Matthew,
I typically use a small amount of Never-Seize paste on each stud on all my vehicles. You can usually find it at your FLAPS. Not to excess now, just a knick with the brush. You don't need excess under the contact face of the nut. The action of threading the nuts on will distribute the paste to the thread bottoms. Because old/big trucks often don't get their wheels off for years, this will help you at some future time. It is also prudent to torque the wheel nuts to the factory recommended spec. and check the torque from time to time (after a big drive or rough route) to see if they have changed. Caution: Not torquing or low torque = problems like loose nuts or damaged studs. When you take the nuts off, don't set them in dirt or gravel. The paste will attract grit and you will need to rinse them in a can of varsol and blow them clean. Never-Seize (or equiv.) has worked fine for me for over 40 yrs with no ill effects.
Others may differ or offer contrary opinions.
