Anyone with the BFG KO2 39x13.5r17?

Were you able to fit your 39" BFG Spare in the original spare location?

My 37” Maxsis Razr MT is aired down to 18psi and I only have 3/4” to the track bar. There are two companies that make a rear adjustable track bar with a bend in it to clear the spare. Not sure if that will work on a 39” (aka BFG measuring 38” or smaller once mounted on the wheel).

No, I have the original spare on it for the time being. I am fairly confident that it will not fit was planning on going with the relocation to the bed with the AEV mount….

I'm running the KM3 M/T's in 37's right now, and I'm pretty impressed so far. I measured them at 36", and I'm at 34 PSI after chalk-testing them (may even drop it down a little further). I wanted to go with Toyo's since this is what I had on my last 2 Jeeps, but everything is on indefinite backorder, and they had the KM3's in stock. The KM3's are MUCH quieter (and lighter), but they're not as blocky as the Toyo M/T's. Anxious to see how they fare over time. I've been able to get 30K-40K out of my Toyos with rotation every 5K miles.

I’m aware of Clayton, what’s the other company?

Bumping this--anyone else running these?

@duvinclunk did you end up with these 39's on the 2.5" lift? If so, what wheel offset/backspacing ?

I have not yet. I was having a hard time finding the Shocks I wanted to make the switch. Everything was back ordered for a long time.

are you on Patagonias now? I see you’re also in SLC as am I. Tire inventory is low everywhere.

MFG measure tire height not under load. If you measured once installed that is what is driving your shorter than expected KM3 height. I have the 37x12.5x17 KM3 and they measured true once mounted on the rim prior to putting them on the JT. I was at 36.4 with 35psi

I wonder what they actually measure? Website says 38.5, but also says the 37s are 36.5, which clearly aren’t. My tires have about 2500 miles. The Toyo 37s on our JLUR have about 10k miles and still measure 36.5”.

Had 39s put on last week. Odd your 37s measures 36.4, my 37s measured 35.25” at 38psi.

Looks like you are measuring them under load on the vehicle. Pull the wieght off of the tire and it will expand. Tire height is measured unloaded

I am indeed. Why would it matter off the truck? What matters to me is mounted height.

This is helpful. I have KO2s on my list if I decide to go 37”. Good to know I may need to consider 39s and their 37s would only be about an inch taller than my 35s.

After reading this I’m torn between 37 km3 or 37 ko2. The km3 are on back order, but I can get ko2 right away. My impatience may make the decision
