The camper I just got (1991 Viking 180) has larger than what I consider "normal" nuts on the lugs. They're either 13/16 or 15/16 instead of the 3/4 nuts I'm used to. Also, they're standard nuts, not actual lug nuts, so the threads of the lugs are exposed. Can I just use standard sized lug nuts? I have a bunch from my Jeep and they will thread on to the lugs.
