摘要:
A pneumatic tire comprising a tread (12) and a carcass (22) having at least one reinforced ply (14) is disclosed. The reinforced ply comprises a reinforcing structure (141) comprising at least one layer (300) of an open construction woven or knitted fabric having warp yarns (311) extending in a first direction and weft yarns (312) of the reinforced ply (14) extending in the radial direction or at least substantially in the radial direction.

The present invention is directed to a pneumatic tire (10) including at least one component. The component includes a rubber composition. The rubber composition includes a diene based elastomer and from 1 to 100 parts by weight of a metallized organic short fiber, per 100 parts by weight of elastomer. The organic short fibers having a length from 1 mm to 5 mm. Preferably, both the length and the ends of the short fibers are completely coated with a layer of metal or metal alloy.

A pneumatic tire comprises a carcass (12), a tread (19) disposed radially outward of the carcass (12) and a crown reinforcing structure (14) interposed between the tread (19) and the carcass (12) in circumferential relation to the carcass (12). The crown reinforcing structure (14) includes a belt assembly having at least one belt ply (15, 16) with reinforcement cords extending parallel to one another and an overlay structure (18) including an aliphatic polyamide reinforced layer. The aliphatic polyamide reinforced layer makes an angle of between -5 degrees and +5 degrees with an equatorial plane (EP) of the tire (10), the aliphatic polyamide reinforced layer including aliphatic polyamide cords having a 1900/1 to 3000/1 Dtex, 1 to 10 turns per 2.54 cm cord construction.

The present invention is directed to a pneumatic tire comprising at least one component, the at least one component comprising a rubber composition, the rubber composition comprising a diene based elastomer and from 1 to 100 parts by weight, per 100 parts by weight of elastomer (phr), of a polyketone fiber having a length ranging from 0.5 to 20 mm and preferably having a weight ranging from 0.5 to 5 decitex, and from 1 to 30 phr of an epoxidized polyisoprene having a number-average molecular weight of 5000 to 100000.
摘要:
The pneumatic tire (20) includes a carcass (21) having at least one reinforced ply, a tread (32) disposed radially outward of the carcass (21), and a belt structure (28) disposed radially between the carcass (21) and the tread (32). The belt structure (28) includes cords of at least three strands of twisted polyketone yarn. The twisted polyketone yarn has a linear density from 1570 dtex to 1770 dtex and a twist level from 3.0 TPI to 8.0 TPI. The cords have a twist level from 3.0 TPI to 8.0 TPI and a twist direction opposite to a twist direction the polyketone yarn.

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.
摘要:
A pneumatic tire (10) has a single carcass ply (12), at least one belt ply (24) disposed radially outward of the carcass ply in a crown portion of the tire, and at least one insert (20) located adjacent the carcass ply (14) in a sidewall portion, the insert providing support for the tire load to enable the tire to operate in underinflated conditions. The carcass ply comprises at least one composite cord (30). 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 (34) having a modulus greater than the modulus of the second yarn (32).
摘要:
The present invention is directed to a runflat tire (10) having at least one of its components comprising the radial carcass ply (22), the underlay, the overlay, the bead inserts or the chippers, reinforced with polyester cords having a polyepoxide disposed on its surface. The polyester cord is formed by first obtaining a cord through twisting together a plurality of polyester yarns, secondly treating the cord with an aqueous dispersion comprising a polyepoxide, and optionally thirdly treating the cord with an aqueous RFL dispersion comprising a resorcinol-formaldehyde resin, a styrene-butadiene copolymer latex, a vinylpyridine-styrene-butadiene terpolymer latex, and a blocked isocyanate. The inventions also directed to such a cord and to a method to make such a cord.
