ABSTRACT:
A pneumatic tire (10) has a pair of sidewall portions (20), a pair of bead regions (22) and a carcass (30) reinforced with at least two sidewall fillers or inserts (42), (46) for each sidewall portion and at least one cord reinforced ply (38) and two bead cores (26) one in each bead region and a reinforcing belt structure (36). This tire is preferably a runflat radial ply tire. The at least one cord reinforced ply (38) has a pair of turnup ends (32) wrapped around the pair of bead cores (26). The turnup ends (32) each extend radially outwardly to a terminal end (33) at a radial height of at least 40% of the tire section height (SH). The first insert for each sidewall portion lies radially inward and adjacent the at least one ply (38). The second insert (46) for each sidewall portion is a bead filler insert radially above the bead core (26) and between the at least one ply (38) and its turnup end (32).
