ABSTRACT:
A tire having a pair of axially spaced-apart bead regions each reinforced by an annular bead hoop around which one edge of a carcass reinforcing ply is wrapped and a filler strip positioned in the axially outer region of the bead. The filter strip which extends circumferentially around the bead, has one edge radially inwards of the bead hoop and one edge axially outwards of the bead hoop characterized in that the filler strips in both beads have their cords laid at an angle to the same specified direction circumferentially such that the cords of one filler strip are substantially parallel to the cords of the other filler strip. The tire has an external direction marker in the same circumferential direction to the specified direction so that in use the tire may be fitted to a vehicle with the marker in the opposite direction to the greatest torque force from the wheel. The filler strip may be cut edge tire cord fabric or a single cord laid in a zig-zag to form the fabric.
