Just remember the F1 is a summer tyre so performance when the temperature is <6C isn't the best.
....Well, since Friday I've driven 430 miles on GY F1 Asymmetrics with outside temperature displaying in the dashboard between -4C and +1C and felt no tyre/grip problems. My individual tyre temperatures have started off at 1C and risen to 15C (usually 40C in hotter weather). I haven't driven on snow though.
I'm not saying that the F1's are a winter tyre though - They're clearly not and winter tyres would be far better by all accounts but I am able to completely avoid driving in any snow or icey conditions unless I'm already on the road and caught out.
If anyone is wondering how I know this info, I have a TyreSure monitor installed which updates itself every 5 seconds and toggles automatically between individual tyre pressures and temperatures. A luxury but a bit of kit I now wouldn't want to be without as the info is very reassuring.
