[0001] The present application relates to the technical field of tires, and in particular to a high-load-bearing all-steel radial tire. Background Art
[0002] With the increasing number of trucks, buses, and construction vehicles, the requirements for tires are becoming increasingly demanding. The all-steel radial tire is a tire type with an advanced structure and excellent performance. Unlike traditional bias tires, the main advantages of this all-steel radial tire include longer service life, lower rolling resistance, and better fuel economy. It can be widely used in trucks, buses, and construction vehicles.
[0003] In the related art, all-steel radial tires use steel wire materials in both the tire carcass and belt layers, and the tire carcass cord layer is arranged vertically at a ninety-degree angle. Since the steel cord layer of the tire carcass is parallel to the driving direction, the tire deforms less during driving and can more effectively disperse pressure, thereby reducing tread wear and extending service life. However, during use, the sidewall area of the tire is generally weaker and is easily damaged when facing a lateral impact, such as bulging, cracking or puncture. Especially when the vehicle passes through uneven roads or encounters sharp objects, the sidewall's impact resistance is weak, which may cause sidewall damage or even a tire blowout.
