Do you torque 2-piece lug nuts to different specs than traditional one piece lug nuts?

I know that on commercial trucks there are two types of lug nuts with one being similar to a two piece design and the other a one piece design. You do not tighten the two piece design as tight as the one piece design because of the additional torque generated from the one piece against the rims while the two piece design all of the torque is on stud. Perhaps the Kics are different because friction is generated between the two parts? Not sure. Anyone have an opinion/experience?

I just torque mine to 85 and I havent had any problem with it so far... To me I just feel safer with close to OE spec torque

Thanks! Anyone else run 2-piece lug nuts?

Yeah I'm running kics r40s and have them torqued to 90. I think 80 was recommended. Haven't had a problem with them yet.
