A pneumatic tyre (14) of the semi-hollow type comprises a casing having an uninflated inner volume and comprising an inner wall (42) provided with a retaining bead (52) and a convex outer wall (44) forming the tread of the tyre, the inner wall (42) and the outer wall (44) of the tyre being connected by two annular borders (46, 48). The inner wall (42) of the tyre (14) is concave so as to surmount a convex outer wall (34a, 34b) of the peripheral seat (22) of a rim (12) of a wheel, this outer wall being provided with a peripheral slot (36) adapted to accommodate the retaining bead (52) of the tyre. Application particularly to depth control wheels and/or ground pressing wheels for agricultural machines.
