Tread for civil engineering tires, having blocks in the central part and edge ribs, each block having a width Ltb measured parallel to transverse edges and a width Lcb measured along the circumferential direction, wherein each edge rib has a plurality of recesses, forming housings, with a transverse width Lte and a circumferential length Lce, delimited over the whole of its height He by transversely orientated walls and a circumferentially orientated wall, having a suitable geometry to receive at least an end part of a block of the central region with a circumferential clearance Ac in the circumferential direction and a transverse clearance At in the transverse or axial direction, these clearances determined to ensure that, in the usual running conditions of the tire the end part of said block of the central region is at least partially in contact with at least one of the transversely orientated walls of each recess, thereby preventing each of the blocks, having its ends locked in said recesses, from coming into contact with the neighboring blocks of the central row.
