Racing wheel

A wheel is provided that combines the principles of a beadlock wheel and a liner wheel for improved performance in motor racing, in particular drag racing. The wheel has beadlock rings that fasten to inner and outer rims of the wheel to secure an outer tire, and the wheel has knurls interior to the inner and outer rims to secure an inner tire. Projections from the inner and outer rims are arranged to accommodate the various functions of the combination of the beadlock rings and the inner tire. The projections counterintuitively add weight to the wheel, yet the combination of beadlock rings and an inner tire results in improved stability and safety as well as faster times on the racetrack.

VEHICLE WHEEL RIM

A vehicle wheel rim made of a metal sheet has a transition section adjacent to an inner well flank and to an inner retaining hump between the transition section and an inner rim shoulder. The inner retaining hump is rotationally symmetrical with respect to a wheel axis. The transition section has at least one stiffening formation arranged on the transition section, the stiffening formation being, on a first radial side of the vehicle wheel rim, radially protruding with respect to an adjacent area of the transition section and, on a second radial side of the vehicle wheel rim, radially recessed with respect to the adjacent area of the transition section. The at least one stiffening formation has a wall thickness substantially equal to a wall thickness of the adjacent area of the transition section that has a radial sectional profile varying along a circumferential direction of a vehicle wheel.

SPLIT BEAD SEAT PROTECTOR

An integral alloy vehicle wheel is provided with a replaceable bead seat protector that protects the bead seat portion of the wheel from tire abrasion and subsequent corrosion. The bead seat protector has a split body to aid in mounting the protector over the outer flanges of the vehicle wheel.
