What is the proper backspacing for a 285/75r16 tire on a 2005 Rubicon? I am running the factory Moab wheels but I'm not sure with these size tires if it would be wise to go to a different 16" wheel with better backspacing?
Proper backspacing for a 285/75r16 tire?

Space the wheels out from the hub using hub centric spacers. You can always get wheels with better backspacing but that is more of a subjective preference. I prefer the Moab’s so I spaced mine out slightly with 1inch spacers.
Common issue with Moab’s is that when the tire size increases above the factory 245/75/16s the larger tires start to rub on the lower control arms.

Those are metric 33x11.25s. The stock Moab wheels should be 8" wide with 5" backpace. The 1" spacer @Tronner mentioned should put you at a perfect 4" BS.

I am running 265 75R 16 tires on my Moab wheels without any spacers.
265s are only about 1" shorter than the 285s, so you may want to consider them.
Also keep in mind that a 285 tire will not fit on the stock tire carrier without a body lift. A 265 will.

The Moab wheels are fine. I have run them like this for about 20 years. Adjust the steering stops if you're rubbing the arms.
I am currently running some spidertrax 1.25" spacers, but more to line up the trackwidth with the grooves left in the highway by wider trucks with chains on I-70
I currently have 285/75R16 on the factory Moabs with 2" spacers and there's 1" of clearance to the front lower control arms.
Here's mine on Moabs with that tire size. My F&R springs gave me more lift than I expected, so I took up some of the gap with 35s.
If you're considering changing wheels for more backspacing, I'd go with either a 15" or a 17" for greater options in tires.
