So I mounted up the Hoosiers on the 19" Forgelines and ran them on my 19 RS. Everything ran well no issues with PSM or any problems at all. My question is although all went well I'm still learning the car and not pushing the car too hard. I've now had 3 track days on this set and they still show tons of tread. These now have 12 sessions on them, I've always heard that 12 heat cycles is all you can expect from R7's. I have another set ready to mount up, but should I? Can I continue to run this set, they felt great the last session I ran last Sunday. I have a new set of Nankan AR1's on the stock 20/21 set that I can run if the R7's heat cycle out. I have a 3-day track event on the 26-28th. Just looking to get the most bang for buck out of the tires, but I do like grip. What's the best call?
You can run them down to the cords if you want. We rarely run more than 10 cycles on our Hoosiers, but admittedly they don't cycle out in performance, just simply wear out to the cords. In a heavy street car cording is not a great thing, you already take a lot of risk on the track so be careful. When I ran Hoosiers on my GT3 the most I dared run was 15 cycles. You can measure wear on the tires to judge how close you are to the end as well.

surprisingly they show very little wear, I attribute that to not pushing as hard as we could. I say we because both me and my wife are driving this car. I also have a 2009 Cayman S that is a dedicated track car. My wife’s times in the RS are slower than she would do in the Cayman. She is a very good driver, but she’s a bit intimidated by all the power, and the rear engine, and the 250 K price tag. We’re going to ease into this 911 GT 3 RS thing. But I think these tires have quite a bit of life left in them.

I was told that I should take these to my tire shop and have them flipped on the rims. A friend of mine who is a long time racer, although he is a BMW guy. Said that’s what he does, and it works well. So I think this is what I will do unless someone has a very good reason why it’s not a good idea.
So I received my next two sets of tires. As was recommended on this board I'm going to run 295/30/19's F and 345/30/19's R. Man these things are meaty. Everyone says they will fit, I guess I'll find out. The Tires I've been running are 315 and 265's. I have a set of Hoosiers and a set of Toyo RR's. The Toyo's were on closeout at Track Day Tire. I will mount these after my next event. Below is a picture from our event last weekend. The Cayman is my dedicated track toy.
I've run the R7's for many years on this platform (RS/GT3).
At 2 days - make sure that you rotate the tires left to right side. Often this is all that you have to do.
I used to flip tires on the rim all the time but have since proofed to myself that just occasionally you'll want to flip the left rear.
I always saved the R7's that were 2 or 3 days old and would do the next morning's first 2 runs and then put your fresh tires on for the afternoon.
I've corded dozens, if not hundreds of R7's. It's the rear inside edge which is catastrophic and most prone to failure. If that rear inside edge is "flattened" after 10-12 runs - don't run it anymore.
Within the picture you have attached I see what appears to be cut marks and complete loss of rubber on the left. Explain this wear on the tire. Also would this be normal wear after 10-12 heat cycles with stock camber in rear? Newbie here, thank you. ~ Question is for "sasportas" or any others willing to chime in.

So we ran the 295/345’s. My wife Rita ran the car all weekend. We were at Wild Horse Pass Motorsports Park running what’s known as the Mondo track. 2.3 miles that incorporate the Radford Racing School (formally Bondurant, Rest In Peace Bob) course and WHP Maine track. She really picked up the pace and is driving well. One of our club members drives a highly tuned M4 and he clinched the Hot Lap title for the year at this event. Rita did not compete but she matched his times in the DE session. I on the other hand I found a my way into a tire wall with my Cayman. So I’m sad, I will build back better. I didn’t make that phase up, I stole it from somewhere.
Oh, the Hoosiers were awesome!
Just wondering if you have PCCB’s on your RS, I have a set of 19” Forgelines, I haven’t tried them for fitment on my 19RS wasn’t sure if they would fit over the PCCB’s or not
