How does a FWD DSG wearing summer tyres pull away in snow?
ESP off, initially let the wheels spin, then come off the throttle. As the revs drop as the torque drops off, wheels will move a little, before it stops do it again and repeate until there is enough momemtum to keep rolling. If there is a corner or obstacal ahead, just hope and pray that your summer tyres will steer you around it, rather than slip and slide you into something hard.
Having successfully negotiated all hazzards in a manner that you have for the last 30 years without too many problems, return home and fire up your computer. Use ebay to buy a second hand set of OEM wheels and whilst you are waiting for them to arrive, ring round your trusted tyre dealers and see what winter tyres they have in stock. No need to spend £150 each on what the magazines or internet experts tell you you must have, 'lesser' brands will do just as good a job providing that you drive according to the conditions. Let's face it, there's no need to do a Sunday morning B road blast just because the roads have dried and warmed up, so your new winter tyres will do just fine for what the motor car was designed to do. Getting you from A to B.
Leave your winter wheel package on until the spring, give them a clean and store them away until the next Novemberish time. When you have done with them, or sell the car, simply sell on your wheels and get your initial money back. Granted, you won't get any money back for worn out, secondhand winter tyres, but then they will have done their job, as well as saving your best summer tyres from wearing out too.
