PROBLEM TO BE SOLVED: To maintain comfortableness and drainage performance and besides, to improve run-flat durability.SOLUTION: There is provided a pneumatic tire the rotating direction R of which is specified. A land ratio of a center virtual area 5A which is an area between a pair of center virtual lines 5c, 5c passing through both tire axial-direction ends of a center block 5 and extending in the tire circumferential direction is 0.75 to 0.85, and a land ratio of a middle virtual area 6A which is an area between a pair of middle virtual lines 6c, 6c passing through both tire axial direction-ends of a middle block 6 and extending in the tire circumferential direction is 0.65 to 0.75. Center lateral grooves 4A and middle lateral grooves 4B are inclined to the direction of the rear touching side of the rotation direction of the tire from the tire equator C side toward ground-touching end Te sides. Groove width of center lateral grooves 4A and middle lateral grooves 4B is 4.0 to 7.0 mm. Groove width of center main grooves 3A is smaller than width of center lateral grooves 4A, and groove width of center lateral grooves 4A is smaller than the groove width of middle main grooves 3B. |
