AM Pneumatic Wheel Diameter?

[Kevin Sevcik]

I know, I'm surprised I'm asking this question too. Nevertheless, I need the diameter of a stock AM pneumatic wheel. Preferably inflated to 35psi or so. See, we only had the 6, and they're all in the bag with the robot....

Warning: Anyone who tells me it's 8" and links the AM spec page or CAD file risks being laughed out of the thread. That 8" diameter figure on the spec page is a transparent lie meant to cloud the minds of simple draftmens that think 2x4's really are.

Context: We're looking at swapping in either 6" or 8" IFI or performance wheels to get rid of the hilarious bounciness of our foolish 6-wheel pneumatic drivetrain. (Yes, we tried lowering the pressure in the outside tires and a few other things besides.) We need to know how much extra height we're going to get over the current wheels, as that starts pushing bumpers and things towards limits.
