Summary:PROBLEM TO BE SOLVED: To provide a tire for a wheel, a tread band, and a crosslinking elastomer composition. SOLUTION: This tire is the tire for the wheel equipped with at least a component part manufactured from a crosslinking elastomer, and the component part comprises an elastomer composition comprising (a) at least a kind of diene elastomer polymer, and (b) an elastomer composition containing ethylene, at least a kind of aliphatic α-olefin, and arbitrarily at least a kind of copolymer with a polyene, and the copolymer has a molecular weight distribution (MWD) index of less than 5, preferably 1.5-3.5, melt enthalpy (ΔaHm) of not smaller than 30 J/g, preferably 34 J/g-130 J/g. The component part containing the composition is preferably a tire tread band. COPYRIGHT: (C)2009,JPO&INPIT
