i read a bunch of posts about how to do it and they kept mentioning rim lock.. found that out what it was after about 3 hours of the tire not being seated proper.
If the rim lock was tightened down I would have thought you would never have gotten the old tire off!
The biggest issue I have with the rim lock is to make sure that it doesn't pinch the tube. Here is how I put a tire on:
I start by putting the wheel inside the tire. There is a bit of a trick about squashing the tire just right to make the beads open wide and then you can slide the wheel into the tire and with a little pushing it can just slide right in. Now you have the wheel inside the tire, both beads outside the rim.
Now put one bead inside the rim. On the front I will put the rotor side on first and on the rear I will put the sprocket side on first. This is because the other side is less of knuckle buster which will be appreciated when the harder bead is slipped over the rim
With one bead still out I will slip the tube in. I will but just enough air into the tube so that it doesn't want to lie flat. Work the valve stem in first, then poke the tube the rest of the way around, making sure it doesn't have any twists in it. Many of the tubes have some sort of line running around the tube and you can use this to make sure there is no twist.
Now give the rim lock a push up. It will be a little springy because you are pushing against the tube. Make sure that the rim lock moves fairly easily and that it is inside the tire, not trapped against the rim by the bead.
I generally start mounting the final bead just a little ways away from the rim lock. You do NOT want to be completing forcing the bead over the rim next to the rim lock, that is for sure!
Once you have the second bead on give the rim lock a push again. It should move freely.
Inflate the tire, seat the bead, and then tighten down the rim lock.
