Appl. No.:

10/982294

Inventors:

David John Zanzig - Bertrange, LU
Jennifer Lyn Ryba - Wadsworth OH, US

Assignee:

The Goodyear Tire & Rubber Company - Akron OH

International Classification:

B60C 19/08
B60C 1/00
B60C 13/00

US Classification:

1521521, 152DIG 2

Abstract:

A pneumatic rubber tire with a sidewall having an outer visible layer of a rubber composition of a relatively high electrical conductivity, wherein the tire sidewall contains an internal rubber strip of relatively high electrical conductivity. Said internal rubber strip extends radially outward from a rubber chafer component of the tire to a tread base layer component of a rubber tire tread of a cap/base configuration, wherein said chafer and tread base rubber compositions are of a relatively high electrical conductivity. The rubber strip thereby provides a path of increased electrical conductivity relative to said outer visible layer of the tire sidewall extending from the tire chafer to the tread base layer tire components.

International Classification:

B60C 13/00

US Classification:

152525, 152458

Abstract:

This invention relates to a pneumatic rubber tire having a puncture resistant rubber sidewall. The said tire sidewall is comprised of an outer, visible annular configured sidewall rubber layer and an inner (non-visible) annular configured sidewall rubber layer integral with and underlying said outer sidewall rubber layer, wherein said inner sidewall rubber layer contains a dispersion of short fibers, wherein said short fibers are substantially aligned in parallel relationship to each other and substantially parallel to the said annular configuration of said inner sidewall rubber layer. In a further aspect of the invention, said tire is comprised of a carcass which contains a rubber carcass ply comprised of a rubber encapsulated cord reinforcement of a plurality of cords wherein said cords are positioned in a radially disposed spaced apart substantially parallel relationship to each other, wherein said rubber carcass ply is integral with and underlies said inner rubber sidewall layer and wherein said short fibers of said inner rubber sidewall layer are substantially aligned in a perpendicular direction to said cords of said underlying carcass ply.

Abstract:

This invention relates to a pneumatic tire with an outer, running surface containing, circumferential tread comprised of a styrene/butadiene (SBR) rich rubber composition containing two SBR's with spaced apart glass transition temperatures (Tg's), one of which is a functionalized SBR with a functional group reactive with hydroxyl groups on a precipitated silica, together with a combination of at least three resins with spaced apart softening points. The filler reinforcement is a combination of precipitated silica and specialized rubber reinforcing carbon black.

US Classification:

524492000, 152209500, 524495000

Abstract:

This invention relates to tires wherein at least a portion of its tire tread containing a running surface is of a rubber composition comprised of a functionalized elastomer, silica reinforcement, particularly precipitated silica aggregates which contain hydroxyl groups (e.g. silanol groups) and a blocked alkoxyorganomercaptosilane coupling agent. The rubber composition may constitute the entire, or major portion of, the running surface of the tread or may be limited to only a longitudinal circumferential strip, or portion, of the running surface of the tread. Such functionalized elastomer is an elastomer which contains functional groups distributed along the polymer chain and/or at its terminal end. Such functional groups may be divided into two categories, namely, a first category which promotes adsorptive interactions with the precipitated silica and a second category which chemically bonds to the precipitated silica. Such functionalized elastomer may contain functional group(s) from either of both of said first and second categories. In addition, said functionalized elastomer may be tin coupled.

US Classification:

1522095, 152541, 152525

Abstract:

This invention relates to a pneumatic rubber tire having a tread of a cap/base layered construction wherein said tire contains a first component as a tread cap layer having a running surface and at least two additional tire rubber components, wherein said tire components are comprised of rubber compositions which contain a maximum of 50 phr of reinforcing filler comprised of a maximum of 30 phr of rubber reinforcing carbon black. In one aspect, a purpose of such maximum of 30 phr of rubber reinforcing carbon black for said plurality of tire components is to promote a relatively low hysteresis property within said tire via such components to thereby promote relatively low rolling resistance for a pneumatic tire which contains such components. In practice, such additional tire components may be, for example, outer sidewall rubber layer, apex, chafer, belt ply and carcass ply components.
