I have a 2004 FX4 with 35" tires now and planning on 37/38" in the near future but want to regear now. My question is this, what kind on MPG/RPM@70 are people out there getting with 4.56 and 4.88 gears and is there anyone out there with 35" and 4.88's????

 

MPG with 37's....whats the point ???

 

No one has 4.88's and 35" tires?

 

What are you getting now with your 35s and 3.73 gears?

Nice Truck.

The point is just to know, if I can't get 10mpg highway then I'm sticking with the 4.56s that everyone else is running but I think 4.88s would be more fun and make a better tow did when I load up my mustang.

I have 35's and 3.73s right now. Changing them out next weekend though for 4.56 or 4.88s
