Pneumatic tire having structural ribs
Abstract:
A vehicle wheel and tire combination is disclosed herein having a wheel with a central hub provided with attachment holes for receiving wheel studs from a driving wheel drum. The periphery of the wheel hub is provided with an outwardly projecting V shaped integral flange or rim supporting a plurality of loops, spokes or braces arranged in spatial relationship about the entire circumference of the wheel hub flange. A rubber or the like tire casing is carried over the plurality of loops or braces and the terminating edges of the tire casing are vulcanized or otherwise bonded to the recepticles provided in flange so as to enclose or encase the spokes. Steel belting is carried on the underside of the tire casing and the opposite sides of the belting are captured in annular recesses adjacent to and parallel with the recepticle holding the casing edge. Bands are employed to retain the belting in the recess and the assembly of casing and belting are vulcanized together. Air is captured between the hub flange and inside surfaces of the tire casing and belting combination so as to provide a soft vehicle tire reinforced by the loops, spokes or braces.
