Abstract:
The present invention is directed to a pneumatic tire comprising at least one component, the at least one component comprising a rubber composition contacting one or more reinforcing polyester cords, the polyester cords comprising an RFL adhesive disposed on the surface of the polyester cords, the RFL adhesive comprising from 1 to 20 weight percent of a presilanized silica.
Abstract:
A pneumatic tire has a single carcass ply, at least one belt ply disposed radially outward of the carcass ply in a crown portion of the tire, and at least one insert located adjacent the carcass ply in a sidewall portion, the insert providing support for the tire load to enable the tire to operate in underinflated conditions. The carcass ply is comprised of at least one composite cord. The composite cord is formed of at least two first yarns twisted helically about at least one second yarn. The first yarns and the second yarn having different modulus of elasticity, the first yarns having a modulus greater than the modulus of the second yarn.
Abstract:
A pneumatic tire includes a carcass reinforced by a carcass ply, at least one belt ply disposed radially outward of the carcass ply in a crown portion of the pneumatic tire, and at least one insert located adjacent the carcass ply in a sidewall portion of the carcass. The insert provides support for the tire load to enable the pneumatic tire to operate under extreme conditions. The carcass ply comprises at least one composite cord having a first core yarn with a second outer yarn and an outer metallic filament both wrapped around the first core yarn such that the first core yarn has a modulus less than a combined modulus of the second outer yarn and the outer metallic filament.
Abstract:
A pneumatic tire includes an axis of rotation, a carcass, a tread, and a belt structure. The carcass has at least one reinforced ply and a reinforcing structure providing a buffer for absorbing shear strain. The tread is disposed radially outward of the carcass. The belt structure is disposed radially between the carcass and the tread. The reinforcing structure comprises at least one layer of an open construction LENO weave fabric having warp yarns extending in the radial direction and weft yarns extending in the circumferential direction.
Abstract:
A pneumatic tire includes a radial ply carcass, a tread portion disposed radially outward of the carcass, and a crown reinforcing structure interposed between the tread portion and the carcass in circumferential relation to the carcass. The crown reinforcing structure includes a belt assembly having at least one belt ply with reinforcement cords extending parallel to one another and an overlay structure including a nylon reinforced layer extending transversely over the belt assembly and making an angle of between −5 degrees and +5 degrees with an equatorial plane of the tire. The nylon reinforced layer includes nylon cords having a 2000-2200/1 Dtex, 1-10 TPI construction with an end density of 10-35 EPI.
Abstract:
A pneumatic tire has an axis of rotation. The pneumatic tire includes a reinforced ply placed in a predetermined location on a toroidal surface, a tread disposed radially outward of the reinforced ply, and a belt structure disposed radially between the reinforced ply and the tread. The reinforced ply includes at least one layer of an open construction woven or knitted fabric having warp yarns extending in a circumferential direction and weft yarns extending in a radial direction.
Abstract:
A pneumatic tire has an axis of rotation. The pneumatic tire includes a carcass having at least one reinforced ply and a reinforcing structure proximal to a bead region of the pneumatic tire, a tread disposed radially outward of the carcass, and a belt structure disposed radially between the carcass and the tread. The reinforcing structure includes at least one layer of an open construction woven or knitted fabric having warp yarns extending in a circumferential direction and weft yarns of the carcass ply extending in a radial direction.
Abstract:
A pneumatic tire includes an axis of rotation, a carcass, a tread, and a belt structure. The carcass has at least one reinforced ply and a reinforcing structure for absorbing shear strain. The tread is disposed radially outward of the carcass. The belt structure is disposed radially between the carcass and the tread. The reinforcing structure of the carcass comprises a fabric of cords. Each cord has at least one strand of twisted polyketone yarn. The twisted polyketone yarn has a linear density from 1570 dtex to 1770 dtex and a twist level from 3 TPI to 9 TPI. The cords have a twist level from 3 TPI to 9 TPI and a twist direction opposite to a twist direction of the polyketone yarns.

Abstract:
A pneumatic radial runflat tire includes a pair of parallel annular beads, a carcass ply structure, a belt reinforcement structure, a tread, and a pair of sidewalls. The carcass ply structure comprises a polyester fabric with a cord construction of 2200 dtex/2 8.5/8.5 tpi with a cord density of between 16 and 28 epi. The belt reinforcement structure is disposed radially outward of the carcass ply structure in a crown area of the tire. The tread is disposed radially outward of the belt reinforcement structure. The pair of sidewalls comprise part of the carcass ply structure. The pair of sidewalls is disposed between the tread and the pair of parallel annular beads.
