ABSTRACT:
The invention relates to the use of longitudinally extending reinforcing cords associated with the pneumatic tire to control radial force variations in the tire under loaded conditions, and the method for applying such longitudinal reinforcing cords to the tire either in its new form, or as a retreaded tire from an old carcass. Basically, the longitudinal cords are made from a very high strength cord material having a tensile strength of approximately 125 pounds each, with the cords spaced at approximately 1/2-inch spacings. The cords could be increased to 150 or more pounds each. There will be between about 8 to about 20 cords, depending upon the width of the tread area of the tire involved. This type of construction serves as an extra belt of many hundred pounds tensile strength, thereby controlling radial force variations in the tires, and is particularly applicable to controlling these forces in radial tires.
