I added Mr Tuffy to my Continental GP4000 II tires after getting two punctures in a month 2 years ago on these tires (had the tires for less than two months!). Didn't get a puncture since then. From what I read online, it only add a few watt of resistance to the ride. Some say the edge of the Mr Tuffy will wear the tubes and cause flats. Since I replace my Conti for Schwalbe when it gets colder (just in case I do get a puncture, replacing a tire when it's cold is much worse than during fair weather), the Mr Tuffy is never at the same place so this problem is moot.
