Winter Wheels
 

I'm looking for some advice on winter wheels. I currently have an A6 2008 Le Mans 3.0TDi Quattro on 19" Michelin Pilot Sports. I am looking for some winter wheels and have gone to the old favourite Ebay. I have seen a full set of 17" which have come off an A6 Allroad, I'm currently waiting to get some more details on the car they have come off.

The alloys look ok (Not quite as good as the 7 double spoke I have currently on), and the rubber looks fairly fresh, but will get a better look before buying. But what I need to know is should these fit my A6 or do I need to get anything else checked? I know I was looking last year at some of a different model but would have needed to get some spacers for the wheels so I didn't proceed.

Cheers for any Advice.
