So those irons can break the bead!? Do they work pretty well as a breaker? I think I'll stay with my rim protectors, the ones in the video seem to want to pop off.
One thing about the video, I have found that the valve stem isn't necessarily the heaviest spot on the rim. Now, I check the balance of the wheel without the tire and mark the heavy spot which I have found can be as much as 8 inches away from the valve stem. Doing this check, has made getting perfect balance a lot easier.
