I'm not saying pneumatic wheels are bad, I'm just saying make sure you really want them, and all the inherent problems that may come with them.
You mean the problems that become apparent (such as turning) when you use tracks and your robot is longer than it is wide (IE the tracks are on the long side of the robot vs. the shorter side)? If so, we think we will be all set by using a 6 wheel drive and lowering the center wheel by half an inch or so (not a final number).
