They are usually installed on metal rims, can support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects when driving, so they must have high load-bearing performance, traction performance, and buffering performance. At the same time, they are also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation.

[0003] In the prior art, automobile tires are insulators and the electric charge of the automobile cannot be discharged. To ensure the safety of the automobile and its passengers, the automobile uses suspended conductive belts or chains in contact with the ground to solve this problem. However, conductive belts or chains will increase the cost of automobile production, and the surface contact will also generate noise pollution. Utility Model Content

[0013] Beneficial effects: A conductive rubber strip is added to the sidewall, and the conductive rubber strip is extended to the end of the second belt layer by wrapping the sidewall. The second belt layer is connected to the first belt layer, and then to the cap layer.
