Don't run the drag radials on an autocross course. Drag radials, by design, have a weaker sidewall to allow for flex during hard launches. Autocrossing requires very stiff sidewalls to keep the tire from "rolling over". So, although the drag radials might not "peel" off, you will damage their sidewalls using them for auto-x.

In terms of 20" autocross tires, see my sig for what I'm running. Your best bet is to run as wide a tire as possible front and rear. I'm looking into running 10.5" or even 11" rims up front for my car.

R-compound tires are hard to come by in 20". In fact, I think only the Toyo R888s are 20" R-compound.
