  • Reinforcement package for tires
    Patent number: 6668889
    Abstract: A pneumatic tire (10) having a reinforcement package including a mid-ply belt having reinforcement at a 0° angle with respect tothe equatorial plane (EP) of the tire shows improved handling and durability. The mid-ply belt comprises reinforcing cords or filaments (28) that are discontinuous. The dicontinuous cords or filaments (28) make possible the production of a uniform tire in most tire designs, and the reinforcement of the mid-ply belt provides a tire with improved durability and handling properties. A tire with superior properties was produced using reinforcing cords or filaments (27) and (28) which are made from polyethylene napthalate.
