Patent ID: 8550135

Claim:
A pneumatic tire comprising: at least three belts arranged on a tire-radial-direction outer side of a carcass; and a belt edge cushion arranged between a tire-width-direction outer end portion of a second belt that is secondly arranged from the tire-radial-direction outer side and a tire-width-direction outer end portion of a third belt that is thirdly arranged, wherein an inner part of the tire-width-direction outer end portion of the second belt curves radially inwardly toward the third belt in the position of the belt edge cushion, a tire-width direction outer end of a first belt that is firstly arranged from the tire-radial-direction outer side is provided in a position close to a tire-width-direction inner end of the belt edge cushion in the tire width direction such that a tire-width direction distance Wd between the tire-width direction outer end of the first belt and the tire-width direction inner end of the belt edge cushion is in a range of 0<Wd/WB<0.30 of a width direction WB of the belt edge cushion, and a curvature radius Trb of a portion of the second belt, which portion curves to the tire-radial-direction inner side, and a curvature radius Tra of the first belt have a relationship of 0.03<Trb/Tra<0.20.
