GAS MILEAGE HELP PLEASE!!!

Not to sound stupid but what is the MAF!

 

massive air flow.

 

First thing's first.
Your new tires are larger. 11% larger to be exact.
That means that when you think you're getting 235 miles, you're actually going closer to 260.
It also means that when your speedometer says you are going 65mph, you are actually going closer to 72.

So your mileage isn't QUITE as bad as you think it is... BUT...

The larger tires are heavier. That takes more power to turn them.
They are wider. That's more friction against the road.

The lift hurts the already-terrible aerodynamics of that is effectively a brick with wheels.


You bought a truck. Trucks were not designed to get good mileage. They were designed to perform work... hauling or crawling.
You took an already inefficient vehicle and performed mods that make it even less efficient.

Live with it.

 

Mass Air Flow.

It refers to the sensor in the intake behind the filter.

 

11% is incorrect, it should be 7.4%

 

Thanks for correcting me.

 

Thanks guys for your input!

 

You're right.
I input 245/70-16... Stock is a 75 series?

The massive airflow sensor is when my wife detects that I've eaten too much cheese

 

yeah, stock is 75 series. i think this is the main thing people dont think about when they get a lift, among lots of other things..lol

 

I thought lift and bigger tires give better mileage, isn't that why we bought a truck and stick 500lbs of tire under them?

 

exactly

 

have you checked your tire pressure that will kill your gas mileage i get 250ish to a tank with 22's and 33 m/t's

 

Yes i checked they are good finally figured that i am getting right around 325 to a tank, and about 15.4 miles a gallon. Truck is still pretty new so maybe it gets a little better. Dont care anymore, cause the truck at least looks good.
