I've never had the need for a mobile impact wrench for wheels (and I
race cars, meaning I'm swapping the tires around on the race car
several times a day.)

I have tried the cordless impact wrenches, and to get a decent one
(i.e. one with enough capacity to handle the really tough jobs,)
you're going to need a name-brand one with a lot of power (18.8v, if
possible.)  These are not cheap.

I'd rather get a 110v one, myself.  DeWalt and Sears Craftsman are
both good ones, but they are HEAVY.
