To be honest Ian a tyre rule wont really matter as 99% of the people attending will run staggers and mini pins.
I wouldnt enforce a tyre rule as alot of people want to use up old worn out yellows from outside that still work pretty well on carpet and makes the racing cheaper and will bring more people through the door.
I would just open the track up and let the people come and race, us off roaders don't like too many rules, we are a bit more chilled than the TC brigade!
