while waiting for my new tubes to arrive i figured i'd mount the new tires with the old tube to see how it go's , i guess i didn't use enough air or the tire wasn't all the way up into the casing cause i pinched it. i going to be supper careful with the new one. i'm getting a weighted plastic mallet to knock the last 6" of bead over the rim instead of prying it. i got the first bead over with just my hands so second one should go with a few taps with the mallet. no more prying i can tell you that!! oh yeah just so you know most baby powder is corn starch. you can get j&j baby powder original formula that's asbestos free real talc that can be used on the tubes.

Instead of talcum powder I have been using powdered graphite when I mount tubed tires. The graphite is slippery, like talc, but it is also electrically conductive. While I don't know whether it makes a difference, I figure it will eliminate one possible source of static electricity. In these modern days of electronic ignition and fuel injection, not to mention the electronics many riders use such as GPS, music players, cell phones and so on, that might just possibly help.

Static electricity is generated when two dissimilar non-conductive materials rub together. When the voltage gets high enough a spark jumps between them to equalize the voltages. Putting a conductive material between them (in this case graphite, although water would also work) allows the charges to equalize before any serious potential builds up. That is why gunpowder usually is coated in graphite, although the reason there is fire or explosion rather than electrical interference. I do not know that there is enough motion between the tire and tube to generate any charge, nor do I know if the material of the tire and tube is dissimilar enough to generate static in the first place. Using talc (or graphite) when installing tubed tires is supposed to allow the tube to sort of "settle itself" into place during the install. I simply think that using a conductive lubricant such as graphite can't hurt, and might conceivably help.
