Patent ID: 6959746

Claim:
A pneumatic tire comprising a carcass toroidally extending between a pair of bead portions, a belt arranged at the outside of the carcass in a radial direction and comprised of at least two belt layers, plural reinforcing elements embedded in said layers being crossed with each other with respect to an equatorial plane of the tire, at least one belt reinforcing layer arranged so as to overlap with the belt and extend over a widthwise outer end thereof and embedding plural reinforcing elements therein each extending substantially in a circumferential direction while bending in a wavy or zigzag form, and a tread rubber arranged at the outside of the belt in the radial direction, further comprising a pair of split auxiliary belt layers arranged so as to overlap at least with both widthwise outer end portions of a widest-width belt reinforcing layer and comprised of at least one ply containing plural reinforcing elements embedded therein at an inclination angle with respect to the equatorial plane different from that of the reinforcing element in the widest-width belt reinforcing layer, wherein when the split auxiliary belt layers overlap with only the widest-width belt reinforcing layer and an axial distance from the equatorial plane of the tire to the tread end is W, a width H of the split auxiliary belt layer is within a range of 0.10W-0.60W and a distance M from the equatorial plane of the tire to a widthwise outer end of the split auxiliary belt layer is within a range of 0.90W-1.20W.
