Abstract: A die for a polymer mixing machine includes first and second opposing surfaces. Each defines first cylindrical portions and second V-shaped portions interspaced between each first portion. The first and second opposing surfaces produce a ply with first portions thicker than second portions and throated portions therebetween.

Abstract: A tire includes a pair of axially spaced apart annular bead cores, a carcass ply extending around both bead cores, a tread for engaging a contact surface and being disposed radially outward of the carcass ply, and a belt structure disposed radially between the carcass ply and the tread. The carcass ply includes a plurality of cords embedded in a polymer matrix. The carcass ply has a first radially upper surface and a second radially lower surface disposed opposite the first surface. The first surface defines first portions and second portions interspaced between each first portion. Each first portion has a thickness greater than each second portion thereby forming throated portions between each cord of the plurality of cords.
