So right now our only choice is to increase the psi... and bounce ALOT. So if there is any other way to fix this problem without letting air out of the tires, it would be ideal. If not, I guess... oh well.

But thank you for your advice anyways... it is much appreciated.

We had this same problem last year, with our tire pinching when we turned and the rim actually popping it. The solution for us was to cover one set of tires in the 2" pool hose from home depot. We called this "poor mans omni wheels" It grips fairly well forward and reverse, but can glide sideways. We also tried filling the tires with expanding foam (also from home depot) to deaden the bounciness a bit but this added alot of weight.

The easiest solution is to put zip ties around the wheels. Ugly, but it has a simmilar effect as the pool hose.

I will be at UTC tomorrow, and I hope to see all of the great machines in action!
Best of luck!
