The tread has main grooves that delimit a central region of a width comprised between 15 and 25% of a total width W and that define the wearable thickness of the tread. The tread also has lateral regions on each side of the central region, and the lateral regions are divided into raised elements. The elongate elements are delimited by oblique secondary grooves which are inclined by a mean angle of between 35 degrees and 55 degrees with respect to the circumferential direction and have a depth P5 which is between 30% and 60% of the depth P. Each elongate raised element has an oblique cut which divides the element into two elongate element halves, and each oblique cut is formed by a sipe extended by an internal canal. The internal canal forms a new groove once the tread is partially worn before the oblique secondary grooves completely disappear.
