A tire tread for a heavy-duty vehicle of construction plant type and aims to reduce the risk of cracking at the sipe bottom, without significantly reducing the volume of material of the tread so as not to shorten the lifetime of the tire in respect of wear. The tread (I) has transverse sipes (5) having a depth H and a width E, each transverse sipe (5) having a radially inner end formed by a bulge (53) having an end radius R, the transverse sipes (5) being distributed longitudinally at a longitudinal spacing B, the depth H, the width E of each transverse sipe (5), the end radius R of the bulge (53) and the longitudinal spacing B satisfying the relationship (R*B)/(E*H)>=1.8.
