Abstract: A pneumatic tire whose mounting location on a vehicle is specified and which comprises a belt disposed radially outside the carcass and composed of belt cords laid at an angle of from 15 to 40 degrees with respect to the tire circumferential direction, and a band disposed radially outside the belt and composed of first and second band cords laid at an angle of not more than 5 degrees with respect to the tire circumferential direction. The band comprises an inboard first part composed of the first band cord having a first modulus M1, and an outboard second part composed of the second band cord having a second modulus M2 more than the first modulus M1. The number of laminated plies of the band in the inboard first part is more than the number of laminated plies or a single ply of the band in the outboard second part.

Abstract: A pneumatic tire includes a tread portion, carcass, inclined belt, and circumferential belt. The inclined belt is formed by inclined belt layer(s) including cords inclined relative to the tire circumferential direction. A circumferential main groove is provided in the tread portion. The inclined belt includes a high-angle inclined belt layer in which the cords are at an inclination angle of 35° to 90° relative to the tire circumferential direction. In at least one tread half portion, an edge of the high-angle inclined belt layer in the tire width direction is positioned further outward in the tire width direction than the circumferential main groove disposed furthest outward in the tire width direction. The interval in the tire width direction from the edge to the center of the circumferential main groove is 0.2W1 to 0.35W1, where W1 is the width of the high-angle inclined belt layer in the tire width direction.
