Re: Bicycle question..
I think a flat is just about the worst possible scenario to be in (can't even pedal home). If I were in doubt about the tubes I would definately replace the one in question (or both) while I had it off the bike. I use the "Extra-Thick Slime Tubes" (10.00 at Wally World) on the stretch cruiser. 500+ miles so far.
