PROBLEM TO BE SOLVED: To provide a pneumatic tire that improves abrasion resistance of the center area while maintaining abrasion resistance of the shoulder area under a high internal pressure.SOLUTION: In the pneumatic tire 1, (1) an angle &thetas; falls within the range of 0.025×&bgr;+1.0≤&thetas;≤0.045×&bgr;+2.5; the ratio Rc/Rs between the curvature radius Rc of the center area and the curvature radius Rs of the shoulder area falls within the range of 10≤Rc/Rs≤50; and the ratio L/(TDW/2) between a reference development half-width L and a tread development width TDW/2 falls within the range of 0.2≤L/(TDW/2)≤0.7. Additionally, (2) a distance ts between points Q and R falls within the range of 4.0 [mm]≤ts≤8.0 [mm]. |
