Although I haven't made it clear, my comments on this thread are in the context of kit car classes at speed events (sprints & hillclimbs) where I have been a regular competitor for many years. In this context it should be considered that (a) List 1B tyres are the preferred by the majority of non-competition users for these cars - people are put off by having to spend more money on inferior rubber (and extra wheels) for competition use; (b) a lot of these cars are supplied from new with List 1B tyres (and that is a good reason to allow them in competition); (c) A set of radial List 1B tyres will easily last a season - the guys at the front will change their List 1A tyres every season anyway.
I wouldn't be so arrogant as to issue any would-be edicts for other types of car or other disciplines of which I don't have extensive experience.
