PROBLEM TO BE SOLVED: To provide a pneumatic tire which can secure durability even when load dependency of cornering force is reduced.SOLUTION: A pneumatic tire 1 includes a belt 4 formed of two inclination belt layers 4a, 4b intersecting each other between the layers. When the tire is mounted on an application rim, is filled to a specified internal pressure, and has no load, the two inclination belt layers have different widths in a tire width direction. When the width in the tire width direction of the one wider inclination belt layer is W1 and the width in the tire width direction of the other inclination belt layer is W2, a ratio W2/W1 satisfies a relational expression 0.25≤(W2/W1)≤0.8. In addition, a reinforcing belt 6 formed of one or more circumferential belt layers 6a, 6b is formed on an outer side of the belt in a tire diameter direction. Circumferential rigidity of the reinforcing belt in an area in the tire width direction between an end part of the one inclination belt layer and an end part of the other inclination belt layer is higher than circumferential rigidity of the reinforcing belt on an inner side in the tire width direction from the area.SELECTED DRAWING: Figure 1 |
