39in bfg km3 on jl rubicon

[Gso125]

I have a 21 jl rubicon on 2.5 Metalcloak lift. I found a good deal on 39 x 13.5 x17 bfg km3’s. They have a 37.5in measurement. I will be wheeling on class 6 roads and blue trails 8-10 times a year and mostly highway driving. Any one running these on a jl stock axels and gears got feedback.

That’s a lot of tire for stock components and the highway driving will suck that’s just my opinion . 35’s on a stock Rubicon do really well for most trails and won’t affect the highway drivability near as much .

Yeah even though they aren’t a true 39 you’ll most definitely want to regear to at least 5.13s. If you regear and are careful on the skinny pedal you’d probably be OK given those trails.
