A smear on face of the bolt that is in contact with the wheel is all I'd do, and keep the thread dry. Never had an issue with them seizing

You should never put any sort of lubricant on the studs. They rely on the friction to keep them tight.

My mechanic always brushes on a bit of oil to the wheel bolts.

I've never had one seize/stick on me before either. I've had these wheels off a few times in the last year and never had an issue.
Didn't get a chance to go down last night either, tried giving the tyre place a call there but it rang out. I'll try again after lunch.

The problem with lubricating threads arises when you apply a non-lubricated torque to lubricated threads.
The nuts/bolts aren't suddenly going to fly off if you lubricate the threads - in fact, if you put 100 lb/ft into a lubricated thread vs a non lubed thread (depending on lubricant) you could end up with the same axial load as if you had torqued the dry thread to 140/170 lb/ft - this is because less torque is required to put the same load on.
The main thing with wheel nuts/studs is ensuring the threads are clean and free from any rust/dirt etc.

torque is easier reached with lubrication.
"" torque is NOT always tight. ""
show me where there is facts on this, because iv been taught the opposite in my 30 yrs on spanners.
there are some exceptions like stretch head bolts that are still recommended the tinyest dot of a grease can be added to, but i know majority are clean and dry.
i remember wax paper used to be fitted to hubs to stop alloys siezing to hubs.

First link on Google but there's many more.
www.engineeringtoolbox.com/amp/torque-lubrication-effects-d_1693.html
That article mentions roughly 40% reduction in torque required to meet the same axial load on a lubricated fixing vs a dry one. In layman's terms if your manual says 100lbft dry and you set the ratchet at 100 and lube the threads you could end up putting 140lbft+ through the bolt.
We would be told to get the grease off the bolts at tech or to allow for the lubrication.
Whether it matters or not in the real world for a wheel bolt that could probably withstand many times it's rated torque is another matter, but on smaller stuff it can be the difference between tight and rung lol

Liberation from the Impact of Lubricants on Torque Readings
just found the quote my manager said to me as an apprentice in 1984
quote from page"torque isn’t the true measure of bolt tightness—it’s tension"

Some of the bolts in work have to be checked with a gauge for run down torque, then set your torque wrench to compensate for it.

Some of the posts in this thread hurt my brain.
Remember way back when it used to be about some guy that couldn’t undo his wheel nuts or something? lol

Haven't been back down to the car, Sabs is away for the week and doesn't need the car until Monday and I've had a lot on.
Tyre place said as it's been 4 weeks since she bought the tyres they can't be sure they were the last ones to tighten them up, he said they don't use a rattle gun to refit wheels and as I wasn't there when they were getting fitted, I couldn't argue. I've a feeling they may have been a little more lenient if I got the mrs to phone. I don't want to 'name and shame' as I can see where they're coming from tbh.
