Abstract

A pneumatic tire with carbon fiber cord reinforcement wherein the carbon fiber cords have a round cross sectional shape and a twist per inch (TPI) of 1.2 to 1.6 turns per inch (TPI) is provided. Preferably, the carbon fiber cords are coated with an RFL or epoxy/RFL adhesive. It is also preferred that carbon fiber cords having an S twist and carbon fiber cords having a Z twist be used in the same reinforcing plies in the tire. Especially preferred is the incorporation of carbon fiber cords in a folded belt.
