I had a tire liner that worked miracles, but the stiff material became brittle after a few years, cracked, and sliced into my tube. I don't remember if it was "Mr Tuffy" or "Stop Flats" brand, but I replaced it with a "Slime" brand liner to see if that might prevent this problem.
Well today I found out that the softer slime brand liner will not prevent glass from puncturing my tube at all, which is a far worse fate than a liner that just needs to be replaced when the bike is overhauled.
Does anyone have a preference between "Stop Flats 2" and "Mr Tuffy" before I pick up a replacement? I learned my lesson that some brands are much inferior to others and I'd like to get squared away before work tomorrow.
I heard that "Stop Flats 2" is made by the original makers of Mr Tuffy, who sold the "Mr Tuffy" brand name to someone else. Is that true?
