I like to think my dented rims are from too low pressure and too much 
weight/motion rocking the Scout down onto 'em or slamming the tire into a 
rock and then pushing in 'till the rim meets rock..

The dummy that hadn't aired down, and didn't have a PULL-PAL to use his 
expensive winch on his expensive vehicle in the anchor-less sand.  :-)

BTW, saw another ZJ with a winch on it... you're not the ONLY one, John!

I made an adapter like Bill Theberts for airing down 2 tires.. or up.

Just some 3/8" air line, some clip-on air chucks, and a T.

One side has a male quck connect for coupling to my on-board air 50ft 
coil hose's chuck.

One side has a female coupler.. with either a valve-stem thing on it for 
using a pencil gauge.. or put my new 0-60psi air guage on a quick connect 
into it.

I also have an on/off air flow valve.

Filling the tires, I can use this valve to let air from teh compressor 
into the tires.. then turn it "off" so I can check pressure, then back on.

Air down?  Don't hook the 50ft coil up, and use the male quick connect to 
blow air out very rapidly.. and control it (again, check the pressure) 
with that on/off valve.

Now to just get a front bumper w/ air tank fabbed...
