Abstract: A method for determining the moisture of a ground on which a tire mounted on a vehicle is running, the tire being fitted with a sensor configured to acquire a measurement signal representative of the change in the curvature of the tire as it runs over a ground, comprises the following steps: acquiring a measurement signal representative of the change in the curvature of the tire while it is running; determining measurement data comprising (a) a first parameter (KSin) representative of a rate at which the tire flattens on contact with the ground, and (b) a second parameter (KSout) representative of a rate at which the tire regains its shape on becoming separated from the ground; and determining the moisture of the ground as a function of the first parameter (KSin) and the second parameter (KSout).
