2023 Gladiator Mojave recent trip and mileage

[Lunentucker]

I am aware exactly what my tires are. Some websites give exact tire measurements. My 37's measure 35" tall when inflated an on my truck

Discount tire tells the exact tire size, for example, the Nitto Ridge Grappler 37's are 36.77" on their website.

I'm really not trying to argue what you're seeing with your own eyes.
If it's all accurate, you have a Unicorn for sure. I've never seen anyone with 37 MT's out in the wind like that get anywhere near that kind of MPG on highway, much less at those speeds.

All I can tell you is what I'm experiencing. I do drive it like my grandmothers riding shotgun, nice and easy, that DOES make a difference in mileage for sure. I normally get about 14.5-15 mpg around town, but if I really try to get better mpg, I can get like 15.8 mph around town. I will re check the AEV tire calibration and get back to this post in a few days.

Im SURE the mpg in these trucks can vary like 3-4mpg difference between driving easy and hammering it all the time.

Same. Cruise set at 75 on 37s with 3.73s (in 4th) or 5.13s (in 6th) I get about 15 in no wind, about 18 with the wind and 12-13 into the wind.

Other than driving habits, which I often do the same as you, the largest factor affecting MPG I have seen is the difference between winter blend and summer blend. My MPG went up by 2 as soon as the summer blend came back.

I havent noticed. Ive had the truck for 7 months and now have 4,500 miles on it.....over 1,000 driving back and forth from CA

No way this is possible. Just not. Something isn’t calibrated right or you have different sized tires than you think.

I get 10 around town, LUCKY to get 16 highway. That’s with “only” 35s. And only 10.5” wide tires (less rolling resistance) and the same AEV lift.
That’s just how it is. For everyone.

I can promise you my tire size ARE correct. What I WILL check is the calibration on the AEV unit. Either way, some people get better mileage than others in ALL cars, so many variances. You guys act like Im making this shit up. The ONLY variable here is IF my AEV calculation is wrong, Everything else is 100% accurate.

Definitely not trying to argue with you, your picture proves the Jeep is measuring 19 mpg. I think all we are saying is to double check your config to verify what its seeing is accurate.

Best case scenario, you verify you are getting good mpg and can keep on doing so

Worst case scenario, you are on a dark highway somewhere thinking you have plenty of miles left in your tank , run out of gas in the middle of nowhere and end up in the next From Dusk til Dawn movie

All the unbelievers...
My Sport S, with 18" stock wheels & tires (from a Mojave,) gets 23+ mpg combined, as long as I drive conservatively.
I don't see why his 19, even with bigger tires, is so hard to believe.

Good point - Thats why I carry a pistol locked in my center console and a rifle whenever I travel- and no matter if my mpg is "off" I can still get an accurate reading from the fuel level.

I haven't had a chance yet to go through and see the calibration, but I did notice the AEV speedo claibration requires me to put in the actual size of the tire while it's mounted on the truck. So, the tire is a 37x13.5r17, actual size is 36.5" and on my truck they are 35.125". AEV uses the 35.125" measurement. Possibly this could be a discrepancy?

Another vote for totally possible. Similar mods. I have seen just over 19 on longer trips. I have also see around 17.5 just depends on how I drive it and which was the wind is blowing.

Any difference between what's input and actual is a discrepancy, and you should see that easily by comparing your speedometer reading to a GPS reading from your phone with Maps, Waze, or anything that shows GPS speed.

This is why I said to measure from the ground to the center of the hub and multiply X 2. It's the easiest and most accurate way to get your tire's true diameter.

Stock 2022 Mohave best I can do is 18.5mpg and that's on the highway around 70 mph.

This is absolutely what we are talking about.

Here is some theoretical math, of course real tire size measurements will vary, and this doesn't take into account that the correct gearing is set...

Going up from the stock 285 (33") to a 37" tire is something like a 12% change to the what the Jeep sees vs what you're actually travelling. The Procal/Tazer/JScan will adjust to compensate for that 12%

Conversely, if your tire size is entered OVER what it actually is, your vehicle will think it's going farther per revolution of the tire. This means your MPG will appear to be better, but your odometer will show more miles than you actually have driven. The Jeep thinks its travelling 116.25 ft per revolution when in reality it's only going 103.67 ft.

When you're adjusting for tires/gearing, the basic rule of thumb is to round slightly down.

Using your numbers as an example with the AEV Procal, I would enter something like 35.10 (vs actual measured tire size of 35.125) Verify your speedo with GPS. It's also good practice to measure your tires and adjust again as they wear down, I will usually check mine once a year.

I am not a Doctor, this is not medical advice, YMMV...
