Idk. Lost of threads on fuel mileage. Maybe do some reading and see if your setup was mentioned

I was getting close to 18 with 70% highway on 275/65r20 until the Key Bridge in MD came down now I spend a lot of time sitting in stop and go traffic.

I try not to pay attention to gas mileage anymore :) , that being said, I have driven Rams since 2008, I get around 10 if towing heavy and as much as 20 if on the hwy with a tail wind and 3:21 gears. I was surprised how much my mileage went down when I added 33" BFG's KO2's. I was lucky to get 14.5 on my 21 Ram, 5.7 with 392 gears. On m new truck, I have the 3.92's and a 33 gal tank getting about 15 mpg with 800 miles on it.

Anywhere from 12 to 20mpg depending on driver, location, ootions, modifications, time of day, which side of the bed you woke up on, and your wife's attitude.

With threads like this so prevalent in so many different forums, I continue to be shocked at Ram's decision to add 145 horsepower instead of keeping Hemi power levels the same but giving us 30% better fuel economy. ?!?
Yeah, because that would have been so much easier. Why didn't they think about that.

I guess that "giving the people what they want" just isn't in fashion these days? Says the cynical old man...
Hopefully they know what the are doing. Maybe they will sell more trucks and the S/O engine will be better economically. Only time will tell...

Most people buying trucks aren't worried as much about fuel economy. If that was a major factor, they certainly wouldn't buy a truck. Give the people what they want, performance and ability. A truck that can tow, haul, and perform.

I won't complain one bit about the Ram MPG.
MY '24 Laramie G/T has the 5.7 eTorque and 3.92 posi and almost every option..so it's a Heavy Pig!!
Yet, I am constantly between 19-20mpg without much effort.
Winter weather in Wisco drops it the 17-18mpg, mainly do to lower tire psi and winter gas formula.

These trucks aren’t getting 8-10MPG like trucks of decades ago.
Do I expect 30MPG like a hybrid/smaller car? No.
But on my 4th RAM since 06, all with Hemi…. Trying to get the absolute best gas mileage is not in the top 5 reasons I own a truck.
However.. I will say, going from a 15 w/ 3.92 to my current 23 w/ Etorque and 3.21, both Limited, both with 33 gallon tanks, I do get a slight uptick in gas mileage in my new truck. Nothing earth shattering…but enough to notice.

Im getting close to 20mpg with my current set up. 80% of the time my tuner is on stock tune with my 3.21 rear and 35x12.50 R20 tires

Just did a 150 mile trip at 65 to 70 mph and averaged 23.8 mpg (just the interstate part). If it weren’t for the overpasses and bridges it would’ve been even better

I took a trip from Wisconsin to Tennessee over Memorial Day weekend. About 1500 miles round trip, including the local driving while down there. Hand calculated average was 20.4 for the trip, and my truck was pretty loaded down. I did notice that the computer calculated average is about .5-.6 mpg "more optimistic" than reality. Last weekend we were in Iowa and that averaged about 18, but with a pretty stout headwind most of the time. I'm pleasantly surprised coming from the 3.6 and reading others experiences here.

I've noticed with my Pulsar, I get slightly better fuel economy, when cruising on the freeway, with it set to Performance. I don't think I've used stock since I got it, other than to do some comparison tests at the drag strip. Before the 35" tires, with it set to Economy I gained about 1.5mog in around town driving
