<p>A pneumatic tyre and wheel assembly (10) particularly suitable for heavy duty use to replace a side-by-side pair of coaxial tyres comprises a flexible reinforced partition wall (17) which extends between the tyre tread region (15) and a third bead region (16) disposed between the bead regions (13) of the sidewalls (14). The third bead region (16) is dimensioned to seal against a wheel rim (11) such that the resulting tyre and wheel assembly (10) may comprise two independently pressurisable chambers (25, 26). Forces tending to deform the tyre either radially or transversely will place an upper part of the partition wall (17) in tension, tending to maintain the shape of the tyre. By this arrangement the need for heavy, stiff sidewalls (14) is avoided.</p> |
