I break them free and then use my LITTLE Ryobi 3/8" drill. It would easily
do 6 tire changes including the decorative caps that cover the lug nuts.
All for less than $100 and it is light enough that I use it for most things
around the house instead of my 1/2" corded drill.
I use a torque wrench to do the final tightening after I have spun the nuts
back on with the drill.
