PURPOSE:To quite obviously discriminate the wearing degree of a tire, by forming a paddy part, with a tone of different color from color of the tire, in a paddy part internally from a usable range of the tire in a tread part. CONSTITUTION:A different colored part 3 from normal tire color is formed in a tire tread paddy part internally from a tire usable range 2. A tire 1 of this constitution is worn to a usable range 2, if in a slip hazardous state, the different colored layer is disclosed. Accordingly, wear of the tire, beyond a limit in a hazardous state, can be quite obviously discriminated to prevent a hazard. |
