  • Passenger tire with chapex construction
    Publication number: 20020162616
    Abstract: A monoply pneumatic tire has a reinforced sidewall wherein the reinforcement comprises an extra long turn-up which extends into the belt area of the tire. The tire also has a robust chapex in the bead area of the sidewall which has a shape that results from wrapping the turn-up of the carcass ply around the bead of the tire without an apex. The chapex conforms to the shape of the bead. The material in the chapex corresponds in volume substantially to the combined volume of the apex and the chafer of a similarly sized tire.
