In particular, such tire tread is comprised of at least three radially disposed zones of rubber layers composed of a radially outer tread rubber cap layer, a radially inner tread base rubber layer and an intermediate, transition rubber layer positioned between said outer rubber cap layer and said inner rubber base layer. The intermediate tread rubber contains a dispersion of glass and/or ceramic microspheres together with a coupling agent. | 10-15-2009 |
20100051164 | MODULAR PLY TIRE WITH DISSIMILAR MATERIALS - A tire carcass is disclosed herein which includes a first radial ply, first and second sidewalls, a carcass crown portion, the carcass crown portion having a first edge and a second edge, and a non-continuous second radial ply, the second radial ply having a right side extending from approximately the first edge of the carcass crown portion, and extending approximately to at least the first bead core and a left side extending from approximately the second edge of the carcass crown portion, and extending approximately to at least the second bead core, wherein at least one of the sidewalls and the carcass crown portion are made of dissimilar material. | 03-04-2010 |
20100065173 | TIRE HAVING TREAD WITH AN INTERNAL CLOSED CELLULAR RUBBER TRANSITION LAYER - The invention relates to a tire having a rubber tread configuration comprised of a circumferential non-cellular outer rubber cap rubber layer which contains a tread running surface, a circumferential internal, intermediate closed cellular rubber transition rubber layer positioned between said outer tread cap non-cellular rubber layer and a circumferential tread base non-cellular rubber layer. Said internal cellular rubber layer is thereby exclusive of said tread running surface and thereby abridges and joins said outer non-cellular rubber cap layer and said non-cellular base rubber layer of said tread configuration. | 03-18-2010 |
20100078110 | PNEUMATIC TIRE - 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
| 04-01-2010 |
20100132861 | TIRE WITH CELLULAR RUBBER TREAD RUNNING SURFACE - The invention relates to a tire having a tread with a cellular rubber running surface to promote a fast wearing tread running surface designed to expel internally heated tread rubber. | 06-03-2010 |
20100190885 | TIRE WITH RUBBER COMPONENT CONTAINING SILICA AND USE OF COMBINATION OF BLOCKED AND UNBLOCKED ALKOXYORGANOMERCAPTOSILANE COUPLING AGENTS - The invention relates to a tire having at least one component of a rubber composition comprised of at least one conjugated diene-based elastomer which contains silica reinforcement together with use of a combination of coupling agents for the silica. The coupling agent combination is comprised of blocked alkoxyorganomercaptosilane and unblocked alkoxyorganomercaptosilane coupling agents. Such tire component may be, for example, a tire tread. | 07-29-2010 |
20100200139 | PNEUMATIC TIRE HAVING AIR RETENTION INNERLINER CONTAINING ANCHORED GLASS MICROSPHERES - A pneumatic rubber tire having an integral rubber innerliner containing anchored hollow glass microspheres. | 08-12-2010 |
20110024011 | MODIFIED GEL PARTICLES AND RUBBER COMPOSITION - This invention discloses a tire which is comprised of a generally toroidal-shaped carcass with an outer circumferential tread, two spaced beads, at least one ply extending from bead to bead and sidewalls extending radially from and connecting said tread to said beads, wherein said tread is adapted to be ground-contacting, and wherein said tread is comprised of (1) a filler, (2) a cured rubbery polymer, and (3) core-shell particles which are comprised of (a) a crosslinked elastomeric core consisting essentially of repeat units that are derived from at least one conjugated diolefin monomer and from 15 weight percent to 30 weight percent at least one crosslinking monomer, wherein the crosslinked elastomeric core is a polymeric composition having a glass transition temperature which is within the range of −20° C. to 20° C., and (b) a polymeric shell which is derived from at least one vinyl aromatic monomer, wherein the polymeric shell has a glass transition temperature which is within the range of 50° C. to 160° C., and wherein the weight ratio of the core to the shell is within the range of 20:1 to 7:1. | 02-03-2011 |
20110048605 | RUBBER COMPOSITION CONTAINING SILICA REINFORCEMENT AND FUNCTIONALIZED POLYBUTADIENE RUBBER AND TIRES HAVING A COMPONENT THEREOF - This invention relates to a silica reinforcement-containing rubber composition which contains a functionalized polybutadiene rubber to promote a relatively low hysteretic loss to thereby enhance its desirability for tire sidewall and subtread applications in a sense of advantageously promoting reduced tire rolling resistance without significantly compromising various other desirable tire performance parameters. | 03-03-2011 |
20110226396 | TIRE HAVING TREAD WITH AN INTERNAL SOFTER TRANSITION RUBBER LAYER CONTAINING SHORT FIBER REINFORCEMENT - The invention relates to a tire having a rubber tread comprised of a circumferential outer cap rubber layer which contains a tread running surface and an underlying undertread layer of softer rubber than said outer tread cap rubber layer wherein said undertread layer rubber composition contains short fiber reinforcement. | 09-22-2011 |
