Normal
i have run ultra heavy tubes for years but couldnt run anything lower than 10psi with them in fear of a pinch flat. with tubliss i run 7-9 i still can get a flat but its very easy to plug. at the last race i got a slow leak i could feel going down green slim slowed it down ended up doing 2 laps on a flat trials tire witch is very hard to deal with. if it would of been a knobby i probably wouldnt have noticed it as much trails side walls are much weaker when flat than a knobby.anyway the tubliss never failed the next day washed the bike plugged 4 holes in the side wall and was ready to go again. tubliss has saved me hundreds of dollars in tube costs.
