Over inflate your middle wheels and under inflate your outer ones. This alone won't be enough though, and you may need to wrap your outer wheels in tape - something slippery.

Something interesting we noted:

With no load(weight) on the tires decreasing the air pressure can actually increase the diameter. It seems that as we add air pressure, the side walls of the tire bulge out more decreasing the diameter.

Re: Power draw issues

We had the same problem, and fixed it by adding some gorilla tape covering our rear wheels (it's very back heavy). We tried a few kinds of tape, and that worked the best.

Re: Power draw issues

We had the same situation and the same problem (two toughboxes, 4 CIMS) and fixed it by resembling the tough boxes with a higher gear ratio. Instead of using the originals that came with it, we went up to the 12.75:1 ratio and that fixed it.

The real problem with computers is that they do what you tell them to do, not what you want them to do.
