Can you run different width (225 & 235) tyres on an A3 Quattro?
I'm running 19" 8.5J Alloys with 225/35 tyres all round on my A3 2.0T Quattro so there's a bit of stretch. However, I got a bad puncture the other day and need to replace two of the tyres. I wanted to take the opportunity of fitting a pair of 235/35s as I'm positive they'll fit (and will offer the rims more protection) but the garage has advised all four tyres need to be same size.
I don't want to replace all of the tyres as two of them have loads of tread left. I can understand you not having different size profile tyres as I guess you could potentially have the front and rears rotating at slightly different speeds but I'm unclear how having a 10mm wider set of rear tyres would adversley affect the car.
Any guidance would be greatly appreciated!

By the sound of the replies you've got, this type of thing is okay on Haldex, but just in case an A4 (or above) owner picks up on this thread, I assure you it is NOT okay for Torsen differentials: 3.5mm difference plus 3mm in tread difference would massively overwork the rear diff and cost a grand or two for the sake of two new tyres.
Check in your log book or with your local Audi dealer if in any doubt.
