In a side portion of this tire, first direction ridge patterns and second direction ridge patterns are alternately arranged. In first direction ridge patterns 20, multiple main ridges 22A-22D and sub-ridges 26A-26D are formed protruding from the bottom surface 18A. The ridges are arranged in parallel such that the ridge extension directions are the same. The main ridge region 24 and the sub-ridge region 28 have different light reflection patterns. |
