What is your gas Milage with 33's or 35's? Does it make a big difference between the two tire sizes?

 

I have an automatic with 35’s and I am running 4.88 gears and I am getting 14.5-15 MPG.

 

I have a 08' Manual Rubicon with 35's, was getting around 17-18 MPG, but after adding front and rear bumpers and a winch I'm now around 15/16MPG..

 

08 JKU Rubi, auto, 4:10, KM2 35's, front & rear bumpers and winch.

approx 12mpg city

 

When I ran 35" BFG KM2's, 4.10 gears, Flashpaq tuned to 91 octane, auto trans, I had an average of 15 mpg city, 17 mpg hwy.

 

I have an automatic 07 with 35's and 5:13 gears, rock hard rear bumper with all the extras, stock front bumper still and the milage is a crummy 15 or so...

I installed a K&N ram air filter got a lot of intake noise and lost 1 mpg... go figure??

 

What kind of front bumper? a stubby or a full wind kite?

 

I have 35" Nitto Trail Grapplers. Just calculated my gas mileage today after being able to run highway speeds with my 4.88's. getting 14.45 at 65-70 with the jeep full of stuff... probably weighs more than a full passenger load.
253 miles at 17.5 gallons
4 dr 6 speed btw.

 

auto 35s with 4.88s. Usual get about 12-13 mpg. pretty hilly in my area though.

 

auto with 4.10, I have a 2.5 procomp lift with leveling. heavy front bumper with winch..

procomp 33's and a hard top.

Also K and N, MBRP exhaust, superchips tow tune and i get about 14 in the city and 17-19 on the highway(when theres hills more like 17 when its flat more like 19)

Stock I got about 21 on the highway and 15-16 in the city so i lost alittle.
