The tread has a total width W and is provided with circumferential cuts that have a mean depth at least equal to 70 mm and at most equal to the thickness of wearable material. The circumferential cuts divide the tread into a middle region with an axial width Wm of 50% to 80% of the total width W. The middle region has transverse or oblique sipes opening into the circumferential cuts and closing at least in part when they enter the contact patch. The sipes have a depth at least equal to 75% of the depth of the circumferential cuts and delimit elements of material of height equal to the mean depth H of the said sipes and of circumferential length B equal to the mean distance between two sipes. For all the elements of material, the ratio H/B is greater than 0.5 and at most equal to 2.5.
