Those reflective wheel strips are hard as hell to do unless you have a bike lift. I wish I had let a shop do mine. I press wrinkles out every now and then on my contrasting red rim tapes (when I see a wrinkle.) Mine was hard since I got a dried up backing material, and it took me forever to peel mine off for about half the pack (an ebay special for full retail.)
If anyone buys them, it would be worth the time to correspond with the vendor first to make sure the backing material paper is not dried up. It adds hours to the job if they are dried up, and seems impossible at first to make sure you cover your wheels by peeling all of them off.
It changed my tune from a happy buyer to a pissed off buyer, and I had several wrinkles partly due to them by hurrying up (I wasn't planning to spend half a work-week on peeling dried up stickers off the backing paper.)
