ABSTRACT:
The drawings disclose a pneumatic tubeless tire including either one or two load support running bands adapted to support the weight of a vehicle should the tire become deflated. The circumferential centers of the support bands are substantially coplanar with the planes of respective annular tire beads. In one embodiment the applicable bead is a third bead integrally formed adjacent one of the normal beads on the inner surface of the beaded edge of the tire. Double rows of circumferentially oriented, spaced apart tension spokes, with alternate pairs thereof oppositely angularly disposed so as to cross one another, rigidly connect each support band to the respective annular bead. An annular ridge is formed on the rim adjacent the inner edge of each beaded end to retain the beaded ends in position during deflated tire conditions.
