A tire filler comprises elongated strips of high density foam rubber pre-cured in flat moulds and have transverse cross-sectional contours such as will conform when one of a set of the same, to fit snugly against the interior surrounding surface of the associated tire carcass in virtue of the elongated side-edge of each strip being formed in angular relationship to the opposite elongated face-surface of each strip to facilitate snug fittment with one another and the tire casing carcass inner wall, The filler is dimensioned to 'overfill' the carcass of the tire casing and the filler is installed by first spreading apart the opposite side walls of the carcass, The filler is inserted into the casing in concentric layers such that the pre-dimensioned elongated side-edges of each adjacent strip or layer are in substantially smooth co-term inous relationship against said interior surrounding tire carcass surface. When the walls are released the casing hold a spread-apart mode until they are pressed together on installation of the combination on a rim thereby packing the layers into the casing to create a wheel and tire combination pressurized for load bearing capability. |
