A tire tread comprises transverse incisions (9) and circumferential incisions (3a, 3b, 3c) opening onto the tread surface, each incision having a mean radial depth E. The circumferential incisions have at the tread shoulder a mean circumferential radius of curvature Rc, a linear void ratio Tc, and an axial width Lc, and are spaced by length P from radial axis ZZ′ passing through the tire centre. The transverse incisions have at the tire shoulder a mean transverse radius of curvature Rt, a linear void ratio Tt, and an axial width Lt. The linear void ratio Tc is greater than or equal to 0.8E/Rt and less than or equal to 1.2E/Rt, the linear void ratio Tt is greater than or equal to 0.8E/Rc and less than or equal to 1.2E/Rc, Tc>Tt, and Lc is greater than or equal to 0.2 mm and less than or equal to 1.5 mm.
