19" alloys

With the 8.5J it might stretch out the tyre a little but 255 id say is too wide, you could do with 235. I used to have a set of RS4 Reps that were 8J with a 235/35 tyre and no problem fully loaded at all on my Standard sport suspension. They were ET38.
On my Blue car, I have 8Js with 235/35 but offset must be different because I was fully loaded last week and I got a slight rub when tackling a speed hump the same way I used to in my red one with the RS4's on.

With your being ET45 then its pulled the alloy in a little but with the 40 profile and the 255 width then your going to have a fatter wall compared to mine.

What alloys are they and what they off???
