ABSTRACT:
A runflat radial ply pneumatic tire 10 has a carcass 30 which has a pair of sidewalls 20, each sidewall being reinforced with at least two sidewall fillers or runflat inserts 42, 46 and at least two cord reinforced plies 38, 40 and a bead core 26. The tire has one or more reinforcing belts 36. Each sidewall has at least one ply 38 or 40 reinforced with cords, the cords have a modulus E of X, X being at least 10 GPa. At least one ply has a turnup end 32 wrapped around the bead core 26. A first ply 38 or 40 is reinforced with substantially inextensible cords having a modulus E greater than X of the cords of the other ply. The second ply 38 or 40 is spaced from the first ply 38 or 40 by the second filler or runflat insert in the sidewall 20.
