<p>PROBLEM TO BE SOLVED: To provide a pneumatic tire which is improved in upset resistance while maintaining traveling performance at normal traveling.SOLUTION: A pneumatic tire 1 has a pair of shoulder main grooves 9 and a pair of shoulder land parts 10 at a tread part 2. The shoulder land parts are composed of block rows in which shoulder blocks 15 are aligned in a tire circumferential direction. Widths of the shoulder blocks 15 in a tire axial direction are 10 to 25% with respect to a tread grounding width TW. The pneumatic tire has at least one piece of a shoulder vertical sub-groove 16. The shoulder blocks 15 are composed of rubber compositions whose loss tangents tanδare smaller than 0.16.</p> |
