ABSTRACT:
A pair of high-transverse-curvature tires for two-wheeled vehicles is provided, in which the belt structure of the rear tire comprises a layer of inextensible cords disposed at a substantially zero angle with respect to the equatorial plane of the tire, preferably wound on a sheet of elastomeric material reinforced with aramid pulp, whereas the belt structure of the front tire comprises at least one radially outer layer of inextensible cords disposed at a substantially zero angle with respect to the equatorial plane of the tire and distributed with an axially variable density, and preferably another reinforcing layer at a radially underlying position. The zero-degree cords preferably are metallic cords of the high-elongation type, made of high-carbon steel. In the belt structure of the front tire the distribution density of the cords preferably continuously increases from the center to the belt ends, starting at the ends from a value of about 6 cords/cm at an area of a width included between 10% and 30% of the axial extension of the belt disposed on either side of the equatorial plane.
