Abstract

A method for estimating wear of each of circumferential tread zones of a tire by the use of a computer is disclosed. A tire model of the tire comprising model's circumferential tread zones is defined. A simulation for running the tire model under rolling conditions for free-rolling, braking, driving and cornering is performed to obtain a first average wear energy of each model's circumferential tread zone under each rolling condition. With respect to a given running pattern of the tire, occurrence frequencies of the respective rolling conditions occurring in the running pattern are defined. For each circumferential tread zone, a second average wear energy of the concerned circumferential tread zone when the tire is run according to the running pattern is calculated such that the first average wear energies under the respective rolling conditions, of the model's circumferential tread zone of the concerned circumferential tread zone are respectively weighted by the occurrence frequencies of the respective rolling conditions. Wear of each circumferential tread zone is estimated based on the calculated second average wear energy of the concerned circumferential tread zone.
