Description

Technical Field

[0001] This utility model relates to the field of tire technology, and in particular to a high wear-resistant tire. Background Technology

[0002] As the mainstay of domestic freight transportation, the development of trailers directly impacts the efficiency of road transport. Compared with other modes of road transport, trailers are easier to use for swapping and roll-on / roll-off (Ro-Ro) transport, thereby improving transport turnover efficiency and reducing empty load rates. Swap-on / roll-off transport involves a tractor unit switching trailers upon arrival at the destination, continuously transporting other trailers and reducing loading and unloading waiting time. Ro-Ro transport, on the other hand, involves directly loading containers and trailers onto ships and onto shore, a modern transport management method that directly intermodalizes road and water transport, shortening the conversion time for multimodal transport.

[0003] During each turn, the rearmost tire of a trailer slides on the road surface due to traction, resulting in significant lateral friction with the ground. Furthermore, the structure and operating system are subjected to other complex forces during turning, leading to greater tire wear, which intensifies over time. Tire wear alters tread shape, stiffness, and contact characteristics, thus affecting the tire's dynamic performance.

[0004] Therefore, those skilled in the art have provided a tire with high wear resistance to solve the problems mentioned in the background art. Utility Model Content

[0021] Furthermore, the tire body material is mainly filled with silica with a filling amount greater than 70 phr;

[0022] The above technical solutions ensure wear resistance and wet grip performance.

[0023] Furthermore, the tire body is made of a mixture of pure rubber emulsion styrene-butadiene rubber, solution styrene-butadiene rubber, and polybutadiene rubber;
