I took the spare tire out of the Hummer and let it sit in the garage fulltime. In its place I have a small plastic case with handle, a complete tire repair kit! The tire repair kit is useless without ability to reinflate the tire, which I can with the Hummer air system.
I have yet to study the tire repair technics, but I usually work better under pressure. I like to make my decisions with the waiter standing next to me.
