Abstract
Abstract Sealing means for a pneumatic tire and wheel rim assembly in which the wheel rim has a pair of axially spaced bead seats defined by grooves in each of which a respective one of a pair of axially spaced tire beads is located and retained. The sealing means comprises two seal elements each having a resiliently deformable portion which acts between confronting axially directed surfaces of the associated tire bead and bead seat to facilitate assembly and subsequently hold the tire bead under compression in an axial direction to prevent the tire bead slipping relative to the wheel rim.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
99 words
A pneumatic tire and wheel rim assembly in which said rim has a pair of axially spaced bead seats defined by grooves in each of which a respective one of a pair of substantially inextensible axially spaced tire beads is located and retained and sealing means comprising a pair of elastomeric seal elements each of which acts between a respective one of said tire beads and the associated groove whereby each tire bead is held under compression in an axial direction in the associated groove so that the seal elements seal the beads to the rim by axial compression.
Claim 2
Dependent Claim
99 words
A pneumatic tire and wheel rim assembly in which said rim has a pair of axially spaced bead seats defined by grooves in each of which a respective one of a pair of substantially inextensible axially spaced tire beads is located and retained and sealing means comprising a pair of elastomeric seal elements each of which acts between a respective one of said tire beads and the associated groove whereby each tire bead is held under compression in an axial direction in the associated groove so that the seal elements seal the beads to the rim by axial compression.
Claim 3
Dependent Claim
35 words
An assembly according to claim 1 wherein each seal element has a resiliently deformable portion which acts between an axially inwardly and/or an axially outwardly directed surface of said tire bead and the associated groove.
Claim 4
Dependent Claim
30 words
An assembly according to claim 1 wherein each seal element is of generally channel section so as to embrace said tire bead and provide a lining for the associated groove.
Claim 5
Dependent Claim
29 words
An assembly according to claim 1 wherein each seal element has an axially and radially outwardly tapered portion which seats against the lower region of the adjacent tire sidewall.
Claim 6
Dependent Claim
44 words
An assembly according to claim 1 wherein each seal element is defined by the lateral edge portions of a seal member which extends circumferentially around the radially outer surface of said rim and across the axial width of said rim between said bead seats.
Claim 7
Dependent Claim
33 words
An assembly according to claim 1 wherein each tire bead has a bead reinforcement and the diameter of said bead reinforcement is less than the maximum diameter of the associated groove side portions.
Claim 8
Dependent Claim
13 words
An assembly according to claim 1 wherein the rim is multi-component and well-less.
Claim 9
Dependent Claim
23 words
An assembly according to claim 1 wherein said tyre is selected from the group consisting of a radial, cross-ply and belted bias tire.
