Ninja-Edit: GM permission to give you guys my wheels vs treads rundown.
I'd vote for Pyro as leader, because I can influence his decisions with my psy- he is a good, level-headed man and worthy of our admiration and respect. Ahem.
Wheels vs treads/tracks. Wheels are made for smooth-traction surfaces like asphalt that provide enough friction to stabilize during and after acceleration while allowing enough inertial potential for the vehicle not to stall nor veer out of control. Not too little, not too much. Perfection. The problem while standard wheels, as anyone who's driven in snow, sleet, sand or mud can attest, is that grainy particles, inconsistent terrain or moisture tends to either grind wheels to a halt due to excessive friction or cause wheels to spin wildly out of control due to not enough friction. Either situation is very bad in a gun-fight with high-explosives where you do NOT want to lose control of the habitat nor have it randomly stop in the middle of your enemy's gunsights.
Treads/tracks on the other hand are more suitable for larger vehicles, such as our very own monumental habitat vehicle; easily outclassing any 21st century war tank in sheer size and weight. For one to move such a significant mass across any feasible distance over undoubtedly rough post-apocalyptic terrain no one has handled in decades or centuries, one much utilize a system of movement that is consistent with the harsh conditions faced by the very vehicle being utilized.
Now, do you honestly believe a wheel 1/30th or so the size of a massive hulking pile of steel will allow you to safely, quickly, and effectively move over dirt, sand, stone, pebbles, rain, snow, mud, and gods know what else we're encountering in our world? Do you honestly think you can design an effective basic axle-and-wheel system robust enough to support the indecipherable amount of weight our habitat possesses? Just think if each Pixel is man-sized, just how utterly massive the habitat must be...
I do believe our best choice here, if we are to remain within the realm of sanity or have any chance of travel mobility, will be to design a proper tank track system, like those used in...
PANZER ATTAAAAAAAAAAAAACK
...Ahem... Sorry about that.
Anyway, we must utilize a proper tank-like track system that will COMBINE the speed and utility of the common wheel with the terrain stability advantage of treads in order to outmaneuver and outclass our enemies. We simply cannot expect to feasibly counter an enemy threat when even a medium-sized stone could damage our vehicle's wheels beyond use. Tank treads? Roll right over the biggest stones, through a ditch, over glass, metal scraps and sand. Everything.
I think you all know who the clear victor in this debate is.
TANK TRACKS FOR 2314.
