Can anyone help me on this one?

? Here's my story first.....
I change my Golf every year (ordered my new one today). When i re-import it to the UK (cos i live abroad) to sell, it has to have a minimum of 4000 miles on.
I've had my current golf since december and it currently has 1196 miles on it - this is because 'i am a skier'
Here's the deal - in Germany local law states that between oct and march (or when ave temp is less than 7 degrees) cars should be fitted with winter tyres. This year i chose not to do this and just garage my golf for 4 months as i spend 3 months over winter away in austria/france/switzerland (using a german car with winter tyres).
However, due to the lack of milage on this years car, im taking the next one on my travels over the winter.
What tyre size is going to work on the Gti?

?? The norm is to drop 2 inches when switching to winter tyres. However VW have simply said 'stick with 17's or 18's - not much use to me when the tyres are €208 each!!!
So, will something like 16" alloys (225/45/16 tyres) work??? I know 16 inchers will look gay - but will they work - will the car slide around everywhere through not being able to distribute power correctly?

?
thanks guys!
