A friend of mine emailed me this. Is this typical?

Coochas

Yes.

In fact, I run GY 255 which can last 1/2 - 1 day including a flip on the rims!

My slicks give me their best for about 60 miles... Thirty laps at Summit Main this past weekend.

I did 3.5 hours of open tracking today at WGI and 2 of my 4 brand-new-to-this-event RE71Rs will need to be flipped on the rims for Mid-O next week.

Typical for street tires at a HPDE? Not anywhere close. It has been a long time since I ran street tires, but my NT01s last for 60 or so heat cycles until they cord. So far my current set have been through 55 HC and have probably 40 or 35% tread left! Lighter car (2800 lbs and 245 hp) so YMMV but that is 5 weekends so far and still sticky.

The best band for the buck, Nitto NT-01 tires, bar none. Expect 20+ heat cycles. The down side, they are rated at DOT 100, contrast to Hoosiers DOT 40, harder ribber = slower track times (2 seconds a lap?). If you are out there just for fun, the NT-01 is a spectacular tire.

I just cooked a rear R7 Hoosier last weekend, 11 heat cycles...right down to the cord. I was running them at Willow Springs Raceway, 90 + degrees. I was anticipating using them for practice tires through about HC 15, not the case. The fronts felt good....may just buy 2 new rears and replace the fronts as needed. Not "classic" tire management strategy, agreed.

I don't think you'll cord/heat cycle Pzero slicks in one weekend unless you're doing a LOT of sessions or driving poorly.

ProCoach

Folks, it's super dependent on speed... one person's nine-tenths (twenty heat cycles) is another person's seven-tenths (four to six heat cycles at their nine-tenths).

tire brand & model, speed, track, setup, car, drive style/smoothness, weather all come into play

this is a pic of my new RE71R after 8 heat cycles on WGI resulting in about 6 hours of actual run time on my GT4 during relatively cool (45-65F) weather
I was running 2:09 - 2:11

And track. Some tracks are much more abrasive on tires than others. It's going to be pretty vehicle/driver specific.

ProCoach

Yes, Roebling or CMP could destroy a set of tires in one session, if you're not careful... Same with the left front at Mid-Ohio.

The Glen or VIR? Not so much.

gbuff

Agree re Mid-O....also, I can just FEEL my left front grinding away through T3, and especially T5 @ Mosport

And also agree about WGI--with stock suspension settings I still get wear but nothing like it was prior to the repave

The 2 fronts? Trying to steer, brake AND power-down with those two, aren't you!

gbuff

You got it, m' friend FWD is a blessing and a curse--upside, car was great in the brief rain @ WGI.....

And the left rear ain't so great either, but it'll fly for a day with Chin @ Mid-O....right rear not bad, as I was told by two drivers behind me that it's off the ground going through the Glen's outer loop

ProCoach

You are the MAN!
