I'm going to do at least a few de's on street tires to get a feel for the car.
I know it's an extremely variable question, but how long do the r compound tires last. Are they generally done after 1 de or can you get a few out of them.

The problem I've encountered, is that even the highest quality performance street tire won't tolerate the heat cycling encountered in continuous lapping DE's. You will get one day of track use AT BEST!. They may still have plenty of tread, but as soon as they get to temp again (as in next track day), WORTHLESS! This is probably much different if you are doing AX. The street tires will likely last much longer.
This was the main reason I first switched to an R-Comp tire - Toyo RA1. I would typically get 8-9 track days with maybe 32-35 heat cycles before they would cord.
The last 2 sets of tires I've run are the BFG R1. Better grip overall, but only 28 heat cycles, PERIOD! The nice thing about the RA1's, you could drive back and forth to the track on them. Not so with the BFG's... Both of the above mentioned tires are likely not the best choice for AX though, IMHO...
