Everything looks ok except I'm not sure on the diameter for the center bore.

When in doubt....give em a call..

 

Ya, I tried that. They weren't super helpful. Looks like the center bore is too small on these. "Center Bore Diameter (mm): 107.95mm"

 

I read on summit the center bore was 4.25, which is what you want. The OEM center bore is 4 1/8 on any 40,45, 55, 60, 80, 100, 200 (Landcruisers), mini truck/4runner, or Tacoma wheel. Don't know about the Tundra, I heard they went to a 5 lug wheel.

You will want less backspacing on that 85 of yours. I am pretty sure solid axel stock backspacing was 3 3/8, 4 inches to too much. You might run into your tire hitting some steering stuff.

 

Check out the fitment calculator on this website, http://www.willtheyfit.com
You can play around with the size wheel and tire you have now and compare to what your interested in buying.

 

3.75" backspacing is what you want or you'll hit stuff.

Don't ever buy steel wheels! Get aluminum.
