<P>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. <P>SOLUTION: In the pneumatic tire 1, an angle θ falls within the range of 0.025×β+1.0≤θ≤0.045×β+2.5; the ratio Rc/Rs between a curvature radius Rc of the center area and a 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 width L and a tread development half-width TDW/2 falls within the range of 0.2≤L/(TDW/2)≤0.7. Additionally, a maximum groove width dc of a groove formed in the center area and a maximum groove width ds of a groove formed in the shoulder area satisfy 1.2 [mm]≤dc/ds≤2.0 [mm]. <P>COPYRIGHT: (C)2012,JPO&INPIT |
