In the parking lot of my office today, there happened to be a 91-92 Cruiser parked next to a 4Runner with these same wheels on them. The wheels on the Cruiser had "15x7JJ10" cast into them, the 4Runner's had "T15x7JJ OFFSET8" cast into them. the dish on the cruiser wheels was noticeably deeper while under side by side comparison.
While the offset/backspacing difference may not seem like much, it can cause interference.
I'd hold out for the correct Land Cruiser specific wheels. They come up for sale occasionally on Mud.
