Gas mileage?

What kind of mileage are you getting? I'm at 15.25 to 15.75, I check every time I fill up. Stock 4.0, auto trans, 31" Bridgestone Dueler Revo's
89,000 miles. Put new plugs and air filter in and cleaned the throttle body. Is this average/ normal. I drive it to and from work mostly highway 15 miles one way and run around town.

Really? My '03 consistently pulls 18 hwy mpg. 33 mile one way, about 2-3 non-hwy, and I cruise at 70. 5sp if that makes any difference, and I am almost 85K. I do have the 30x9.5's though. Do the 31's make that much of a difference?

Manual vehicles for all vehicles get on average 2mpg over auto trans.

If I went from 31 BFG AT tires to 31 BFG KM2 or Baja MTZ tires, would my gas mileage take a big dive? Thanks for any information.

The more you build it up the worse your fuel economy gets. My stock Wrangler was getting 20.8 mpg... switch to bigger tires (32) mpg dropped to 17.8... removed stock bumper & put on big heavy bumper & mpg dropped again to 16.8. Guess after I put on heavy winch on the bumper I'll be getting 15mpg!

Dang?! I've got a 2000 TJ stock, BFG A/T KOs 30x9.50x15 4.0L 3spd auto, 3.73 gears. I use the medium grade gas, I get a steady 17mpg city- 19mpg hwy (I try to stay close to 67mph) I had planned on going up to 31s with either KM2s, or Maxxis Big Horns. but if I'm gonna loose 5 to 6 mpg's. I'll just stick with the 30's.

Another thought/question, when going up in tire size it throws the odometer/speedometer off, probably not much going for 30's to 31's. So if I have my thinking correct your odometer would show less miles traveled than actually traveled( feel free to correct me if I'm wrong) so we may be getting a little better mileage than calculated? Probably not much but maybe a little?

If you're worried about gas mileage you shouldn't be driving a Jeep in the first place, that's kinda like a Ferarri driver complaining his car goes too fast when he hits the gas...

Not worried about the mileage by any means just making sure I'm in the same ball park park with everyone else. My motorhome gets 7mpg! Gas mileage is not the issue.

You are correct. there are calculators available for the numbers, but I personally like to have someone with a stock car drive a route I know I drive often, that is longer and varied. aka with both highway and backroads. then use a gps. look at both the distances. then drive it in your jeep, and then find the percent difference between yours and the average of the gps and friends car (should be close between those two) and then you have how much your off. Im off more than just what my tires are off by a good bit. so this is the method I used to be most accurate.

If you remove all the extra weight in your rig you might see a slight increase. By extra weight I mean back seat, doors, top, etc.

Second thought, I dont think I saw a change at all, but it makes me feel a lot better about owning a Jeep!

Remember also I think most 31 inch tires only measure 30.5 so you won't see much of a difference.
