A tread for retreading tires, having an external face (21) provided with the usual grooves (23) and an internal face (22) to be seated and adhered, usually by vulcanization, to the convex external face (11) of a tire carcass (10), from which the compound of the original tread has been totally abraded, said tread (20) presenting a thickness that varies throughout the width thereof, having its internal face (22) defined in a concave arc, with the radius of curvature corresponding to that of the external face (11) of the tire carcass (10) and with its external face (21) being flat or slightly convex, with the radius of curvature substantially larger than that of its internal face (22).
