Tire Size question

[Ridgerunner]

I am Curently Running 35's on my J10 with 4.56's and a 4l60e 4sp auto trans.
Since I will not be Wheeling this hard any more I am thinking about dropping tire size to 33's and using some more hwy friendly AT's.
4l60e Ratio
1st-3.06:1
2nd-1.63:1
3rd-1.00:1
4th-.70:1
Im sure it will help my braking, but I am not sure if it will hurt or help my fuel milage. The truck with the 35's gets around 13.5-14.0 MPG but is kinda a dog on the hills so the 33's would help. What do you guys think would it be worth the swap?

I think 33's would be fine with that set up...

and I am willing to bet you would get better gas mileage.. well as long as you keep your foot out of it

Yeah, probably another 1-2 mpg or so.

Yeah, probably another 1-2 mpg or so.

that would be nice.

check out this site. I'm not sure how accurate the calculators are, but they have them for gear ratio's & tire size...
