A method to predict tire tread wear in the laboratory was introduced based on low severity tire wear mechanism. The tire acceleration distribution was used to determine the slip ratio of the test. Sample load was determined using vehicle weight and tire inflation pressure.

The mechanism of tire wear and rubber wear test methods have been researched for more than a century ever since the advent of pneumatic tires. In 1929, Lambourn was the first to propose and patent a laboratory wear tester that correlated with tire wear test results. From excerpt of Lambourn‘s results, Mouri found a decent correlation between rubber wear test and tire test, where the correlation coefficient was as high as R2= 0.96, although the range was quite wide with nearly four-fold difference between the worst compound and the best compound.
