what is the sidewall rating on your tires? Sounds like the steel bands may be slipping. I've had that happen to me before, and the extreme end result is a weak spot in the sidewall that'll cause some shimmy in the short run and a blow out in the long run.

When you say bubbles, is that round bubbles, or enlongated ones?
