1. Deformable wheel comprising : - a rigid hub (2, 10), - a tread (1, 11-15) which is radially deformable, but whose periphery is substantially constant in length, - connecting means (3, 16, 19) which connect the hub to the tread, those means being able to radially stretch when being tensionned as the wheel being loaded, but resisting only weakly to a radial compression, - means able to maintain the gaz pressure inside the wheel to a value equal or slightly higher than the outside pressure, - means which allow the wheel to operate as the gaz pression is at the said value, characterized in that said means which allow the wheel to operate as the gaz pressure is at the said value, consist of the fact that the radial stretching of the said connecting means (3, 16, 19) when tensionned as the wheel is loaded is less than one tenth of the radial length when unstretched.
