Semi-hollow tire with specified profile and rolling member equipped with plurality of such tires
First Claim
1. A tire for an agricultural machine, said tire having an axis of revolution and comprising:
- a tread,a sole situated opposite the tread, andtwo sidewalls connecting the tread to the sole, wherein the tread, the sole and the two sidewalls together forming a casing defining a chamber inside the tire, wherein the chamber is in communication with the exterior of the tire via an orifice in said sole, said orifice preventing said chamber from maintaining an inflated state,whereinat least one of the sidewalls comprises, in this order and in succession in a direction oriented radially from the axis of revolution to the outside, a proximal portion connected to said sole at a radially inner boundary, an intermediate portion and a distal portion connected to said tread at a radially outer boundary, wherein in cross-section according to a plane including the axis of revolution of the tire in the unloaded state, said at least one of the sidewalls has a profile such that the intermediate portion is an axially inwardly projecting curved portion and the distal portion is an axially outwardly projecting curved portion directly connected to the axially inwardly projecting curved portion, said at least one of the sidewalls presenting an inflection point that delimitates the intermediate portion and the distal portion from each other,the intermediate portion projecting into the chamber in a direction parallel to the axis of revolution in the unloaded state,in the unloaded state of the tire in directions parallel to the axis of revolution of the tire, the minimum distance between the outer surface of the intermediate portion and the tire median plane is strictly less than the distance between the axis end surface of the sole and the tire median plane, andin the unloaded state of the tire in directions parallel to the axis of revolution of the tire, the minimum distance between the inner surface of the intermediate portion and the tire median plane is strictly less than the maximum distance between inner surface of the distal portion and the tire median plane.

Abstract
Pneumatic tire 1 for an agricultural machine, having an axis of revolution XX and comprising a tread 7, a sole 11 situated opposite the tread 7, and two sidewalls 13, 15 connecting the tread 7 to the sole 11. The tread 7, the sole 11 and the two sidewalls 13, 15 together form a casing 17 defining a chamber 19 inside the pneumatic tire 1. At least one of the sidewalls 13, 15 comprises, in this order and in succession in a direction oriented radially from the axis of revolution XX to the outside, a proximal portion 131, an intermediate portion 133 and a distal portion 135. In the unloaded state, the intermediate portion 133 projects into the chamber 19 in a direction substantially parallel to the axis of revolution XX.
