By the way.......going back to the Amco Mini tyres. I am not sure what these are. A CR65 has a much narrower tread than this.....could they be a slick with some radial grooves in them ?? I will ask Rod when I next see him.[/QUOTE]

Very good. I would like to see a comparison with a 10 inch Dunlop slick. What size wheels are these for. Is just the small one a 10 inch.
This is only a reference guide for Dunlop Tread patterns of the day. I know that the 65 and 81 patterns were available for the 10" but outside of that I'm guessing.
No doubt about it. The CR65 tread on the Mini was great. Had a half worn set on the car when we bought it in 1984, and even though they were old and hard were still streets ahead of the current stock of DOT radials.
There are 3 reasons why I think this issue should be considered, discussed then once decided we can all leave it alone:
1. Anyone leaning really hard on DoT tyres will tell you that tyre life/ temperature is an issue. An issue made worse by small tyre/ wheel size (eg AMCO Mini), high horsepower (ask any front runners in the BMW Class B) and high temperatures. I have cut out a brand new set of 4 DoT tyres in one January Taupo meeting (3 races).
2. These cars DID run on slicks both here in the BNSW series etc and also Group 2 ETCC. Getting a comparable DoT tyre size can actually be quite hard as witnessed by the Haliday Escort and AMCO Mini (especially in 10 inch).
3. There is an opportunity to equalize the lap times of the HMC/ HSC field which will only add to the spectator appeal of these classes. For those HMC drivers who do not want the "Star" quality of their cars to be diminished, the finish line is always at the end of the straight anyway!
Before anyone assumes that this argument is about personal advantage, unless my current plans fall over, I will not be running in the class for the immediate future.
