I have some questions about this as well. Drag racers usually have lower pressure in the drive wheels to promote grip, but in a corner lower pressure will allow the tire to roll over a lot more on to the sidewall. I believe that this is when they will break away, but I'm guessing you will also be wearing the tires down on the sidewalls... where they are not designed to be driven on.

I am more inclined to try the high pressure approach for the rear tires. testing and recording the results is really the only way to know for sure.
