Guys,
I think we can all agree that the Toyo RR has perceived “issues” with lifespan. Toyo only provides a very minimal contingency that doesn’t get even close to supporting the tire budget for anyone other than the winners. Here is a thought…
“AIX – Heavy” (AI Cars)
“AIX – Light” (CMC Cars)
Cars that are running an “open tire” class with a gentlemen’s agreement to follow their parent ruleset. We can agree on a commonly available DOT tire that can be used in lieu of Toyos. The idea would be to get a tire with less total grip, but a longer lifespan. We could use a rule for a minimum treadwear (150, etc). This would allow folks to possibly run a set of tires an entire season and not worry about the effects of heat cycling.
Granted, there would be no Toyo contingency, but your total tire bill would be less than if you had used Toyos.

For the trophy girls:
Toyo RR ($1100/set) * 3 sets per year, assuming two weekends per set = $3,300. If you get an average of $300 per weekend in contingency (winner of a 7+ field), you would have $1,800 in contingency. That would put your total tire budget at approx. $1,500 per year. A decent 275/40 17 tire (Kimho Ecsta XS) would run $200/tire ($800 per set). Assuming one set per year, you would save $800.

For the rest of folks who stretch tire life:
Toyo RR ($1100/set) * 2 sets per year, assuming three weekends per set = $2,200. If you get no contingency, it would put your total tire budget at approx. $2,200 per year. A decent 275/40 17 tire would run $200/tire ($800 per set). Assuming one set per year, you would save $1,400.


We could still do the same split grid, based on sub-class. Points would have to be figured out, but if that is the most difficult part of the equation, we are miles ahead.

Think of this as a baby version of the AIX outlaw class on the west coast...
