That sounds like they weren't striping, but galled. The metal gets hot and actually sticks(welds) and rips the surface off the stud, nut, or both.

Pulling new studs in shouldn't be a problem, as long as you've room to start them in the hole from the back side. The interference fit is only a few thousands and the holes have been pulled(pressed) once. The serrations at the base of the stud just keep it from turning when you tighten the nuts. The strength to hold the wheel on is the "head" on the stud.
