    235/40's are the standard B6 18" tyre size.

    Yes it will, it will sit approx 6mm further out in the wheel arch than the standard ET43's. As such you may get away with 245 section tyres, but would need to adjust the aspect ratio to keep the rolling resistance the same.

    I'd stick with the 235's myself :icon_thumright:

    im running 8.5j pcd112,et35 with 225 / 40 /18 the 225 gives a slightly stretched look so as james says 235 wiil be the ideal tyre, 245 will bulge a little and wouldnt look as neat.

    Did you fit them to the car to know they look better? Wider tyres will always look better I guess. Personally i'd stick with the 235's as I reckon any wider and you would suffer increased tramlining and aquaplaning.

    What size are your existing tyres? Remember to keep the aspect ratio within limits for the quattro.
