Review on Pneumatic Caster Wheel Swiveling Plate by Sam Simone

As other reviewers have noted, under load (approx 600lbs on 4 rollers) the roller does not spin properly, you have to kick the tire to guide it in the direction you want to rotate. Useful but inconvenient Added 4/10/2017 Today I wanted to roll my cart with these tires, two tires are flat, the other two are low on air. One of the flats has a tear in the middle of the tread, that's toast. Unfortunately I have a nearly full 50 gallon diesel tank and I don't know how to change a tire.
