Anyone run BFG KM3 39x13.5x17 ?

Me too - for now I’m going to truss and RCV the front and throw chromoly axle shafts on the rear.

I ordered a set last week, have the same setup and dynatrac ball joints. It should be solid.

Why tire with are y’all running? Would these rub or even fit with with 17x8.5 0 Offset?

@OBJLU - how do you like them? What wheel offset and lift kit are you running? Any rubbing?

Anyone else running these?

Rim size 8.5-11". Rubbing or not depends on your backspacing, lift, fenders, fender liners.

I love em but I did have to buy wheel spacers which I am not fond of. I am running a 4.5 inch lift, now running now that I have the spacers and additional inch of bumpstop

Considering getting these 39 KM3s. Currently have Rubi Dana 44s and running the 3.5” Metalcloak Gamechanger. Anyone running a similar set up?

Took it to the dunes and had no rubbing so far. I’m sure at full flex there’s probably rubbing towards the body. I bought the wheel spacers but I don’t want to run them tbh.

I'm running them. 2.5" Currie lift. No fender trimming. The only slightly rub the inner plastic liner in the front. The rear I had to remove the small plastic lower rear plastic fender/bumper piece.

That's what I'm thinking about.. I plan on adding Chro-mo axles in the rear and RCV's in the front. Hoping they hold up. I've seen people with 38" Pats with stock axles been the bag out of it and it held up. 38 Pats and 39 KM3s are pretty close in size/weight

Tire weight has virtually nothing to do with drive line reliability, it's RXF (Radius Cross Force). 1" bigger tire is a 1/2" longer cheater bar. Conventional wisdom is a JLR can go to 37". Bending the axles has nothing to do with tire size or weight although It seems folks who run big tires in KoH action are more likely to bend an axle. Ditto for breaks, has virtually nothing to do with wheel/tire size/weight. The breaks stop the weight of the moving vehicle.

I plan on going with Wrangle MT/R with Kevlar 38X14.50R17 because I want the widest tire at 7 PSI in the sand here. I'll go with RCV in front and Yukon chromoly rear shafts. Given my rig is 100% off road with a 4:1 xfer case, I won't need to re-gear.
