You might not find too many "super light" alloy wheels for truck/offroad use.

 

Divide the miles driven / the amount of fuel used. That will give you miles per gallon.

 

I do not find it all that bad.....
I just run stock aluminum with 32.3 inch Goodyears unless I am going play....
then I throw on the steel rock crawlers and 32.8 inch Mickey T's...I don't want to gouge up the aluminum MOABs on a rock...
who cares about fuel economy when your are climbing a mountain and having fun?????

I may find an all-terrain that does not weigh too much ........or leave well enough alone until the 36000 mile mark when I don't have to worry about warranty!!!!!!!!!!!!!!!!!

 

ATs dont weigh as much and have less friction moving. That noise isnt just unpleasant, it sucks up some gas. If you care about mileage, that is what you should be using, IMO.

 

one suggestion is to get a CAI and Cat-Back Exhaust... when stock, that upped my MPG to 23.5 on the highway! So when I lifted and put 35"s on, (on 0% gradient) i'm around 19-20mpg (highway)... i can only pull about 14 mpg around town.

 

Why can't they just come out with a diesel that gets like 30MPG. I would be in heaven on that day!

 

They do make a diesel. You just have to move to Australia. This is a thread with pics of the new JK in diesel.

4 cyl... 23 MPG, thats not very impressive. I'm not looking for a pig..ehh maybe i should just stop complaining, get a new jeep, and continue my 12 MPG spree.

 

Unless you use a gps or have your speedo/odometer recalibrated, you cannot compare your pre and post changes.

Bigger tires will cause your odometer to under record your mileage as you will travel further for each wheel turn than stock. The JK speedo/odometer is computer controlled using your gear and tire diameter combination to calculate your speed and distance. These are set at time of manufacture and can be flashed by the dealer for 225 up to 32 inch tires and stock gears (3.21, 3.73. 4.10)

A regear, change in tires and/or lift will greatly effect your mpg.

Accurate before and after compares (tires and/or gears involved) requires that you use a GPS or recalibrate. Anything else is apples and oranges.

 

2.5" bb, stock 17" wheels, 32" BFG MT Rubicon tires, 4.10's on a 6 Speed manual Unlimited X, I get wood when I get 16 mpg. Highway, I get max 18 mpg. In town (downtown stop and go traffic to and from work every day) I'm averaging 16 mgp right now...less in the summer months when it gets hot. This is top up, windows down, and A/C running. Top down lowers mpg considerably. No A/C also ups my mpg. By hand, my mpg has been lowered to 14 on the trails, A/C runnning. Not good, but not horrible. I'd like better, but my Ford Ranger 4 cylinger wasn't much behind it when I traded it in.
