In a pneumatic tire, a cord spacing between an axially outer cord layer and an axially inner cord layer such as: a turnup portion and a main portion of a carcass ply; or a bead reinforcing cord layer and a carcass ply turnup portion, is increased from the radially inside to the outside of the tire to improve the durability of the bead portion.
