Gas mileage

Hey folks. I drive a 2018 that I put after market larger tires on from day one. I’m only getting 16mpg right now which has been consistent for awhile. Anyone have any idea why my mileage is so low?

 

Larger tires = more weight

 

maybe the tires. What size are they?

 

Thats low?? better than mine shit your doing good.

 

Wow you're getting better milage than me.
33x12.5 on 17's
3" lift
15 mpg

 

Okay seriously though....these trucks already don't get great gas milage. Once you put a larger, heavier tire on them it gets even worse. How big are the tires and do you have aftermarket rims? They may be contributing more weight as well.

Also are you lifted?

 

Maybe it's the tires? Hold on, lemme call NASA and ask...

 

My tires aren't much larger (265/75) but they cost me 2 mpg.

 

Mine is 16ish and I'm completely stock.

 

16 mpg?
It's not low

 

I get about 14.7 on a good day, anyone know why "My" mpg is so low?

 

In before:

"If yOu wAnT gOod gaS mILeAGe, GeT a PrIUs."

 

OR:

"My (Insert bigger full size truck with a v8, 'better' gears, and 'better' transmission designed to pull more weight) gets better gas mileage"

 

@Krush how fast do you drive? How much highway/city?

16 isn't bad with oversized tires.

 

Did you factor the percentage increase in tire circumference which registers less miles indicated than actually traveled on the odometer?

 

I only get 16.5 in a Stock Pro

 

These trucks get decent fuel economy when driven gently and left stock. Accelerate slow, keep speeds under 65 and coast/engine brake to stop.

Mods and harder driving lowers fuel economy a lot.
