Winter wheels and tyre choices - Exige V6 - Am I mad?

[TheAdWrighty]

I might be doing the stupidist thing ever but want to give it a shot anyway! I'm the new owner of a V6S Roadster, currently has the standard P Zero Corsas and I would like to run it through winter (or try to at least). Naturally with having 265 rear section tyres and not all that much weight, it's going to be terrible in the cold/snow!

So does anyone have any experience, reccomendations or good info on wheel and tyre setups for the winter. Will elise wheels fit straight on? (with a spacer I would guess)
