As long as all 4 are the same, then the quattro system will be fine, though your speedo will be out a fraction.

Lee, Richard, Thank You

Reason I'm asking is because there is a diameter difference between most of the OEM sizes.

Lets say stock is 255/45/18
If you use any of the following, 265/35/20 # 275/35/20 # 275/30/20 # 255/35/20, the actual diameter is between -7mm to +14mm from the diameter of the stock 18" wheel which has 255/45/18 tyre fitted

Sounds like 275/35/20 is the way to go.

Change of diameter only affects speedo/trip counter by a little, so as long as all 4 are the same, then there's no issue.

I would concur with that. The speedo difference would be small and as long as all 4 tyres start out the same, then, wear aside, you will be fine.

Cheers guys, very much appreciated

Yeah, I wouldn't put different tyres on. I may actually see how much extra I can get from the fronts after tracking and then I will just put a new set as I always do.
I'm thinking about 265/35/20, but there isn't much choice in this size, so may have to go with 275s, but they look a bit weird, unless the ones I've seen on A8 were on 8.5J.
On the other hand 265s may still wearing quick on the inside so I may have no other choice than 275's
Thank you once again for all your input

I think my wheels are 9J and I run 265 P-Zero's and they are just about spot on fit and look wise (too my eyes any who...)

Guys,I've noticed just today that the worn out part of the tyre is showing up carcass, am I right? See attached
If so that's not only illegal but dangerous as well, correct?
