发明名称 PNEUMATIC TIRE
摘要 [Object] To provide a pneumatic tire which is excellent in durability. [Solution] A tire has a large number of dimples 62 on sidewalls thereof. The contour of each dimple 62 is composed of a first circular arc 66, a second circular arc 68, a first connection line 70, and a second connection line 72. The curvature radius R2 of the second circular arc 68 is larger than the curvature radius R1 of the first circular arc 66. The first connection line 70 is a straight line. The first connection line 70 connects one end 78 of the first circular arc 66 to one end 80 of the second circular arc 68. The second connection line 72 is a straight line. The second connection line 72 connects the other end 74 of the first circular arc 66 to the other end 76 of the second circular arc 68. Preferably, the length L of a longest line segment that can be drawn within the contour of each dimple 62 is larger than the sum of the curvature radius R1 of the first circular arc 66 and the curvature radius R2 of the second circular arc 68.
