Tread for a heavy vehicle tyre, this tread having, in the new state, a tread surface of width W that is intended to come into contact with a roadway, this tread having a thickness PMU of material to be worn away during running and comprising: - a mid-plane XX' that divides the tread into two tread halves, - four grooves (21, 22) of circumferential overall orientation that are formed symmetrically with respect to the mid-plane, - the two grooves closest to the mid-plane delimiting a central region having a width at least equal to 13% and at most equal to 20% of the total width W of the tread, - on each side of the tread with respect to the mid-plane, an intermediate region that is delimited by two grooves of circumferential overall orientation, each intermediate region having a width of between 13% and 30% of the width W of the tread, - an edge region axially on the outside of each intermediate region, - each of the intermediate regions being divided into a plurality of elongate raised elements, the contact faces of which that are intended to come into contact with the roadway during running comprise long sides and short sides, these elongate raised elements delimiting oblique grooves, these oblique grooves having an average width at least equal to 5 mm and opening into the circumferential grooves (21, 22) that delimit the intermediate regions and being inclined at an average angle of between 30 degrees and 60 degrees, this angle being measured with respect to the circumferential direction, these elongate raised elements having an average length in the circumferential direction equal to the length of the short sides and between 50 and 70 mm, the depth of the oblique grooves being at least equal to 30% of the depth of the circumferential grooves (21, 22), - each elongate raised element of the intermediate regions also comprising an internal and oblique cut that extends in a direction equal or similar to the direction of the oblique grooves bordering this elongate raised element and divides the element into two element parts so as to open onto the short sides of the element and is formed by a wide part forming a groove with a width at least equal to 25% and at most equal to 110% of the width of the oblique grooves and by a narrow part forming a sipe with a width less than 1.0 mm, these wide and narrow parts being in line with one another, - each narrow part forming a sipe being extended radially inwards by a part forming a channel that is intended to form a new groove after a predetermined amount of wear - each internal and oblique cut having a total depth at least equal to 75% of the thickness PMU to be worn away, - each elongate raised element also comprising a plurality of sipes with a depth at least equal to 50% and at most equal to 100% of the depth of the oblique grooves, these sipes opening into the oblique grooves bordering the elongate elements, these sipes being oriented so as to intersect the internal and oblique cut. -
