<p>A pneumatic tire for heavy load vehicles having a carcass layer, an inner liner layer and an inner surface protecting layer which lies between the carcass and the inner layers and comprises rubber layers (A) and (B), is new. The rubber layer (A) is adjacent to the inner liner layer, and the rubber layer (B) is adjacent to the carcass layer. The inner liner layer, the carcass layer, rubber layer (A) and rubber layer (B) are independently composed of rubber compositions comprising a rubber component, sulfur and a cobalt salt of an organic acid in which the amount of the sulfur contained in the rubber compositions satisfy the following relationships (I) and (II). SA, SB, SC represent the amounts of sulfur compound in the compositions constituting layer (A), layer (B) and the carcass layer, respectively, based on 100 pts wt of the rubber composition.</p> |
