Steve, calm down. In hindsight I can see how you have taken this badly, lies was just my way of saying I disagree. Had 2 sets of F1s now and both (all be it the second set havent even done 1k yet) have been brilliant (apart from in the snow). Great in the summer and have not come across any issues when using them in the winter (again, apart from in the snow, but what "normal" tyre is).
