both 80 series alloys and fj cruiser steelies are 4.5 backspacing and with true sized 37s you'll run into issues with rubbing on radius arms on steering lock to lock. when I had the fj cruisers with my MTRs they rubbed like crazy on the radius arms but i attribute that to the MTRs being so big. Probably depends more on actual 37 tire size. I didn't wheel any with those on and switched over to Hutchinsons shortly after (which put the tires 1" further outward to stop the rubbing anywhere)
I liked the look of the steelies but I didn't want to use spacers so i got these after
