Well tonight I got myself a new D756 and I mounted it to the front rim. So far pretty uneventful, however it's not on evenly. i.e. if you follow the little line around the edge of the bead, in some places it sticks out away from the rim and in other places it's almost even with the rim. I sprayed the bead good with windex and then put about 40# of air in it to try to get it to slide itself into place and it's mostly straitened out but it's not perfect. Is there a trick to this? I haven't tightened the rim lock yet so I'm sure that it's not because the rim lock is holding it down. Thanks!
