MPG's after adding new tires

[kophoto4x4]

So, after adding tires and a little over a full tank of gas I am getting about 17MPG. I live in SoCal with it mostly being hills I am going up and down and a mix of highway and city with generally a decent amount of traffic. I included the specs of what I have added. There is also a small lift in the front about 1.75" to level out the front with Kings.

My stock MPG's without lift and aftermarket wheels and tires I was getting about 18-18.5 MPG and that is without the air dam. I also drive like an A-hole most of the time slamming on the gas a lot so I am probably on the lower end of the MPG scale. Does anyone else have a similar experience with this setup or larger?

Tires:
LT285/70/r17E Falken AT4w's (just under 33" tire)
Wheels: 17X8.5 | 6X139.7 | +25 offset | 5.73" backspacing

Not bad numbers with the 285s at all. Can't get over how good those wheels look on that color.

I'll let you know what my MPGs look like after the 37" M/Ts go on the hybrid.

I'm guessing 12 MPGs... maybe 13? lol

I absolutely love the color! So many people ask about it too it's the first thing haha

Yes I am super curious about the 37s but I feel like with the hybrid it won't be too bad cause you'll get a good boost from that battery but it'll be tough still with so much more tire to move
