Method for determining the load applied to a tire

A method for determining a load of a tire mounted on a wheel of a vehicle and running along a ground, the tire being equipped with a sensor configured to acquire a measurement signal representative of a change in curvature of the tire as the tire runs along the ground, the method comprising the following steps:

• acquiring, by the sensor, a measurement signal representative of the change in curvature of the tire during running;
• obtaining a measurement of an internal pressure of the tire;
• determining, from the measurement signal, measurement data comprising 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;
• obtaining a firmness factor representative of a condition of firmness of the ground, which is derived from measurements taken while the tire is rolling over the ground;
• and
• determining the load of the tire as a function of the first parameter, of the firmness factor, and of the internal pressure of the tire.
