If you're just going to CHECK the torque, a torque wrench is the correct
tool and an impact wrench is dead wrong.

However, if I had a rig like that with on-board air always available,
I'd darn sure have a good impact wrench just for CHANGING tires! I hate
heaving on a lug wrench and use my impact for all my tire changing needs
in my garage. Also, smaller impact wrenches, butterfly impact wrenches,
air drills, and air grinders are a thousand times more useful than I
ever would have imagined them to be before I got a good compressor years
ago.
