Dont let them get above 32PSI Hot pressure. Typically there will be a 6PSI difference between cold pressure readings and hot pressure readings. In SUPER HOT summer conditions I have seen as much as 10 PSI difference. These will be a little quicker than GYSC3R tires but will last considerably longer. They LIKE alot of NEGATIVE camber. I run -3.7 front and -3.0 rear.

They will heat cycle out BEFORE you will see those wear indicators disappear so ALWAYS check them after a track day. I usually get 3-4 full track days out of a set.
You mention that they will heat cycle out before the wear indicators disappear. What exactly are you checking for after a track day then?

Wouldn't the grip just go away and that's when it's time to change them? What other queues do you use to know they are done? Wouldn't you just count the heat cycles?

Lot's of questions I know, I'm getting mine mounted tomorrow.

I get roughly 6 to 10 sessions out of a set. Depends on the track. When I see cords I change them.

Well I usually go by monitoring my lap times. If I know for instance I normally run 1.17 a lap and then it gets to where I am in the 1.18's to 1.19's then its getting time to change them out. Sometimes you cant feel the loss in grip but lap times dont lie. If you are running scrubs you dont really know how many heat cycles the tires had to begin with so counting heat cycles is not that accurate either.

Mine were written on the tire so I have a good idea. But thanks for the info, times is a good one to go by. I just got finished mounting the tires. The slicks + Apex wheels 18x11 are 20lbs! lighter than OEM, almost 22 lbs I think on the rear. From about 60 to 40. These are 325/660.
