Duratracs & MPG???

Hey guys. Its almost time to drop the hammer on some new tires and I've really been digging the Duratracs. They are perfect for me but I've one concern....gas mileage.

I commute at least 70 miles a day and can't really afford to loose any more mpg's. Right now I've got mini-van style highway tires on there and I'm wondering if my gas mileage will hit the floor when I get the Duratracs.

Has anyone noticed thier gas mileage going down (or up) after installing the Duratracs? What tires did you have on there before? Also....how many miles are you guys getting out of these tires? Thanks!

Larger and/or more aggressive tires will lower your MPG's slightly. Anything that adds more weight (bigger tires and rims), more wind resistance (wider tires), or more rolling resistance (aggressive tires) will have an effect on your MPG's.

You're correct, but I guess I left out that detail. The 31x10.5 duratracs will be replacing the same size tire. The duratracs only weight 2 more pounds each than what is on there currently.

I guess I should have asked....for those of you who have replaced the same size tire with Duratracs......did you lose any mpg's?

im about to be switching from Firestone Destination A/T 245/65/17 to a set of Nitto Terra Grapplers 265/70/17 with a 2" RC lift. Anyone have any idea how much worse my 3.7 WK MPG is going to get. I get about 18.5 right now, which isn't that bad and the destination A/T's are about half tread.

also, anyone with pics of these tires on their WK post em up. I'd like to see them.

You're gonna' take a hit. The Destination AT is one of the most fuel efficient AT tires on the market (and lowest road noise too).

I went from stock 225s and alloys on a 96 XJ to a 2" Lift and 31" duratracs on steelies.

The Duratracs on steelies were a LOT heavier. MPG went down about 1.5-2.

Shouldn't be too bad if you're already running 31's. I went from 31x10.50 Cooper STT's on 15x8 steelies to 31x10.50 Duras on 15x7 alloys, and I gained mpg.

Just fon't go with steel wheels, those'll kill your mileage.

I went from 31" Mickey Thompson MTXs basically there old AT tire, to 33" Durtracs and lost about 1mpg. Anytime you go up a size in tire you will lose MPG. A more aggressive tread in the same size you will lose some but it probably won't be noticeable.
