    Hey guys, I've been running 4.56 gears with 33" tires for a long time. The power has been great, MPG not so much. I'm looking to upgrade to 35" tires and have always wondered if going to 35"s would bump my MPG since the tire to gear ratio is much closer to stock. Anyone know the answer?

    I thought it would be better MPG with the gears you have now. Thats quite odd.

    Higher RPMs on freeway = bad MPGs

    Yeah from what I was told 315s and 4.56s is near stock set-up

    You're not going to gain anything. You'll go up in tire size but you'll also go up in rotational mass. Your engine will spin at a lower rpm but it'll work harder trying to rotate the tires.

    I went from 33's with 4.56 to 35's. Fuel mileage has not changed any. It hasn't gotten worse and hasn't gotten better. If you do gain anything it'll be .5 miles. Which doesn't justify getting new tires just for better gas mileage.

    is it bad to run 31"x15 or 16"x265 on 4.56 gears on 2006 2.7 5lug for a daily driver? or stick with 4.10
