A pneumatic tire comprising a tread composed of a rubber composition, the rubber composition containing 30 to 120 parts by mass of silica having a BET specific surface area of 180 to 280 m 2 /g based on 100 parts by mass of a rubber component, wherein, under a normal state with no load where the pneumatic tire is mounted with a normal rim and filled with a normal internal pressure, a grounding surface shape in which a normal load is applied and the tread is pressed against a plane surface satisfies the following equation (1): 0.95 ≦ SL0/SL80 ≦ 1.6 (wherein, SL0 is a ground contact length in a circumferential direction of the tire on a tire equator, and SL80 is a ground contact length in a circumferential direction of the tire on a position away from the tire equator by a distance in a tire axial direction of 80% of a tread grounding half width.) |
