1. A method for evaluating thermal stresses associated with use of a tire mounted on a rim, the method comprising steps of:
- measuring a temperature of a gaseous fluid contained in an internal cavity of the tire at regular time intervals, in order to obtain a fluid temperature (TAI);
measuring a temperature at location on the rim at regular time intervals, in order to obtain a rim temperature (Tj);
determining an estimated temperature (TZI) at at least one internal zone of materials of which the tire is made using a pre-established law connecting the estimated temperature (TZI) to the fluid temperature (TAI) and the rim temperature (Tj).

Abstract
A method for evaluating the thermal stresses associated with the use of a tire mounted on a rim, the method comprising the steps during which a temperature of a gaseous fluid contained in an internal cavity of the tire, and a temperature of the rim, are measured at regular time intervals, and a temperature at at least one internal zone of the materials of which the tire is made is estimated using a pre-established law connecting this temperature to the temperature of the gaseous fluid contained in the internal cavity of the tire and to the temperature of the rim.

13. A system for evaluating thermal stresses associated with use of a tire mounted on a rim, the system comprising:
-
(A) a computer; and (B) a memory storing executable code that, when executed by a processing unit of the computer, causes the computer to perform a method that includes; (1) utilizing temperatures of a gaseous fluid contained in an internal cavity of the tire measured at regular time intervals to determine a fluid temperature (TAI) in the internal cavity of the tire, (2) utilizing temperatures at a location on the rim measured at regular time intervals to determine a rim temperature (Tj), (3) calculating an estimated temperature (TZI) at at least one internal zone of materials of which the tire is made using a pre-established law connecting the estimated temperature (TZI) to the fluid temperature (TAI) in the internal cavity of the tire and the rim temperature (Tj), wherein the temperatures of the gaseous fluid contained in the internal cavity of the tire, and the temperatures at the location on the rim are transmitted from the tire to the computer.
