Does having more duct tape allow you to travel farther from home?
I've used duct tape to boot the inside with success also, actually had the bulge before leaving on a tour, then "repaired it" after it blew out. Haven't seen it used on the outside of the tire until this thread. Whatever works is a good motto.
I agree with the others......... ride it on the rear (with some sort of boot) until you can afford a new skin.
