37s ??

[Wild Bill]

I just got my new Moab 392 and am wondering if 37 inch bfg’s will fit comfortably instead of the own 35 ‘s without any additional lift. I am not ready to build the beast yet while it is brand new. Any suggestions from experienced members out there? Thanks from Wild Bill!

Here's another thread that some members answered their experiences on for that change.

I’ll be added KM3’s in 37x12.5r17.

From everything I looked up, there’s the potential for a slight rub on the LCA. I don’t care though. The KM3 is slightly smaller than a lot of other 37 inch brand. The C rating with their light weight is a huge decision factor for me.

I don’t care to add bump in the rear. Light trails to scenic/camp sights only. Might add rear bump just because. I always say I won’t do something and then I get that itch later.

Load range C vs D - help me understand why D is suggested?

Now that I have my lift, I am trying to figure out my tires, and debating between 35 and 37 mostly as a function of cost (not excited to have to buy new wheels right now). I found Discount Tire has some Load Range C 37" KO2 KO3 (Whoops, typo) for about $125 less than the load range D or the...

Some of these folks seem to suggest D is preferable to C for numerous reasons. I have no opinion as I dont have direct experience, only sharing information

You’re right. I have come across this often. I think it’s because the taller side wall can get squirmy with a C load tire.

I also understand that not all tires in the same load rating are not made equally and have reinforcement in different areas of the tire.

I’ll keep looking into it.

I’m running 37” KO2s with absolutely no rubbing, although I don’t do any off-roading. I’d recommend the C-rated tires for the significantly lower unsprung weight. On my previous Jeep, Discount Tire accidentally installed E-rated KO2s instead of the C-rated ones. For the week I drove on them before getting the correct tires mounted, it felt like I was hauling an extra passenger.

Think carefully about your actual use case before opting for unnecessarily heavier tires. If you do experience any rubbing at full steering lock, there’s an easy fix: add a washer behind each steering stop bolt. It’s a simple 10-minute job, though I doubt you’ll need it.

One other thought: If you are going to pull the trigger, do it sooner than later. The resale of your takeoffs starts to drop when the nubs are worn off.

Hey thanks. I don’t much off-roading and when I do it’s on the easy stuff. I only live 120 miles from Moab Utah but that’s not my thing I like the mountain jeep roads. Thanks. I think will go with the C rated and maybe 1 or 1.5 inch spacers to level it up I like to be ready for the huge amount of snow we get.

Thanks amigo!

I like the 37 K02 with a C rating on my 20A 392. Adding the 1” bump stop in the rear keeps the little flap in back from rubbing on speed bumps and steep driveways. Great stock ride still. Almost no noticeable loss of performance.
If you really get after it off road the front may rub the inner fender liners. A 1/2” wheel spacer should cure that. And the extra poke fills the outside of the wheel well for just a bit more aggressive stance.
