Method for the treatment of single-filament polyethylene terephthalate cords for the reinforcing layers of a pneumatic tyre comprising (a) an adhesive solution coating step, wherein the single filament cord is immersed in an adhesive solution; (b) a drying step, wherein the cord covered in adhesive resin is held within a drying oven at a temperature of between 12° and 180° C.; and (c) a thermobonding step wherein the cord, proceeding from the drying step, is arranged within an oven at a temperature of between 23° and 260° C. for a period of between 30 and 90 seconds. During the thermobonding step, the single filament cord is subjected to a tension of between 8 and 12 mN/dtex.
