IMPROVEMENT TO PNEUMATIC TIRES FOR VEHICLE WHEELS Abstract of the Disclosure A pneumatic tire for motor vehicles having a generally trapezoidal section is provided. The tire has a top portion which is generally convex towards the outside and wider than any other part of the tire, beads, and two sidewalls which spread outwardly from the beads as far as the zones which connect the sidewalls and the top portion. The top portion has a central tread portion which is normally in contact with the ground and lateral shoulders which are spaced from the ground when the tire is under load. The sidewalls have in the zones which connect them to the shoulder, a section of less bending stiffness in comparison with the central part of the sidewall and of the shoulder. A generally annular reinforcing structure which is substantially inextensible in the axial and circumferential directions and is folded at its ends about reinforcing annular straps is arranged in the shoulder. In any radial section, the cincture connection angle is between - 10° and 40°, being defined as "negative" the angle lying in a radially inner position with respect to the line parallel to the tire axis which constitutes one side of said angle.
