Default Very Specific mileage question

I'm looking for 3 or 4 mileage numbers from the same person as driveing style and conditions have everything to do with mileage numbers.
4.10s and stock tires.
35" tires on still with 4.10s.
35" tires with 4.88s
Stock tires with 4.88s

Also if you can put down your transmition type and aprox rpm at 60mph.

I'm trying to figure out if I should regear or not as I do a huge amount of street driving and mileage changes are a factor for me.

With 35s you will get 14-17 no matter that gearing/chipping/exaust/intake mods you do. You have a jeep not a prius.
As well the numbers you request are impossible to determine becasue everones driving styles are diffrent.
If you get 35's your milage will go down. No matter what gearing you have your mpg might change by 1 in which case it is not worth regearing if you have 4:10's

my jeep w/ 3:21 and 34's has seen between 15-19 mpg depending on how I drive it.

MT 35's (So actually 33.75" tall). 2800 RPM's at 70 (I will have to look at what 60 is) 6 Speed, averaging 14.5MPG, 50/50 City/Hwy, and I drive moderately aggressive.

With 4.10's and 32's I got roughly 18 onroad/12 offroad.
4.10's and 35's 16-17 onroad/8 offroad
6 speed/ 5th gear about 2000 RPM 6th is pretty heartless

Far too many variables for the numbers to be meaningful. Here are 66 pages of MPG data. Go nuts...

Or look through any/all of the other mpg threads to learn the same thing.
