Abstract
A tire includes a projection disposed between a tread end and a maximum width position on a side surface. The projection includes a groove that extends through an outer side surface in a circumferential direction. The tire is preferably produced by using a mold which has a first part and a second part and in which a dividing line between the first and the second parts extends in the circumferential direction and comes into contact with the side surface, and the groove preferably overlaps an imaginary line, on the side surface, corresponding to the dividing line. A width of the groove is preferably not less than 1.5 mm and preferably not greater than 3.0 mm.

A tire comprising:
- a plurality of projections spaced apart in the circumferential direction and disposed between a tread end and a maximum width position on a side surface of the tire;
- and
- tread having a plurality of blocks extending to the tread end, wherein
- each of the plurality of projections includes only a single groove that extends through an outer side surface of its projection in the circumferential direction,
- the entirety of each groove is disposed outward of the center of its projection in a radial direction,
- a depth of each groove is not less than 15% of a thickness of its projection and not greater than 30% of the thickness of its projection, and
- each of the plurality of projections is formed continuously with a corresponding block.
