Abstract

Tyre has a carcase with one or more layers whose cords are placed in radial planes or form small angles with these flames, the tyre, when it is not mounted on the rim, having in transverse section an interior profile whose part extending from the tread to the lower limit to the sidewall has its concavity facing the interior of the tyre, the part of this interior profile between the lateral end of the insert between the carcase and tread and the lower limit of the sidewall being situated at a variable distance from the axis of symmetry of the tyre. The distance between the different points of the latter part of the interior profile and the axis of the symmetry is greater at the corresponding point to the lower limit of the sidewall, the ratio between the distance from this point to the axis of symmetry and the distance between the corresponding point of the interior profile of the tyre mounted on the rim and the same axis of symmetry being above.
