That state line transition can be crazy. People never believe me until they feel the difference for themselves. You don't even have to see the state line signs to know. It's like braille for your butt.

Best explanation I’ve heard. I’ll have to start using that

I remember South of the Border. Never understood the place.
I've seen the signs, I’ve even seen it from the highway, but I've never been.
nice looking ride you’ve got. get yourself some good tires and just go out and have some fun for a while. this will give you time to figure and refigure what you really want/need for upgrades. merry christmas young jeeper!

Worth doing research on load range C vs load range E tyres. The 255/75 r17 KO2 looks to be load range E in the US.
OP
That’s something I hadn’t really thought of. 255/70r17 KO2s are load range E.
From my understanding, E is going to be thicker, heavier, and more durable. So it won’t flex as much when aired down, but it is less likely to break when off-road? It’s meant to hold more weight?
And then C is going it flex much more when off-road and aired down, and it’s softer so it’ll be a smoother ride on road, but it’ll be less durable off road?
I’ve got a very basic understanding of it… I think… Does it matter all that much? It’s seems like a large amount of people on the forum like KO2s despite us all having tjs which are relatively small.

Tires have to be number one on the list. A super capable $100K Jeep cant get very far without decent tires.Tires are definitely the top on the list. And, most expensive, unfortunately. Thanks!
That's the gist of it. These TJs are relatively lightweight, so the E will have a harsher ride. Not all KO2s are "E" rated. My 33x12.50x15 KO2s are "C'' rated. Talk to a tire guy, tell them about what size you want and see if they can find a "C" rated tire.
Load range E are meant to carry heavier loads (standard equipment on 3/4 ton and 1-ton trucks) and often do have thicker sidewalls for that reason. Some here prefer Es for added piece of mind in the rocks. I've personally only had Cs on my TJ and have never had a problem in the rocks we have here in the desert.
For a DD, I'd lean toward a C on a light vehicle like the TJ. BFGs do have a good name, but really any of the big name brands (Goodyear, General, Cooper, Toyo, Falken, etc.) should provide you good quality, so I'd determine size, AT vs. MT and load range first, and then see what options are available that check those boxes.

Everything I see online (after looking super quickly) is E for KO2 31s, but I see many KO2 33s that are C. I guess I’ll just have to do a bit more research.
No they're not, they just look that way to some. They have a full heavy steel tub on a full steel frame design and are significantly heavier than most cars. My previous TJ was 4100 lbs. on the local truck scale.
It is his daily driver. He lives in an area where front yards have been paved over decades ago (sometimes that's literal). According to our State DOT we have nearly 80,000 miles of state roads, of which 95%+ are paved. We have to actively seek areas without pavement around here. Of course, if he crosses the NC/SC line, that pavement instantly turns into a pothole-dodging-rock-crawling event at speed.
I’ve got 3 TJ’s that are DD’s for me and my twin sons. We all run MT’s. We are mostly all on road. Who isn’t if it isn’t a dedicated trail rig? Practical? Who cares. It looks bad ass! Besides, the OP in the title wants to improve off-road capability

Context. How much does a typical one ton truck weigh that engineers suggest using an “E” rated tire on?
I do agree, they are not light. I wonder what the weight distribution is on them. Anyone know and can point to a source?
I say spring for the km3's rather than ko2's. You will thank me later.
My TJ was about 50/50 last time it was on the scales. Things have changed a bit since them, maybe I'll weigh it again.
