A tyre for vehicle wheels includes a tread band having a first annular portion delimited by two circumferential channels. The first annular portion includes two annular grooves extending along respective zig-zag paths. Each of the two annular grooves is defined by a plurality of first parts…
A tyre includes a tread band, a tread surface which is radially external to the tread band, and a plurality of blocks formed on the tread band. Each block is at least partially delimited by a groove which defines a flank of the block. The flank is joined to a tread surface portion. The tread…
A vehicle tyre with an asymmetric internal structure and external profile relative to its middle line plane. When mounted on a rim and installed with a camber angle, the rotating tyre generates lateral forces during straight-line running: a camber force from the wheel's inclination, a structural…
A tyre includes at least one block on which at least one complex type sipe is obtained separating the block into two portions having a first surface and a second surface facing each other. The first surface is extended between a set of first and second longitudinal sections having, respectively, a…
A method for controlling the rolling resistance of a running tyre includes: manufacturing a tyre, installing the tyre on a rim, mounting a wheel on a vehicle. The tyre is manufactured by obtaining an external profile of the tyre that is asymmetric with respect to a middle line plane of the tyre and…
A winter tyre is described having a tread band wherein a plurality of blocks configured to obtain optimal performance both on snow-covered roads and on dry and wet roads in specific conditions of use (in particular during acceleration, braking or cornering with high power vehicles). Each of the…
A motorcycle tyre intended to be fitted to the rear wheel of a motorcycle. The motorcycle tyre has a tread pattern with a high void-to-rubber ratio that provides a suitable draining. The tread pattern has pairs of primary grooves to carry out the draining function of the tyre, and arranged…
