Abstract
An integral tire and rim assembly in which the tire is built and cured on the rim. The tire is a closed torus crown over-lap type having a pair of annular inextensible beads. The rim is an annular and axially continuous unitary rigid member with flanges that extend radially outwardly beyond the minimum diameter of the inextensible bead cores. A run-flat device is included in the tire cavity.
Claims17
An integral pneumatic tire and rim assembly in which said tire is of a closed torus contruction and has at least one carcass ply that is joined in the tread area to provide a circumferential splice, a circumferentially extending tread portion, said splice disposed centrally in said tread portion of said tire, a radial inner wall engaging the rim and a pair of sidewalls connecting the respective axial outer edges of the tread and radial inner wall;
- and said rim is an annular unitary rigid member, said assembly being further characterized by an annular unitary rigid means disposed in the cavity of a tire adjacent said radial inner wall, said annular unitary rigid means having a clamping member, an annular support member which extends circumferentially about said tire and radially outward of said clamping member and a generally cylindrical support member for supporting the tread when the tire is run in an uninflated condition and means extending between and connecting said clamping member and said rim to clamp said tire on said rim.
An integral tire and rim assembly in which said tire is of a closed torus construction having carcass plies that are joined in the tread area to provide a circumferential splice, a circumferentially extending tread portion, said splice disposed centrally within said tread portion of said tire, a radial inner wall and a pair of sidewalls connecting the axial outer edges of said tread portion and radial inner wall and having a pair of inextensible bead cores disposed adjacent the axial outer edges of the inside wall of said radially inner wall;
- and said rim is an annular unitary rigid member of a flate base construction having flanges disposed at its axial outer edges and axially outwardly of the pair of bead cores, said flanges having a larger diameter than the minimum diameter of said inextensible bead cores, a pair of annular removable flange extensions are disposed axially outward of said pair of flanges and are of a configuration which conforms to the radially inner sidewalls of the tire to provide lateral rigidity to the structure.
