Effect of hydrogenation on the styrenebutadiene rubber (SBR) in terms of the mechanochemical wear behavior was studied focusing on the mechanisms of the mechanochemical reactions during the wear process. The wear test performed in the air and in a nitrogen gas atmosphere indicated that the oxygen molecules accelerated the mechanochemical wear.

Along with the innovative changes in the vehicle usage such as autonomous vehicle and shared driving, for example, supporting the safety driving by keeping the initial tire performance for long term will be increasingly important. In general, tire performance gradually changes due to the decrease of tread depth and the de gradation of rubber materials [1].
