HEAVY-DUTY TIRE

A heavy-duty tire comprises a tread reinforcing belt comprising first to fourth belt plies each composed of belt cords inclined with respect to the tire equatorial plane. The first radial distance L between the belt cords of the third belt ply and the belt cords of the fourth belt ply is not more than the second radial distance L between the belt cords of the second belt ply and the belt cords of the third belt ply. The cord count E of the fourth belt ply is smaller than the cord count E of the third belt ply.
