Gone are the days when I would consider all aspects of tyre choice. Now with our roads in the present condition, with unbelievably deep potholes; driving in the dark, particularly when raining, is a nightmare. I run 3 cars, and fit mid-range tyres and drive accordingly. Moreover the CC highways, actually admit to using top dressing of unusually large and sharp edge material, and also admit that they rely on the traffic to bed down. Broken windscreens and chipped paintwork abound.
