Abstract

Parent patent described tyre designs with unreinforced concave sidewalls functioning in compression while the tyre is inflated. Here, such tyres have bead profiles which can be located in a channel at the boundary of the wheel rim, then positively trapped by compression between its seat on the wheel and an inextensible annular clamp having a slightly smaller dia. than the outermost flange of the wheel rim. Pref. the annular clamp is either a metal profile or a cable of twisted metal filaments, esp. clad in a matrix of a rubber at least as hard as the tyre bead grade and profiled to engage with a groove or lip in or bounding the beading surface. Positive clamping prevents dislocation of the tyre from the wheel if deflated due to a puncture.
