OK, this seems to be going towards 'if you don't overdrive they
won't chunk'

The way I remember it, the original poster was asking
about McKamey.

If you are running decent summer tires, with a lot of tread, then
its a good chance they will chunk at McKamey. Several
of us at the Philly school encountered this.

Of course we overdrove a bit, but our instructors were driving on
them as well. Its my feeling that its the nature of the school. Here
you are running a course that has a few steady state skidpads
where you can easily bake it a bit. But the most important aspect
is that the runs are done *consecutively* without any time to
really cool down the tires. So, you get 8-10 runs back to back,
and full tread tires are begging for mercy. Then you rest/work.
Then you do it again. Chunk city on 8-10/32s of tread!

FWIW, this was a 2600 Integra GS-R on full tread SP8000s.

I now have 1/3 tread front SP-8000s, and near 3/4 tread
rears. The 4-6 run autoXs I have done seem to do little to
chunk them, and they should be super for the ProSolo this
weekend. But to do it again, for McKamey, I probably would
have run beater tires...but that's the price of admission
sometimes for racing :)
