Mine are 18’s. I didn’t want 20’s, which was another reason an XLT was my choice. The GY Wranglers (275 70/18) are 33.2”. I am planning to go to the GY Duratracs (285 75/18) when these wear out… they are about half an inch wider but an inch and a half taller. About 30 revolutions less…
I wonder, when they say 3.31 rear end, what size tires are those based on? I know the AS tires are smaller than the AT tires. They are 32” tall… so I wonder what the ratio actually is with a 3.31 rear end and 35” tires.
Check out Falken AT3Ws... they are a great tire that wears like iron and is an all terrain with a severe weather rating.
Going up to a 35 inch from a 33 inch with 3.31s will lower the RPMs running down the road. You'd probably be fine going to a 35 inch with the torque of the 6.7, but bigger tires mean more weight and more rolling resistance. You will use more fuel.
When they talk the ratio, they are talking about the axle gear ratio(s) (plural for 4 wheel drive). You have 3.31s, which is a higher (numerically lower) gear set which will lead to lower RPMs running the highways. A lower (numerically higher) gear set will have more RPMs at the same speed as your 3.31s (with the same size tire, of course).
Comparing the 275/70R18 and the 285/75R18;
Height 33.2" 34.8"
Width 10.8" 11.2"
Revs/mile 609 579
If you go with those tires, you will use more fuel and may lose some get up and go... but it'll be less noticeable with the 6.7 than one of Ford's new gas engines. Being cool ain't cheap bro...

I'll check out those Falkens... If I am not mistaken, I thought the Duratracs that come on the Tremors are actually 3PMSF rated, however, when I search them on sites like TireRack they specifically state they are not 3PMSF rated... at least in the 285 75/18's... I think other sizes actually are 3PMSF rated... so that's kind of weird I guess. And I did want a 3PMSF tire rated since we will be traveling more and I just figured they would come in handy...
And I figure it will be fine going up to 35's, even with the 3.31's just because of the 6.7... especially with my smaller camper, but sometimes seeing threads like this make me think maybe I should just stick to the 33's... but yeah, I gotta admit.... I kind wanna look cool too!

My buddy has been in the tire business a long time and swears by those AT3Ws... He had them on his own truck when he had them.
As to "3PMSF" rating, I've never heard of that.
And looking cool while burning more fuel is cool... No worries... It's your truck... Do what you want.
If you go with bigger wider tires and wheels that are heavier than the stock ones you will lose fuel millage. Which robes you of that sat in the pants feel. The motor still has the same power but you lost it on the ground. Aluminum wheels could make up for the extra tire weight but be careful as they might not carry the weight.

I have added them to my list, thanks for the suggestion. I am hoping it will be spring of 24 before I need to worry about replacing the stock ones so I should have plenty of time to think it over! As for the 3PMSF, the only reason I mentioned it is because I have seen it when looking at tires. I was reading on it earlier today and it seems like it is just another rating that they have started assigning to tires based on a couple of tests... minimal requirements kind of thing I guess.

Yeah I know bigger tires will cost more fuel, and sure I hope it's minimal... but I would really like a little larger tire in that wheel well! LOL...
