Sorry to resurrect this thread again, but I had an amusing and enlightening experience today; went to the local country park to walk off too much food, and discovered that off the main road, the plough hadn't been through and there was a good 8-10" of lying snow, more or less undriven. Except for the big Audi Allroad that was ahead of me, with all four wheels spinning wildly. A group of us pushed him out of the worst of it, and I noticed that the car behind me was spinning wheels too. Drove the Golf steadily forward, with the chin spoiler acting as a snowplough, and didn't have a moment's wheelspin. Suggests that winter tyres (Falkens on the front, slightly more worn Vredesteins on the back) are a better bet than 4wd and summer tyres!
