Abstract
High modulus reinforcement is used to make a radial ply pneumatic tire having only one carcass ply, i.e. a monoply tire. Poly-ethylene naphthalate (PEN) reinforcement is prepared in a manner that provides sufficient strength whereby the monoply tire can be made having reduced weight (as compared to a two ply tire) while having comparable durability, some improved handling, reduced rolling resistance, and improved flatspotting properties.
