I've gone for 189-style with OEM size Falken HS-439s (225/40/18 and 255/35/18). £50 for the wheels, £160 refurb in gunmetal, £440 for the tyres from mytyres.
It's all about the better suitability for sub-7degC temp driving conditions for me. We still got a lot of snow last year (Scotland, house being 170m above sea level in the countryside) but it was nothing compared to winter 2010:
(the snow is higher than the car...)
