I recently have put a 2.5" pro comp lift with 33" BFgoodrich km2 mud terrain tires on my 2010 Wrangler 2dr, and front/rear best top metal bumpers (rear w/ tire carrier) and my mileage has dropped from around 21 on the highway 14-15 in town, stock, to now around 12-13 all around at BEST. I know Jeep's aren't Pruis's but I mean that's just horrible. Any suggestions on why the drastic drop or how to improve it?

 

Alot of us run the superchips flashpaq! You can find it at northridge4x4.com!

 

not bad for a rolling brick.wait till ya go to 35's or bigger.

 

So true too! Lol

 

that seems a bit low. I have a 3.5 inch lift with 33s and a front bumper/ rear tire carrier. I get about 17-18mpg on the hwy
Did you re-callibrate your speedometer/ odometer? If you havent the larger tires will throw off your mpgs.

 

I have a JKU with 3.73's, AT and 33 inch BFG AT KO's. My wife will average right at 16 mpg but it drops into the 15 range when I drive. If I hook my 6x10 utility trailor and two dirt bikes behind it the mpg's drop in the 11 mpg range (with overdrive switched off).

 

I have 34s with 4.88s on a 4 inch lift and i get 13 around town and 11 on highway. Urs sounds bout rt

 

i still have a set of rubicon take offs, 2.5" lift, front bumper and some rocker armor, i got 11 mpg last time in town. only ideas are either i need an alignment, or i should get around to getting my evap canister fixed

 

I have 4.88s and 38s with a 6spd and get 13 highway and town. Its pretty sad cuz my wifes 2012 hemi durango gets 24 hwy

 

I was also getting 21 stock
