So, last winter I struggled in the snow but got everywhere I needed to (I live at the top of a medium grade hill). I had a FWD car at the time with 225 tyres on the drive wheels. This year I have the E350, with 265/35/18 tyres on the drive wheels. So, I have decided that before any snow hits and tyres or chains are hard to come by I will try and get the necessary. I considered auto socks but they don't do them in the size I need. So I looked at chains (not ideal as only the hill is a problem for me). Found these (Thule K-Summit XL - Thule - Thule RV Accessories - Tire Chains) which look pretty good and easy to get on and off as needed so I can put them on at the road-side if needed. They are about £300 a pair. So after rambling, my question is, would getting a good set of winter tyres be as good as these or not? And does anyone have a better recommendation? If I get tyres I will have them taken off and swapped in spring for the normal ones again.
