What is your MPG's

I am looking at going from 32's to 31's to improve gas mileage. I currently get 13.5 MPG's.

And i know i didn't buy this thing to get great gas mileage, but more than 13.5 would be great

Thanks

 

About 18hway and 15 around town. 265/70R16's they measure 30.6/10.4

 

I have 31 BFG A/T and i got about 19 or so last time i checked.

 

about 18

 

I ran 33x12.5's on stock gears and still got 13.5ish MPG. Maybe you need a tune-up?

 

my 89 5spd get 18-19 mixed and 23-25 highway. and that's driving easy. as soon as i start getting after it, mileage drops considerably. stupid 4.0 get thirsty if i'm not careful.

How will 32's improve MPG?

 

think you read it backwards bro

 

Yeah 18 19 on the highway and 14 15 in town is about the average

 

Wow.. it's been awhile with the XJ... i didnt realize the 4Liter was so thirsty..

5.9 gets about 12c-15.5H with 32"s

 

7.1 mpg with my 31s and 3.55 gears ,4.0,auto in a 96 XJ.14.89 with factory tires.

 

I get 11 city 14 highway, with 31 bfg a/t's and 3.07 gears. Was getting 17 avg with p235's.

 

Thanks all for the replies,
Yeah i just replaced the head, cleaned everything, and gave it a tune up pretty recently. It is looking like my next set of tires will be 31's. If the adverage consensus i am seeing is a 3-5 increase in mpg.

Anyone need 32's? lol

 

x2... this seems exact for mine too

i need 32's!!! what do ya got

 

15 city/ 20 hwy or so on 31's with 3.55 gears. If I drive like a grandpa I can get close to 17 city and about 21 hwy.
