Abstract
A radial ply tire and rim assembly in which the rim has an axially extended flange with a special configuration to provide a double register for the bead area. The tire when mounted on the rim and inflated has its carcass distorted radially outwardly from the natural equilibrium curvature in which it was molded and the carcass curves axially inwardly to meet the bead core at a very small angle with respect to the axis of the tire.
Claims11
In a radial ply pneumatic tire and rim assembly;
- a. a rim including a pair of spaced annular bead seat surfaces, a first annular register surface extending generally radially outwardly from the axially outer edge of each bead seat surface, and an annular stabilizer flange surface extending generally axially outwardly from the radially outer edge of each said first annular register surface;
- b. a pneumatic tire of the open-bellied type having a tread portion, a pair of sidewall portions, a pair of axially spaced apart bead portions each having an annular inextensible bead core, a carcass structure of inextensible cords extending continuously from one bead core to the other bead core and having a neutral contour line, and a circumferentially extending belt structure disposed circumferentially about said carcass ply;
- and
- c. a second annular register surface extending from the axially outer edge of said stabilizer flange surface and having an arcuate configuration such that the spacing between said carcass structure and the rim is substantially constant in the area of the stabilizer flange surface and is less in the area of the second bead register surface than in the area of the stabilizer flange surface.
