Abstract

1491005 Pneumatic tyre and wheel rim assemblies TOYO RUBBER INDUSTRY CO Ltd 12 Nov 1974 [14 Nov 1973] 49008/74 Heading B7C In a pneumatic tyre and wheel rim assembly the tyre 4 has an annular projection 9 located adjacent a tyre bead retaining flange 6 of the rim 8 so as to project axially beyond the flange and radially inwardly of the radially outer extremity of the flange, when the tyre is not inflated and is under no load the half-difference # between the minimum diameter D of the projection 9 and the maximum external diameter D 0 of the flange 6 being 2-7 mm., and the projection 9 being reinforced by a circumferentially extending reinforcement and having a rigid portion formed of a rubber compound with a modolus of elasticity at 100% elongation of 30-70 kg./cm.<SP>2</SP>. The tyre may as shown have two projections 9 located adjacent respective flanges 6, and the external surface of each projection may be curved with a radius of curvature R of 4-30 mm. The tyre may be constructed such that an angle #, Fig. 1, lies between 45 and 90 degrees. Each projection may, as shown in Fig. 4, be reinforced by a core 12 of steel wires embedded in a member 16 of the above-mentioned rubber compound interposed between radial carcass plies 10, 11 of the tyre, and by a chafer strip 13 extending from the adjacent tyre bead. In a modification of the Fig. 4 construction the core 12 is omitted and the rubber member between the plies 10, 11 is extended to the adjacent bead wire 15, and a further rubber member on the external surface of the projection covers the radially outer part of the chafer strip 13. Each projection may alternatively have a reinforcement of fibre reinforced plastics or circumferentially oriented fibres.
