FIELD: transportation.

SUBSTANCE: tire (1) has tread (2) containing central part (L1) located across the equatorial plane (XX), first shoulder part (L2) located towards the outside of the tire, and second shoulder part (L3) located towards the inner side of the tire. Central part (L1) is separated from the first shoulder part by two first circumferential grooves (3, 6). First shoulder portion (L2) and second shoulder portion (L3) comprise a plurality of first transverse grooves (56, 66) having a first end located substantially at respective tread edge (2), having a width greater than or equal to about 4 mm, and the length in the axial direction is equal to at least 50% of the width of the shoulder in which they are located. Number of first transverse grooves (56, 66) of first shoulder part (L2) is less than the number of the first transverse grooves of second shoulder part (L3). Central part (L1) contains at least one circumferential edge (9, 10, 11) containing a plurality of second transverse grooves (16, 17, 18). Second transverse grooves (16, 17, 18) have a maximum width that is less than or equal to about 3 mm, and a void ratio that is less than or equal to about 0.06 is determined at said at least one circumferential edge (9, 10, 11).

EFFECT: technical result is improved tire operating characteristics.
