Patent ID: 8528613

Claim:
A pneumatic tire comprising: at least two cross belts that have codes forming an angle of 5 degrees or greater and 30 degrees or less with respect to a tire circumferential direction; a circumferential reinforcing layer that has a width smaller than smallest width of the cross belts, and that has codes forming an angle of 0 degrees or greater and 5 degrees or less with respect to the tire circumferential direction; a carcass located inside, in a tire diameter direction, relative to a cross belt being inside among the cross belts in the tire diameter direction; and a high-angle belt which is provided on an outer side of the carcass in the tire diameter direction, wherein outer edges of the high-angle belt extend further outwardly than outer edges of the circumferential reinforcing layer but further inwardly than outer edges of the cross belts in the width direction of the tire, and such that the outer edges of the high-angle belt are disposed offset in the width direction of the tire with respect to outer edges of the cross belts, at 100% internal inflation pressure, a distance X 1 between an equatorial plane of the pneumatic tire and an outer edge, in a tire width direction, of the circumferential reinforcing layer is not less than 60% and not more than 75% of a distance W between the equatorial plane and an outermost section of the carcass in the tire width direction, and at 5% internal inflation pressure, a distance Y between the equatorial plane and a separation section of the carcass and a belt outwardly adjoining the carcass in the tire diameter direction is not less than 95% and not more than 105% of a distance X 2 between the equatorial plane and the outer edge, in the tire width direction, of the circumferential reinforcing layer.
