Abstract
Abstract A tire construction featuring a carcass composed off radially disposed cords, each composed of a multiplicity of continuous glass filaments, a pair of tread reinforcing belts featuring parallel cords of glass, each composed of a multiplicity of glass filaments, and, in combination therewith, a liner ply extending from bead to bead on the innerside of said carcass, said liner ply containing a minor amount of chopped lengths of glass and a squeegee or cushion ply containing a minor amount of chopped lengths of glass interposed between the liner ply and the radial cord carcass ply in the tread region extending from one shoulder to the opposite shoulder.
