I have a slightly different perspective Steve. I wholeheartedly agree we should not have another spec formula nor should FF become a spec class. However, I do think the concept of a spec tire for FF would be a good thing. While we don't have sealed engines, the Kent is essentially very narrowly controlled and is pretty close to a spec anything in FF (Honda notwithstanding). its not really a formula (you can change wheelbase in a formula, you can't change displacement or rotating mass of a Kent in our 'engine formula').
However, while I think spec tires is best for most forms of racing and perhaps in concept for FF, my opinion is its not really feasible or beneficial for FF to have a spec tire, simply because its not practical. The most effective means to control tire costs is the limit the number of sets you can use. This limit then dictates the life required of the tire. In CART it was 7 sets per weekend, in F2000CS its 6 tires per weekend. In FF, if our goal is to use fewer than 1 set per weekend there is really no way to control where someone runs and how many times they were used before you go to your next set. So if the goal is to keep it to 1 set per weekend, thats essentially where we are now. No net gain except for we're going slower and swallowing 2 stroke oil fumes.
If we have a 'qualify on what you race' rule this actually ends up more expensive for drivers like me who can either due to being a bit off the pointiest end or because my car doesn't consume tires I can get 2 sets over 3 weekends. I can manage my tires such that on any given weekend I can race on the 1st or 2nd heat cycle and have at least one qualifying session per weekend on 1st or 2nd heat cycle. I have never felt under-tired with my tire rotation. Yes, the qual/race rule does prevent people who buy two sets of tires a weekend, but lets be realistic, who is doing it and how often? The runoffs? Maybe the top 4 or 5 of 24 cars at the sprints? Seems like a small problem in the grand scheme.
I lived in CART both during the 'spec' tire era and the Firestone/Goodyear tire war in the mid 90s. The Tire war was not fun...its really hard to sit and watch yourself fall to the back of the order because their tire didn't work that weekend. The spec tire averted the tire war, but in reality we don't have a tire war in FF. The GY & HS are pretty equal. Different, requiring a differing setup, but once optimized not really one advantaged over the other.
I do think that tires should be as controlled as the engine is; in CART, we broke track records when Goodyear brought a good tire or the field was slow when they misjudged. But it applied to the whole field. When we went tire testing with Goodyear (3 day test) we had the first day to get our car balanced. We spend a whole day with wings, rake, ride height, dampers etc to get within about 0.3s of the track record. The next two days we ran test tires and occasionally returned to the 'controls.' We were not allowed to adjust any setting on the car. We went from 2 seconds under the track record to 3 seconds over it on new sets of tires on each run. We essentially went as fast as Goodyear wanted us to go. Something that has that much performance influence should be closely controlled and perhaps even spec'd as close as the engine when its practical. But only leave the 'formula' aspects to the fine tune knobs on the car. However, in club racing I just don't see it manageable or beneficial over the haphazard schedule we can all attend races at if it just gets us to 1 set per weekend.
