WHEN my truck goes to dealer for say oil change/tire rotation I have spoken to my SA, also. I NEVA allow them to run the tires on with an air gun. They can snug them, but I stand there and WATCH them use a Torque Wrench set at 130 lbs. I also carry a torque wrench with 22 MM socket too. One time, I saw a "kid" doing something I would not appreciate and he never got to do his stupidity, as I stopped him and had SA come out and fix issue. Just how I am ref truck. AND heck no, running a 6 lug truck with just 4 lugs, well,, maybe real short local run to go to shop and replace before trip. AND as suggested, U may want to check all the lugs and see if the "kid" ran any more on sideways, etc, just saying. ALSO, make sure they replace the lugs too, U gotta watch em, just saying. But, also, your truck and yer Bizness, OP do as U feel OK with.
