ABSTRACT:
The turn-up portion of the carcass ply (12) in the bead portion of a pneumatic tire is interposed between the bead core (11) and a clamping member (18). The bead core (11) has a radial cross section which is substantially pentagonal. The clamping member (18) comprises a heat shrinkable material that secures the turn-up portion of the carcass ply in a desired location. Elastomeric stiffening members (19,20) are disposed on each side of the carcass ply (12) in the bead portions and lower sidewalls of the tire. The assembly of a tire according to the invention mounted upon a specified rim (22) is also disclosed.
