Abstract
Described is a method of optimizing tire pressures in order to obtain maximum tire tread life and performance. The method involves calculation of the live and dead loads on each individual tire of the vehicle. Grown diameter of the tires in use is obtained from published data sheets. The grown diameter is then multiplied by an empirically derived tread length determining factor to obtain an optimum tread length in contact with the road surface. In turn the tread length is multiplied by effective tread width to obtain a footprint area for the tires. Finally, the load carried by the individual tires is divided by the footprint area to obtain an optimum inflation pressure.
