Thinking about switching to 37s on my daily. Bad idea??

[namwop]

Unless you had MT's on your jeep before putting the All terrains on then they aren't going to ride better than the street tires that were on it. Now if you had a MT then ok. If you lift it then that is going to allow air to get under it which is going to throw the already non aerodynamics of the jeep off more. If it would ride better lifted and on All terrains then the overland would come lifted with all terrains on it.

The tires are the same as stock just bigger. The new suspension components make it feel like a better ride to me.

I guess that's all that matters if it feels better to you

Yeah it was a pleasant surprise lol

On my 22 JTR I have BFG KO2 315-70-17 and they are wide. About the same weight as BFG 37s. Thinking that my MPG won't change much as the 37 is only 36.5. The narrow 37 might even look better with less poke. I have a full size spare and a 37 will not fit there. I do DD mine with some moderate off. road . I don't know how people are getting 16+ mpg as I have never seen 16+. Possible tire issue as they are really wide.

Actual height is 35.7 mounted and that was in a 2010 JKU. They are light though.

Width doesn’t affect MPG as much as tire diameter. Those tires should only be a little over an inch above stock in terms of width. If you havent updated the computer for the larger tire size then it won’t read your MPG correctly and your shift points may be off.

I have 37 x 13.5 Ridge Grapplers, Max Tow package, 4.10's . . . I average 18.5 MPG city and highway combined, with 80 to 85% highway driving.

Not possible on a 2020 JT 3.6 AT with those heavy tires, a 2.5” lift and a winch.

I daily'ed 35's with the stock 3.73 gears for some time and it wasn't great but manageable. I now have 37's Nitto Recon's with 5.13s and there is a difference in drivability. The gears made up for the diameter and then some on the drivability and transmission gear selection, but there is a noticeable difference on the feel of the steering and brakes. My PS pump just isn't quite up to the task, and I can "feel" the tires muscling the steering components on back roads at speed. 90% of the time, it is not noticeable but 10% of the time it is very noticeable.

I am looking into steering upgrades in the near future.

To follow up on myself, lol. I ordered the following parts yesterday for my steering upgrades for the 37's. I was on the fence and yesterday had to do a bit of in town, stop and go, parking lot maneuvering and running around. I noticed on a few occasions I had to yank the wheel when changing directions, and it felt like the stock pump just isn't up to the task. That and I can "feel" the steering flex on a rough road. It gets worse with the travel trailer hooked up.

I have a 10 day wheeling trip in the Rocky Mountains in two months that will involve picking my way though rocks, snow and shelf roads. I decided to pull the trigger in enough time to get the parts, install them, work out any kinks and be ready for my trip.

For reference, this all cost about $1,800 adding in a new alignment and I am looking at about 2 weeks to get everything in.

Apex Chassis 2.5 ton aluminum steering kit (no flip) with HD ball joints
Apex Chassis stabilizer clamp and Fox 2.0 stabilizer
Apex cooler and steering booster kit

I'd say all those upgrades will help except the fox 2.0 stabilizer. I got it on mine and it's not much of a upgrade if it's even a upgrade from the stock stabilizer. I only still have it on because I got the Rubicon fox shocks and it matches those. Next Stabilizer I get will be either be the Teraflex TS stabilizer or the Fox TS stabilizer. Driven JTs with both on and you can definitely tell a improvement on the road feedback with the through shift over the 2.0, it's a drastic difference for the better. Just my 2 cents on it.

I love these statements, better than stock, really on 37's and a lift better than stock. I guess better if you prefer a rougher ride, LOL! I have lifted a ton of vehicles over the years and non are a better ride once lifted and then throw on aggressive tires

Everytime is see these words i think the exact same thing. I don't understand how a lift and larger tires is improving all these rides and in some cases increasing MPG.

The only thing i can think, other than confirmation bias, is that these trucks come with a little too much caster from the factory and once a lift is on, this brings it back to a more comfortable feel?

or like you mentioned above, MT -> AT, or maybe even less psi/more tire giving it a softer feel?

Why does better ride have to be softer? My rubicon on the clayton springs with fox 2.0's and the grabber ATx's in 37 rode much better than the factory marshmellow suspension and the falken's. It was more controlled, less body roll, less oscillations after bumps, and better dampened. Also tracked straighter with the better caster from the front arms.

Lifted will definitely ride "different" but if you get a good pair of springs matched up to the shocks and the weight of the truck no reason it has to be a rattle trap or some horrible ride.

My Glad is more stable and rides better than stock, especially over the rough stuff at speed. It comes down to a quality kit and dampers. Cut corners and yes, they often ride like crap. lol.

So going up higher makes a jeep more stable and putting on more aggressive tires makes it ride better. Doesn't really matter what kind of quality you buy, throwing the geometry off from stock by going higher is not gonna make it more stable. Throw on the tires and then your gonna feel the road more. I'm not saying at all that it doesn't ride well or that it makes noise, but if you lift something, anything no way it's more stable and if you take off street tires and put on M/T or A/T tires your gonna feel the road more. The best stabilizer you can buy isn't gonna correct that.

Over the rough stuff, I 100% agree. And when installing better components in the lift, im also on board.

I guess my comment is more directed at the folks who add lift/tires then say it drives better on the highway, and is getting the same or better gas mileage

I feel like a curmudgeon even talking about it, which is not my intent. I am by no means at all trying to gate keep anyone from going to 37s, and I don't necessarily want to call out the ppl that have had good experiences adding them to their rigs.

I am just giving my opinion from my own experiences. I have never had an increase in mpg or gotten a noticeably better on road experience when adding off road specific upgrades to any of my vehicles.

 

[Stitchedupseats]

37” KM3. Mileage on interstate at 70 is 18+ mpg. Drives better than the rubicon falkens to me.

did I need 37s? No. Do I need 2 trucks? No do I like both of these things. Yes. ?
