Abstract
Abstract A lockring which fits between the rimbase and removable bead seat band of the rim for a large pneumatic tire and having surfaces mating with surfaces of the bead seat band and rimbase disposed at angles with which result in great frictional contact when the tire is inflated. This produces a wedging effect and eliminates the need for ''''drivers'''' which are interengaging lugs on the rimbase and removable bead seat band to prevent relative rotation of these parts.

Claim 1
Independent Claim
209 words
A multiple-piece tire rim assembly for mounting large diameter, wide-base tire means subject to high-torque loading during use comprising; an annular one-piece rimbase means, said rimbase means having a fixed, tire-bead-retaining annular flange means mounted upon one axial end thereof and an axially moveable, tire-bead-retaining annular flange means mounted upon the other axial end thereof, said axially movable flange means having an annular surface means which is inclined at a predetermined angle of between 24* and 30* with respect to the axis of said annular rimbase means, a split-ring locking means mounted upon said other axial end of said rimbase means, said locking means having surface means which coact with said annular surface means when a tire means is operatively mounted upon said tire rim assembly, annular groove means in said rimbase means having sidewalls tapering axially inwardly toward each other and inclined with respect to a line normal to said axis of said annular rimbase means at said predetermined angle, said locking means also having complementary taper portions which engage each of said sidewalls a locking effect and to prevent any relative tangential movement between said movable flange means, said locking means, and said rim base means when said tire rim assembly is under high-torque loading during use.
