I have the RC 2 inch kit, 34inch Nitto Ridge Grapplers. I average 19ish a tank, hand calculated.

My driving is 80/20 highway/city and I drive like an old man.

 

**** that's better than I average right now stock lol. What width 34 do you run? Mind posting a pic of it?

 

Driving like an old man is key to these trucks. Speed kills our mileage.

 

i have a rc leveling kit and run 20x9 0 offset xd836 fury wheels with 305/55/20 (34/12/20) toyo atII extreme tires
2018 titan xd diesel crew cab 4x4
i drive like Kyle Busch ( 1 speed wide open) and get around 17 mpg

 

that's great to hear. And btw.. that tire size is a 33x12.50

 

33/12.5/20 will rub a little
thats why i went with 305/55/20 =33.2/12.01/20
33/12.5 on factory wheels will rub on the front upper control arms

 

Those Nitto Ridger Grapplers always look good on this truck. I think they should have come stock.

 

I get 14.6 MPG stock. I have a PR and I drive like a normal person around here(80 mph empty and 85 with my trailer hooked up)

 

85 towing a trailer? That's pretty stupid
