Tire

A tire testing apparatus and method for measuring the local stiffness of a tire. The apparatus includes a force producing mechanism, a force measuring device, a force transmitting member, and a measuring device. The force transmitting member applies a force to a tire surface and the measuring device measures the distance of the displacement of the tire surface caused by the force. A tire testing method comprising mounting a tire on a tire testing apparatus to measure a local stiffness of the tire. The method further comprises inflating the tire, applying a force to a local area of the tire, monitoring the force, measuring a distance corresponding to the local deflection, and calculating a local stiffness.
