Abstract: A pneumatic tire includes a carcass ply extending from one bead structure to another bead structure. Each bead structure includes a plurality of circumferentially wound metal wires defining a cross-sectional profile of a bead. The profile has a radial height to axial width ratio greater than 1.0 and a bead orientation angle between 30 degrees and 60 degrees.

Abstract: A pneumatic tire includes a tread, two inextensible annular beads, a carcass ply having two turnup end portions, and an annular cap structure encompassing one of the turnup end portions. Each turnup end portion is wrapped around one of the annular beads. The cap structure has a U-shaped cross-section for surrounding the turnup end portion. The cap structure is constructed of reinforced fabric with fibers oriented in the range from ?45° to +45° with respect to a radial direction of the pneumatic tire.

Abstract: A pneumatic tire includes a tread, two annular bead portions, a carcass ply having two turnup end portions, a first reinforcing structure disposed at one of the bead portions, and an annular first cap structure encompassing a first end portion of the first reinforcing structure. Each turnup end portion is wrapped around one of the annular bead portions. The first reinforcing structure is disposed at one of the bead portions. The first cap structure encompasses the first end portion of the first reinforcing structure. The first cap structure has a U-shaped cross-section for surrounding the first end portion. The first cap structure is constructed of reinforced fabric with fibers oriented in the range from ?45° to +45° with respect to a radial direction of the pneumatic tire.
