ADDITIVE FOR SILICA REINFORCED RUBBER FORMULATIONS

Thu, 21 Jul 2016 08:00:00 EDT

This invention is based upon the discovery that the silica compounding additives of this invention can be included in silica reinforced rubber formulations to increase the low strain dynamic stiffness exhibited by the rubber composition without a substantial increase in the cured compound hysteresis. This increase in stiffness allows for use of process aids that would otherwise result in an unacceptable further reduction in low strain dynamic stiffness. The present invention specifically discloses a rubber formulation which is comprised of (1) a rubbery polymer, (2) a reinforcing silica, and (3) a silica compounding additive of the structural formula: wherein M represents a divalent metal, and wherein R1 and R2 can be the same or different and are selected from the group consisting of hydrogen atoms, alkyl groups, alkylene groups, hydroxyl substituted alkyl or alkylene groups, amine substituted alkyl or alkylene groups and thiol substituted alkyl or alkylene groups.



Repair Boundary Indicator for Tires

Thu, 21 Jul 2016 08:00:00 EDT

A repair boundary indicator for an inflatable tire is disclosed. The repair boundary indicator is located on the interior or the exterior of the tire to indicate the boundary of the area of the tire that can be safely repaired.



Bias-Or Radial-Carcass Tire

Thu, 21 Jul 2016 08:00:00 EDT

Exterior surface of tire sidewalls have protuberances alternating with voids. The protuberances are arranged between points A, B and C, D. Point A is at the intersection of the radially exterior surface of the tire tread and of the sidewall. Radial axis ZZ′ is distant from equatorial plane AA′ by length LA of between ½ (L−20 mm) and ½ (L−80 mm), L being the external section width. Point B is at a radius greater than or equal to [R1+0.1 (RA−R1)] and less than RA, R1 being the radius at the external section width and RA being the radius at the point A. Point C is at a radius less than or equal to [R1−0.1(R1−R2)], R2 being the radius of the top of the rim flange. Point D is at a radius in the range R2

The land portions include at least one partitioned land portion in which a plurality of narrow width-direction grooves extending in a tread width direction are provided. A prescribed internal pressure is at least 750 kPa. A depth of the circumferential-direction grooves, represented by H, satisfies a relationship 7 mm≦H≦13 mm. A tread circumferential-direction spacing of the narrow width-direction grooves, represented by W, satisfies a relationship 5 mm≦W≦20 mm.



Pneumatic Tire

Thu, 21 Jul 2016 08:00:00 EDT

A pneumatic tire is provided with a tread, a pair of sidewalls, and a pair of beads. A plurality of bending grooves are provided in an intermediate land located on the inner side of each shoulder main groove. Each of the bending grooves has one end portion opening to the shoulder main groove and the other end closed in the intermediate land. Each of the bending grooves is composed of a first tilting groove portion extending from the opening end portion to the bending portion and a second tilting groove portion extending from the bending portion to the closed end portion. The direction oriented from the opening end portion of the first tilting groove portion toward the bending portion coincides with the rotational direction, and the second tilting groove portion is bent toward the first tilting groove portion with the bending portion serving as an apex.



TIRE WITH NOISE-REDUCING TREAD PATTERN

Thu, 21 Jul 2016 08:00:00 EDT

A tire includes a tire carcass and a tread extending circumferentially about the tire carcass The tread includes a plurality of tread elements disposed in a tread pattern. The plurality of tread elements have one of two different pitch lengths and are disposed in a noise-reducing pitch sequence.



TIRE INCLUDING A REINFORCEMENT FOR REINFORCING A SIDEWALL

Thu, 21 Jul 2016 08:00:00 EDT

A tire (10) comprises: a crown (12) surmounted by a tread (20), two sidewalls (22), two beads (24), each sidewall (22) connecting each bead (24) to the crown (12), a carcass reinforcement (32) anchored in each of the beads (24) and extending from each bead (24) through each sidewall (22) and comprising textile filamentary carcass reinforcing elements, a sidewall reinforcing reinforcement (25) comprising textile filamentary sidewall reinforcer reinforcing elements.
