Abstract
A wheel rim construction that cooperates with the tire bead seat to insure retention of the tire, even under a 'run flat' condition. The bead seat portion of the rim is formed with a plurality of circumferentially extending radial projections that cause gripping of the tire bead to form a mechanical interlock between the projections and wheel flange. The radial projections are formed during the roll forming of the wheel rim by extruding the rim material into grooves in the upper finishing roll so that the permanently formed projections lie radially outward of the basic rim profile.
