A method and system for measuring a load on a tire while the vehicle traveling that include a microprocessor, a tire pressure sensor that is fixed to the tire, and an electromechanical sensor that is fixed to a point on the tire. The electromechanical sensor generates a beginning signal when the point begins to be part of the flat tire contact patch of the tire with the ground, and an ending signal when this point ceases to be part of the patch. The microprocessor calculates the patch contact time period, calculates the flat tire contact patch length from the radius of the tire and the ratio between the patch contact time period and the complete tire rotation period, and calculates the load on the tire from the tire pressure as measured by the pressure sensor and the length of the flat tire contact patch.
