Currently running 1" spacers and have been doing so since the truck was new. What I do not know is if these wheels fit without spacers. These are 16x7 4runner wheels and may fit as the TRD wheels for the FJC are 16" also. Next time I wrench on the truck, I will remove a spacer to find out if they fit. But will most likely stay with the spacers. Spacers is a 4wd topic that some people are passionately against, but I am fine with them. Wheel track is wider, which compensates for the suspension lift and the tire is just at the edge of the wheel arch, where I like it. Flexed the rear and the tire still stuffs the well with no rubbing.
I put the spare on the rear door this weekend and it fit with millimeters between the tire and bumper (ARB). I believe this tire size is THE absolute max you can go with OME suspension. They measure on the truck 34" tall.
