The invention relates to a pneumatic tire comprising a carcass and a tread located radially outward of the carcass and extending between the tire sidewalls; the tread providing a radially outermost tread running surface; the tread comprising a first tread layer comprising a first rubber compound and a second tread layer comprising a second rubber compound; wherein the second tread layer is located radially adjacent to the first tread layer; wherein the first rubber compound is compositionally distinct from the second rubber compound; wherein the second tread layer comprises one or more integrally formed extensions of the second tread layer extending radially outwardly toward the tread running surface; wherein each of the integrally formed extensions of the second tread layer comprises a circumferentially continuous groove and a reinforcement zone disposed on a side of the groove; wherein the first rubber compound comprises 100 parts by weight of at least one diene based elastomer, and from 1 to 150 phr of silica; and the second rubber compound comprises a diene base elastomer, from 50 to 120 phr of a filler, wherein at least 20 phr of the filler is a high surface area carbon black having an iodine adsorption number of at least 100 g/kg, from 1 to 45 phr of a methylene acceptor, from 1 to 25 phr of a methylene donor, and from 1 to 30 phr of at least one additive selected from the group consisting of carbamic resins, liquid diene based polymers having a number average molecular weight ranging from 1000 to 25000, and aromatic hydrocarbon resins.

Pneumatic tire having a dual layer tread

A mixing and extrusion machine for tire sealant materials of the type comprising: a dump extruder equipped with conical converging twin screws located in a batching chamber, said chamber having a low pressure feeding area and a high pressure ducted area; a removable blind flange for temporarily sealing the outlet of said batching chamber so that said material is forced to recirculate between said duct area and said feeding area within said batching chamber, said chamber thereby also acting as a compounding chamber; and an inlet port located in the high pressure ducted area, the inlet port capable of introducing a diluent during mixing of a tire sealant material.

Modified tire sealant mixing device

A pneumatic tire includes a reinforcing ply structure extending between a pair of bead portions, a pair of sidewalls, each sidewall located radially outward of one of the pair of bead portions, a tread radially outward from the reinforcing ply structure, a belt reinforcing structure located radially outward from the reinforcing ply structure and radially inward from the tread, and an innerliner structure extending along an inner surface of the reinforcing ply from a position adjacent one bead portion to a position adjacent the other bead portion. The innerliner structure includes multiple alternating layers of rubber compound and sealant.

Pneumatic tire with sealant layer

A pneumatic tire assembly includes: a tire having a pneumatic cavity; a rigid structure for facilitating operation of the tire assembly, the rigid structure being bonded to the tire by a layered thermoplastic material such that a stiffness gradient is created between the structure and the tire; first and second sidewalls extending respectively from first and second tire bead regions to a tire tread region, the first sidewall having at least one bending region operatively bending when radially within a rolling tire footprint; and a sidewall groove defined by groove walls positioned within the bending region of the first tire sidewall, the sidewall groove deforming segment by segment between a non-deformed state and a deformed, constricted state in response to bending of the bending region of the first sidewall while radially within the rolling tire footprint.

Bonding to a pneumatic tire

The invention relates to the preparation of a rubber composition containing a pre-treated precipitated silica and a tire having a component comprised of such rubber composition. The pre-treated silica is a precipitated silica having been pre-treated with a silica coupling agent comprised of an alkoxyorganomercaptosilane to form a precipitated silica/coupling agent composite prior to its blending with a rubber composition. The rubber composition preparation involves reacting said pretreated silica/coupling agent composite with a combination of bis(3-triethoxysilylpropyl) polysulfides in situ within the rubber composition.

Preparation of silica reinforced rubber composition and tire with component thereof

A self-balancing pneumatic tire is provided having a built-in balancing gel system. In one embodiment, the tire, before cure, includes a green pneumatic tire assembly having an uncured tread defining an outermost layer; a first barrier layer; a second barrier layer situated adjacent the first barrier layer and intermediate the first barrier layer and the tread; and first and second gel precursors. The gel precursors are non-flowable prior to cure but flowable after cure. The gel precursors are respectively contained within spaced-apart first and second circumferential regions defined by confronting, non-contacting surfaces of the first barrier layer and the second barrier layer, each circumferential region further situated proximate opposing sidewalls of the tire and having a width of about 5 percent to about 25 percent of a final tread width obtained upon curing of the uncured tire assembly. In one example, the first and/or second barrier layers can be discontinuous.

Self-balancing pneumatic tire and method of making the same

A pneumatic radial ply tire includes a pair of beads, a single carcass ply, a tread, and a pair of sidewalls. The pair of beads each has an associated chaffer. The single carcass ply is folded about each bead so as to define a main body portion and a turnup portion associated with each bead. The tread is disposed radially outward from the single carcass ply. The tread has shoulder portions disposed at axial outer edges of the tread. The pair of sidewalls extends radially outward from each chaffer to a location adjacent each shoulder portion. Each sidewall is disposed axially outward of the single carcass ply. Each sidewall includes a first outer layer extending from the chaffer to the shoulder portion and a second inner layer extending from the chaffer to the shoulder portion. The second inner layer is disposed entirely between the single carcass ply and first outer layer. The second inner layer comprises a foamed structure of a rubber composition having a density ranging from 0.1 to 1.0 g/cm.

Pneumatic tire with dual layer sidewall

The present invention relates to a tire containing a layered composite of sealant and air permeation resistant film, particularly a non-elastomeric film.
