Abstract:
1. A pneumatic tire comprising a tread with shoulders, a belt structure located below the tread, and a carcass with two sidewalls, two inextensible annular beads, and a radial ply structure, the radial ply structure having terminal ends located axially outward and radially inward of the belt structure, the tire characterized by: the shoulders each having a continuous curving radially outer profile; the belt structure comprising an annular layer of parallel cords directly adjacent to the radial ply structure, the annular layer having a pair of opposing annular edges and a continuous radius curve profile; an annular reinforcing strip layer located radially inward and directly adjacent of each annular layer edge along the edge of each annular layer, each strip layer having a width of not greater than 20 mm as measured between terminal ends of the strip layer, and one terminal end of the strip layer extending axially outward of the belt structure, the amount of axial extension of the strip layer being greater than 0 mm and not more than 10 mm; the annular reinforcing strip layer being formed from a plurality adjacent narrow strips, each narrow strip having width narrower than the width of the annular reinforcing strip layer, a sum of the widths of the narrow strips equaling the width of the annular reinforcing strip layer; the annular reinforcing strip layer thereby forming at least one ply of parallel reinforcing cords.
