| 20140202608 | RUBBER CEMENT AND TIRE WITH FABRICATED TIRE TREAD - The invention relates to a rubber cement, fabricated tire tread and resulting tire, where the tire tread is fabricated by joining ends of an uncured rubber strip together with a silica coupler-containing rubber cement between opposing ends of the uncured tread rubber strip where the rubber strip contains a high content of hydrophobated precipitated silica and where the cement contains a silica coupling agent. | 07-24-2014 |
| 20140202619 | ADHESIVE BONDING FOR A PNEUMATIC TIRE - A system for constructing a pneumatic tire includes a tread component having two opposite tread splice ends, a water based adhesive applied to the tread splice ends for securing the tread splice ends to each other; and a heating means applied to the tread splice ends and water based adhesive for reducing drying duration of the water based adhesive. | 07-24-2014 |
| 20140255654 | TIRE WITH RIBBED TREAD - The invention relates to pneumatic tires with ribbed treads which may be, for example pneumatic tires such as bus tires and truck tires. | 09-11-2014 |
| 20150007926 | TIRE CONTAINING SILICATE MICROFLAKES HAVING ENHANCED TRACTION CHARACTERISTICS - This invention discloses a tire having enhanced wet traction and ice traction characteristics. These tires are 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, wherein the tread includes at least one circumferential groove which separates circumferential ribs, each circumferential groove having two sides and a base therebetween, and wherein the sides of each circumferential groove are comprised of a rubbery composition that includes silicate microflakes which are substantially aligned in an orientation which is parallel with the sides of the grooves. | 01-08-2015 |
