A 6 wheel drive train with a standard drop won't turn well when the tires are compressible so that all 6 are on the ground.

Would increasing the pressure in the center tire, while lowering the pressure in the outer wheels have a positive effect?

Under high speed they wobble badly (can be balanced) and expand.

We found a very counter-intuitive fix to this. Basically, take a little strip of metal (~2 inches long) and attach it at one end to one of the bolt holes in the wheel. It's a bit of a feelings game, but when you adjust the strip of metal the right way, you can eliminate a lot of the vibration.
