Abstract
Abstract A pneumatic tire vehicle wheel which is employable for emergency running or operation. The unitary or one-piece rim with slanted, inclined or cylindrical rim shoulder and rim flange is provided with an emergency running or operating support which is constructed radially elevated in a cap-like configuration. The tire beads are constructed turnable or rotatable around the bead core and are capable of being shifted or displaced in an eccentric manner upon the rim. The round or square bead core lies upon a radial height or level of at least 0.4× the rim flange height in the tire bead. A method for assembling or putting together of a pneumatic tire-vehicle wheel includes the steps of moving the rim and the pneumatic tire with axially outwardly turned or rotated tire beads relatively into each other until a first tire bead is located upon a first rim shoulder; then there is further moving of the rim and pneumatic tire relatively into each other; there is moving of the tire bead over the cap-like rim support until the tire bead is located upon the second rim shoulder; thereafter the further tire bead and the rim are moved relatively into each other until the tire bead is located upon the rim shoulder; then there is shifting or displacing of the tire beads with pumped-in compressed or pressurized air under the rising or building-up interior pressure out of the turned or rotated built-in position upon the rim eccentrically into the clamping position with the rim.
