I'm currently looking at changing the daily, an X3, which my wife uses for work and can't decide if we should continue with a 4x4/xdrive. We've had plenty of BMWs over the years and all were terrible in the white stuff but I've never tried fitting winter tyres. We live in a semi rural location that gets little gritting so it is a real consideration for my wife's next car. Would you peeps that run them say they make enough difference to not need four wheel drive to be confident in the winter?
