The only possibility that I have heard is perhaps Mars is where life started, got blasted off by an asteroid impact, fragments came to earth and restarted here as Mars became inhospitable. That was decades ago and we have done lots of studies on Mars since, so the plausibility of that I don’t really know.

We have put millions of kms on our vehicles. We know about them loosening, however, there will always be people saying it is nonsense or an error in the initial torque. Follow your pattern, set the proper torque, every once in a while some will loosen on their own. That’s why we have pre trip inspections and a ton of regulations on our vehicles.

And if you over tighten then you are weakening the studs and can ruin your threads. Ounce of prevention as they say.

It has nothing to do with the torque value and everything to do with the material. I have had dozens of vehicles, driven hundreds. Aluminum rims often come loose. The nature of the material. I have torque wrenches and a big shop.

On one set of rims it takes about 15 minutes to torque each wheel the first time then a short drive and some of the nuts loosen. 2015 f350. The Ford diesel mechanic noted the same thing and he hates those rims too.

I was at a garage where the mechanic told the customers that retorquing was bull and he had never done it once in his life. He was a fool.

Wheels come off less often now then 30 years ago, after which they introduced retorquing tires.
