Greasy nuts

For years, on all the cars I have owned I have lightly greased the wheel nuts or studs
When I was younger and dabbling in car mechanics my friends did too.

I never had any problems, and I don't recall my friends having any either

But I've heard a couple of comments recently that nuts should not be greased, though I can't remember the reason.

So, please, to grease or not to grease, or any other comments.
And is there any difference between steel or alloy nuts?

Re: Greasy nuts

I have never heard that you shouldn't grease nuts although I have heard that WD4o shouldn't be used as it dries out eventually. My ex Father in law always insisted on slapping old engine oil everywhere under the car after an oil change.

Put it this way, if wheel nuts should be grease that is how they would have come out of the factory on the cars.
Steel rusts- alloy doesn't

Re: Greasy nuts

The torque settings for wheel nuts are usually specified as a dry setting, ie no lubricant on any of the threads as grease would allow the nuts to be slightly overtightened past the torque settings, thus stretching the wheel bolts

Right, I've done some Surfing and I've been getting contradicting answers - a comment on one forum was "Oh no, not that can of worms again"

These are some of the things I've seen

You should not grease the threads, for the reason stated by Primus1

The reason for greasing threads is in case they become corroded on or rusty, and difficult to remove but in fact the main reason for wheel nuts being too tight is that they have been put on with an air spanner

Unless you're rescuing an old classic that's been left in a field for 40 years wheel nuts are unlikely to be too rusty

Some people have been greasing their threads for years, on many cars, and have never had any problems

Most people do not use a torque wrench to fit wheel nuts, they just do them hand tight. In that case it doesn't make much difference whether you grease or not as long as you don't use excessive force by standing on the wheel brace or using an extension sleeve.

For years all my cars had steel nuts, and I greased them, but my current car is a Fiesta with alloy nuts
I am the second owner, and the first had always had the car serviced by a Ford dealer.
The wheel nuts were ungreased, and I think I'll leave them like that, and see how I go on
