Description

Technical Field

[0001] The utility model belongs to the technical field of automobile tires and relates to a wear-resistant and aging-resistant tire. Background Art

[0002] Automobile tires are circular elastic rubber products that roll on the ground and are usually installed on metal rims. They play an important role in supporting the vehicle body, buffering external impacts, achieving contact with the road surface, and ensuring the driving performance of the vehicle. Automobile tires are often used under complex and harsh conditions, so they must have high load-bearing performance, traction performance, buffering performance, high wear resistance, flexibility resistance, and low rolling resistance and heat generation. Automobile tire aging is an inevitable process. After long-term use, tires will age, which will cause a series of problems.

[0003] The surface of aged tires is hardened and prone to cracks, increasing the risk of blowouts and tire cracking and air leakage. Under high-speed driving or heavy load conditions, aged tires are more likely to blow out or crack, seriously threatening driving safety. Therefore, the aging of automobile tires is an issue that needs to be taken seriously. Long-term use of aged tires will have adverse effects on the safety, performance, fuel economy and comfort of the vehicle. Therefore, a wear-resistant and anti-aging tire is urgently needed to solve the above problems. Utility Model Content
