Abstract: The pneumatic tire has a single carcass ply reinforced with parallel metallic cords, each cord composed of at least one filament having a tensile strength of at least (-2000.times.D+4400 MPa).times.95%, where D is the filament diameter in millimeters. The turnup portion of the single carcass ply 12 in the bead portion of a pneumatic tire is interposed between the bead core 11 and a toe guard 18, and the radially outer edge of each turnup portion being in contact with the main portion of the carcass ply and extending to an end point 0.5 to 4.0 inches (12.7 to 101.6 mm) radially outward of the bead core. The toe guard 18 has a first and second end and each end is disposed directly adjacent to the carcass ply. The first end 18a of the toe guard is located on the axially inner side of the main portion of the carcass ply at a location about 0.4 to 3.5 inches (10 to 89 mm) radially outward of the bead core and the second end 18b is located at a point ranging from substantially the axially outermost point of the bead core 11 to a location about 3.5 inches (89 mm) radially outward of the bead core. The first end 18a and second end 18b of the toe guard is a shorter distance from the bead core than the end point 12a of the turnup portion of the carcass ply.

Abstract: A method for manufacturing an annular carcass of a tire includes providing first and second ply materials, each including cords; winding at least a layer of the first ply material and a layer of the second ply material onto a carcass drum so the first ply material radially surrounds the second ply material; arranging two cables onto the cylindrical carcass preform; turning the part of the cylindrical carcass preform about the closer cable onto the part of the cylindrical carcass preform between the two cables; and expanding the cylindrical carcass preform to form an annular carcass having, in a bead area, inner and outer layers of the first ply material and inner and outer layers of the second ply material. The ply materials are arranged so the cords thereof are arranged cross-wise with respect to its neighboring ply materials or a neighboring ply material, considering the innermost or outermost layer.

Abstract: Tire having two beads having an annular reinforcing structure and a carcass reinforcement anchored in the two beads by a turn-up. Each bead has a bead rubber filler extending a radial distance from the radially innermost point of the annular reinforcing structure of the bead. The radial distance is not more than 10% of the tire's radial height. A sidewall has rigidifying metal reinforcing elements oriented along an angle not more than 10° to the circumferential direction and positioned with the distance between the radially innermost point of the annular reinforcing structure and the radially outer end of the rigidifying reinforcement between 20% and 40%, inclusive, of the tire's radial height and with the distance between the radially innermost point of the annular reinforcing structure and the radially inner end of the rigidifying reinforcement not more than 20% of the tire's radial height.
