Default To those with 4.56 or 4.10 gears

Please give me your city/highway mpg's with these gears. I am curious how much difference there are in the two.

The answers should include tire size as well as whether or not the speedometer/odometer has been corrected.

I went from 3.55 to 4.56. I drive about a 50/50 mix of city/highway. I didn't really see much change, I got 11-14 mpg with the 3.55's and pretty much the same with the 4.56's

Can you go 70 on the highway or are your rpms to high that is why I went with 4.10.

you get better city mileage then highway mileage, lower gears like 4.10 or 4.56 are best for towing or light to light
