I used to dock my racecar on a set of the harbor freight to move around in my 2 car garage. It would always take two people to shift it around effectively. You need to overcome the binding of the casters, the steel ones I had on my set would even on smooth concrete bind doing it solo. Two people no problem, but doing it myself I would turn the caster with a pipe wrench when it jammed.

I could not imagine sticky rubber casters.....
