i just bought my first jeep 2 months ago and love it. what i was wondering is what kind of mpg are ppl getting? i have a 4.o w/ a 5 speed, no lift. and im barely getting 10 mpg. also what is a good 31x10.5 tire for a jeep?  

really? i have yj with a 4.0l and a 5 speed with 30" tires and 3" bodylift, i would guess mine gets about 16mpg. i spend about the same at the pump as i did with a 4.7l quadcab dakota  

Mine is a 89 4.2 with a crappy engine, 5 speed, 34" TSL's, 5.5" lift and I am getting 13 to 14.

My pops has the same setup. I changed his plugs and wires and he went from 14 to 18  

my 03 rubi gets around 10, I drive around on 34" trXus with only 12-15 pounds of air(going to and from the coast or china hat with properly inflated tires it runs 12-14 @65MPH) and I live in mountainous area, I rarely drive on the hwy more than 15 miles round trip to the gas station. stock I was getting about 16 with 4:10's and the 31's.  

i have a 95 yj with the 4.0 high output and 5 speed, i average 17 mpg. 30" coopers  

i have a 96 xj, with a 4.0 high output and run a 3in lift with 31-10.50's and average around 13 mpg....i recomend BFG all-terains
