cause lateral deformation, leading to slightly poorer lateral stability.
It also requires high manufacturing technology and high cost. Email Us: info aulicetyre. Drive Tire Trailer Tire.
