1. An agricultural tool used to form furrows, comprising:
- a generally cylindrical support and a plurality of tires, each tire comprising;
a sole by way of which the tire is mounted on the support, the sole comprising, at opposing ends of the sole in an axial direction of the generally cylindrical support, radially extending lateral surfaces,a tread opposite the sole, andtwo sidewalls that connect the tread to the sole via respective junction points, each junction point being situated at a radial position corresponding to an outermost radial end of a respective lateral surface, the sole, the tread and the sidewalls jointly forming a deformable casing,wherein 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, and 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,wherein a straight line passing through a crown of the tread and through one of said junction points crosses a respective lateral surface of the sole, andwherein each of the sidewalls has a curvature of constant sign from the tread to the junction point.

Abstract
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.
