One of the intents of our rules (as listed in the 2019 rules) is to limit costs, I feel like with stickers at all or at least most events we're missing that part these days.


Looks like the alternative options will be the Nitto NT01 & the Falken Azenis RT615K+ & the TOYO R888R (one article suggested 12-15heat cycles was the end of 888R's).

I reached out to the Spec Corvette guys to ask them about their experience running the Azenis tires (Class mandated tire for Spec Vette). They said they're getting 4 race weekends per set, no falloff and are as fast at the end of the 4th weekend as when they start. This was the closest to parity to CMC that I could find, in that its not a miata or other lightweight vehicle, makes decent power, and is running sprint races...

Aggie doing math -- your mileage may vary:
We have 7 events this year assuming ECR comes back later, retail cost of new RR's (28 total) for each event is $7336 before you factor in contingencies. Or 73.4% of the street value of my racecar (being optimistic) I went through some 'tire budgeting' math and it gets better, but still not great -- If I ONLY put good tires on for 6 sessions per weekend (2 quals, 4 races) I'm down to a total of 42 heat cycles on 'good tires' or 3.5 sets assuming I pull them off at 12 when they turn to stones. If I skip an event to save cost, I can see doing it in 3 sets at a tire cost of $3144, or 31% of the street value of my racecar. This doesn't factor in friday practice days on old tires that result in setup changes based on bad tires, etc...but you could squeeze it to $3144. Would it be a 'competitive' effort against someone showing up with new tires every event? Probably not, then again maybe you win some contingency and knock that down and buy more tires.
