So, my 392 is roughly a month out of arrival to the dealership (If I can even put a date on it). I’m in a dilemma for tire sizes and what tires to get. I’m getting a set of Method 312’s that are 17x9 with the -12mm offset. I’m looking at:

37” Cooper Stt Pros
37” Toyo MT’s
38” Milestar Pategonias
39” BFG KM3’s

All of these are 13.5” wide that I’m looking at. I was looking at the Ridge Grapplers too but they are back ordered. I have a teraflex 1.5 spacer lift left from my previous JL I neverput on since I did the mopar lift along with a fox stabilizer, lcas, and a yeti trackbar. The Jeep isn’t a daily driver but will go on the occasional trip to trails or on the highway to the lake. I’m looking to try and get 40k miles out of the tires and also one that will be decent in the rain and snow. I know mt’s aren’t great in the rain. I also know each has its own perks. I am also looking at regearing in a year or two unless the 392 is still able to handle the load. I’m not gonna abuse the Jeep but will do light to moderate trails. Any insight would be great. Thanks guys!

My Toyo MTs are 37X12.50X17. The BFGs are 40X14.50X17s (KM2s). As far as which is better? Purely subjective. I know that does't help. The only thing I will say is that the 392 turns them VERY easily. I know the Pategonias were not an option (just did not float my boat).

LP4s on cowl and 6s on bumper. 9s are a little big. Run them on the Raptor with 6s plus Laser bar.

I’m leaning coopers or km3’s. I know the toyo is a good tire just heavy. The pats won’t last long but everyone and their mother likes the way they ride. Coopers look aggressive and are surprisingly quiet supposedly but I’ve read they get loud after 20k miles and sometimes tend to pull. I’m not too familiar with km3’s but a 39 km3 is only 37.5 inches tall. I’m just not sure about loudness, wet driving, or longevity. Thoughts?

KM3s would be a great choice.

The Pats should be the absolute last option. They will not last long, especially with the kind of power the 392 is putting out. They're OK off road, as long as it's dry....they don't do well when the trail is wet.

These are the KM3 39x13.5 on a 3.5” lift.A 1.5” lift makes me question whether you’ll have any uptravel. Or do you intend to upgrade to something else? I’m also not familiar with the stock 392 suspension, does it already have a lift and the spacers will add to it?

I've been super happy with the cooper at3 in 37's. I ordered three different rounds of tires until I found a brand that was actually available.

I’d actually vote for 37” KM3’s but I think you want 39’s since they run on the smaller side. I have always had great experiences with that brand.

Toyo/Nitto are very heavy but great tires if you’re wheeling a lot in sharper stuff. All MTs from my experience get loud after about 20,000 miles, even when rotated properly. I sold mine for that reason after about 20k.

So the 392 is around an inch taller than a standard rubicon with fox shocks. If I did the spacer lift, lcas, swaybar end links, and shock extensions for now (I will eventually do some kings or accutunes) I should be good. May have to heat and remold rear inner fenders but that isn’t a big deal.

Just ask @cosine he knows!
Only available in a 12.5 width but the Yokohama Geolander MT get pretty good reviews and aren't as heavy as some of the others in the same size.
