35's on 3.73's (Overland)

[HjStrater]

Either buy new 33’s or find cheap rubi take offs, you’ll be disappointed in how the Overland performs on 35’s. This is a fact.

No, this is an opinion.

I run 35’s on my Overland and I am not disappointed in how it performs. It’s all a matter of perspective.

OP,
Make sure to update the tire size using a taser or something and you will take a few MPG hit. I don’t find it to be a total dog accelerating, but it’s not the same feeling as a 300hp sedan either.

Will it work? Yes
Will you lose 4-5 MPG on the highway with 35's and a lift? Yes
Will it be sluggish on start and on the highway? Will it hunt for gears and downshift at the hint of a slight incline? Also yes.

I ran on 35s and 3.73s with a 2.5" lift daily driving for about 2 years and it was fine. Upgraded to 4.56 earlier this year (I don't plan on going to 37+ until I get another DD) and it drives better. Fuel mileage didn't really change and is about what someone else mentioned but there's no more sluggishness to it.

Really depends on your use case. If you DD mostly on flat land with occasional off-roading I wouldn't worry about it (even though that is my use case I still upgraded). If you are in the hills/mountains or on the trails frequently I'd consider regearing sooner.

ok so you’re not disappointed, but it’s not perspective. It’s a fact it’s underpowered with 35’s. 100% facts.

You keep using that word, I do not think you know what it means.

It’s not underpowered. I climb hills, I pass on the highway, i off-road, I rock crawl, and I have never “ran out of power”. It would still do all of those things with 4.88’s just at a lower RPM… That’s where the perspective comes in, if you want everything to feel effortless, if you want it to feel like a V8, first off your going to be disappointed no matter what, and second is it worth the money to feel that way.

I’ll even play devils advocate for you and say if your off-roading involves playing in the dunes or in mud pits or if you have the 6MT my answer would be different. But for most people, for a DD, it’s fine.

I’ve posted this before when talking about gearing, so I’m just gonna copy/paste here for this one:

As for the gearing issue, the 8 speed auto picks up a lot of the slack when it comes to gearing.

For a comparison, the wife’s 20 Willys JLU came factory with 255/75R17 and 3.45 gears. It drives perfectly.
My JT was equipped with 255/70R18 and the 3.73 gear. Swapping to the 295/70R18 changed my effective gear ratio to 3.49, which is still a bigger gear than hers has from the factory. After recalibration with Jscan, I have zero drivability issues. I still see 8th gear on the highway

35's and 2.5 inch front lift for over 2 years on Sport, no re-gearing. Lost about 2mpg, however I still got 22mpg on last road trip. I mostly average 19 mpg combined in the summer, 17 mpg in the winter. Factory wheels/tires make the truck look disappointing for that price range.

That’s an opinion…not fact.

I’m firmly in the “you’ll notice 315/70+ tires on 4.10 (or lower) gearing” camp. It’s not “underpowered” for what the average person will need it for. With the eight speed, it’s still fairly responsive if you get on it.

Planning on hauling around a huge travel trailer with your JT? Keep the factory wheels and tires (what I did) or regear.

Daily drove my Sport S on 35s with 3.75 gears for about a year. It took one drive from South San Francisco to Sacramento and I was shook. I thought the transmission was going to blow. 4.88 regear couldn't come soon enough.

That idiot must of had 4 flat tires ?

Keep telling yourself that bud. You clearly know more than the engineers who designed the vehicle with 31” tires at 3:73 gear ratio for multiple reasons. Cool, so you threw 35’s on 3:73 and I’m sure you never see 8th gear, but hey it’s not a performance issue it’s just “perspective.”

“It’s not “underpowered” for what the average person will need it for” - that to me sounds like an opinion. If you think slapping 35’s on a vehicle that is tuned for 31’s has no impact on how the vehicle performs you’re fooling yourself.

Ok. You win the internets.

Sounds like someone regrets their 33’s and is justifying their decision to me.

2.5" lift and 35's on my Overland and in my opinion it drives fine. I don't drive fast or hard and I see 7th and 8th gear all the time on the freeways. Yes there is a noticeable difference with the 35's but it's not that bad. The JT is a turd to begin with so I'm not complaining. I won't regear unless I move up to 37's.

Not sure about what size tires to choose, we can help you make the right decision.

	Highway Driving, Good Fuel Economy yellow​
	Daily Driver, Best Overall Performance green
	Most Power and Towing, Reduced Fuel Economy blue

This chart is based on 65 MPH and a gear ratio of 1:1, on a manual transmission in 4th gear. Please NOTE: If you have an automatic transmission your RPM will higher due to slippage in the transmission and the torque converter. With an overdrive transmission your RPM in overdrive will be 15% to 30% less than indicated.

So did you set your gear ratio to 3.49 in JSCAN?
