The Toyo RR's were brand new at the start of the weekend. This was the last race on Sunday afternoon after 3 practice sessions + 2 qualifying sessions + 1 race = total of 6 heat cycles before this race.

What lifespan are you experiencing on the RRs? Is 6 cycles typical, or was it a hotter than normal day. It seemed that you were not expecting the behavior (at least that's what I took from your comments in the video).

I think that it was driver inexperience, not the tires!
With that being said, I have found that a new set per weekend is required for me to place in the Top 5. The tires last well beyond that but my speed starts to fall off. Yes, I am probably using new tires as a bit of a crutch.
A better driver would be able to compensate for the tires as they wear and keep times up through more of the life of the tire. I aspire to be that driver by year end!
Brad, can you weigh in here? What is the typical number of HC's that folks are seeing?

8 HC's.. they are done for the amateur. A pro *can* turn the laps on 20HC tires.. (I had David Murray in a SPB a few weeks back turning fast laps at VIR on 28HC tires)
I know how to keep an amateur moving on them at a good pace with a high number of HC's

FYI: I can only make them last if you are running square (which 99% of the country is doing) it doesn't involve flipping them or doing anything crazy.. and it makes ZERO difference where they are located on the car based on "serial number" .. all horshesh_t...
