Abstract
Tire-type device having bearing elements () within annular space () between inner and outer coaxial structures of revolution, the latter contacting the ground in contact patch (A). The bearing elements are independent in pairs and buckle under compression in contact patch (A). The smallest characteristic dimension E of the section S of any bearing element () is at most equal to 0.02 times the mean radial height H of the inner annular space (), the surface density D of the bearing elements () per unit area of the radially outer structure of revolution, expressed in 1/m, is at least equal to Z/(A*ΣFr/n), where Z is the nominal radial load, expressed in N, A is the area of contact with the ground, expressed in m, and ΣFr/n is the mean force at break under tension of the n bearing elements made to buckle under compression, expressed in N.
