At the risk of being in the minority here, I have used both CounterAct and Innovative balancing beads (CounterAct on BFG 315s and Innovative on Cooper STTs) and they have performed flawlessly... As the tires wear, they often change balancing characteristics (I had my old truck's 285 BFGs balanced 3 or 4 times in their lifespan). The beads, since they are not balanced in a fixed position, move to where they are required to balance out the tire.
After over 25k miles on the BFG 315s, the insides of the tires looked like new - I still have the tires, and will show them to anyone who doesn't believe it...
So - for about $5/tire and a lifetime balance, I am a firm believer in the beads.
NOTE: Neither CounterAct or Innovative have the requirement to use "dried" air as the Equal product (also beads) required. Maybe the newer Equal does not require "dried" air... ?
NOTE 2: I _did_ put in the filtered valve stems to avoid beads causing valve stem leaks - a great investment for less than a $1 each...
