Abstract
Official abstract text for this publication.
Provided is a pneumatic tire/rim assembly which is improved in the run-flat durability with the mass of the tire being reduced. In a pneumatic tire/rim assembly with a run-flat capability, an air bladder ( 2 ) made of a circular ring-shaped film body is inserted inside a pneumatic tire ( 1 ) mounted on a rim (R). At least part of the film body is formed of a sealing layer ( 3 ) made of a thermoplastic resin or a thermoplastic elastomer composition obtained by blending an elastomer in a thermoplastic resin.
First claim
