Eventually, the stud will start necking which is the point where the stud no longer can react the clamp load to hold the wheel on. If you lose clamp load on your lug nuts, you're gonna have a bad time.
The safest thing to do is get the grease out of your threads (both stud and lug nut) and go back to 140 ft-lbs. That takes all the guess work out of making sure you aren't damaging your threads over time and that you're applying the right clamp load to hold the wheels on.

honestly I had only recently learned about reducing the torque with anti seize. This last time I had my wheels off I tried to not put any on the studs and I wiped off what I could from before, but I didn't brake clean it off or anything so I'm sure there was still some residual on there. That was my thinking for the 120. I felt comfortable with that number for my purposes, but I'll probably brake clean them next time and go back to 140.
Definitely a good point though. I'll remove the 120 from the original post.
