This study, it should be noted, was performed on a series of 10 vermincycles aka “rodent wheels” constructed out of passivated high-strength aircraft aluminum alloy machined to tolerances of +/- .0001 mm at a cost of $837,300.

So? Custom-built research equipment is never cheap and if you want accurate data, your equipment needs materials with appropriate properties and low tolerances.

In that case, I’ll be sure to check my tire inflation carefully, and to do that, I think I’ll need a $439,500. combination pressure gauge and interferometer, plus I will need to check the isotopis proportions of each of the nitrogen, oxygen, and argon contained within my tires, because those factors affect the angular velocity of the gases acting on the inside walls of the tires, as well as the balance of the cetifugal and centripedal forces acting on my 20” rims.
