33's on a Sport/Sahara?

[JEEPJL]

Im going with a 2"lift, 20"rim and 35,s on my Sahara.

I've read many posts from those who have done this and the difference is minimal

this is my plan

The Jeep would be a DD and between work (42 miles per day, 30 of it highway), travelling to mountain bike races/training/camping/etc it would end up seeing 25-30k miles per year, hence my interest in the Sahara as it would meet my needs but I'm not a fan of the 18" wheels. I may make the occasional trip with the local Jeep club to hit the sand dunes at Silver Lake or run the 2 tracks on the state land in northern MI but that would be a rare occasion. So I'm faced with (anticipated) decreased performance if I stick 33's on a Sahara or be in the sweet spot with a Rubicon, albeit with lower MPG with both Jeeps but for different reasons. I'd be BS'ing myself, or anyone else, if I claimed that wasn't factored into the equation, especially with driving as much as I do. And yes, I get it's a brick on wheels.

Anyhow, Thank You for the feedback.

I’m contemplating going 255/75R/17 on the Sahara to be the exact same size as factory.

I put 33” on my stock rims, works great, drives great. 275/70-18.

Looks great, and thank you very much for taking time to post that, been wondering while waiting for 2dr jls to be available.

the 275s look like a good option if you dont want to add a lift (no rubbing) and regear. an inch wider will be nice on sand

Question for those who have put 33’s on their Sport or Sahara - has the Jeep struggled to maintain the 8th gear when on the highway or going into a headwind? I’m concerned that the 3.45 is insufficient for that size tire/wheel.

Ha, I haven’t seen 8th since I put my 33” on lol. Other than that I love them. Didn’t buy if for the fuel economy.

I like the look of the wider tires, but my JK had wider and it was terrible to drive on the highway, I put on a lot of miles and wanted to enjoy the improved handling of the JL and haven’t been disappointed. Of coarse I always think I should have gone bigger lol.

Anyone knows What tire size I would need with the following wheels without rubbing?

http://www.blackrhinowheels.com/truck-wheels-truck-rims-zion_5.php

smallest size is 18x8.5
So I assume tire size should be 275/70/r17, am I right?

You can probably get by anywhere from 255-275/70R/18 or 285/65R/18 before it starts to get in the 34” range. I use https://tiresize.com/comparison/ to compare sizes.

Also that looks great, what tire/rim combo are you running on that?

Thanks! Rims are American Outlaw Revolver 17" x 8.5" +10 offset for 4.4" backspacing. I decided to match the 4.4" bs on the Mopar beadlock wheels. The tires stick out beyond the flares an inch or two. The tires are Pathfinder A/T 285/70/17. The spare has a 1-2" gap between the little rubber stops on the tailgate.

Darn, the 275s are really a 32" so I was hoping they would fare better better without a re-gear than the 33s. I wish there was an option for 3:73s.

They obviously did the math too, and are luring people to Rubicon, or atleast us lazy guys

Or forcing us to wait for the 2019 model year in hopes of different factory gearing options. Ordering for 2019 opens the end of September and production starts the end of October.

Wow, you guys are like a jeep scientist...lol. Talking about gear ratios in relation to tire size and weight. Outside of a little road noise and a small decrease in gas mileage my Jeep is fine. If you’re concerned about gas mileage, you probably bought the wrong vehicle :cwl:

33s DO rub a bit on Sport S with no lift ... slightly on the bottom of the plastic piece that bridges the bumper to the fender flare.

I just removed the plastic sub-fender flare pieces. LOTS of tire clearance up front at full turn now. It feels good to have that off my 'to do' list.


To remove them, you will also need to remove the plastic underbody guard.
Removing this will require a 5/16" socket to remove 2 screws, and something to pry out 6 or so plastic push pins. (After the sub-fender flare pieces are removed, you can reinstall the underbody guard)


Removing the sub-fender flare pieces, you will need a T25, a 9/32" socket, and something to pry out some plastic push pins. There are 5x T25 screws that are fairly obvious. The hex head screw is easy to see too. The sixth T25 is underneath and farther inward toward the center of the bumper than I expected. There is a visible plastic push pin centered on the back of the sub-fender flare piece ... that you don't need to remove. The one you need to remove pushes up from the underside.
(This pic shows the T25 screws back in place for safe keeping after the sub-fender flare has been removed.)


The job isn't hard ... just a little annoying to initially figure out why the piece wasn't coming out after removing the 5 screws. I hope this makes things easier for you. (I'm 90% sure of the socket sizes ... I don't feel like going back out to the cold garage to double check.)

What does the front of the JL look like without that under bumper guard? Just by looking at it, it doesn't look like there is a cross member to protect the steering like on the JK, just two boxed drop down supports from the frame rail extensions.

Ive been wanting to take this off, as Im sure its going to rip itself off the first time I reverse in deep mud....but don't want to leave that whole area unprotected.
