I'm looking at buying a second hand E70 pretty soon and am completely sold on the look of the 20" Y-spoke wheels. Problem is, we're really after a 7 seater which I'm pretty sure means you lose the spare wheel.

I'm thinking of buying a second set of second hand alloys off eBay and putting some winter tyres on those to switch over in the winter months and for when we drive to the alps skiing. That's quite a cheap option though until the requirement becomes winter runflat tyres.

So does anyone run without run flat tyres and no spare wheel? I guess I could always buy a space saver spare wheel and take it in the boot on long journeys but you lose enough luggage space with seven seats as is (but we would have a 500 odd litre roof box in those instances). I guess it's mainly just a case of luck.
