you have found the only problem with some wheels. Chevy 6-lug, toyota, nissan and isuzu are all 6 on 5.5 bolt pattern. Just try em til you find some that work. Isuzu had some nice stock wheels, or you can go aftermarket. I have black steel wheels on my trooper now, and they were on a rodeo before I got em.

1992 Isuzu Rodeo 2WD (some assembly required). "If it doesn't fit....Force it!! If it breaks, it needed to be replaced anyway."
