ABSTRACT:
A pneumatic tire having a carcass ply of metal cords arranged and embedded in the radial direction in a rubber is disclosed. This carcass ply has a natural sectional profile, and the position of the carcass ply in the shoulder portion of the tire satisfies the requirement of 0.3.ltoreq.t.sub.2 /t.sub.1 .ltoreq.1.0 in which t.sub.2 designates the thickness of the tire inside the carcass ply and t.sub.1 designates the thickness of the tire outside the carcass ply. In this shoulder portion, the thickness of an inner liner layer inside the carcass cord is gradually reduced toward the center of the tire top and the maximum width position of the tire. This pneumatic tire is preferably used for a high-load vehicle.
