ABSTRACT:
Tubular tire for motor vehicles, of the type including an inflatable tubular inner (pneumatic) tube, a bracing, a case of the radial type, a rim strip, some rubber sides, a tire tread and two semi-rigid circular rods. The two rods 7 are set at the level of the bracing 2 at the edges thereof; the rim strip 4 has a width included between approximately 0.25 L and approximately 0.35 L; the transverse section of the tire has an H/L ratio included between approximately 0.5 and approximately 0.6; the sides 5 of the tire have a profile corresponding to that of the top part of the curve which represents the equation of a classic radial tire; the aggregate is such that, seen in transverse section, the tire fairly forms an isostable triangulated system.
