Gas Mileage

I have seen where a lot of members are getting close to 20mpg, I have a 2017 TRDOR LB running 285/70/17s with a Icon stage 2 lift. I am averaging 15.4 city and 16 at best highway miles, is that average for most?

 

Most people getting 20+ are going to be running the 4 cylinder engine. 16 seems pretty common from what I've read of people running heavy tires and a lift.

Also, are you compensating for the difference in mileage from the bigger tires? If you're using the straight ODO mileage reading, your calculations are off. You need to calculate true mileage based on the bigger tire because you're driving farther than a mile for every mile that the truck thinks you're going.

 

This.

My 33s threw off my ODO by 9%.

 

I average 16.4. Will sometime get 17 if I am rolling 65 to 70.

 

I average 17/22 for the most part.
2014 DCSB OR Auto, TRD supercharger, Banks exhaust, Icon lift, 255/85-16 and yes I fixed my speedometer. I live at 5900ft.
