Also for wheelers- make sure your tires aren't spinning on the rim when you're aired down.

I used a die-grinder with a cutoff wheel to mark the inside sidewall of my rims and tires so that I can tell when they've spun. When they do, I take the tire off, let the air out, break the beads w/ the hi-lift, spin the rim back to where it was, air back up and I'm good to go again. Since doing this, I don't have to rebalance very often. smile
