In particular, is there a break in difference between slicks and 200tw “drive em to the track” tires?

If they’re 200tw tires, driving it to the track won’t do it. I’m not sure if it’s a heat cycle they need, or a good scrub, or a combination of the two, but in my experience both the RE71 and Rivals were noticeably better on their second autocross event.

Hoosier recommends for the SM7s that the tires be brought up to temp and then put away for 24 hours for best results.  If you go to the tire company's website you should be able to get their procedure.

I like the 200TW class and I have tried several different brands.  The CW is they don't need a heat cycle/24 cool-off like the 100TW and lower tires do.  But that heat cycle practice is for durability purposes.  I always heat cycle 100TWs on down, even though it's a PITA.

Many 200TW don't seem to need any special babying and I have used many sets of Nitto NT01s down to the cords with good grip throughout.  Also, over the winter I put mine in trash bags (still mounted) and store them in a garage that usually hovers in the low 50s.  I've had some be fine for three seasons (two winters) before I corded them.

Check around on the racing forums, like Bimmerforums, to see what people say about whatever brand you're running.  Lots of good experience there.

They will last longer if you get them up to temp (5 or so track laps) and then let them cool back to ambient temp.

 

Not necessary for autocross, but pretty important for champcar, lemons, etc...

In dirt track racing it is normal to put stickers on and go race.

Nascars put stickers on and go race.   Might be some special prep or compound

Reviving this for the current crop of tires. For autocross is this the same? No prep? 
 

my thoughts were I install my re71's, go find a backroad and get used to them, and, in the process, get the slick side worn off. 
 

thoughts?
