入りタイヤ。[Claims for Utility Model Registration] (1) In a pneumatic tire having a tread portion consisting of a block surface pattern, the tread portion includes a central portion including the tire equatorial plane and a pair of adjacent portions on both sides of the central portion. The block has a central block provided at the center and side blocks provided at the side ends, and the negative rate of the central block is 76 to 82%, and the negative rate of the side end block is 76 to 82%. A pneumatic tire having a negative ratio of 70 to 76%, and a negative ratio at the side end portions being at least 4% smaller than a negative ratio at the central portion. (2) The center block and the side block tires are arranged substantially in the direction of the rotation axis, and arranged so that the center line of the center block in the direction of the rotation axis and the center line of the side blocks in the direction of the rotation axis substantially coincide with each other. A pneumatic tire according to claim 1 of the utility model registration claim, characterized in that: (3) Each substantially rectangular block in the central portion has a length in the rotation axis direction that is longer than the length in the circumferential direction, and each substantially rectangular block in the side end portion has a length in the circumferential direction that is longer than the length in the rotation axis direction. A pneumatic tire according to claim 1, characterized in that the pneumatic tire has a length.
