Abstract
A pneumatic tire including a carcass, a belt arranged at the outside of the carcass in a radial direction and having at least two belt layers, at least one belt reinforcing layer arranged so as to overlap with the belt and extend over a widthwise outer end thereof, and a tread rubber arranged at the outside of the belt in the radial direction. A pair of split auxiliary belt layers are arranged so as to overlap at least with both widthwise outer end portions of a widest-width belt reinforcing layer. Reinforcing elements having an inclination angle different from that of reinforcing elements in the belt reinforcing layer are embedded in the split auxiliary belt layer for decreasing the wearing rate at the tread end portion of the tire to effectively control irregular wear.
