摘要：
A polymer composition for a tire having an air permeation coefficient of 25.times.10.sup.-12 cc.multidot.cm/cm.sup.2 .multidot.sec.multidot.cmHg (at 30.degree. C.) or less and a Young's modulus of 1 to 500 MPa, including (A) at least 10% by weight, based on the weight of the total polymer component, of at least one thermoplastic resin having an air permeation coefficient of not more than 25.times.10.sup.-12 cc.multidot.cm/cm.sup.2 .multidot.sec.multidot.cmHg (at 30.degree. C.) and a Young's modulus of more than 500 MPa and (B) at least 10% by weight, based on the total weight of the polymer component, of at least one elastomer component having an air permeation coefficient of more than 25.times.10.sup.-12 cc.multidot.cm/cm.sup.2 .multidot.sec.multidot.cmHg (at 30.degree. C.) and a Young's modulus of not more than 500 MPa, wherein the total amount (A)+(B) of the component (A) and the component (B) is not less than 30% by weight based on the weight of the total polymer component, and a pneumatic tire obtained therefrom.
