A bias tire carcass reinforced with hybrid cords consisting one ply aramide yarns (1) and one ply nylon yarns (2), and nylon content within cord is between 45 to 65%; the nylon yarn content within those range improves fatigue resistance and reduces sidewall gauge with respect to reference bias tire having nylon carcass; in one embodiment of the present invention, a bias tire carcass for pneumatic tires which have reinforcing layers comprising hybrid cords consist of one ply is made of aramide yarns and one ply is made of nylon yarns with 45-65% nylon content by weight, are balanced twisted cords.
