Aluminium wheels 18"

(b) in the case of the following:

does anyone have any idea if you can grab 18 inches of rims on the v8?
which are the max. sizes without having to fry or pull on the wheelboxes...and up to which size does the tuv go without hesitation?

....kann ja sein ob jm,and ne 100% ige aussage treffen kann!
with my '90s it was like that...there I am to the tuv...and the chuate in his computer....searched the car guy out and the max. registered rim size with the corresponding mature and said: "....9x16 ET 35 with max. 225 can you do it WITHOUT having to make a full acceptance....can only be checked freely and done...."

....it would be really cool if someone knows each other or even works at tüv


thank you very much in advance....
