Abstract: A pneumatic tire has a tread with shoulders, a belt structure, a carcass, and a radial ply structure. The shoulders have a continuous curving radially outer profile so that the shoulders transition smoothly from the tread profile to the tire sidewalls. The locus of the radii defining the shoulder is located on the inner side of the tire. The tire has a belt structure formed of 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. Located radially inward of the axial edges of the annular layer is an annular reinforcing strip layer. The strip has a width of not greater than 30 mm and extends axially outward by a distance of not more than 10 mm.

Abstract: A pneumatic tire has 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 shoulders of the tire have a continuous curving radially outer profile so that the shoulders transition smoothly from the tread profile to the tire sidewalls. The tire has a belt structure formed of an annular layer of parallel cords, the annular layer having a pair of opposing annular edges and a continuous radius curve profile. Located radially inward of the axial edges of the annular layer of the belt structure is an annular reinforcing strip layer. The strip has a width of not greater than 30 mm and extends axially outward of the annular layer edges by a distance of not more than 10 mm.
