摘要

The radial type vehicle pneumatic tire has an inner layer facing the tire inner side, a carcass layer with a reinforcement material extending in radial direction and an additional layer placed between carcass layer and inner layer. The additional layer is made of a calendered or extruded reinforcement material, such as polyester, particularly polyethylene terephthalate, regenerated cellulose or cellulose ester, such as rayon, polyamide, aromatic polyamide, glass fiber or natural fiber. The rubber composition of the squeegee layer is equal to the rubber composition of an inner tire component.
