Those rust trails are caused by loose nuts. Boss man saw you leaving the yard like that. He/She'd make you turn around to tire shop and have em tightened down. And cleaned up. They'll also get you pulled in to a scale for inspection.
Wow I didn't know you didn't know what corrosion is. Oil on the studs? if the issue is the torque, the number threads don't matter,
I understand you being sarcastic in the cb forum, being a Ham that makes sense. However, starting off with sarcasm quoting my post and telling me its oxidation first, then corrosion second isn't necessary. To torque those lugnuts to spec would take, what, a whole two minutes? For someone who says they are a fleet owner and would bear a great deal of liability if that was your equipment that failed, especially a steer tire, you're certainly dismissive.
Rust trails out of the lugnuts are ceded as basics in cdl training- rust trail means stud is rusting because the nut is loose. Basic pre trip includes hand touching each lugnut, and looking for aforementioned rust trails as to indicate a loose lugnut.
And 393.205 section C states lug nuts and bolts shall not be missing or loose. Looks like the DOT man was wrong.
There is a difference between rust streaks and just dirt/oxidation. @shogun is right by saying rust means they are loose. Now is that oil or rust Idk from pic. But the missing stud was over tightened.
