what drive mode are you using? How heavy is your foot? Are you always climbing hills/mountains? Idling a lot? Towing?

No Towing whatsoever,
Eco and Normal modes - mostly Normal
Short local trips mid-week- light-medium foot (no difference). Occasional heavy on-ramps.
Long highway weekends cruising 70-80

200+ mile highway still crazy low mpg

assuming this is DTE right after fill-up. Note that at 0 miles DTE, you have ~1.8- 2.0 gallons in the 19 gallon tank still.
251 x 1.034 = ~260 miles adjusted DTE (for larger wheels)
260/17 = 15.3 MPG
Not great, but in the range I've experienced if much of your driving is city. (e.g., with same size tires I get 10-13 MPG on the trip calculator for my <2 mile "commute" with stop lights.)
My worst ever tank was 15.1 MPG that included a healthy proportion of 4LO off-road (a sure fire way to lower gas milage:>)
If you are concerned, I suggest actually tracking milage based on the gas you put in and the distance traveled with adjustment for tires.
Also, the DTE appears to be based on the last 30 or so miles traveled, so it can vary a lot depending on what you were doing for those miles just before filling up. (I'd like to know the precise DTE algorithm but it is elusive.)

Correction, the Wildpeaks are true 34" tires so you need a different adjustment. Not positive but I think its 4.3%
so: 251 * 1.043 = ~ 262
262/17 = ~15.4 (Ok, not that big a difference but over many miles it does matter)

AND, those Falkens are HEAVY (like 68# in the E load) - which is a definite factor (my Toyos are 57# in the same size - vs 37# for my stock Michelins - and I think 41-42# for your stock Toyos)

I'm usually in ECO, 60/40 hwy/city and easily get 24+. I got 30mpg last weekend on a 70mile round trip.

The new tires will have an effect for sure, but not 6-10mpg. I've noticed my 27-30mpg range @ 65-70mph significantly drops as soon as I hit 73-75mph. I've never gotten below 19.

City driving will kill your mpg stats...

Very helpful thank you. FWIW I have not used 4WD H or L yet lol. Good to know I'm not out of the ballpark for what I have/do.

My Falkens are C load

Yep - and they are 68# (I'm looking at the Falken spec sheet - looks like they come only in C - so my error above). Makes a huge difference in MPG (this statement is based on comparison of lots of miles with and without heavier tires - I'm not just guessing here. See my recent post in Hybrid Real-world milage.)

just a reminder that if you dont manually reset the avg mpg display, it will show mpg since last reset, not per tank like it did in the 5th gen 4R display after each full tank fill

which annoys me to no end

Will be interesting to see how much it drops in the cold

@spyder40 , what is that phone app you're using? Is it just a basic Log app you adapted for fuel fill-ups and calculations?

I'm about as close as you get to worst-case scenario for mileage, speed limits 45-55 with a stop sign every mile...But I'm still getting over 20.
