I've run both the KM2s and the MTR/Ks and I think I like the MTR/Ks a little better off road, and the KM2s a little better on road. Around here we seem to have a lot of narrow shelf trails that are on a side hill. Or maybe I just notice side hills more because I don't like side hills. In any case, the MTR/Ks have excellent side grip. I think they are one of the better, if not the best, tire out there for side hill grip.

What PSI are you guys running in your MTR's?

Weakest link left will be the transfer case, transmission and engine...

With RCV axles + Dynatrac's + new drive shafts I think I'd be all set

But I have heard horror stories of all the things that get over stressed with 37's

At the jeep Jamboree a week or so ago, there were some gorgeous rigs there that looked massive and very few had 37's, I'd go over and talk to them and normally they just had 16" rims with very full 35's that were 12.5" BFG or MTR K's

On paper I should be able to spin 40's!

Bro your rig is gonna be a monster, you should be fine with 37+ my buddy has a TJ rubi with stock axles and gears (4.10) and has 38x14.5x17 MTRs and he loves it he is just gonna regear to 4.88 for that extra power

Just got back from Rausch today, and saw a guy puncture brand new km2s on a blue trail, I took the same line as him and hey, im here talking about it lol. Lesson is the mtr didn't blow up, I'm happy. Idk what he was doing, could have been driver error but I wheeled blacks and blues all day and do every time I'm out, the Goodyear takes the punishment. I've run Mtrs for my last 3 sets of tires, it's a great tire.

What size? And how many miles did you get out of them?

I just went up to 35" MTR's and I'm very happy with them.

I'm so convinced to get the 35s :) I can't wait, ill go 37s but after I do the regear,lockers and tune. Cause as of now I got 3.21s so I don't wanna overkill my baby

STOCK things get stressed, youre replacing almost everything to heavy duty so you should have no worries but don't take my advice keep doing your research ;)

I did Moab and all the trails around Ouray on heavy Toyo 37's with my Rubi. I only have a C gussets: awaiting to weld up my Artec Truss and install RCV's. It did fine. I was just Leary about going down fast and hard on big rocks. I made it back to Texas just fine! I will say, many of the JK's with 285's did most everything I did. They just bottomed out and had to pick their lines more tactically. I never really scraped my skids! Lol

That's about what I was running on my 33's. The Jeep shop that just mounted my 35's set everything at 37psi and looked at me like I was crazy when I told them I'm used to running 28-30psi.
