Abstract: A heavy load truck or bus tire for mounting on a 15° 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 and bead toe end surface forming an included angle in a range of 105° to 150°. In addition, a transition point between the bead seat and bead toe end surface is located relative to the bead seat point 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.
