Unless you have been playing in salt water,I doubt that the nut seized on the stud.I would think that more than likely the wheel nuts have been done up with a pneumatic rattle gun,and have been done up too tight and pulled the pitch on the thread slightly,causing it to grab.This is why I won't let tyre places tighten my wheel nuts.A very small amount of anti seize on the threads won't hurt though in future.
