Hello, I have new Pirelli P Zero Nero in the dimension 235/45 R17 97W on 8.5×17 Advanti rims. A wheel has a slight (!) height strike visible on the force machine and requires relatively many weights on the outside (65 g, inside 0 g) even after matching. It is also easy to hear when driving and there are slight vibrations to feel. But really only the noise bothers me. My tyre dealer now offers me to buy a new tire and the old one (n If Pirelli acknowledges the error, they would reimburse the new price. Has anyone ever done this before? How kulant are the tire manufacturers here? We are talking about a visible slight height strike as said. What are the permissible tolerances? Greeting Achim
