The new R6s seem to outlast any previous iteration of Hoosier. My most recent set served well for 6 hard track days and at least one good overheat. They started falling off after about 20 minutes of hard running toward the end, but there is rubber left.
Wow, that's one heck of a tire! How many and how long were each session per track day? How many miles is your track?

20-30 minutes each session, 4-5 sessions days 1-4 and 7 sessions days 5-6. Not easy ones, either, but the tracks (Watkins Glen 3.4mi and Mont Tremblant 2.65mi) are not really hard on tires.

They went away when I overheated them on day 5 and I was going to change to new ones, but a friend convinced me to see how far I could take them. They came back after some cool-off time.

Why the half life? Heat, driving style, track?

That's what happened to me when I cooked them, but they came back after I let them cool down. I wouldn't want to qualify or race on tires in that shape, but they were certainly useable.

Hard to guess but in addition to those, there are track surface, amount of braking, amount of UV the tires have seen and many other variables.

all my research says under 15 HC. my personal experiene on a track that is VERY harsh on tyres was 12 - 15 HC.

ill wait longer with the next ones and see of they last longer.

Poll missed the Pirelli Corsa System which came as OEM fitment on my car. Way better than the Michelin PS2 I had on my Turbo, progressive, can stand heat, progressive at the limit, very even wear, usable in the wet, could not ask for more for a street oriented track tire.

If you have a trailer or a friend with a trailer:

Slicks:

- Michelin: For top times. An overkill if you are not racing, or running a Time Trial where your class allows them. I ran a set on my GT3 for two events, and they were sick. Highest grip I have experienced with any car.

- Good Year slicks (250 compound): Very expensive and not as good as the Michelin S7.

- Yokohama: I bought two sets used. Decent grip, but I think they were shot.

- Pirelli. Never ran them. They make sizes for the GT3. The Cup cars guys buy these instead of the Michelin for longer life.

DOT-R:

- Kumho V710: Probably my favorite tire for fast track times, without killing your budget. They have as much grip as the R6 (if not more). Indeed, in some cases they are as fast as the A6. They last forever.

- Hoosier A6: They are the fastest for auto-X. And they are as fast as slicks for two laps at the track. For time trials, this is what I use.

- Hoosier R6: Consistent, lots of grip, they don't last as long as other DOT-R. Your choice for fast times are these or the V710.

- BFG-R1: No experience.


No trailer:

Toyo RA-1. I put 8,000 miles on one set. Good on the street/track/auto-x. Faster as they wear out. Slow when new. No shaving. This tire will be history once the R888 replaces it. Spec Tire on several Racing series, so lots of development goes on them.

I have driven to some events on the A6, V710. I put 1,000 street miles on a set of V710, and around 500 street miles on A6.

Disclaimer: If you get pulled over on the streets by a traffic cop, while driving on any DOT-R tire like Hoosier R6/A6, V710, R1, most likely they will tow your car, as soon as they read "Not Intended for Highway Use" on your tires.
