Abstract
Pneumatic tires are rendered less susceptible to blow or blister defects by providing, in at least one cord reinforcement ply of a tire, a plurality of gas absorbing cords with the reinforcement cords and gas absorbing cords lying in the same general plane and with the gas absorbing cords consisting of staple hollow filaments. The gas absorbing cords may be used as fill yarn in weaving fabric employing parallel reinforcement cords.
