What is a good compressor tank pressure to mount tires using an impact wrench?

 

Depends on what vehicle you are putting tires on. My truck is 148 psi so I turn the regulator up to about 130-140 for the impact wrench. I always use a torque wrench to set final torque. Car is 100 psi so I set regulator to about 90.

 

You mean Ft. Lbs.?

 

Yes. Been a long day

 

Most air guns are set to run at 90psi. The amount of power they have depends on the brand and size of impact gun.

You also need a big enough air compressor, with enough cfm to properly use the air tool . You can turn the psi up, but it will be harder on the impacts internal parts.

My 1/2 impact will snap bolts within a few seconds. I just snug them up real fast then torque them to proper specs.

 

I never tighten bolts with an impact gun. I may run lug nuts up to the wheel with it, but use a torque wrench for tightening. Some tire shops use "torque sticks" on their impacts, but I have found that they overtighten by a lot.

 

(smallish) Portable 20 gal. compressor Reg. set @ 110 psi, not enough CFM to run the 1/2" composite Impact gun here at 90.

Impact gun is always oiled with a few drops of air tool oil, before use.

Gun is handy to quickly loosen / remove a wheel.

Almost never use to install or tighten a wheel: I start all fasteners by hand, and run up with a breaker bar - I want to know (feel by hand) if there are any issues with a wheel stud, or lug nut on the vehicle. Seems like over-kill: but this is DIY - I got the time.

A proper 1/2" Torque wrench is used to set final torque value here also.

* Same as everyone above.

 

Was in Homey D yesterday, picking up a replacement snow broom handle & buckets for sand,
front store area was loaded with tool chests and (Dewalt, etc.) cordless tools. I was tempted..

 

I bought a Ridgid 18 volt impact last summer to use getting the heavy bolts loose on my deck repair job.
As you mentioned, the hoses and such are always under foot.

Some electric impacts will do OK, but air can't be beat for doing the heavy lifting.

I have a 12 cu ft compressor on a 12 gallon portable roll around unit, and it will run the small tools great (1/4, 3/8, 1/2 impacts plus the 1/4 die grinder and other stuff fine.

My big 1 inch impact (Used on the big rig) would usually get 5 of the 10 lugs off before I had to wait for it to pump up fully again.

A good 12 cu ft compressor on a 12 to 20 gallon tank with wheels (240 volt) is fine for the home shop unless you are running big air tools that hog a bunch of air.

Back in the day I bought the tank with wheels and handle, then scrounged up the compressor, motor and control switch, then bolted it together.

That was 1985 and its still going strong..



The 18 volt was fine for the deck job as I would run out of steam before the battery went dead
