When assembling anything that requires a specific torque value you need to add the "running torque" value to the total. So if you nuts are rusty and as you tighten them the torque wrench reads 25lbs. Then if your required torque number is 450lbs then you would torque it to 475lbs.
Lubricant on the threads only affects the running torque it is the friction on the face of the nut that keeps it in place. That is one of the reasons lug nuts are tapered, more surface area, and it centers the wheel also. BTW the torque for a '52 M135 lug nut is 450lbs.

Jeeeze. I'm sorry to have started this argument. My feeling is that I don't
have enough technical knowlege to figure all this out. For instance, in an
ideal laboratory setting, if you use a torque wrench on a rusty nut, and get
100 foot pounds, and you use the same torque wrench on a lubricated nut, and
tighten it to 100 foot pounds, are you saying that the lubricated one is
"looser" than the rusty one? How can there be difference in that situation,
compared to, say, a rusted nut versus a brand-new, shiny, non-lubricated
nut? Wouldn't the new nut be more prone to come loose, following this line
of reasoning?
