A numerical method for predicting the tire wear amount has been introduced in this paper to reduce the troublesome time and cost that are required for outdoor and indoor wear tests of a model tire at the design stage. The frictional energy dissipation through the tire footprint contacting with the abrasive ground was computed by the frictional dynamic simulation of the 3D patterned tire model. The driving conditions in the actual outdoor wear test were classified into nine modes for which corresponding occurrence frequency weights and load conditions were specified. The frictional energy rate was correlated with the tread wear rate by a power function wear rate model that was derived on an experimental basis. As illustrated through numerical experiments, the tread wear amount can be estimated by the proposed method in extremely short period of time once the outdoor driving and load conditions are specified. Furthermore, this numerical method can be a useful tool to determine the rubber compound, the tread pattern, and the material and structural compositions in the design of a tire model, which satisfies the preset wear performance.
