Gas mileage (calculated) + tire size/type + gearing info - what are you getting?
 

I have a sticker sr5 prem, 2019... and boy oh boy already eyeing some 285s! My old daily jeep (now kids mom uses it) is on 37s... so these little stockers are tiny!

It's my daily driver, 3rd row for the (4) kids. I drive about 1 tank a week (380ish miles) debating going to a larger tire, but if I spend another 100 a month on gas, might debate it.

So I ask

Vehicle model
Vehicle miles
Tire type
Tire size
Gearing (stock or not)
Driving style
Average mpg (calculated)

Thank you in advance

Stock Gearing
Driving Style is what I guess I'll call moderate? (i.e. I prefer to accelerate smoothly, don't gun it off the line, but sometimes have to punch it on I-10. Otherwise I don't brake heavily, don't feather the brakes like some do, and I coast when I can before braking to stop)

MPG now on my2016 runner stock wheels/tires 19MPG city / hyway ..
just did a 250mile trip reads 21MPG..

when new I only got 17MPG max... driving over 75MPG the runners drop on MPG.. wind resistance ..

Curious if you're running stock front/rear bumpers? Might be a good addition to add to the OP template as well

Stock front and rear bumpers, but I am running a Wilco tire carrier and a list of other heavy things.

Vehicle model - 2014 LE....lots of mods & additional weight....see signature
Vehicle miles - 50k
Tire type - Wildpeak A/T3W
Tire size- 285/70R17
Gearing (stock or not) - stock
Driving style - moderate
Average mpg (calculated) - 15-15.5mpg mostly city driving.
Flat highway 75-78mph can get 17mpg.
But if there are any hills at 75-78mph & cruise control with 285's the truck will kick-out of overdrive quite a bit and your mileage can be less...in the 14's. This is the biggest thing I noticed going to 285's

Vehicle model: 2019 TRD OR Prem.
Vehicle miles: 7K
Tire type: OEM Dunlops at 38psi (most people keep their tires low)
Tire size: 265/70R17
Gearing (stock or not): Stock
Driving style: Moderate for the most part.
Average mpg (calculated): I have put every tank into Fuelly and it says 21.2. (click the link below, the image is incorrect)

Best tank is 22.5 but my scangauge has shown some trips to be 25+

I've never gotten below 20mpg. My worst tank was driving 75 in northern Alabama. I typically try to keep it under 70.

Tips: The sweet spot is 45-55mph. Accelerate moderately enough to keep the eco light on.
Air up your tires
Invest in a scangauge to track each trip and keep an eye on individual tire pressure

Only have figures in stock configuration. Not enough miles yet to tell after modding everything

Vehicle model: 2019 TRD ORP
Vehicle miles: 2880
Tire type: Stock Duellers
Tire size: 265/70-17
Gearing (stock or not): Stock
Driving style: Mostly work commuting, 14 miles to work every day, mix of stoplights and highway, I don't baby it but don't drag race between stoplights either
Average mpg (calculated): 17.0 mpg

After the mods, in daily driver configuration, she weighs 980 lbs more than stock, 33" vs 31.5" tires, 4.56 gears, cat-back exhaust, improved air cleaner, I will admit I have not been driving consistently enough to worry about mileage. I'll post back when I've racked up a few more tanks.
