Abstract
A pressure sensor is used to automatically calculate physical parameters of a tire, for example, groove area fraction or shoulder center ratio. In one approach, a pressure sensor measures the pressure distribution produced by a tire when a known load is applied to the tire while it is resting on or traversing the pressure sensor. The resulting pressure map corresponds to tread area and features of the tread contact area.
