Fix-a-Flat in the pump gallons is a cheap, easy, way to fix annoying bead leaks. If you mount your own tires, tire grease (not really sure if it is just regular grease, it smells like it) on the bead and the rim, prevent bead leaks on steel and aluminum. It makes mounting and dismounting a bunch easier too. Changing tire manually is a real pisser till you learn the tricks, then not so bad. If someone could show you, much faster to learn. Good thing to know, even if you don't plan on doing many. Lots of times nowhere is open, you gotta drop it off and go back, or wait till they get to it. I learned by necessity.
