Abstract: This invention relates to certain rubber formulations which exhibit a low level of hysteresis which are comprised of a chemically functionalized renewed rubber and virgin solution styrene-butadiene rubber. These rubber formulations are loaded with a reinforcing silica. The rubber formulations of this invention can be utilized in making rubber products such as, tires, tracks, and conveyor belts which will promote energy savings by virtue of their low hysteretic properties. The present invention more specifically discloses a rubber composition which is comprised of (1) a solution styrene-butadiene rubber; (2) a functionalized renewed rubber composition which is comprised of an elastomeric polymer and a stabilizer; wherein the rubber composition has a crosslink density which is within the range of 0.05 to 2.0×10−5 mole/g, and wherein the rubber composition has a solubility fraction of less than 90 percent; and (3) a reinforcing filler including reinforcing silica.

Abstract: This invention discloses a tire having crack resistant sidewalls which include a micronized rubber powder. 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, and wherein the sidewalls are comprised of 20 phr to 80 phr of natural rubber, 20 phr to 80 phr of polybutadiene rubber, and 3% over batch weight to 20% over batch weight of micronized rubber powder, wherein the micronized rubber powder has a particle size which is within the range of 40 Mesh to 300 Mesh.
