I ended up with the 285/70/17s BFG KO2s C Load Rating.I have 265/70/17 at3w on my sport s. If you are not planning on a lift I would go with that setup. Anything higher then 33 or higher look crammed in a JL sport in my opinion. Plus mpg hit and 8 gear struggles and not to mention your speedo will be off 3mph. Some people are fine with what I just said so it's up to you. But 265 and 285 don't seem much of a difference. The biggest difference for me was the price on tires I spent around $600ish on five tires if I went up a size it would costed me $350 more. At that point I rather just buy used OEM Rubicon tires and wheels.
MPG is actually the same.
Performance seems the same.
It is only a 3% difference in tire height, a little more than 1 inch taller, so not much of a difference.
The -6mm offset of the Fuel 17x8.5 rimsmakes it seem bigger than it is, has an aggressive stance.
