Abstract
A pneumatic tire and wheel rim assembly is disclosed in which the rim bead seats are defined by grooves having radially directed side portions which retain the associated tire bead against movement in an axial direction and each rim bead seat includes means in engagement with the tire bead to restrict rotation of the tire bead relative to the bead seat. Preferably said means comprises a plurality of projections formed integrally with part or all of the grooves which engage the associated tire bead to restrict rotation. Each projection may comprise a circumferentially extending rib or a tooth.
Claims13
A pneumatic tire and wheel rim assembly comprising:
- a tire having a reinforced tread portion, a pair of sidewalls and a pair of axially spaced tire beads each with a substantially inextensible bead reinforcement;
- a wheel rim having a pair of axially spaced bead seats defined by grooves in each of which a respective one of said tire beads is located, each groove comprising a base portion and a pair of opposed side portions which extend in a generally radially outwards direction from said base portion;
- said reinforced tire tread portion having an axial width greater than the axial distance between the axially outer side portions of said grooves;
- each of said side portions projecting radially outwards beyond the radially inner surface of the adjacent inextensible bead reinforcement whereby each tire bead is retained against movement in an axial direction, each rim bead seat having means in engagement with the associated tire bead to restrict rotation of said tire bead relative to said rim bead seat.
