I think you are my long lost brother.2020 JLUR w 3.6 Here. Daily drive and wheel as much as I can.
Had 37x13.5r17 Cooper STT Pros...drove them for a week, took them off and went with 35x12.5r17 KO2s.
All the engines in the JL have enough power to run them, but even with 4:10s you can hear a definite change in the work the trans is doing. It’s clearly working harder to get those big monsters spinning. Do I think this work will affect the longevity, no? I think it’s just going to hit you in the wallet in terms of MPG. More time at higher RPMs.
I took mine off because I really don’t want to regear it yet. I think it is a must to run the setup right and be happy with it. Your Jeep looks pretty bare in terms of mods. If you intended to add bumpers, winches, racks, armor, etc, it would be essential just because of the load you are putting in the vehicle.
I think it is about your core philosophy of how/why you run your rig. I would never run 22” rims because they don’t have enough sidewall for aired down wheeling. I want my Jeep to be the epitome of dependable and capable wherever I take it. So I make my choices based on that. As long as you’re willing to pay to put gas in it and are happy with the way it drives/sounds/looks, do whatever. I doubt there will be long term mechanical ramifications as direct result of running them.
Just wasn’t for me w/o a regear. They do look amazing though (37s in general, not yours).
Also, you did seem a a bit sensitive about your decision to put 22s on your Jeep. I think pretty much anytime someone has to defend their choices in advance, they are sensitive regarding the subject.
