Mounted some new bear claws on my buddy's Rincon factory wheels yesterday. The bead is fine for about 2/3 of the rim, but the last 1/3 won't pop out. I put a LOT of air in them trying to pop the bead on, but got worried I was going to explode the tire.
I think today I'm going to break the bead down on that side and grease everything and try again. How much air pressure is too much when it comes to setting the beads?
