33's or 35's for my new diesel ??

[Mikemann0]

2023 Sport Diesel w/3.73's , Has the factory 245's right now but looking to go up just don't know if 35's too big 1 for fit (suspension staying stock) or 2 33's perfect or not - I will stay stock height for a sport and I do tow a 12 ft double axle with my KRX1000 on it weighing in at 3700 lbs , Also going with the Quadratec classic white wheels 17x8.5 with a 5.2 (+11) backspace whenever they are back in stock , Thanks in advance....

I have the Rubi take off tires on my Sport S Ecodiesel. No complaints while stock. Was still getting 25+ mpg.

Stay with 33's for one reason . Easier on tranny. If your towing on a regular basis you are going to want to stay with 33 if only occasionally I would venture into 35 and a lift

I do only tow occasionally but I do not want to do a lift on this Jeep been they're done that want to leave this one be and enjoy the mileage the diesel should bring , I do believe after some more research 32s or 33s are probably where I'm going to be

I did look at that option also seeing some of the Willy's take offs , that is a possible good option

32 looks good with stock suspension sport, and won't change effective gear ratio much or speedo, 33s look great on ruby and Mojave’s. Good luck with your search

I wouldn’t worry about the transmission with 35” tires, throw that comment to the side.

I tow a ton on 35” E tires with my ecodiesel.

The Trans is a real ZF, not a Chrysler copy.

The ecodiesel is a fantastic engine, don’t let all the negative comments steer ya.

it will have modern diesel issues, but the transmission is far superior to the trans in the 3.6.

You can roll 37” tires on the 3.73’s and tow… just be aware of the heat it will generate.

First Congratulations on the new diesel!! I ran 35 on my sport s stock with little rubbage. But honestly without a lift I would go 33's . My fuel mileage changed a little with 35's now I run 37's on both my Jt's 21 Soprt s and 22 Rubicon both ecodiesels and still get low to mid 20's depending how im driving did get 27.2 from Cheyenne,Wy to Hot Springs, Sd and hand calculated

With all the weight I carry and the camper. Now lifted I'm lucky to hit 22.

I’m around 21.5-22.5mpg on a 4 1/2” lift and 37s. I’ve owned it for 16 months and have 30k miles, so I drive a lot. I do tow but it’s a bass boat so not much weight.

I would say maybe throw a 1” spacer in the front and 35s and don’t touch anything else. You should still be able to see 25mpg on a regular basis.

I did toss around the idea of a spacer and 35s didn't want to mess up the ride by doing anything with the suspension also with a spacer I'll lose my rake and don't want to be sagging while towing.

The ride won’t be changed as you’re not changing anything in the suspension. Still riding on stock springs, shocks, etc. a 1” spacer will still have some rake to it. I did a 2” and 37s when I first got mine and it sat dead level which is what I wanted. Also at the very least if you decide to add a winch or bumper down the road it won’t look like a stink bug with the 1” spacer in there.

This was with a 2” spacer and stock tires, so you can imagine a little lower in the front with 1”
