Provided is a thermoplastic resin composition from which an inner liner for pneumatic tires that decreases little in gas-barrier property upon fatigue can be produced. The thermoplastic resin composition comprises a matrix phase, which comprises an ethylene/vinyl alcohol copolymer (A), and a dispersed phase, which comprises a brominated isobutylene/p-methylstyrene copolymer (B) and an acid-modified styrene/ethylene/butylene/styrene copolymer (C), and is characterized by satisfying 0.02≤(WB×BB)×(WC×SC)/(WA×VA)≤0.85 where WA, WB, and WCare the weight proportions of the components (A), (B), and (C), respectively, to the total weight of the polymer components contained in the thermoplastic resin composition, VA(wt%) is the vinyl alcohol content in the component (A), BB(wt%) is the p-bromomethylstyrene content in the component (B), and SC(wt%) is the styrene content in the component (C).
