Stock tires, lots of tread no grip

Sorry if this topic has been discussed.
It looks like I got lots of tread on the stock tires, but my last 2 track days, and worst the last one, the car was all over sliding. I have 4 track days and quite a few road miles. I have heard about heat cycle, which I would say these tires have gone through at least 9 times. Are they done?
It was frustrating driving the car, it seems I had better grip on my last m3 with super sports.
Edit: just hurts to see the amount of tread that is left, but have to cough up 2k for new tires. Another thing I did not mention, the cars seems it is driven on rocks. I thought I may suck in driving this Porsche, but it over steers under throttle, frustrating.

As the hardness goes up the grip goes down. Anyone tracking should buy and use a Tire Durometer to measure Tire hardness.They are not expensive with prices starting at $25.00 on Amazon. That will take the guesswork out of when to buy new Tires, and YES - Road miles also play a role although not as large a role as Track Miles since the heat buildup will be less. My MPSC2's Tire pressures
rise 3-4 PSI on roads and 6-8 PSI on Track - all caused by heating. The Durometer
will also pick up Tires hardening with aging over time, even if unused.

durometer
Hey Fastlaneturbo,
Do you use a durometer? What are the differences you are seeing between new tires and heat cycled out tires?
I am curious because I do have one and have not seen a lot of difference in hardness and maybe I am just doing something wrong.

So in the end, I went with the MSP4S. After burning up the P-Zeros. A few reasons why. I just felt that getting the sport cups up to temp would be difficult or impossible on the street, and that does not suit my driving. Also, driving P-Zeros that were almost out of Tread was fun. With lower grip I could feel the car move at subsonic speeds. A little bit of controlled sliding is good for the soul. I could drift my 1981 VW Scirocco S below the speed limit. I don’t have an opinion on the new tires because I am responsibly breaking them in but I’m sure that I will not need more grip than available from these for daily driving.
