Abstract
A method for estimating the overall wear of a tire having a crown, the crown comprising a tread having a mean thickness E, the tire delimiting an internal cavity, comprises the following steps: acquiring a transfer function F of the tire on a reference ground depending on influencing factors and the thickness E; acquiring a passage function β of the mounted assembly, said passage function being defined for a section of road; and in a measurement cycle, determining a force FX and a rate of slip g % at the wheel center of the tire, when running in a straight line involving variations in acceleration on the dry section of road; determining a load Z1 experienced by the mounted assembly; determining a temperature T1 of the mounted assembly; and determining an inflation pressure P1 of the internal cavity.
