ABSTRACT:
An elastic tire according to the invention comprises a tread (1) which comprises at least one unit (3) for measuring the grip of the tire on the ground, the measuring unit (3) being intended to come into contact with the ground on each revolution of the tire, and comprising, viewed at a radially outer face (5) of the tread (1), a central zone (10) and an encircling zone (20) surrounding the central zone (10), a sensor (40) sensitive to at least a tangential force exerted on the radially outer top (11) of the central zone (10) being provided opposite the top (11), the central zone (10) and the encircling zone (20) satisfying the two conditions:a) Rzzc<Rzze, andb) (i) Rxzc/Rzzc>Rxze/Rzzeor (ii) Ryzc/Rzzc>Ryze/Rzze, where: x, y and z represent the circumferential, axial and radial directions for the tire, Rzzcand Rzzerepresent the rigidities of the central zone (10) and of the encircling zone (20) under a force oriented perpendicularly to the radially outer face (5), Rxzcand Rxzerepresent the rigidities of the central zone (10) and of the encircling zone (20) under a force oriented tangentially to the radially outer face (5) in the circumferential direction (X) of the tire, and Ryzcand Ryzerepresent the rigidities of the central zone (10) and of the encircling zone (20) under a force oriented tangentially to the radially outer face (5) in the axial direction (Y).
