Tire for heavy duty vehicles

摘要

Tyre structure with radial carcass reinforcement for heavy goods vehicles and, in particular, tyre bead making it possible to have, on unmodified wheel rims, side walls the radii of curvature of which are sufficiently large to prevent premature fatigue of the reinforcing elements which constitute the carcass as a consequence of the flexing cycles which are generated by running along. The said tyre structure includes at least one bead wire (2) situated radially on the outside of the lip of the wheel rim (J) and around which the fold-back (1') of the carcass (1) is formed.
