Guess I should consider myself lucky. My lifted 03 3.7L 5-speed Liberty gets 19 to 22 MPG on stock tires. The 22 mpg came during a trip to California over Donner Summit.

 

[JeepJunky33]

cb,
How did you manage that? Did you keep it at 50mph the whole time? I have an 03 KJ Ren. w/o a lift and I only get 19-20 on hwy and 15-17 on city (dep, on how hard I'm driving it)

 

[cb4017]

Actually that was holding around 75mph. Keep in mind it was mostly downhill after crossing the summit. 7,500 feet to near sea level.
The worst combined milage I've gotten so far with my Liberty is 19mpg. Much better than what my Cherokee would get.

 

[JeepJunky33]

Wow then that is awsome...your my hero!!!

Does anyone know what the 16's pressure is supposed to be, meaning what the factory recommends, not the reading on the side of the tire.

I just went and looked. 16's, on the door is says 33 PSI cold. So 39 hot, may be a few over. Well, if they blow and she rolls, then we'll know 39 hot is too high. (Cheers)

They look okay.

Actually Tim, earlier this Spring when it started to get hot, I noticed a few tires got to 41. I did get concerned... ssst.gif But now they aren't over 39.

 

[2003KJ]

well max is what, 44? I don't think it will hurt anything

 

[grogiefrog]

Yes, 44 at max. It's just that Explorer deal with the roll overs that I think about from time to time. I recall Ford saying, "if it says 34, 34 it should be!" I know... legal bs... for the lawyers.

Actually i believe the ford deal was Firestone recommended something like 33 or 35 and Ford recommended 28 (yikes!) so they were inflated to 28. IIRC the sidewalls collapsed from premature wear and thats what caused the tires to blow up.

I guess I can see that with keeping them too low. It is amazing that vehicles in general work as well as they do and don't "explode" on us more with the thousands and thousands of parts.

no kiddin.

Hey Aaron, why don't you get AIM so we don't keep playing message tag like this....LOL.

 

[fujitsubo]

Does anyone here have a proper set or formula to calculate fuel consumption properly? I know depending on how one calculates, this can vary in degrees of math.

Fill the tank, annotate odometer reading, drive to nearly empty, annotate milage, subtract odmeter readings, fill tank, divide miles travelled by gallons of gas.

 

[2003KJ]

I just reset my trip meter every time i fill up, remembering to write down whatever number is on the trip meter on my little receipt then divide the miles traveled by the gallons purchased. For example, 234 miles on 10 gallons of gas (ha ha ha) = 234/10 = 23.4mpg

 

[big steve]

i average about 17 city highway mix went down to toledo ohio (about 200 round trip) with air on all the way and a full load and ave 19.8 mpg go figure (Aeh) oh yea 2002 lib 56,000
