PURPOSE:To facilitate the identification of the different inner structure of tire even in a tire with the same tread pattern by applying colored idification marks to the grooves arranged at least in the circumferential direction of tread. CONSTITUTION:A tire 1 is provided with a plurality of main grooves 4 linear in the circumferential direction of a tread 2, and sub-grooves 5 in the circumferential direction of tire to cross the main grooves 4. In this case, idification marks 6 colored, for example, with yellow are applied to the bottoms of grooves in all of the main grooves 4. The idification marks 6 are colored so as to change in color at every internal structure of tire, change the number of the main grooves 4 colored, and cover the sub grooves 5. It is thus possible to facilitate the internal structure by means of the idification marks 6. |
