Abstract
A green tire includes a surface layer defining a green tire surface and made up of a plurality of windings of an unvulcanized rubber tape. A part of each of the windings is exposed on the green tire surface so that the exposed part has a width of from 50% to 80% of the width Wof the rubber tape. Each of the windings has a substantially rhomboid cross section and has one end at an acute angle corner exposed on the green tire surface and the other end at the opposing acute angle corner. An angle theta of a diagonal line of the rhomboid drawn between the one end and the other end is not more than 30 degrees with respect to a tangential line to a profile line of the green tire surface.
