ABSTRACT:
A pneumatic tire having a tread, a pair of sidewalls each terminating in an annular bead area, and a pair of beads located within the bead areas, for mounting the tire on a rim. Each of the beads is formed by at least one strand of metallic wire wound upon itself into a spiral and terminating in inner and outer ends, which ends circumferentially overlap each other. The beads are placed in the tire so that the spiral orientation of the beads are opposite to each other and the inner ends of the beads are in substantial axial alignment to reduce radial force variations on the tire.
