That's the nicest thing about a portable 12v air compressor for airing your tires up after offroading -- an air wrench. This makes changing tires a snap and I used it many times on my old Wrangler. De Vilbis made a nice air wrench that would work with these units 15 years ago, and changing a tire was a snap. I've been trying to find a similar unit online this morning. I think the max torque setting was about 220 ft lbs using a Crafstman 12v portable compressor.
You can never have too many tools!!!
