Claim:
1. A rubber composition having an intramolecular double bond capable of sulfur cross-linking, comprising at least one of 1 to 100 parts by mass of carbon black and 10 to 150 parts by mass of an inorganic filler other than carbon black, 0.1 to 50 parts by mass of a sulfur-containing compounding agent and 0.1 to 30 part by mass of two or three terminal groups thioesterified hydrocarbon or oxyhydrocarbon compound, per 100 parts by mass of the rubber having an intramolecular double bond capable of sulfur cross-linking, wherein the both terminal groups thioesterified hydrocarbon or oxyhydrocarbon compound is a hydrocarbon derivative represented by the general formula [I] or [II], wherein A represents a divalent or trivalent group as an alkylene or oxyalkylene group of C 1 to C 20 ,an aryl group or an alkylene group substituted with an aryl group, and R 1 , R 2 R 3 , R 4 and R 5 are the same or different from each other, akylene or oxyalkylene groups of C 1 to C 20 , aryl groups, aralkyl groups, hydroxy groups, amino groups halogen groups, or hydrogen groups.
