Claim:
1. A pneumatic tire comprising a layer made of a thermoplastic resin composition comprising an ethylene-vinyl alcohol copolymer and 5 to 80% by weight of a polyamide resin based upon the total amount of the ethylene-vinyl alcohol copolymer and the polyamide resin, wherein only one maximal crystallization peak point is observed in the curve of heat flow versus temperature in a cooling process of a differential scanning calorimetry of a melt-kneaded product of 25 parts by weight of the ethylene-vinyl alcohol copolymer and 75 parts by weight of the polyamide resin; wherein for the differential scanning calorimetry, the temperature of the melt-kneaded product is elevated to 260° C., and the quantity of heat in a cooling process of 10° C./min is measured to observe the crystallization peak.
