This year I thought I'd try winter tyres on my old 16" wheels so I took off the 18" 108s with Contisports and put on the 16". So I now have Dunlop SP winter sports on the front and Goodyear Ultra Grips winters on the rear. They've been on for about a month now and the temperature lately on most journeys has been in the 3-8 deg range. I know they are marked M&S but on cold damp roads I haven't really noticed an improvement over the Contis especially at the rear. Will they only come into their own in snow or would the Dunlops be better on the rear?
