Well, I've had a week with the winters on, and that was interesting. We had snow, quite a bit, and as expected the tyres were great, but blimey! they were a bit " lively" for the first 500 miles or so. I know there's a coating on new tyres and they have to be run in quite often , but it wasn't nice for a few days. I've put a good 700-800 miles on them now and they are fine, but a warning to all. Take it easy for the first few hundred miles.
