For consideration ...
As lap times decrease, tire wear goes up exponentially.
I certainly wouldn't expect consumables to last the same running a 25 at MSR-C as they did when the my FTD was (and still is) a 29.

I was kind of blaming the excess tire wear on moving to 17's.
I used to easily get 2 to 2-1/2 weekends out of a set, but since I moved to 17's a set shaved to 4/32nds now last 1 to 1-1/2 weekends shaved to the same specs.

I also think that my new set is wearing a lot faster than the two older sets that I have.
Being the suspicious type, I find it interesting that the increased wear due to lower lap times comes right after the release of the "new" RA1.
Edit to add: The Spec Miata guys are seeing the same thing:

The tire does not have to be fast if we are all on the same one. $1000.00 per 1.5 events just for tires could run some guys off. Until last year I only bought two sets a year. Of course I was getting five events out of a set of front brake pads and now just two.

If there aren't enough AI racers at the events, tire choice becomes irrelevant as no contingency is viable.Originally Posted by MikeP99Z
My comparison specifically listed 5-6 starters. Not 1-3 starters.
Does any of this REALLY matter?? I don't think NASA is going to sever ties with Toyo for AI anytime soon... Get as much life as you can with camber setting, tire pressure, flipping, praying, whatever...
I ran on take-off scrubs for the last 5 years, so I have NO clue how many weekends I will get on a set of RA1's. With MSR-H being wet, it was kinda hard to measure the wear...
After MSR-C we will see where I am. I'm hoping to get MSR-C and TWS on a set and go into Hallett with a fresh set and have them last until the end of the year... 2 sets over 5 or 6 weekends.

MSR-C is a bad place to judge tire wear. It is super smooth and easy on tires. The first year I raced CMC, we ran there 3 times (2005), out of 5 weekends, and I got a total of 7 weekends out of a set.
