Abstract
A tire having favorable moldability, having higher black density than conventional, and can with enhanced contrast, and also having high durability in the pattern region, as well as a tire molding die for molding this tire. A tire includes a pattern region including a plurality of projections that project from a reference plane, each of the plurality of projections includes, in a cross-sectional shape, a base portion that rises up from the reference plane sloping towards an inner side of the projection; a tip portion provided more to a tip end than the base portion, and rising up from the base portion, sloping towards an inner side of the projection; in which the angle at which the tip portion rises is greater than an angle at which the base portion rises, based on the reference plane.
Claims14
A tire comprising:
- a pattern region provided to at least part of an outer surface of a sidewall in a visually recognizable state as a different site than a surrounding of said part, wherein
- the pattern region includes a plurality of projections that project from a reference plane,
- each of the plurality of projections includes, in a cross-sectional shape,
- a base portion that rises up from the reference plane sloping towards an inner side of the projection;
- a tip provided more to a tip end side than the base portion, and rising up from the base portion sloping towards an inner side of the projection;
- an apex portion provided to a tip end of the tip;
- and
- a recess portion that indents from the apex portion towards a side of the reference plane at a center of the projection,
- wherein, based on the reference plane, an angle at which the tip rises is greater than an angle at which the base portion rises.
