The April 2011 issue of Four Wheeler magazine has a very good article on how different tires effect gas mileage. Changing from an all season LT tire to a all terrain LT tire reduced gas mileage 10-15 percent, 2.231 MPG. I am sure some of you will find this article very informative.

For the best MPGs on these trucks get the stock P235/75/17 Hankook tires.

These tires are yuck but give better MPGs.The rougher the tread the lower the MPG.

there are other factors involved. AT/MT's are generally heavier than stock type tires as well and the additional weight will also cause a reduction in mileage. Heck, on my last truck I went from a 33" MT to a 32" AT and saw no increase in mpg's...the AT's were just as heavy as the slightly bigger MT's.

The lightest weight P rated tire will give the best mpg and give better braking distances too. That's why they are used as stock tires even though they look like crap, get too many flat's and handle terribly. I'll sacrifice 1 to 2 mpg for the tires I want and suit my need's. Just my 2 cent's!

Since we're on the discussion of tires and MPGs...I'm looking at a 275/65/20 A/T to replace my stock 275/55/20 Pirellis. I'm trying to keep the 275/65s equal to or less than the stock tire weight.

I've read going wider will hurt MPG worse than going taller. Any truth to this? What do you think my MPG hit will be going 2" taller w/same width and same(ish) weight?

yes, wider tires push more air and offer more rolling resistance, not sure how much it would affect it, but it definitely will affect it.
