quality of used tires down?

My only thought is... Just drive over the tires. That's what we've done when it is necessary. No issues with tires spinning and trailer moving.

Unfortunately, it’s not something I was speculating about. A couple times we backed cars up, and the torque from the wheels would spin the trailer wheels, and we almost got in trouble. Putting a little flat piece on top of them that won’t slide out solved the problem.
