A wire wheel is provided in which some of the array of spokes extending between the hub and the rim penetrate the latter in the outboard bead seat. This bead seat is of smaller diameter than the inboard bead seat but is covered by a ribbon of a plastics material the outer diameter of which corresponds to the bead seat. The plastics ribbon is trapped in the channel of the outboard bead seat and seals the spoke holes penetrating the outboard bead seat. Nevertheless a metal step is exposed above the plastics ribbon for abutment by the toe of the outboard tire bead (not shown).

Wire wheels sealing structure

A tire and wheel rim assembly wherein the wheel rim includes adjacent to at least one bead seat a circumferentially extending groove and the tire bead has a radially and axially projecting extended toe portion which is axially and radially located within said groove. The toe is flexible in a direction substantially perpendicular to its length and substantially rigid in the direction of its length and provides an effective bead lock to retain the tire bead in position on the rim.

Tire and wheel rim assemblies

Tire deflation warning apparatus comprising a tubular housing having a sliding piston, a port in the housing for connection to the inflation chamber of the tire whereby the pressure of air in the tire at normal operating pressure can urge the piston to move relatively to the housing, biasing means associated with the piston in opposition to the air, and magnetic means operated by movement of the piston to actuate a warning switch.

Tire deflation warning apparatus

A wheel rim for a pneumatic tire having a pair of annular tire bead retaining flanges and a well located adjacent one of the flanges beneath the normal seating position of an associated tire bead. A well-filling ring can be located in the well to fill the well and provide support for the beads of a tire mounted on the rim.

Wheel rims and pneumatic tire and wheel rim assemblies

A wheel rim assembly comprising a rim having a well disposed between tire bead seats, a well cover band arranged to extend circumferentially around the well so as to prevent a tire bead from entering the well, the cover band being split at one side of its circumference, and a link of deformable material to connect the ends of the band, link having sufficient rigidity to hold the ends of the band against circumferential displacement relative to one another after deformation of the link to secure and tension the band around the well.

Wheel rim assemblies

A pneumatic tire and vehicle wheel assembly, the wheel being of the split-rim type without a tire mounting well in the base portion of the rim. A support member is provided extending radially fr0m the base portion of the rim to contact and support the tread region of the tire when the tire is wholly or partially deflated. The support member is preferably of L-section so as to have a cantilever flange to contact the tire and is preferably heat-conductive. A lubricant is preferably included in the tire cavity which will be between the tire and support member when the former contacts the latter. The support member is preferably adjacent one of the bead seats of the rim to serve the secondary purpose of retaining the tire bead on said seat. The support member may be an integral, radially outer part of the wheel disc or a separate, annular component surrounding the base portion of the rim.

Vehicle wheels

A divided or one piece wheel rim comprising two tire bead retaining flanges with inclined bead seating portions and a substantially flat well base portion positioned therebetween. A radially inwardly tapering groove being provided adjacent the toe portion of an associated tire bead.
