i run my sportback 5dr with s-line 18's 35 front and 33 rears....

To confuse matters further, my A3 sportback recommended tyre pressures were 38F/35R.
Anything less than that and you noticed the handling going stodgy.

I needed a new fuel flap under warranty.
The dealer gave me the car back with a sticker for 17" wheels....
