Tires and Lift MPG

So I've got my new '12 deleted and tuned and I am loving the power and MPG, getting around 22MPG on the highway @65mph.

I do quite a bit of highway driving to fish and mountain bike so I dont want to trash my mileage.

That being said I would like to get a little more meat on the tires (ideally some 35s) and a 2' lift/leveling kit from Icon.

Any idea how this would impact my mileage?

I got a 3.5" lift and 35's and lost 2.5 to 3 mpg... I'm not deleted, still stock as far as that goes but don't see where that would make a difference as far as mpg lost...

I'm running 3.5 inch ready lift and 37s. 2012 deleted and tuned. I was 20-21 with factory tires. Around 16.5-17 now with lift and 37s.

Ha... I started out around 18 completely stock. Then went to around 20.5 deleted and tuned. Now, I'm around 15 with 37s tuned and deleted.

I wish I had better mpg sometimes, but thats the price you pay to be large and in charge!

Yeah the reason for me isnt so much for looks but to get through a lot of the tough/deep sandy spots on the coast for kayak fishing. I live in Fort Worth so its a bit of a drive to get there so I dont want to lose a lot of mpg and not be able to go as often

You also don't want to get stuck, pay a tow truck, and not be able to go as often

I lost anywhere from 1-3 mpg depending on the speed.

I find my biggest mpg losses to be in town driving (lots of accelerating) and at speeds of 70+

I have a carli leveling kit with 35" Toyo MT's, and at 60 I can still get 18, 65 around 17mpg, then 75 it drops to about 15...

Mind you I am not tuned or deleted, but I'd bet you can probably get around 20 still if you actually drive 65...

All that said, I LOVE my lift and wheels/tires. I feel it made a night and day difference with my truck. I haven't driven in mud, but a lot of snow and ice, and the MT's were better than could have been expected.

Yeah we have snow here in texas today and I literally cannot move without being in 4x4. Those skinny little stock tires are useless. I also noticed now that Im deleted and tuned that when I get on it I cant hold any traction.

Haha yep! I'm in Alabama working right now. We had a terrible ice storm a few weeks ago. Work was shut down for 3 days. 4x4 was absolutely necessary. I was in Iowa over x-mas, and on the hard packed snow with my MT's, it was amazing the traction I would get when I floored it in 4hi. It would slip a little but my gawddddd did it grip well.
