You can't torque the lugnuts "correctly" with grease on the studs as the torque value normally given will be for a dry stud . The torque value will be completely different for a stud with grease as it drastically changes the amount of pressure applied at the same torque . Even different types of grease and oil will require different specs .
Only when a manufacturer provides a special lubricant and a torque value (like with ARP studs) to use with that lube applied should one use grease on studs that have an important job like wheel studs .

That's true, but lug nuts are not heads, manifolds or spark plugs. You're probably not going to strip them out too easily. FWIW I normally torque lugs dry to about 100#. If using anti seize I go to about 90#. I have not broken any studs, nor have my lugs ever worked loose.
