Question for the DE guys who run Hoosiers?

Race Car
I target 30 hot for PSC's. I don't like to start them really low though so I still start in the mid 20's and come in 1/2 way through my first session of the day and bleed down to 30, then bleed again as needed throughout the day.

Stop with that 30 heat cycle thing. It's BS PERIOD end of story
30 psi only works for dirt tracking which I understand meets your criteria perfectly
I start (or started RS now gone) at 22 psi rear 24 front. Come up to 32 all around and play with air when I come in to manage 32 all the way around the rest of the day (always letting out more air as the day and track gets hotter).
To run 30 psi you'd have to start at 19 or 20 and be very careful with tire warm up to keep the tires from moving on the rims and 30 might be a little low for car control and grip but I do have love and respect for your thoughts so if and when I get another RS I'll give that a shot but I know I'LL NEVER EVER GET 30 HEAT CYCLES OUT OF ANY TYPE OF RACE TIRE, that's over 7 days and it's not going to happen. 888s won't last me that long.
PS I want videos of those 30 heat cycles

He will tell you the grip falls off
His car does weigh a little less than ours

Pads, gas, travel etc.... if I'm out there I'm not going to dick around.

I'll be running some c51s next weekend and will put this strategy in place

I tried running some used hooters at nola this past weekend. They had 20 HC's on them. Came out at 25 all around in the first session, ran a few laps, came in again and had Izzone bleed down to 30psi all around.
It felt as if someone had slathered my tires in Pam Zero grip, but I had a ball trying to keep the rear end from chasing the front end. I'll throw some video up next week. I was way faster on the Mich SS's I was running the day before. In fairness to the hoosiers, the track was uber slick being brand new.
The tires can be def driven on, but the performance is nothing like when they are new. As long as you slow yourself down, there is still some fun to be had on them. I still don't know about me personally getting 30 hc's, as my driver's side rear was so worn the two grooves were completely gone.

In the GT3 the rears are bald after 16 HCS and the grip is gone. I bought 3 sets of rears during my sort ownership and this car EATS rear tires. If I went over 20 HCs I'd bet they'd be corded and dangerous. I'll repeat this car is too expensive to drive, own etc... to waste time on ****ty tires.

Agreed. It was a new track with tons of run off so it was a safe condition to try it out. I'm not sure I would be so bold at Sebring. They were fine as long as you slowed down and drove an appropriate pace. If you don't mind driving slower they are viable.

depends on the ambient temp that morning.
I just take a WAG. When were at Road Atlanta a few weeks ago and it was in the 30's I overcompensated and started at 25/26. At end of session with less than 1/2 lap cool down (under 1 mile) I stopped on pit road and took pressures. They were a little higher than expected at about 33 to 34. I immediately dropped them to 29. Next session it was warmer and I checked after on pit road, 31 all around. So I dropped to 29.5. Next session 31. Dropped to 29. Next session came in at 30. By end of day it was in the 50's and windy.
the next morning I started a lot lower 21/23 and when I came in it was 30.5ish.
so, depends on tempature outside. On really warm days 70/80's I will start at 20/22. If I ever have to start in the 90's I will probably go with 18/20.
Lower temps don't scare me a bit. When I raced oval, we started left side at 10 or 12. It is just a matter of warming up CAREFULLY until get heat/pressure build-up.
I notice a lot of cars flying around too fast in the first few laps, I cannot do that with low pressures. But I know in 5 or less laps those cars will be over-pressured and I will wiz right by them.

I have over 20 cycles on this set (Hoosier R6). Been swapping/flipping. Still have equal wear bars across each tire. Grip is less than new but still better than any street tire.

R6 is 16HC on GT3, more than that is driving style dependent, but I won't push them beyond 20.
A6 are half of that, 8HC at most, pushed to 12HC with easy driving.
After what I saw at Sebring with the C51 in a 2012 Boss 302, I won't consider them at all. I should have taken a picture.

NO worries I've driven on the C51s many times at VIR and IMO they are the best tires made for the money.

Hopefully that was the case and fortunately (fingers crossed) I've had good like with the Hankook tires.
