Tyres with radial reinforcing elements and at least two sets of circumferential reinforcing elements (2) in the flange which fits onto the rim, in which the radially lowest part of the axially outermost set of elements (5) is radially higher than the lowest part of the adjacent set (4). Tyres with sides ending in flanges designed to be fitted on a rim, with a carcass framework (1) through the sides and joining the flanges. At least one of these flanges has (a) carcass reinforcing elements going from the lower radial part of the flange towards the edge and (b) at least two sets of circumferential reinforcing elements (2) running next to the carcass reinforcing elements. In these tires, the radially lowest part of the axially outermost set of elements (5) is radially higher than the lowest part of the adjacent set (4). An INDEPENDENT CLAIM is also included for tires as described above containing materials such that e1j is the thickness of each product which radially separates the radially lowest turn of any set of elements from the bottom of the flange, e2j is the thickness of each product which radially separates this lowest turn from the axially internal face of the flange, and G1j and G2I are the respective Young's moduli of the above products, where these materials comply with the following expression. ìe2i * G2i = je1j * G1j - |
