Disclosed herein are tire tread rubber compositions comprising a specified elastomer component, reinforcing silica filler, a specified hydrocarbon resin, oil, and a cure package. The elastomer component includes styrene-butadiene rubber; polybutadiene; and guayule natural rubber.

Tire tread rubber composition

Disclosed herein are processes for preparing a resin-extended rubber by mixing at least one thermoplastic resin with a resin-rubber-solvent cement comprising at least one conjugated diene monomer-containing rubber and the resin-extended rubber resulting from such processes. Also disclosed is a resin-extended rubber-solvent-cement comprising at least one conjugated diene monomer-containing rubber, at least one non-polar solvent, and at least one thermoplastic resin as well as a rubber composition comprising a resin-extended rubber.

Resin-extended rubber and process for preparing

Disclosed herein are tire tread rubber compositions comprising a specified elastomer component, reinforcing silica filler, a specified hydrocarbon resin, a cure package, and optionally oil. The elastomer component includes at least one styrene-butadiene rubber having a silica-reactive functional group; and guayule natural rubber.

Disclosed herein are tire tread rubber compositions comprising a specified elastomer component, reinforcing silica filler, a specified hydrocarbon resin, oil, and a cure package. The elastomer component includes styrene-butadiene rubber; polybutadiene; and natural rubber, polyisoprene, or a combination thereof.

Disclosed herein are tire tread rubber compositions comprising a specified elastomer component, reinforcing silica filler, a specified hydrocarbon resin, a cure package, and optionally oil. The elastomer component includes styrene-butadiene rubber and polybutadiene.

Disclosed herein are tire tread rubber compositions comprising a specified elastomer component, reinforcing silica filler, a specified hydrocarbon resin, liquid plasticizer, and a cure package. The elastomer component includes styrene-butadiene rubber; polybutadiene; and natural rubber, polyisoprene, or a combination thereof. Also disclosed are methods for providing a tire tread having improved dry handling performance while maintaining wet traction performance and wear.

Tire tread rubber composition and related methods

Disclosed herein are tire tread rubber compositions comprising a specified elastomer component, reinforcing silica filler, a combination of specified hydrocarbon resins, liquid plasticizer, and a cure package. The elastomer component includes styrene-butadiene rubber; polybutadiene; and natural rubber, polyisoprene, or a combination thereof. Also disclosed are methods for providing a tire tread having improved dry handling and wet traction performance.

Disclosed herein are tire tread rubber compositions comprising a specified elastomer component, reinforcing silica filler, a specified hydrocarbon resin, liquid plasticizer, and a cure package. The elastomer component includes styrene-butadiene rubber and polybutadiene and also may include a limited amount of natural rubber, polyisoprene, or a combination thereof. Also disclosed are methods for providing a tire tread having balanced wet traction, winter and wear performance.

Disclosed herein are tire tread rubber compositions comprising a specified elastomer component, reinforcing silica filler, a specified hydrocarbon resin, a cure package, and optionally oil. The elastomer component includes at least one styrene-butadiene rubber having a silica-reactive functional group; and natural rubber, polyisoprene, or a combination thereof.

The present disclosure is directed to rubber compositions comprising at least one rubber, at least one reinforcing carbon black filler, and a whey protein component. The whey protein component is in an amount sufficient to provide about 0.1 to about 10 phr whey protein. The present disclosure is also directed to methods of preparing such rubber compositions and to tire components containing the rubber compositions disclosed herein.

Rubber compositions containing carbon black and whey protein

Disclosed herein are a sealant composition for use with tires, a tire having at least one component with at least one surface at least partially coated with the sealant composition, and related methods for applying the sealant composition to tires. The sealant composition comprises biorubber and a softener comprising at least one of plant oil or plant resin and has a non-petroleum content of at least 70% by weight.
