Pneumatic wheel drop distance?

There is also no issue with the robot rocking violently back and forth. You can always deflate the center or outer tires to effectively change the drop distance if you are not happy with 1/4".

Are the wheels under the full weight of a competition robot? From what we've seen, as soon as you begin putting weight on the chassis, the wheels compress and you begin to run into the issue of scrubbing again.
