Abstract: A method for estimating the overall wear of a tyre having a crown, the crown comprising a tread having a mean thickness E, the tyre delimiting an internal cavity, comprises the following steps: acquiring a transfer function F of the tyre on a reference ground depending on influencing factors and the thickness E; acquiring a passage function ? of the mounted assembly, said passage function being defined for a section of road; in a measurement cycle determining a force FX and a rate of slip g % at the wheel centre of the tyre, 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; determining an inflation pressure P1 of the internal cavity.

Abstract: Die (1) representing a tread pattern model for a tread of a tire to be molded, said die being made up of a die body (2) and at least one insert (10) attached to the body of said die, covering at least one of the surfaces of the grooves (4) in the body (2), the insert having at least one substantially flat surface provided with textures.
