Last year, I had a local tire store mount my snow tires on a spare set of rims.
They offered to switch the rims onto my car for free (I guess it was already built into the price- most people don't walk in with loose rims, but a nice gesture!!!!

)
They switched them out, and went back with torque wrenches after for final adjustment.
I asked them what they torqued it too.
FWIW- Volvo's- 81ft/lb torque.
Which I remember since I commute on interstate 81 everyday.
Would I let any of them touch the aluminium lug nuts on the p-car? F@#$ no!!!!- Although the indie shop nearby has the right socket...
