Abstract: A method of building an unequal bead diameter tire with conventional components and contour lengths which are substantially equal, the contour lengths being measured along the neutral axis of the carcass plies between the beads and a plane containing the mid-circumferential centerline of the tread. The tire is molded in a special configuration not usually employed in shaping a tire, i.e. the tread is unsymmetrical in relation to a plane which normally bisects the tread, and the lateral edges of the tread are radially offset and not equally spaced from the center axis of the mold which is normally the case when the conventional methods are used for molding and vulcanizing a tire.

Abstract: A simplified radial ply tire containing a high modulus single carcass ply and a high modulus single belt ply with the cords in the carcass ply extending radially in the sidewall and at a bias angle in the tread area. The cords in the belt ply extend at an opposite bias angle to those of the carcass ply. A pair of continuous low modulus cord reinforced shoulder strips are provided and extend circumferentially about the tire adjacent the outer edges of the belt structure. Belt coatings, ply angles, shoulder strip orientation, bead region construction and other features are also disclosed.
