I don't use any. The old fashioned method of balancing with weights has always worked for me just like it has for millions of others. If the balance beads were so good why don't they use that method on new cars and trucks? It's certainly less labor intensive. All you need to do is remove the vale core, pour them in, replace the valve core and re=inflate the tire. Doesn't sound like you need to know much more than that to try them...I would never allow any sealant gunk inside my tires if that's what they want to use. Ask any tire shop about how it makes it impossible to repair a flat...
