fuel economy list gears and tire size
 
Good place to list fuel economy to gear and tire sizes...

What's the average fuel economy for a 3.8 manual running 33's and 35's with 4.88 gearing?

And if anyone else wants to list there gears tyre sizes and fuel economy that would be great

Not sure about those but I'm running 4.10s with 285/75/17 Toyo M/Ts. Im hitting about 15 in town and 19 highway. Give or take and MPG or two.

3.8 auto, (sorry, not manual) but 35s, amor, 19 and I play with the skinny pedal hard, 3.73 gears. I get 17 when I grandma it. I was getting 15 this morning but there was 40mph winds, so that killed it.

2008 Unlimited, 3.8L auto, 3.73, Superchips, heavy Pitbull tires true 35", OD Off most of the time average 17-18mpg. With 35" Duratracs the average was 18-19mpg.

Tire weight can play a major roll in mpg.
