Abstract
The semi-hollow pneumatic tire has an axis of revolution and comprises a sole mountable on the periphery of a rotary support, a tread opposite the sole, and two sidewalls each connecting the sole and the tread so as to form together a cover which defines an uninflated chamber inside the pneumatic tire. The tread has a concave profile according to a plane passing through the axis of revolution, and the pneumatic tire comprises two annular ridges which extend, respectively, the two sidewalls in the outer radial direction and which are connected to two opposite ends of the tread, the two annular ridges defining, respectively, two principal directions which intersect at an acute angle so that, when the pneumatic tire comes into contact with soil, by being subjected to a vertical load, the two annular ridges move closer together locally.
