How much does your lift affect your MPG?

Stock 245/75R16 Dungflops at the time. 5 speed manual

Hey guys as I'm reading I'm learning alot so here's my question if I install a 2 in lift to run 275/55r20s streets how much will it effect the mags if any I have stock with 245/75r16s now avg 21 with the 4.0

 

So many of you posters talk about bigger tires with lifts. Did any of you regear your differentials? It doesn’t sound like you did because it’s not a cheap mod.

In my first Toyota 4x4 I went with larger than stock tires but I never thought of doing the essential regear to restore most of the stock performance.

I know there are plenty of people who don’t think it’s needed, but I’m not in agreement with them. Toyota engineers much more knowledgeable than I am (engineers) designed these trucks a specific way for specific reasons.

 

When a couple of you say a "2-inch lift" did you lift just the front two inches?
