Research on the mechanism of tire wear and its rubber test methods has been carried out for more than a century, ever since the advent of pneumatic tires, and there are still numerous new reports being published even now. ISO 23794:2015 standardizes the general outline of 14 types of rubber wear test methods, such as the Akron wear test, the Lambourn wear test and the DIN wear test. The Akron wear test and Lambourn wear test, which introduce slippage between the pavement surface and the rubber sample, are suitable for evaluating tire tread wear resistance. Historically, Lambourn was the first to propose a laboratory wear tester that correlated with tire wear test results.
