A pneumatic rubber tire having an integral rubber innerliner containing anchored hollow glass microspheres.

Pneumatic tire having air retention innerliner containing anchored glass microspheres

A tire and method of building a tire is described wherein the tire has a carcass having a pair of sidewall plies and a bridge ply, each ply being reinforced with cords, the sidewall plies each having a first end which is received between the bridge ply and a belt reinforcing structure; wherein each sidewall ply extends axially outward along the sidewall and extending radially inwardly to the bead core and folded from a position axially outside the bead core to a position axially inside and around the bead core to an axially inner turnup end; said bridge ply having ends which overlap with a respective inner turnup end of said sidewall ply.

Tire with composite ply structure and envelope turnup

A tire carcass to be used with any type of tire is shown herein. A tire carcass includes a first ply portion, a second ply portion, each ply portion having an inner sidewall ply, an outer sidewall ply, a first end, a second end, and a bead core, a bridge portion, wherein the first ends of the ply portions are separated by the bridge portion, and at least two bridge plies, wherein the bridge plies span the bridge portion, wherein each of the bridge plies have a first end and a second end.

Multiple ply modular construction

The tire includes a first and second axially-spaced bead core, a carcass having at least one belt extending under a tread, and a first ply layer having first and second ends, a first end is located axially outside and adjacent a first bead core, and a second end that is located axially outside and adjacent a second bead core. The carcass further comprises first and second shoulder ply layers each shoulder ply layer having first and second ends, a first end is located under the tread belt, the shoulder ply extending down the side wall region with the second end folding from a position axially outside a respective bead core to a position axially inside and around the bead core. The carcass further comprises an additional reinforcement layer which wraps around the bead and is preferably positioned between the shoulder ply and the first ply layer, although not required.

Tire with turned down ply construction

This invention relates to a tire with a tread of a rubber composition which contains zinc rosinate within and on the surface of said rubber composition. Said zinc rosinate promotes enhanced wet traction for said tire tread by actually replacing a more conventional zinc stearate for a tire tread rubber composition. Said zinc rosinate is a product of a combination of rosin acid and zinc oxide formed in situ within said rubber composition. Said more conventional zinc stearate is a product of a combination of stearic acid and zinc oxide formed in situ within a tread rubber composition.

Tire with tread having enhanced wet traction

The invention relates to a tire having a lug and groove configured rubber tread having an outer rubber cap layer with a running surface and an underlying specialized transition rubber layer. The transition rubber layer is specialized in a sense of containing at least one of partially depolymerized rubber, particulate pre-cured rubber and coal dust. The outer tread cap layer is comprised of ground-contacting tread lugs with the tread running surface and associated tread grooves positioned between said tread lugs. The tread grooves may extend radially inward through the outer tread cap layer and, optionally, into the transition tread layer. The rubber tread configuration may also optionally also include a tread base rubber layer underlying the transition rubber layer.

The invention relates to a tire having a split ply carcass member with the ends of the split carcass ply spaced apart in the central crown portion of the tire and a central rubber layer spanning the gap between the split carcass ply ends, wherein said central rubber layer is reinforced with at least one of micro and macro reinforcing fillers. Said central rubber layer may additionally contain continuous cord reinforcement.

Tire tread

The invention relates to a tire with a tread which is quantitatively reinforced with silica where the tread is composed of three basic elastomers, namely, emulsion polymerization prepared styrene/butadiene rubber, cis 1,4-polybutadiene rubber and high vinyl polybutadiene rubber. Optionally, the basic elastomer composition can also contain a minor amount of cis 1,4-polyisoprene natural rubber.

Tire having silica reinforced tread

The invention relates to a tire with a tread which is quantitatively reinforced with silica where the tread is composed of three basic elastomers, namely, solution polymerization prepared styrene/butadiene rubber, cis 1,4-polybutadiene rubber and high vinyl polybutadiene rubber. Optionally the basic elastomer composition can also contain a minor amount of cis 1,4-polyisoprene natural rubber.

Tire with silica reinforced tread

The invention relates to a rubber tire composed of carbon black reinforced rubber carcass and having a rubber tread which is quantitatively reinforced with silica and contains a minor amount of carbon black reinforcement and/or carbon fibers. When said tread contains silica and carbon black reinforcement exclusive of carbon fibers, the said tread has a thin rubber layer over at least a portion of the outer surface tread intended to be ground-contacting wherein said rubber layer contains a combination of silica and/or carbon black reinforcement and carbon fibers. In one aspect, such alternative outer rubber layer (a) extends across at least a portion of the outer surface of the tread intended to be ground contacting and (b) contacts at least one other carbon black reinforced rubber component of the tire to provide a path of relatively low electrical resistance from said quantitatively silica reinforced tread to the bead portion of the tire carcass.

Tire having silica reinforced rubber tread containing carbon fibers

The subject invention relates to a technique for synthesizing rubbery copolymers of styrene and isoprene. These rubbery copolymers exhibit an excellent combination of properties for utilization in tire tread rubber compounds. By utilizing these styrene-isoprene rubbers in tire treads, tires having improved wet skid resistance can be built without sacrificing rolling resistance or tread wear characteristics. This invention more specifically discloses a process for the synthesis of styrene-isoprene rubbers which exhibit essentially a single glass transition temperature and which are particularly useful in tire tread rubber compounds, said process comprising copolymerizing a monomer mixture containing from about 2 weight percent to about 15 weight percent styrene monomer and from about 85 weight percent to about 98 weight percent isoprene monomer in an organic solvent in the presence of a catalyst system which is comprised of (a) a lithium initiator and (b) a modifier having the structural formula: ##STR1## wherein n represents an integer within the range of 3 to 6, wherein R represents an alkyl group containing from 1 to about 10 carbon atoms, and wherein the molar ratio of the modifier to the lithium initiator is within the range of 2:1 to 40:1.
