TIRE WITH ROUNDED BEAD TOE AND A MOLD FOR FORMING THE TIRE.

摘要

A heavy load truck or bus tire for mounting on a 15 DEG drop center rim has a rounded bead toe that eliminates mounting problems and saves on material. The bead toe is defined by the bead seat (26) and bead toe end surface forming an included angle in a range of 105 DEG to 150 DEG . In addition, a transition point (30) between the bead seat and bead toe end surface is located relative to the bead seat point (28) as in a range of 0.95 to 0.97 of the axial distance from the tire center and at least 0.78 of the bead seat point radius. A mold for forming the tire is also disclosed..
