20090151845 | PNEUMATIC TIRE - A pneumatic radial tire has a chipper in place of a traditional apex, the chipper located between a carcass main portion and turnup portion. The chipper layer may be composed of a chopped carbon fiber and aramid composite reinforced elastomeric layer. The tire sidewalls have a radial height SH and a section width SW located within a range of 0.4 to 0.44 of the sidewall radial height SH measured from the bead core. The section width SW may further be located within a range of 0.1″ to 0.3″ inches from a radially outward end of the chipper layer in a radial direction. The tread may of a dual layer construction, having a radially inward first layer formed of a relatively low rolling resistance compound and a radially outward second layer formed of a compound containing silica. | 06-18-2009 |
20090151856 | TIRE HAVING SIDEWALL WITH INTEGRAL COLORED MARKING COMPOSITE - This invention relates to a tire with a rubber sidewall having at least one layered rubber composite integral with a portion of its outer surface as a means of visibly identifying the tire. The layered composite is an integral composite in a sense of being comprised of a base rubber layer and a contrastingly colored marking rubber layer being partially pre-cured together prior to application to the outer surface of an uncured rubber sidewall. The integrally layered composite and tire rubber sidewall are integral in a sense of being co-cured together with the surface of the base rubber layer facing the rubber sidewall surface. The base rubber layer is a black colored carbon black reinforced rubber layer. The marking rubber layer is of color which contrasts with the black color of the base rubber layer. The base layer is a protective rubber layer which extends beyond the peripheral edges of said marking layer and is protective in a sense of inhibiting, or retarding, discoloring materials from migrating through it to the contrastingly colored marking layer. | 06-18-2009 |
20100132860 | TIRE CONTAINING CLOSED CELLULAR RUBBER FOAM IN ITS TIRE CAVITY WHICH CONTAINS DIVERSE CARBON BLACKS - Field of Invention The present invention relates to a pneumatic tire having its internal cavity containing a closed cellular rubber which contains a dispersion of at least two diverse carbon blacks to promote an improved path for thermal conductivity with suitable physical properties for the closed cellular foam rubber. | 06-03-2010 |
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 |
20110030865 | FOAM FILLED TIRE - The present invention relates to a pneumatic tire having its internal cavity filled with a closed cellular rubber contained within the tire cavity by a non-foamed rubber layer. | 02-10-2011 |
20110114240 | PNEUMATIC TIRE - A pneumatic radial tire having a circumferentially extending equatorial plane of the tire, the tire comprising a carcass, a tread radially outward of the carcass, the carcass comprising at least one carcass reinforcing ply, opposing bead portions, and opposing sidewalls, the carcass reinforcing ply having a main portion extending between the opposing bead portions and a pair of turnup portions, each turnup portion extending from one end of the main portion, each bead portion having a bead core, and a reinforcement cavity outward of each bead core, the cavity located between the main portion and one turnup portion of the at least one reinforcing ply, the tire characterized by:

20120012236 | TIRE WITH TREAD AND PREPARATION THEREOF - This invention relates to a pneumatic rubber tire having a rubber tread of a cap/base construction. More specifically, the invention relates to a tire having a tread with minimized, or inhibited, base peaking. | 01-19-2012 |
20120029114 | TIRE WITH RUBBER COMPONENT - Pneumatic rubber tire with a component comprised of a silica reinforced rubber composition comprised of specialized polybutadiene rubber, functionalized styrene/butadiene elastomer and cis 1,4-polyisoprene rubber. | 02-02-2012 |
