I wish I'd put 255 70 17r instead of the 265 70r 17 because they rub slightly on the frame. I got cooper LT 265 70 17r to replace the crappy stock tires. If you go over a 2" leveling kit you'll need a dif drop to keep the front axles from being at too much angle.
Yeah, i went with 255 75 17, and as noted in the link above, there’s slight rubbing at full steering lock (similar to your 265 70). I’m at maybe 1.5” level-lift, and may go a bit higher but havent bothered yet since i havent done a diff drop yet. My bigger takeaway is the difference in handling feel from stock. The 75 profile tires feel more laterally compliant (tippy) at speed, but part of that is changing from stock AT tires to the Coopers which although well regarded by the ‘overlanding’ crowd don’t seem as firm. I’m guessing that a 65 profile, by its lower aspect ratio, will have a bit more lateral support for when we’re sweeping around rocky mountain interstate bends at 80 mph LOL.
I’ll mention for the OP that the Icon UCA kit with sway bar relocation block is a solid bet. I grease the UCAs annually with their handy Zerk fittings.
