I'm trying to find out whether I got the right tires on my 2020 JLU Sahara from the factory. It has the 18" wheels.

Here's the possible issue:
On both the Jeep Order Guide, and with the online build configurator, it says that when you get the Anti-spin rear differential option, it includes "All-terrain tires" or "255/70R18 All-Terrain Tires." This applies for both the Sahara and the Sahara Altitude. (It could apply for other variants too, I haven't checked.)

Mine, which has the anti-spin diff, was delivered with Bridgestone Dueler H/T 685 113T's. They have a standard highway tread pattern, which looks like it will be worthless in snow. I wanted the AS diff and the tires so I wouldn't have to worry for driving to winter sports.

Tire Rack describes the Dueler H/T as "Highway All-season," and calls two versions of the Dueler A/T "On/Off Road All-Terrain." So, I am thinking that Jeep is delivering vehicles with the wrong, standard tires when the AS diff is ordered.


So, my question is this: on your 2020 JLU Sahara with 18" wheels,
1. do you have the standard rear diff or the anti-slip rear diff, and
2. what tires did it come with?

I want to know if FCA is pulling a fast one by supplying the same tires for both. If so, I want to get my proper tires. Thanks.

anti-spin rear diff your Jeep should have come with A/T and not H/T. Go back to the dealer and have them check and make sure you got the dana 44 axles with the anti-slip diff and if they got that right claim your A/T tires. My sport came with the Wrangler Kevlar A/T tires.

@Pilotjeep

Why don’t you start by posting your build sheet here. Then we can go from there.

Replace the “X’s” with your VIN number.

The build sheet specifies anti-slip diff, but Bridgestone all-season tires

I hadn't considered that it could have both the wrorn diff and tires. I took a look at my diff cover, and it doesn't match any Dana identifier pics I can find online

That picture doesn't match. Mine has the plug towards the bottom of that flat, has angled rather than rounded upper and lower left corners, and has a different bolt pattern.

That pic is like other Dana 44 pics I see on identifier pages, which also don't match mine. For example, the one in the page that you posted matches the "Dana 44HD" on this page: https://www.randysworldwide.com/differential-identification-dana/ , but not the Dana 44.

OK, I see that - it's the D44. And hopefully LS per the build spec sheet.

The question remains, why do I have highway tires when all specs available when ordering say that it should have A/Ts
I’m a bit confused here, your posted build sheet lists...“255/70R18 All Season Tires” and the Bridgestone site says the tyres you have are “all season” so I’m not sure where the confusion is?

that’s a question you will have to take to your dealer. Honestly don’t understand why you haven’t at least called them.

All season tyres being different than all terrain tyres ...... seriously, that’s just a weird way to spell tires.

Yes I understand there’s a difference. The point I’m making is that his build sheet says ‘all season’ and that’s what he’s got regardless of how we spell tyres lol
