Is it necessary/good/bad to put anti-seize paste on wheel lug threads before torquing?
I have never really watched the techs doing my tire rotations until recently, and the kid put some pink paste on the bolts...he told me it is good news from the perspective of not breaking a wheel stud next time, but can this lead to unwanted loosening at high speed?
It shouldn't be a problem if it's torqued to specs. A little lube on the threads will actually be tighter than the effects of friction on an unlubed stud and nut at the same torque specs.
I agree, never-seize almost every bolt or nut you take out or put back in. Saves so much of a headache later in life....not only for you but for the next guy down the line. Especially years from now when someones parting something out or replacing something....helps junk yard rats like myself save the agrevation of breaking something. My father worked for Mack Truck and for CAT way back in the day, if you didnt use anti-seize and someone found out, youd get fired.

Use it! It allows you to get full torque on the nut. Plus it allows you to remove it later. This is a good segue to talk about using a torque wrench on the lug nuts. Worth doing at all times. Run 'em down lightly with the impact to seat the wheel, drop the car and torque the nuts to spec.
It's a good idea especially if you have steel lug nuts against an alloy wheel, to prevent 'galling' the lug nut seat. A dab on the threads will help achieve the correct torque, and, as mentioned, always use a torque wrench. Brian
If you use anti-seize on your lug bolts, then it is wise to check the torque on the lug nuts at certain intervals to make sure that the lug nuts are not slowly backing off. Whenever I rotate my tires on my truck, I use anti-seize on the back of my rims to prevent the aluminum rims from fusing to the steel rotors as this happened to my 2000 F-150 (galvanic reaction).

Just to clear, anti-sieze does not cause nuts to back off. If they do, they were not properly torqued in the first place. Torquing bolts is all about putting the bolt under tension (stretching it a little). That's what keeps it tight.

True but throw in vibration and nuts can work loose even our tractor wheel bolts need to be rechecked ever 50 hrs and they are torqued to 600lbs. Plus I have pto equipment if we don;t use lock tight they vibrate loose even with locknuts. I have used never sieze on lug nuts but found a good cleaning of the stud threads with a wire brush works just as good. Just a different view of the extreme cases.

since i farm 4000 acres i hear ya there about nuts and bolts backing off
I have used a Moly based grease on my lug nuts on several vehicles. It prevents the threads from galling. I'm sure antisieze would do as well but it seems to get on everything else.
I just rotated the tires on my Jeep, quiet down i have 2 Fords too. I bent an 18" lug wrench getting the lugs off after a tire shop guy apparently fell asleep while banging on them with his air wrench. One foot on the bottom, and pulling for all I was worth til each one would CRACK and them come loose. I thought about trying some anti sieze but wasnt sure if it was a good idea. Next time I will. Also had to kick one tire several times to bust it off, prob the alloy rim fusing to the steel.
