A solid monolithic tire for use on a wheel rim can be improved by incorporating within the tire a circumferentially extending tunnel formed on the inside of the tire body. Further, the tire body has inclined side walls that converge outwardly to form a V-shaped cross section. The apex of this V-shaped cross section forms the tread portion of the tire. Each of the side walls of the tire terminate in a thickened portion (22,24) which forms a bead shoulder (26,28) capable of seating on the bead flanges of the wheel rim to which the tire is mounted. Extending down through the thickened portion of either side of the tire is a bead (30,32) which has a lower bead wall on the portion most distal to the thickened portion. A bead cord (46,48) extends circumferentially embedded within the bead near the lower bead wall. The process by which the the tire is formed allows the bead cord to be positioned in its appropriate place within the bead. During this process the bead cord is actively positioned within a mold and the material from which the tire is prepared is injected into the mold surrounding the bead cord. |
