Interesting thank def app other insight.. I’m thinking of waiting til my 33’s wear out then goto 35’s unless I find a killer deal between now and then. Hills aren’t a huge issue for me. I’m like 80% highway 10% backroads and 10% off road. No towing or heavy loads. So driveability is huge for me, but I also want it to look go while doing it too lol .
If you put it into drive and go you will be fine. If you check the gear though it will be lower than you expect.

I'm surprised to hear a few people say that they saw a big difference in performance going from the 32" all seasons to Rubicon 33s. I can't even tell much difference going from my 32" all seasons to a 33.5" E load. I feel a big more hesitation when I first step on it, but after a second or two it feels like stock, and it kicks out of 8th gear to 7th easier. That's the only difference I've noticed. They might weigh as much as the Rubicon take offs, they are light for their size and load rating at 50lbs. That being said, I wouldn't want to do even 35s without re-gearing.

I'm also surprised at that dyno sheet, the torque curve is flatter than I expected.

This engine is completely wrong for this truck.
I wish we could get the 2.0 Turbo
Depends what you want to do with the truck. For crawling I think I would prefer the flat predictable torque of the 3.6 that sets in earlier even if it doesn't peak as high. Better control.

Shoot I noticed a huge difference from the stock Overland tires to the Rubicon take offs. I can't imagine going to 35s or larger and being happy with it.
I noticed no real difference. Maybe more noise but not much mpg impact, speedometer stayed accurate.
I was totally happy with stock rubicon take-off tires and wheels but will run my originals in summer. Heck, i own them.

Exactly, the 2.0 might put up better peak torque figures, but you have to spin that 4 cylinder to get there. I know a couple of guys with the 2.0 JL’s that absolutely hate that engine now.

Yeah. Go off boost and lose all your torque and control. Get deep into boost and get a sudden surge over something you may be trying to slowly negotiate. Constant flat torque could certainly be better in some offroading situations.

I have 35’s on my Overland and have no complaints at all. That said, I specifically went for the thinnest tire I could find to fit the Overland rim.

I ended up with 285/75/R18, which gives me about 18MPG with the 3.73 gears.
Acceleration always seems fine to me, but I tend to drive pretty conservatively. That said, the few times I have had to accelerate hard, I’ve been pleasantly surprised by the kick.

I haven’t had anything to tow yet, but I’ve hauled a good amount of weight in the bed—again, no complaints with acceleration, speed, or hill climbs.

285 is a 33 +/-
315 is a 35 +/-

So you have 33's not 35's

I have had the same results with my Mojave take offs on my Overland. 285/70/17"s no real MPG change or power issues noted. Dealer did the swap with the TPMS's and flashed the computer as well. It did cost me $216.00 but well worth it.

So you have 33's not 35's
That's true for a 17" rim and 70% sidewall, Overlands have 18's and he has 75% sidewalls.

285/75r18 is a 35x11.5" equivalent.

35's ( 285/75/18 ) made mine considerably sluggish. Down in 5th gear on a lot of small hills on Interstate to maintain 70mph. Put in 488's and problems solved. Rarely out of 8th gear now. Mileage dropped from 20 ( stock) to 17 now.

I have 285/75r18 duratracs on my Overland. Perhaps it has made a slight difference? I do live in the flat state of Florida so I’m not towing up and down mountains.

on a side note, thinking about 37s but worried about it being too much on the axles. Would this be a way of making running the 37s on an Overland a non issue? It’s just for the front axle, would anything be needed for the rear axle?

I noticed about a 1.5 MPG loss over the last 6 tanks of gas. It is noisier...and the steering feels heavier...more than likely due to tires being wider and a bit heavier. But it definitely is noticeable.
