Hello again, either this did not work with my question or it has disappeared. Please allow me to ask the question again. Should one use the information of the REIFEN manufacturer to air pressure or that of the VEHICLE manufacturer? Tyre size is 255/35 R 19. Goodyear recommends for the Eagle F1 Asymetric 3 on an A4 Avant Facelift B8 the air pressure partially loaded front AND rear 2.6 bar, fully loaded 2.8 bar. Is in my opinion already quite unusual, the same Lu I’ve never had that with a car before. Audi says 2.9 in the front and 3.1 in the rear. How much bar do you advise me? I’m usually only partially loaded. I’m very grateful for your help.
