I guess this would go under the category, "What is peace of mind worth?".
Get 80 then maybe you'll sleep better. I wouldn't as I'd never hear the end of spending a grand on wheel studs and nuts. lol
It depends on the individual,replacing the broken stud along with 2 adjoining studs (1 up and 1 down) is a DOT ruling and I am ok with it lol I would rather have 7 studs made in the USA than 10 made in China. I refuse to use studs made in China even if the made in the USA studs do cost 3 times as much
Some tire monkey really hammered on it with a 1 inch I/R gun with a good air supply to damage those,better check the wheels real close
