Claim 12:
13. A vehicle comprising:
at least one tire mounted on a wheel of the vehicle;
at least one sensor sensitive to a change in curvature of the tire and configured to generate a measurement signal representative of the change in curvature of the tire as the tire runs over a ground;
at least one pressure probe designed to provide a measurement of the internal pressure of the tire; and
a data processing unit configured to receive the measurement of the internal pressure of the tire and measurement data derived from the measurement signal representative of the change in curvature of the tire as the tire runs over the ground and to determine the firmness of the ground as a function of the measurement data, the measurement data comprising:
(a) a first parameter representative of a length of a contact patch in contact with the ground during a revolution of the wheel bearing the tire, and
(b) a second parameter representative of a rate of flattening of the tire upon contact with the ground during a revolution of the wheel bearing the tire,

the vehicle being configured to implement the method according to claim 1.
