Intro: Taking the Strain Out of Changing a Tire.
The video kind of says it all. The air tank makes it quick and easy, but if you don't have one, a bicycle pump would work, or one of those car tire inflators that plugs into the cigarette lighter.
I came up with this idea after I had a blow out on the trailer you see in the video about midday when the temperature was about 95 degrees. The shoulder of the road was a steep slope and it took me forever sweating bullets to get that wheel on trying to line up lugs bolts that kept spinning around while trying to hold the 60 pound wheel up in place against down hill force. It was murder. It's a wonder I didn't have a heat stroke out there at 71 years old.
My inner tube would have been a life saver in that situation and would have kept the tire held up and stable while i worked with the hole alignment.
