A pneumatic tire comprises a tread; a bead region, a sidewall; a bead core; a first apex; an apex-extension; a carcass; a chafer and a second apex. The second apex is positioned between a rim flange protector and the first apex or the extension. The carcass includes a first ply turned-up around the bead core to form a first turnup portion extending along the first apex and the extension and terminating radially inwardly from the radially outward end of the extension. The carcass may include a second ply turned-up, between the bead core and the first ply, around the bead core to form a second turnup portion, the second turnup portion extending along the axially outer side of the first apex. Alternatively, the carcass may include a second ply parting from the first ply at the extension and extending along the extension and the turnup portion of the first ply.
