I have done 5 races on Tufo tape strips now and I am very impressed. I initially installed the standard strips but those are only to good in cool temps. I went back and and changed to extreme strips as I live in Texas. Once you remove a tire with the strip it is essentially now a spare. All of the tape stays on the cotton, which is good ,as now it is sort of pre glued as a spare. I don't think I would leave it on permanently though, as the adhesion is probably not as strong as a new strip would be. The other nice thing is that all the residue comes off the wheel with the tire and my 303's still look new. Also, no more excess glue everywhere. They are also pressure activated so you do not have to wait a day before using them.
