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×D+4400 MPa) ×95%, where D is the filament diameter in millimeters. The turnup portion of the single carcass ply in the bead portion of a pneumatic tire is interposed between the bead core and a toe guard , 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 has a first and second end and each end is disposed directly adjacent to the carcass ply. The first end 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 is located at a point ranging from substantially the axially outermost point of the bead core to a location about 3.5 inches (89 mm) radially outward of the bead core. The first end and second end of the toe guard is a shorter distance from the bead core than the end point of the turnup portion of the carcass ply.
