A tire comprises a directional tread which forms a contact patch AC during running. The tread comprises a plurality of blocks (21A, 21B) which form a contact surface SC. The surface voids ratio is defined by TES=(AC−SC)/AC. The blocks (21A, 21B) are organized into patterns (26) of blocks of pitch P which succeed one another in the circumferential direction (X), in a pattern comprising at least one sipe. The sipes density is defined by the formulaSD=∑i=1nlpyiP*W*1000,where n is the number of sipes, lpyi is the projected distance of the sipe i in the axial direction (Y), and W is the width of the tread. Simultaneously, SD is at least equal to 10 mm-1 and at most equal to 70 mm-1, and TES is at least equal to 0.40 and at most equal to 0.70.
