Hello, new here and only been BMW owner for a few weeks. Advice please. For the purpose of towing the heavier caravan we just got, a little too heavy for my Alfa 156 2.4JTD, we purchased a 2008 320d Touring SE Edition M-Sport. Now, SWMBO will use this mostly and being a nervous winter driver, we want to fit winter tyres - which is a good idea anyway. But I don't want to be taking the summer/winter tyres on/off alloy wheels. I think a set of steelies for the winter with higher profile tyres is my preferred option, then I can just swap 'em over again in the spring and put the other set in the garage. Current summer tyres are 225 x 17 front and 255 x 17 rear run flats :huh: I'm not looking at M&S tyres but proper winter tyres. Any advice on my options would be welcome. Thanks Jerry
