BFG makes the km's in a 255/80/R17. Probably about the best you might find.
It's the KM2 that they make in that size. What is load rating? C is best for a Jeep, IMO. Some guys prefer D. But E is way to blanging stiff.
Are any other tires made in that size in load C or D?
235/85R16 (33 x 9.25 R16) is an interesting size, but is only made in load E (to stiff for Jeep), and I prefer 75 aspect ratio for stable sidewalls (better cornering and flat contact patch at a reasonable street pressure).
With combination of load C, 75 aspect ratio, and wheel approx 2.5" narrower than tire section width, I get flat contact patch at nomal street psi. So good traction at street psi and no need to air down for most off road adventures. Airing down only needed for hardcore uphill sand dunes or hardcore rocks. No need to air down for moderate wheeling or Winter roads.
These are reasons why Jeeps and other SUVs usually have stock setup with P or C tires with 75 aspect ratio and wheel 2.5" narrower than tire section width. The engineers usually use this formula for a good DD.
I like to use that setup for a good DD, but do so with a taller than stock tire that is stock width or up to 1.5" wider than stock. Typically I prefer 1/2" to 1" wider tire than stock. It's easily possible to do that with tires taller than stock and keep 75 aspect ratio. Even possible with tires much taller than stock by adjusting wheel diameter so that aspect ratio stays near 75. Also adjust wheel width so it stays 2 to 3" (ideally 2.5") narrower than section width.
I came to these conclusions after running 75 and 85 aspect ratio narrow tires in the past, as well as having tried medium and wide tires too. Having tried an assortment of tire of tire sizes I realized it's not as simple as narrow vs wide. There is more going on: Vehicle weight, tire load rating, tire section width, wheel width, and aspect ratio all combine to affect sidewall stability and cornering, contact patch at street pressure, traction at street pressure, how much air pressure you run on street, ride quality, and gas mileage. Setup properly there is no need to air down for Winter roads or mild to intermediate off roading because tire already has good contact patch and traction at street pressure, and decent ride quality if load C.
