Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a tire of which good durability and quietness are realized.SOLUTION: A tire 2 comprises a dimple arrangement area R, which is extended in a circumferential direction, on a side surface thereof. The dimple arrangement area R comprises multiple dimples 44 and a rand 46 as a part other than the dimples 44. The rand 46 includes a contour 54 of a Voronoi region 52 when the dimple arrangement area R is Voronoi-divided on the basis of multiple generatrices S located in the dimple arrangement area R, and is so formed as to be along the contour 54. The dimples 44 are formed on a part other than the rand 46 in the arrangement area R. Location of the generatrices S includes an irregular part. Preferably, a minimum distance between the Voronoi-divided generatrices S is 10 mm or longer.SELECTED DRAWING: Figure 1
