If the compressor motor kicks in, quit using the impact until the compressor fills the tank and shuts off. I use an IR 231 on a compressor with a smaller tank and about the same air production; I have to wait but can get the job done for anything I've encountered.

If you remove the center cap, you can access the axle nut through the center of the wheel. With the wheel on the ground, the e-brake set, and maybe the wheels chocked, you get a solid platform to work with if you put the jack handle on the breaker. But be careful: you don't want to be injured if the breaker snaps.

My brother and I have one, we referred to it as "the Super torquer" which was basically a 4 foot long piece of scrap steel tubing. Slide it over the ratchet and hope that either the bolt comes off, the bolt breaks, or the ratchet breaks. Usually the bolt comes off... (or in this case, nut)
