Our company has developed 445/50R22.5 specification wide base tires for a well-known large tire enterprise and listed company. Recently, after durability testing, the tires have not been damaged after 150 hours of operation, reaching the limit set by the company's experimental equipment for single operation.

The wide cross-section and low flatness of wide base tires make design and process control difficult, and durability has always been a bottleneck in the design and production of tire industries both domestically and internationally. This wide base tire design has made breakthrough progress by optimizing the distribution of shoulder materials and adopting a special belt structure to optimize the stretching of the tire body and belt steel cords, overcoming the problems of shoulder clearance and crown burst that are prone to occur during durability testing of wide base tires. The durability performance test results of the 445/50R22.5 specification wide base tires designed and developed by our company are at the leading level in the industry compared with the test results of similar series tires at home and abroad.
