Yeah, I finally figured this out.

My problem was I started with the "Semi Solid Forged" stickers, which I stuck on the rim's lip. I figured I'd stsart w/ the ones I didn't car about. Anyway, when I stuck them on, the backing pulled them right back up again, so I stuck them back down (not pulling the backing back up), and figured they were decals. By the time I got around to looking up decal application on the net, and went to go pull them off and try the warm water technique, they stuck.

Apparently the many letters with small area don't grab very well and you just have to be a little patient when pulling the backing off so you don't pull the letters up too. The "SSR" and "Competition" ones are a lot easier.
