    I just checked BFG's website and it appears they only make the 305 in a 65 series for a 17 inch wheel. However, they make the 285 in a 75 series. So a 285/75R17 would put you at a very tall 33. The picture below is a generalized measurement for that size and these measurements are with the tire off of the Jeep and not with the weight on it.

    Me personally, I would go with the 315s and adjust as necessary even if more bump stop extension is needed. Both of our jeeps have 33s and we really wished we had gone 35s. They're both getting 35s soon hopefully. However, as far as stock gears, not sure how these would feel with the new JL platform.

    As WJCO said, they can be found in a 305/75R17. Yes, they will be wider than 285/75R17 or what a 32x11.50R17 might be but would be narrower than a 315. You need to remember that the 285, 305 or 315 is the width of the tread in millimeters.

    As far as ride comfort, you have a JL and they are super comfortable running at bowling ball pressure. If you really feel the need to soften things up, run a more reasonable psi.

That said, my experience tells me that it will take a more of the skinny peddle on the right to get those tires up to speed!
    Has anybody done this yet? I'm trying to decide to change gear ratio and install ARB's on sport axles or replace with Rubicon axles. Any advice would be greatly appreciated.

    I wouldn't be putting ARB money in sport axles..... The aftermarket Rubis are $2500 each, come with lockers, and bolt in.

    5 months ago I've was deep down this rabbit hole with my 6 speed jl sport.(classic case of should've bought a rubi) I went to 315/70/17 ko2's on my 6 speed jl sport with 3.45 gears and lost useable power in 6th gear on the hwy and with the sport 2.75:1 transfer case, it was difficult crawling offroad with a 6 speed bc you had to feather the clutch alot. I bought takeoff jl rubi axles for $3800 delivered with brakes and steering components and a rubi 4:1 t case for $1400 delivered. I helped 2 guys install everything and it took a solid 12 hrs and was $1000 which also included adding a RK lift during the swap.(good deal on labor bc one of the 2 guys was my friend and did it for a case of beer) the axle swap by itself was about $4500 for parts and labor.

    Adding ARB lockers and regearing the narrower sport axles with smaller brakes was going to cost as much as doing the swap. My rationale was...for the same amount of money, you get the additional benefit of stronger axles and better brakes to go with the e-lockers and 4.10 gears. It was a no brainer and I've driven on this setup for 8k miles and it's been great...hope this helps.

    Hell yes It helps. Thank you. How are the 4.10s with the 35's? Did you get 6th back? Where did you acquire the axles?

    The 4.10's push the 35's well...I can cruise on the interstates at 75mph in 6th and am getting 18mpg on the hwy and 16mpg around town. I've got a pretty thorough build thread here;

    Very nice. That was great. So the question is, does it make financial sense to buy a Rubicon out the gate or Upgrade a sport?

    Do you want, or need, a Rubicon is the question? Having the 4.1 transfer case, and lockers ready to go, is nice.
