I put 18" Vrederstein Wintrac Xtreme non-runflat on my JCW four years ago and have left them on all year, excellent tyre.
I don't agree about 4wd not being necessary, If you travel on narrow country lanes you can get pushed off into the deep snow at the edge (usually by a Rangerover hogging the middle) and one spinning front wheel doesn't get you out.
