Abstract

PURPOSE:To provide the titled tire outstanding in fracture and wear resistances, low in heat generation during running, with the tread and/or sidewall made up of a specific organometallic halide-modified butadiene rubber. CONSTITUTION:The objective tire with the tread and/or sidewall made up of a rubber composition comprising (A) 10-100wt.% of a butadiene rubber containing >=70% of cis 1,4-linkage with a weight-average molecular weight of 300,000-1,200,000 and molecular weight distribution index of 3-15, prepared by reaction of a compound an organometallic halide of formula II (R' is 1-20C alkyl or aryl; M is Sn or Ge; X is halogen) with a polymer derived from polymerization of 1,3-butadiene in an inert organic solvent in the presence of a catalyst containing a lanthanide series rare earth element compound and organoaluminum compound of formula I (R1-R3 are each H or 1-8C hydrocarbon group, but all of them not being H) and furthermore, if needed, Lewis acid and/or Lewis base and (B) 90-0wt.% of a diene rubber such as natural rubber or isoprene rubber.
