I was with my fat guy at the TÜV. In advance: I put boleros from the C4 on and balanced the wrong ET with 10 mm distance discs per axle.
My tire man put Pirelli P Zero Rosso on me in the dimension 235/45 R 17 94 Y. Is sensational compared to the 15" gullies

Now my problem:
The production tires for the boleros are 245/40. Roll-off circumference 1915 mm.
My 235/45 have the roll-off range 1965 mm.
According to Adam Giant, this is 50 mm difference.
The man at the TÜV said that the roll-off circumference is too large for the car, the brake is overtaxed ... However, he would still inform himself.
(before that he said that the V8 could also be ordered with normal disc brake and he did not apply the hood.)
Now my question:
Is this really the case that the brake can't handle the roll-off circumference? And why is the roll-off circumference so critical when it's the same front and rear? I mean pure of the driving feeling, in my opinion, the brake has no problems with the tyre/wheel combination.
Headshaking
