Abstract:
A pneumatic tire comprises a carcass, a bead apex rubber, and a bead reinforcing cord layer. The bead apex rubber has a radially outer edge positioned at a radial height of 15% to 25% of the tire section height. The bead reinforcing cord layer comprises an axially inner first part disposed on the axially outside of a carcass ply main portion, and an axially outer second part disposed on the axially inside of a carcass ply turned-up portion. The radially outer edge of the axially outer second part is radially outwardly spaced apart from the radially outer edge of the carcass ply turned-up portion by at least 5 mm.
