We bought our Tahoe a month ago this Thurs. It’s a Premier with the 22” wheels. We bought it with 5 miles on the clock and now have a little over 500. I walked out of a store tonight and noticed a lug nut missing from the passenger side rear wheel. I got the truck home and found another 4 on different wheels all loose to different degrees. I’ve bought a lot of new cars and never had an issue like this.
Check Your Lug Nuts!

Oops. Somebody did a swap at the dealership and forgot to tighten the nuts.

We regularly spot check ours, about 100 miles after a tire rotation or removal for any reason. 140 foot pounds. Then again, maybe someone was trying to steal them.

Aren’t all 22” rims installed at the dealerships? They usually come with black steel wheels.
Go back to dealership to get replacement and couple free oil changes

They are. I believe lugs are supposed to be retorqued after a few hundred miles - not that most people do that.
No, not all 22" wheels are installed at the dealer. Yes, it is always a good idea to recheck the torque on the lug nuts but no one does.

140 ft*lb sounds like a lot. I usually do 115 ft*lb on the 18" rims if I remember correctly. Must be a 22" thing. Smaller rim size is better. Extra un-sprung weight is the enemy of power delivery, ride quality and replacement tire cost. With the higher torques, you run the risk of rotor warping.
Ever since I started doing my own rotations decades ago, I have yet to lose a lug nut. Whenever someone else does work on my vehicle, I always do a follow up check. More often than not, I find problems. Trust but verify.
I never retorque aluminum rims as was noted here, and I have never had an issue. All my rims are always aluminum.
Where did you come up with 115 ft/lbs? Specs for our trucks is 140 ft/lbs for all years. If you don’t believe the specs, here’s the values on Alldatadiy for my 02 and 08.
Also, it doesn’t matter if your rims are aluminum or any other material, they should be checked after a few miles but like mentioned nobody does.
^^^^^Agree^^^^^
140 ft-lbs on lug nuts is spec for these rigs. I always find it interesting, as an engineer, how people will discount things like this that are directly related to the vehicles safety and think they are smarter than all the engineers that the auto makers employ given the fact that many folks don't truly understand the science behind torqueing a fastener.

Because people don’t understand how things actually work. They think because GM “makes mistakes” that the engineers are stupid and don’t know anything.

I take my wheels off and on all the time so I only tighten to 100. I use to only tighten to 80 lbs. until I noticed they were starting to get loose.
You’re joking, right?

Totally serious. I don't Tow or Haul or have any kids in the truck and don't drive that many miles. Never had any problems till this summer so I bumped it up to 100. 140 is what is Recommended. I have my own thoughts on this and not only do I check my Lugs often but keep a breaker bar with a 22mm deep socket in my truck at all times.
