What is claimed is: 1. A pneumatic tire comprising at least one component, the at least component comprising a rubber composition, the rubber composition comprising 100 parts by weight of a diene based elastomer; from 1 to 20 parts by weight, per 100 parts by weight of elastomer (phr), of a solvent

What is claimed is: 1. A pneumatic tire comprising at least one component, the at least component comprising a rubber composition, the rubber composition comprising 100 parts by weight of a diene based elastomer; from 1 to 20 parts by weight, per 100 parts by weight of elastomer (phr), of a solvent-extracted asphaltene, wherein the solvent-extracted asphaltene comprises greater than 5 percent by weight of sulfur, based on the total weight of the asphaltene; and from 0.5 to 8 phr of a sulfur vulcanizing agent. 2. The pneumatic tire of claim 1, wherein the solvent-extracted asphaltene is present in the rubber composition in a concentration ranging from about 1 to about 15 parts by weight, per 100 part by weight of elastomer (phr). 3. The pneumatic tire of claim 1, wherein the solvent-extracted asphaltene comprises greater than 7 percent by weight of sulfur, based on the total weight of the asphaltene. 4. The pneumatic tire of claim 1, wherein the solvent-extracted asphaltene comprises greater than 8 percent by weight of sulfur, based on the total weight of the asphaltene. 5. The pneumatic tire of claim 1, wherein the diene based elastomer is selected from the group consisting of cis 1,4-polyisoprene rubber (natural or synthetic), 3,4 -polyisoprene rubber, styrene/isoprene/butadiene rubber, emulsion or solution polymerization derived styrene/butadiene rubbers, cis 1,4-polybutadiene rubbers and emulsion polymerization prepared butadiene/acrylonitrile copolymers. 6. The pneumatic tire of claim 1, wherein the rubber composition further comprises from about 10 to about 100 phr of carbon black. 7. The pneumatic tire of claim 1, wherein the rubber composition further comprises from about 5 to 70 phr of at least one oil selected from the group consisting of aromatic, paraffinic, naphthenic, vegetable oils, MES, TDAE, SRAE and heavy naphthenic oils. 8. The pneumatic tire of claim 1, wherein the sulfur vulcanizing agent is elemental sulfur.
