Driving comfort 18 inches rims with 255/45 R18 103 y

Hello together, have now since the middle of April my 18 Zoller Inovation on the thickness with the 255/45er and find the faghr comfort despite the air suspension absolutely modest.? especially on bad roads which have liked to have been patched or not. on track it is O.K. rubbers are new on it Goodyear F1 Asymetrico. In contrast to the 17 Zollern with 235/55 I find it considerable. Is this normal with the thickness.? With my last Touareg I had 19 Zoller with 275/45er there I could not have a bus If that should be really normal, the 18 customsmen go to the bay to auction and sh…. what about the look and put the 17 customsmen on it again. I would be happy about an info. Greeting Jörg
