Abstract
The rolling parameters of a tire on a rolling surface are evaluated, and more specifically a tire's adhesion potential on a rolling surface is estimated. A method and a system enabling such estimation are disclosed.

A method for estimating adhesion potential of a tire on a rolling surface, the tire being installed on a vehicle, and the method comprising the following steps:
- a first step of estimating a force experienced by the tire as a function of a vehicle model and a state observer;
- a second step of estimating a force experienced by the tire as a function of a thermomechanical model of the tire;
- a step of statistically comparing the forces determined during the first and second estimating steps, and
- a step of determining, as a function of a result of the comparing step, a value of the adhesion potential of the tire on the rolling surface.
