A pneumatic radial tire includes a pair of opposing bead areas, in which each bead area includes a bead core and a bead apex. At least one carcass reinforcing ply includes a turn up at each bead core, and each turn up includes a radially outward end. A pair of chippers is disposed at each turn up, in which the pair of chippers includes a first chipper and a second chipper. The first chipper is disposed axially inwardly of the second chipper and includes a radially outward end that is disposed radially outwardly of the radially outward end of the turn up. The second chipper includes a radially outward end that is disposed radially outwardly of the radially outward end of the first chipper, in which forces due to deflection of the tire are absorbed by the pair of chippers to reduce stresses along each turn up.
