<P>PROBLEM TO BE SOLVED: To mitigate a stress from being concentrated to a recess by deformation of a sidewall part while a load acts thereon, without enlarging a curvature radius of an opening of the recess indicating a wearing state of the sidewall part. <P>SOLUTION: A tire includes a first recess 30 and a second recess 32. The first recess 30 is opened on a surface 24A of a sidewall part positioned inside a tire radial direction of a tread part, a center P of an opening 30A is positioned within an area in the tire radial direction from a widest part of the tire to an outer end in a tire width direction on a surface of the tread part, and a wearing state of the sidewall part is indicated with a depth from the surface 24A of the sidewall part. The second recess 32 is opened on the surface 24A of the sidewall part and disposed around the first recess 30. <P>COPYRIGHT: (C)2013,JPO&INPIT |
