OPTIMAL BODY PLY SHAPE FOR HEAVY TRUCK TIRE INCLUDING BELT PLIES IN CROWN PORTION

摘要

A tire having uniform inflation growth is provided. The tire includes a body ply that is displaced from the conventional equilibrium curve along the bead, sidewall, and shoulder portions of the tire in a manner that provides more uniform inflation growth from bead portion to bead portion. Such construction reduces load sensitivity, reduces or eliminates the tire break-in period, and/or decreases the propensity for cracking - particularly along a groove bottom of the tread in the shoulder.
