I really hate to break with the pack but I wouldn't go out and start replacing the studs just yet. When I look at the pictures I see 75% of the stud untouched. I'd get a metric die and clean the threads up. Not a thread chaser, a die. Then I'd do some careful measurements to see how much of the studs would be engaged by the nuts. If the nuts engage at least two thirds of the stud, I'd just drive it. Now if you have driven the truck with the incorrect nuts, then I'm with the pack. I'm sure the studs have been flexed and that's never good.
Sorry this is wrong.
I see at least 1/2 of the threads on the front 3 studs are messed up. The studs are cheap, replace all of them, and all of the lugs on each wheel you tried to force the incorrect lug nuts onto. Gene
