I have been using my ACME tow dolly for 3 summers now. I am on my 2nd set of tires. Balancing beads on the original tires. Never had any issues with them. I am not sure how to tell if they ever went out of balance though. But my dolly pulled straight, using my previous Class C. (Haven't towed it yet using our new THOR Class A).
Using regular balancing weight from Discount Tires now as I purchased my replacement tires from them. But they do not have balancing beads available. I pulled it about 4K miles with no problem (using regular lead weights).
