<p>PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of further enhancing inhibitory effect on a hydroplaning phenomenon.SOLUTION: In the pneumatic tire, at a tread part 2 are provided at least two circumferential grooves 3 extending continuously in a tire circumference direction, thereby partitioning a land part 4 between the circumferential grooves 3. The tread part 2 has a virtual tread profile 2P that joins smoothly tread ends Te along a tire inner cavity surface S in a tire median cross-section including a tire rotating shaft. The land part 4 includes a protruding part 7 extending further outside in a tire radial direction than the virtual tread profile 2P. The protruding part 7 has a protruding profile 7P protruding toward outside in the tire radial direction in a tire median cross-section, and the protruding profile 7P is formed of a plurality of circular arcs with different curvature radii.</p> |
