A pneumatic tire having a carcass and a belt reinforcing structure, the belt reinforcing structure comprising: a zigzag belt reinforcing structure formed of a strip of reinforcement cords, the strip of reinforcement cords being inclined at 5 to 30 degrees relative to the centerplane of the tire extending in alternation to turnaround points at each lateral edge, wherein the strip of cords is formed from two different cords made of different materials.

Reduced weight aircraft tire

A pneumatic tire having a carcass and a belt reinforcing structure, the belt reinforcing structure comprising: a zigzag belt reinforcing structure formed of a strip of one or more reinforcement cords, the strip of one or more reinforcement cords being inclined at 5 to 30 degrees relative to the centerplane of the tire extending in alternation to turnaround points at each lateral edge, wherein the zigzag strip of cords is formed from two different reinforcement cords made of different materials, and a low angle belt of the tire has a higher EPI than the zigzag belt.

Balance pads for balancing pneumatic tires having DVA innerliners, and methods for balancing such pneumatic tires, are disclosed. In one embodiment, a balance pad is provided for balancing a pneumatic tire having a DVA innerliner. The balance pad includes an outer layer having a dynamically vulcanized alloy, which comprises an engineering resin as a continuous phase and at least a partially vulcanized rubber as a dispersed phase. The balance pad further includes an inner layer having a rubber or plastic compound that is bonded to the outer layer. The outer layer is capable of being bonded to an inner surface of a tire innerliner, which includes a dynamically vulcanized alloy having an engineering resin as a continuous phase and at least a partially vulcanized rubber as a dispersed phase.

Balance pads for balancing pneumatic tires

The invention relates to a tire having a rubber tread comprised of cap/base construction where the tread cap layer provides the running surface of the tread and the tread base layer underlies the tread cap layer and thereby provides a transition between the tread cap layer and the tire carcass. For this invention, the tread cap layer is comprised of a plurality of individual circumferential load-bearing zones of rubber compositions, which exhibit graduated physical properties, and which extend from the outer running surface of the tread cap layer radially inward to said tread base layer. In one aspect, the zoned rubber tread cap layer and rubber tread base layer are co-extruded together to form a unit as an integral tread rubber composite.

A pneumatic tire has a pair of shoulder portions extending between a tread portion and opposed sidewall portions. The tire has at least one ply of a composite fabric. The composite fabric has three layers with the middle layer comprising a plurality of straight warp yarns wherein the three layers are bound together with binder yarns. At a minimum, the composite fabric ply is located in the tire shoulders.

This invention relates to a pneumatic tire having a built-in non-black colored sealant layer and its preparation. The sealant layer is derived from a sealant precursor layer comprised of a butyl rubber, organoperoxide, particulate, synthetic amorphous silica and plant-derived organic agricultural seed flour, together with a non-black colored colorant. The butyl rubber-based sealant precursor layer is build into the tire to form a tire assembly and the butyl rubber component of the sealant precursor layer is depolymerized during a subsequent curing of the tire at an elevated temperature in a suitable mold to form the tire having the resultant built-in sealant. The particulate plant derived organic agricultural seed flour is a renewable raw material in a sense that it can be replenished in nature and therefore not as a significant depletion of non-renewable natural resource. The agricultural plant seed flour is comprised of at least a portion of a ground plant seed (e.g. whole or partial seed portion including for example its nucleus and/or shell) of an agricultural seed producing plant such as, for example, wheat, rye, rice, barley, oat, mullet, soybean and/or corn. The sealant layer may also contain one or more of a liquid polyisoprene and short organic fibers. Preferably, the amorphous silica is a precipitated silica, namely aggregates of primary silica particles.

Pneumatic tire having built-in colored sealant layer and preparation thereof

This invention relates to a pneumatic tire having a built-in sealant layer and its preparation. The sealant layer precursor is a layer of a butyl rubber based composition which contains an organoperoxide. The butyl rubber of said precursor is a copolymer of isobutylene and isoprene containing from about 0.5 to about 5, alternately less than 1, mole percent isoprene. The precursor composition contains carbon black and/or coal dust and may contain a dispersion of liquid conjugated diene polymer (e.g. liquid cis 1,4-polyisoprene polymer), short fibers and/or hollow glass microspheres. A layer of the sealant precursor is built into the tire between a sulfur vulcanized halobutyl rubber innerliner and conjugated diene-based rubber of the tire carcass. The butyl rubber of the sealant precursor is partially depolymerized by the organoperoxide during the elevated temperature vulcanization of the tire to form the built-in sealant layer. In one aspect of the invention, said uncured butyl rubber sealant precursor layer composition has a storage modulus G' (80&#xb0; C.) in a range of about 100 to about 400 kPa and said partially depolymerized butyl rubber sealant layer composition has a storage modulus G&#x2032; (80&#xb0; C.) in range of about 5 to about 50 kPa.

The present invention relates to a tire with a carcass ply and/or circumferential carcass belt component comprised of a natural rubber-rich diene-based rubber composition which contains a dispersion of precipitated silica reinforcement, with coupling agent, to a substantial exclusion of carbon black.
