37” tires on Sport S a good idea??

[Mac]

I have a sport S with max tow (4:10 gears) and 37" with a 3.6 motor. The lift is the Mopar 2" and I have the 1.5" spacers on top of the coil springs. The wheels are Maham and I dont know the backspacing but there is no rub and I rip the tires loose when I take off if I am in a hurry. People say you need this and that but this is what I have on it and drive it daily. It pulls my flatbed trailer with one of the other Jeeps on it fine and get a lot better gas millage doing it then the 2500 Ram I had. Just my two cents on what I have and greatly enjoy. It has been a lot of fun since I took delivery of it in February 2021.

Did you do anything to adjust caster with the 1.5” spacer on the Moper lift? What is the handling like towing with that trailer?

I’m thinking of picking up a set of 37’s for my Sport S. Tow package and 3.73 gearing. Can it handle it? I’m assuming I will need to lift it a bit. What would the recommendation be? A full lift or a spacer kit? It is my DD and sees very little off-roading, mostly dirt trails after it rains to get some mud on it. Not looking to spend a ton so budget is a concern. Pics of your similar setup would be very much appreciated. Thanks!

So i have a 21 Jt Diesel Sports s and a 2021 Rubi Jt diesel i did the mopar 2 1/2 lift at my dealer 37's fit fine very little rub unless super flexed out. The mopar lift was reasonably priced and rides awesome i have 5 other Jeeps and this lift is by far the best riding and handling lift i have ever had installed

Good to know. I was thinking 35’s originally but got sidetracked with 37’s and was wondering how that would work. I think the 35’s with a rubicon suspension plus maybe a slight spacer lift may be the best option from what was mentioned above.

35’s with 1.5 coil liftin front..

No. I have a Sport S. I am running Rubicon take offs and a Terraflex spacer.
With 35s I regeared to 4.88. I am 6,000 feet above you. I rubbed at full flex and I wheel a lot.
You may be able to live with 35s in Florida.
33s were very livable.

With the rubicon takeoffs and spacer did you rub with sway bar disconnected? I know the rubicon fenders are a little higher is why I am wondering.

Tiny bit at full flex

Another Pro the amount of pussy you'll be swimming in.

Well that's reason enough to get 37's.

Like has been said, to do 37’s and to do it right gets $$$$. My suggestion would be if price is the issue do it in stages, buy somebody’s Rubi take offs and 35’s. Save up money buy adjustable control arms, then 3 1/2” springs then 37’s. I live in a hilly area and ended up running my 3.73’s for a couple months before I got my 5.13’s installed due to instal kits being out of stock everywhere. You’ll notice a difference buts it’s livable til you have the coin to re gear. I probably would have done it in stages but my wife and daughter are impatient. Mine is a Sport S non max tow 3 1/2” Clayton, 37’s and 5.13’s.
