PROBLEM TO BE SOLVED: To provide a pneumatic tire which suppresses uneven wear.SOLUTION: A profile of a tread 4 of a tire 2 has a circular arc TC1 located on a center of the tread 4 and a pair of circular arcs TC2 located on the axial direction outer side of the circular arc TC1. A curvature radius TR1 of the circular arc TC1 is larger than the curvature radius TR2 of the circular arc TC2. When an intersection between a radial direction outer surface of a second layer of a belt 14 and an equatorial plane is set as Pc, a pair of end points of the radial direction outer surface of the second layer is set as Pe, a virtual circular arc passing through three points of the intersection Pc and a pair of end points Pe is set as BC and a curvature radius of the circular arc BC is set as BR, the curvature radius BR is 900 to 1100 mm. A ratio (TR2/BR) of a curvature radius TR2 to the curvature radius BR is 0.38 to 0.63.SELECTED DRAWING: Figure 2 |
