One of the problems in balancing trailer wheels is that they don't center on the center hole but rather on the lug bolts. All the wheel balancing machines center the wheel on the center hole. If that center hole is off from the bolt pattern by just a small amount you could do more harm than good. IMHO it would be better to use the stuff that most truckers use. It goes inside the tire. There are also devices that go on the lug bolts behind the wheel. I have these on the front wheels of my truck. They are very effective.
