GeoCorp Behemoth Wheel

It can reach the speed of 46 mph.

Usage
These wheels are the really, really powerful ones. Not so much for combat, but in terms of capacity it's unrivaled when compared to most, if not all, wheel and flight blocks. Sure, the Anti-Gravity Engines can carry a lot more, but those wheels can run without electricity. They are slow, clunky, and hard to protect, but in exchange Techs with these wheels will have an easier time navigating hazardous terrain, and are also able to have much more blocks than with other wheels without too much of an impact on the speed, partially solving the Protection issue by adding more batteries and shield bubble projectors.

Overall, these are the best if one demands size and doesn't care much more for the rest of their tech.

Trivia

 * It is the second largest wheel block in the entire game, only losing to the Venture Titan Truck Wheel.
