1. A tire for an agricultural vehicle, comprising:
a tread made of rubbery material configured to come into contact with the ground while the tire is running; and
two axially outer zones delimiting said tread, said axially outer zones being designed to mechanically connect said tread to a rim, each axially outer zone comprising:
a sidewall;
a shoulder disposed between said sidewall and the tread; and
a plurality of individual blocks distributed in a circumferential direction (X),
each block having a length L and a height H where L is greater than H, said length L being measured in the circumferential direction (X) from a lateral face of said block,
each individual block of the plurality of blocks having a single cavity that opens onto said lateral face, forming an opening in said lateral face, said cavity having a depth p and an opening width l,
each individual block has another lateral face on the opposite side from the lateral face comprising said opening, the other lateral face having an angle with respect to the circumferential direction that is less than an angle with respect to the circumferential direction of the lateral face comprising said opening,
each individual block having an external face configured as a plateau arranged between the other lateral face and the lateral face,
the cavity facing a rolling direction of the tire,
the blocks of the plurality of blocks being present in at least one of the two axially outer zones, said blocks not being present in the tread, and
each of the blocks are present at the shoulder in the continuation of the tread,
wherein the other lateral face is arranged at a first angle with respect to the circumferential direction (X), the lateral face arranged at a second angle with respect to the circumferential direction (X), and the plateau is arranged at a third angle with respect to the circumferential direction (X), wherein the first angle, the second angle, and the third angle are different from each other.
