With the tire pumped with enough air just to hold it's shape, be sure to stretch the tire on both sides of the valve onto the rim as you go. You can alternate a few inches at a time as you place the tire on to the glued rim. Done properly, the last part of the tire literally falls in place. Done improperly, it can be harder that trying to get a tight clincher onto a tight fitting rim.

Once on, center the tire using the backing tape as a guide. You can even deflate the tire as I have found it easier to pull the tire around on the glued rim with the tire deflated. Just have a small hand pump handy to re inflate to check for true & concentricity.

I would not worry about the glue on the sidewalls. If you take your time, are careful, not much glue hits the sidewalls anyway.

I have used both Acetone & Goof-off with good results for clean up, however be careful with the stuff if you want to keep your decals looking like new.

Seeing as you are using the Zipp Valve extenders, be sure the tire valves are firmly in the open position. You would hate to have them vibrate shut on you.

Have fun.
