Pneumatic tire with buffer rubber layer

摘要

A pneumatic tire using an inner liner layer comprising a film of a thermoplastic resin, or a blend of a thermoplastic resin and an elastomer, having an air permeation coefficient of not more than 25x10^-12 cc.cm/cm².sec.cmHg and a Young's modulus of 1 to 1000 MPa, wherein a buffer rubber layer containing short fibers is arranged between the inner liner layer and a carcass layer in bead directions from two ends of a widest width belt layer in ranges of at least 20 mm, whereby a problem of trouble during production is solved and the durability of the inner liner layer is improved, without causing a problem of an increase in tire weight.
