What kind of durability/usable heat cycles for practice ?

F1CrazyDriver

New or used ?

New just as much as hoho r6 but optimal grip gone after 2-3 heat cycles. By optimal I mean max grip (2 sec faster than r6)

After that equal to r6/nt01 grip level. I use them 4 track days(4 sessions per day). They can last longer depending on driver. I have meat but I toss after 16-18 hc . I don't track much so they last me a year +. Feel is amazing you will never want to go back to hoho/nt01 , so double check your crack addiction before trying.

I don't drive fast either so if fresh tires I expect you to get 20hc in practice mode. Given that my above paragraph is based on a 996t. Gt3 I have little experience w pirellis. Only done 2 track days in last 16 months. No time to get out there. Gt3 is lighter and less tq to punish rear tires from my experience.

I have 245/645 for the front and 305/680 for the rear. Used for one event in Sears Point and they worked great. Looking forward to THill next weekend on them! Fits fine no rub here either.

I have planned a track day for later this month. Lets hope i get to make it.

I've gotten up to 22 heat cycles out of a used set before they corded. So brand new they could probably hit 24/25 sessions - at least for my driving style and the tracks I run. Your mileage may vary.

They start to lose a good bit of grip halfway through those heat cycles (expect 2-2.5 seconds on a 2 minute lap). They are still faster than street tires and decently fun, so I kept running them to see what they would do.
