Collapsible 14" tires were seemingly not made since the '80s. I called or e-mailed every tire mfgr I could find and got zero replies. Called the big tire resellers & most did not know what I was talking about. Not listed on any website. Tire Rack tech line referred me to Vredelstein- who are in Europe and do not sell to the public. Giant help there.
The wheel is a steel 14"x7" stock Ford wheel-millions in any U.S. wrecking yard. Needs two decals that Hall sells. Some show an over-pressure valve as well as a rubber tire valve- which I do NOT recommend (if you expect to actually use the thing in an emergency).
The inflater can: NA. Be careful of substitutes from Autozone etc- some use PROPANE as a propellant. If the label says DANGER- EXTREMELY FLAMMABLE, you are holding a bomb! At least one 'cooked off' in a rear trunk. Shrapnel dented the trunk lid & broke the latch and tub.
If no one on the List has the assembly, again- a wrecking yard specializing in '70s oldies may be your best bet for tire & inflater can, as well as wheel. Note- there were two versions of the tire; first (BFG) was recalled for sidewall cracking in unused examples within the warranty date.
