Flat tires never come via appointment, nor do crashes.
Hence, keeping a US 1-dollar bill and some gorilla glue "black tape" in my tire repair kit for the purpose of sealing patching those nasty "gash type cuts" holes in a tire, say from rolling over shards of glass or sharp slicing torn aluminum can.
I then repair the tire with the strong paper dollar bill and or black tape by fastening it to/on the "inside" of the tire to prevent new inner tube from blowing out of the same hole again once wheel is assembled and inflated with air.
I keep 12-inch piece of tape stuck around my onboard air pump and unpeel it to use as needed.
A USA Team pro bicycle mechanic "Steve Donovan" taught me this tool trick and I've utilized it twice in my lifetime.
This tool trick keeps you rolling and back home in a pinch.
Old school steel tire levers are my favorite.
Crashing always Sucks!
