Gas mileage on 35'S

I drive slow as heck, grandma's passing me. Getting like 14.5 stock.
What's the deal? Tire pressure is 38 psi a/t's.

Not 35’s, but this is what I got on 37’s.

I'm at a bit over 19MPG over the lifetime of my vehicle - I use Trip A to track MPG per fill-up, and Trip B has not been re-set since I first got the vehicle. Both right now are at slightly over 19MPG. I've had my Overland right at one year tomorrow, and have had 35s on it since the beginning of October 2020.

Have you recalibrated?

yes

yes

Either my setup is screwed up or yours is...I'm averaging around 15 on 37's...

Sounds about right for a stock vehicle. I was only getting about 18-18.5 when i was all stock and on the 33" mud terrains.

17-18 mpg as a DD

I figured out a method to get better gas mileage, which resulted in me getting 28.1 mpg on a 57.5 mile trip this morning.

Flatbed?

I am getting 12 mpg on the street with toyo 35's on a Sport S with no lift and stock gear ratio. Is this the average or is something not right?

I have a 2021 JTR with 6MT (4.10 factory gearing). I'm on Mopar 2 inch lift and 35s at about 36psi per corner - dealership did the lift and tires for me before I took delivery and they adjusted the speedo.

I am getting about 12.5 average over the first 2000 miles. Manual calculations using "as full as it gets" tankage and odometer readings are pretty close about 12.7pmg.

The picture above is at 6th gear on flat ground (I live in Minnesota and this was taken about 30 miles south of Mille Lacs on Saturday morning - its pretty damn flat). I'm using cruise control and you can see what steady state mileage is doing. The speedo needle is actually at about 67 - it looks like it is at 70 b/c of the perspective... I love my rig but aerodynamically it is a brick on stilts. Everyone who claims to be getting 20mpg or better is selling something. Just my $0.02.

Only about 14 mpg average, with 35" Razr Maxxis MT, but only inflated to about 25 psi, stock gearing.

I'm just putting this out there...Jeep must have a really inaccurate mpg configuration in its system because there no way someone is getting 20+ mpg on 37s or 35s and someone else is only getting 12-14ish. Enough already...some guy on here actually stated 18 average pulling a 4k trailer.

post above is...fuggn legit, I have the same JT that my brother has "other than different color" riding the same roads "speed limit" as he and he was getting 3-4 mpgs more than I. It could happen....I get that...maybe.


However I was stock everything, he had Rubi suspension and 34's...and his speedo was calibrated.....

Must be paint his is silver and mine is Stingrey....More like Destroyer Grey.

I use fuelly (hand calculated) and if there is no hw driving I get a similar 14 or so with my stock max tow. The only thing I am disappointed with in this truck is the mileage. I got similar mileage with a 2001 longbed silverado with a 5.3l.
I have less than 2k miles on it. I heard it gets better. Will see.
