Abstract: A mold (20) for vulcanizing tires comprises an upper part (24) and a lower part (26), the upper part and the lower part being able to move axially between an open position and a closed position in which the lower part and the upper part meet along a joint line (31). A mold part (24, 26) has at least one sipe blade (50), all or some of the sipe blades extending substantially axially or helically on the radially internal surface (30) of the mold, all or some of the sipe blades being: contiguous at one of their ends with a protruding element (46) and contiguous at the other of their ends with a recessed element (44) or with the other part of the mold, and able to move relative to the tire in the wake of the protruding element (46), during opening of the mold.

Abstract: A tire for an agricultural vehicle, having a tread made of rubbery material and two axially outer zones delimiting the tread, each having a shoulder and a sidewall and designed to mechanically connect the tread to a rim. The tire has a plurality of blocks distributed in a circumferential direction (X), each block having a length L, measured in the circumferential direction (X) from a lateral face of the block, and a height H, where L is greater than H. Each block has a cavity that opens onto the lateral face, forming an opening in the lateral face. The cavity has a depth p and an opening width l. The blocks are present in at least one of the two axially outer zones, but not in the tread. The blocks are present at the shoulder in the continuation of the tread.
