摘要： A tire having (i) an asymmetric tread profile with a shoulder drop difference of from 0.3 to 0.9; and (ii) an asymmetric tread pattern so as to have a ratio between the inner void/solid ratio and the outer void/solid ratio of from 1.1 to 1.50. By the above combination of features, handling and aquaplaning performance is remarkably improved even at high operating speeds without negatively affecting the wear resistance of the tread band.

摘要： In a process for producing self-sealing tyres for vehicle wheels, a green tyre (1) is built through assembly of at least one carcass ply (3), a belt structure (6), a tread band (7) and at least one layer of sealing material (10). The green tyre (1) is submitted to a curing and molding step. When the blow point (BP) and structural stability have been reached in the carcass ply (3), the belt structure (6) and the tread band (7), the process comprises the step of applying a working pressure (P 2 ) which is greater than the external-environment pressure (P e ) on a radially internal surface (16) of the tyre (1), which pressure is of such a nature as to counteract expansion of the gases developed during curing, internally of the sealing layer (10), until obtaining the substantial evacuation of these gases through a radially external surface (17) of the tyre (1).
