A press wheel comprises a rigid body and a semi-tubular tire. The tire comprises a flexible envelope with a sole portion through which the tire is mounted on the rigid body, a tread portion and a pair of sidewalls each one connecting the sole to the tread. The sidewalls extend, at least partially, along a generally concave profile, viewed from the exterior of the tire.

An assembly (1) comprises: a first structure (10) formed by first filamentary elements (15), a second structure (12) formed by second filamentary elements (16), a supporting structure (14) comprising supporting filamentary elements linking the first filamentary elements (15) and the second filamentary elements (16), and at least one filamentary securing element (18) interlaced with the first filamentary elements (15) and the second filamentary elements (16), one of the ends (18a, 18b) of the securing element (18) being free to slip relative to the first and second filamentary elements (15, 16).

An agricultural tool used to form furrows includes a generally cylindrical support and a plurality of tires. Each tire includes a sole by way of which the tire is mounted on the support, a tread opposite the sole (3) and two sidewalls that connect the tread to the sole. The sole, the tread (5) and the sidewalls jointly form a deformable casing. The tread of at least one of the plurality of tires has a generally domed shape. The sidewalls of this tire are generally inclined radially. The domed shape of the tread and the inclination of the sidewalls are such that the deformation of the casing urges the sole axially outward.
