These "confluent ply" assemblies have each piece extend from one bead up to and across the crown area to terminate short of the opposite tire sidewall, the tire having the cords in these bias plies at the center crown area at one specific bias angle to a tire radius line where all of such cord angles of each individual "confluent ply" piece are inclined in one rotary direction of the tire. The pneumatic tire carcass of the invention may include a plurality of "confluent ply" cord assemblies wherein the cord angles of said ply assemblies are inclined in opposite rotary direction to an even number or to the majority of the confluent plies in the tire and carcasses also may include conventional belt plies and known reinforcing plies positioned therein in normal manners.
