The invention relates to a pneumatic tyre having a carcass and a belt reinforcing structure. The belt reinforcing structure comprises a first belt layer having cords arranged at an angle of 10 degrees or less with respect to the centerplane of the tyre, and a zigzag belt reinforcing structure located radially outward of the first belt layer. The zigzag belt reinforcing structure forms two layers of cords, the cords being inclined at 5 to 30 degrees relative to the centerplane of the tyre extending in alternation to turnaround points at each lateral edge. The first belt layer is wider than the zigzag belt reinforcing structure. The ratio of the width between the wheel flange WBF to the belt width BW, WBF/BW, is in the range of from 0.84 to 1.0. |
