Tire having a composite belt structure

Abstract

A pneumatic tire having a carcass and a belt reinforcing structure wherein the belt reinforcing structure is a composite belt structure having at least one pair of radially outer zigzag layers and at least one spirally wound belt layer with cords inclined at an inclination of 5 degrees or less relative to the tire's centerplane and located radially inward of and adjacent to the at least two radially outer belt layers. The at least two radially outer zigzag belt layers have cords inclined at 5 degrees to 30 degrees relative to the tire's centerplane and extending in alternation to turnaround points at each lateral edge of the belt layer. At each turnaround point the cords are folded or preferably bent to change direction across the crown of the carcass thus forming a zigzag cord path.
