Abstract
Abstract A radial ply tire which minimizes lateral forces produced in the tire, which are usually transmitted over the carcass to the axis of the vehicle, while maintaining radial flexibility of the tire. The tire includes a pair of reinforcing strips between the carcass and the tread spaced on both sides of the equator of the tire and extending toward the shoulders. These reinforcing strips are covered by a reinforcing strip having radial cords.
