Cruiser, lug nuts are never, never lubed for any reason. And don't fall into any crapola from someone who says "My dad lubed his lug nuts for 40 years and it worked for him."
(Yes, I realize that "dad lubed his lug nuts" is an odd phrase)

NO, NEVER!
If they are rusted up, seized on use some penetrating oil to remove them then use some type of solvent to clean the oil off before reinstalling. A wire brush can be used if needed, but NO lubrication or Loctite.

Torque values are expressed for dry threads.
I'm betting you have 1/2" lugs. Take a nut off and go to an auto parts store and have them check what size wheel stud the nut fits.
Then go to Harbor Freight and get a $20 1/2" drive torque wrench with a socket to fit your lug nut. I prefer 6 point sockets. Always back the torque wrench down to zero pounds or less when storing after use.

There's a warning about wheel separation, stating that I need to torque the lug nuts. Problem is, there's a side note about 9/16ths studs receiving a different torque level and I have no idea which studs mount our wheels.

We've searched the manual which is where we found this hiccup.

Can anyone shed some light on this for me?

Wheel nut torque is on page 24.

Hint, lug nut size. In doubt, remove lug nut and measure lug bolt/stud diameter.

You have 1/2" lugs and the torque spec is 120 ft lbs. Don't overthink it. Tighten in increments in a star pattern and do a check after 50 miles.

Nope. Just walked in with the tire iron and found a comparable socket.

3/4" ... not mentioned in the manual but dealership says shoot for 115 ft-lbs.

Didn't need any anti-seize because they're in spec, if that's what you mean. Something about this appears as if you're telling me I need to check my "blinker fluid levels".

Trying not to but our paper manual over "fails" it. ;-)

I'm partial to 614 ~ 773 ~ 677 as a warmup for 691 ~ 620 ... then cruise the BRP aaaaall the way down to 221 ~ BRP again ~ 226 ~ 226A ~ 1100 ~ 1167

... then onto, wait ... this is North Carolina.

Ah, well. "They're back there somewhere" LOLOL

3/4” is the size of the nut, not the stud. The stud is 1/2” if the nut is 3/4”. Bolt heads are usually 1.5 times the diameter of the threaded end and nuts are usually the same, but I have seen nuts that are 1/8” bigger than the bolt heads.

I just read this and started to reply with basically what you said....if the nut is 3/4", the stud is 1/2". You beat me to the draw!

That's good. I usually don't check the blinker fluid, some guys are very anal about it though.

Thought I remember seeing half inch stud torque requirements stating 110 lbs for AL wheels and 120 Lbs for steel. Then again at my age I get excited when I remember where I put my keys a half an hour ago

Should there be a difference on torque requirements for steel or AL wheels ?

Aluminum wheels on our Montana, 1/2" studs, 120 ft lbs on the lug nuts per the manual. No discussion in the manual about steel or aluminum wheels being any different.
