Drove my '98 TJ today. It is light years ahead of the CJ I started in and I still like it a lot. It also has the factory windshield with no cracks. Can't say the same about the JL......
My wife daily drives the JL to work, M-F with an 84 mi round trip. She knocks down 27 mpg and I got 62K miles out of last set of BFG KO2"s. Could have gotten more but they needed a rebalance and I figured I got my money out of them. I rotate every 2,500 miles.
My 315's are on Mopar beadlock wheels in non lock position on JL, 17x8. It is a diesel with a winch so heavy in front, I have a VKS rear bumper, no spare in rear. I run 33 psi front and 32 rear. This seems to be the best compromise between tire wear, comfort and mileage.
I think it has to do with the sidewall height, absorbs the road bumps better. They also drove better on the JL than the 315's do. I attribute that to them being in the beadlock position which makes the wheel wider with less crown on the tire than the 315's have.
This is my favorite thread on JT Forum. No better way to endure 13+ hrs of rain than reading an old 115 page thread and watching "Roadkill" reruns.
Only problem is the 40" tires are starting to look doable.
The JL will for sure be wearing 37 KO2's as soon as the 315's wear out. Problem is the first set lasted 62K miles. They ride so much better than the 315's and I only lost one mpg while they were on. I hated to pull them off but the JT is sitting on stockers right now.
Threw my 37’s that normally live on JT on the JL for a trip to Moab. Snapped a few pics while I was swapping them back for anyone searching in future. Trip was fantastic.
That is super fine and Tank does great work. It looks like it has enough lift to run 47's. You may be able to adjust the Kings and lose some lift so it can sit lower.
I hope you can locate the source of your leak. Driving through a car wash with some friends in the cab with you for extra eyes can help. Pick up a legit cover too. That tarp is going to ruin your paint.
I have 77,000 trouble free miles on my 2020 JL Rubicon Diesel. I just pulled the 37's off my JT and put them on the JL so we can take it to Moab next week for nine days of wheeling, I wish I could find a low mileage Diesel Sport to drive to work to keep miles off the Rubi. I would not hesitate...
