<p>PROBLEM TO BE SOLVED: To improve snow road performance and steering stability performance.SOLUTION: A pneumatic tire is specified for direction of attaching to a vehicle. An outside middle land part 6 is provided with an outside middle lug groove 11 which contains a first outside middle lug groove 11A and a second outside middle lug groove 11B which is larger in length along tire axial direction, and a middle inclination groove 12 containing a first middle inclination groove 12A which is inclined to a second main groove 4 side passing through an inner end of a second outside middle lug groove 11B adjoining to and extending to one side along tire peripheral direction from an inner end of the first outside middle lug groove 11A, and a second middle inclination groove 12B which extends by inclining to the other side of tire peripheral direction and a first main groove 3 side from an inner end of the first outside middle lug groove 11A, for communication with the second outside middle lug groove 11B. The first middle inclination groove 12A gradually increases from the second main groove 4 side to the first main groove 3 side in terms of groove width. The second middle inclination groove 12B has a groove width smaller than the first middle inclination groove 12A.</p> |
