A tire having a contact face of a width TW is provided. The contact face is intended to come into contact with ground during rolling. The tread is provided with at least one groove of a depth D provided with a wear indicating means that extends generally in a circumferential orientation and opens to the contact face. The tread comprises a center region and a pair of shoulder regions that are positioned on two axial sides of the center region. The shoulder regions each comprise a shoulder rubber layer of a thickness ts made of a shoulder rubber composition different from a rubber composition constituting the tread. A shear storage modulus G′ of the shoulder rubber composition measured at 23° C., 10 Hz and 10% of strain is less than or equal to 1.0 MPa.

The present invention relates to the system for measuring the slip of a tyre (10) with respect to a rim (20), on which said tyre (10) is mounted.

In particular, said system comprises a first electronic device (1) and a second electronic device (2), each of which is configured at least to acquire, filter, store and send data, and a processing unit (3), external to said electronic devices (1, 2), configured at least to receive and process the data sent by each electronic device (1, 2), in order to measure said slip by measuring an angle (α) and comparing the value of this angle with respect to at a reference angle α.sub.ref.

The present invention also relates to method for measuring the slip of a tyre (10) with respect to a rim (20), on which said tyre (10) is mounted.
