Lug nuts shouldn’t be tigtened much past 100-120ftlbs so it shouldn’t take much more than that to get them off(unless they’re corroded). I would be really surprised if any impact wrench couldn’t do it unless you have a fleet of mac trucks. Before you go buy tools make sure your compressor is rated high enough. If you can’t get 8-10cfm at 90psi than you may need a new compressor. As for cheap tools, they work fine as long as you don’t expect them to go all day every day. Keep them lubed with dry air and they’ll usually last for years. Harbor freight often has them for 20 bucks. You could buy four of them for the same cost as one at Home Depot(and sometimes they’re the same).

well anyone above 200 lbs of torque would be fine. i got the earthquake 1/2inch impact and i work on cars every day and it works like a champ it cost about 80.00 bucks i hope this helps

IR makes great air tools. A cheap impact gun is not worth buying. I own 2 snap on 1/2 inch impacts and they suck. My Mac tools is way better and my graphite IR is the best. A graphite IR 3/8 impact will change a tire.

hi- i use impact guns every day-our compressors put out a constant 105 lbs – that should do the trick(its also enough pressure to break city streets with a jack hammer

you should have 200 to be safe most wheels are around 100.

harbor freight tools are junk. the best impact wrench for the money believe it or not is the stanley from walmart. I think only the super centers sell it. it’s about 90.00 and I have yet to have a problem breaking loose a lug nut with it and i do this daily. I am unsure of it’s torque rating, but it’s pretty good.
lug nuts are usually torqued at 100 ft lbs, that’s when the installer actually torques them rather than just putting the impact wrench to them. they do require more than that to break them loose though.

Your vehicle's owners manual will give you the exact details on how much torque the lugs need. Generally, between 130-170 ft. lbs.
