Abstract: Motorcycles tyre including a carcass structure, a zero-degree belt structure arranged in a radially outer position with respect to the carcass structure and a tread band arranged in a radially outer position with respect to the belt structure. The belt structure includes at least one hybrid reinforcing cord that has an elongation greater than 4% when subjected to a load equal to about 50 N and a tangent modulus with a monotonic progression as the elongation increases for elongations comprised between 4% and at least 9%.

Abstract: Tires for vehicle wheels having reduced environmental impact and the components thereof, in particular reinforcing structural elements such as carcass structures, belt structures, flippers and chafers, include elongated reinforcing elements treated with resorcinol and formaldehyde-free cross-linkable adhesive compositions. The adhesive compositions include at least a) a rubber latex, at least b) an epoxide and at least c) a polyamine with molecular weight higher than 190 Daltons, including at least two amino groups selected from primary —NH2 and secondary —NH— amino groups. In the structural element, these compositions confer an adhesion between cords and compounds that is comparable to, if not better than, the traditional RFL system in use in this sector.

Abstract: A method for controlling a motor vehicle including equipping the motor vehicle with front and rear tires having a transverse curvature ratio of at least 0.2 and a total height to chord ratio of at least 0.5, where at least one of the tires has an inflation pressure of between 50% and 90% of a low load reference value for normal driving and has a tread and a radial carcass with textile cords, which give the whole of the carcass a controlled elastic response allowing the motor vehicle to be controlled when there are sudden changes in speed and/or direction.
