Abstract:
A tire having at least one component of a rubber composition which comprises, based upon 100 parts by weight elastomer(s), (A) 100 parts by weight of at least one diene-based elastomer, (B) about 30 to about 100 phr of reinforcing filler consisting essentially of (1) about 30 to about 100 phr of a modified silanol-containing carbon black which contains (a) a plurality of silanol groups bonded on its surface and (b) a plurality of hydrocarbon radicals grafted on its surface and (2) zero to about 70 phr of at least one reinforcing filler selected from carbon black, precipitated silica, aluminosilicate and silanol-containing carbon black without said hydrocarbon radicals and (C) a coupling agent having a moiety reactive with silanol groups on the surface of said modified carbon black, precipitated silica, aluminosilate and silanol-containing carbon black and another moiety interactive with said elastomer(s); wherein said hydrocarbon radicals are comprised of at least one of alkyl, aryl, alkaryl and aralkyl radicals, where said alkyl radicals are aliphatic hydrocarbon radicals having from 6 to 18 carbon atoms, where said aryl radicals contain from 6 to 24 carbon atoms, where said alkaryl radicals contain from 12 to 42 carbon atoms and where said aralkyl radicals contain from 12 to 42 carbon atoms.
