The tire wear tests were performed for rubber compounds with different physical properties on the different road surface temperature using the same vehicle. It is clear that the temperature dependence of wear resistance were different for the different rubber compounds. The wear resistance W is found to be scaled using the fracture energy F (MJ/m3) and the storage modulus E* (MPa) for the rubber compound as follows:
W = c(Fa / E*b)(a, b, c=the constant number)
Temperature dependence of wear resistance is considered to be caused by the different contribution of F and E* values.
