Abstract
A heavy duty pneumatic tire, which allows the inside narrow-width belt layers to have a wide width as desired, and which suppresses the amount of strain generated at side edge portions of the belt layer to be sufficiently small thereby effectively preventing the separation of the belt layer, therefore the belt, in which two inside narrow-width belt layersB,B and two outside wide-width belt layersB,B, which have a larger width than the narrow-width belt layers, are sequentially disposed in the outer periphery side of the crown area of the radial carcass, wherein a portion of the wide-width belt layerB adjacent to the outer periphery side of the two narrow-width belt layersB,B, corresponding to side-edge vicinity of the narrow-width belt layerB of the outer periphery side is formed to be convex in radially outward direction.
