Abstract
In a pneumatic tire composed of a carcass layer crossing between a pair of left and right bead cores, the bead cores comprise a fastening bead core for fastening an end of the carcass layer to be turned up around the fastening bead core, and a non-fastening bead core free from the end of the carcass layer. An inner circumferential radius R2 of the non-fastening bead core is set smaller than an inner circumferential radius R1 of the end of the carcass layer to be turned up around the fastening bead core.
