I just pulled up this old thread using Google.

FYI, for anyone looking to do this in 2011:

I just removed my stickers from some 2011 Reynolds Assault Clinchers. Could not have been any easier, almost like they were intended to be peeled off after purchase. I used a bare (and shortly trimmed) fingernail to peel up the end, and then I could remove the entire thing in one pull.

Oh, and the wheels look MUCH nicer. The '11 decals have way too much white.
