Isuzu and Nissan wheels will require grinding. Late model 1/2-ton Chevy are hub-centric, not lug-centric. Toyota wheels will clear the Mitsu hub without issue. The 6-lug Wagoneer and Cherokee wheels were made by the same manufacturer as Chevy/GMC and the hub is too small, needs the grinding again. This is all addressing stock, factory wheel types.

Aftermarket rims will have to be checked now, due to the hub-centric market. Just get some Mitsu 16" wheels and be done, no problem. The Montero Sport and Gen II.5 both were equipped with 15" or 16" wheels, depending upon the trim level. The Gen III wheels are hub-centric and would have to be clearanced.

FYI, Toyota wheels are generally deeper backspacing and will narrow up the wheel track. (In my experience.)
