When mine was stock I was getting low to mid 20s city and mid to upper 20s highway. With my lift and 31" tires I get about 22 to 24 highway after I calculate for tire size. 90% of my driving is highway so I don't have a good indicator of city milage. If you are going to use your Kia for hunting I have a 2 1/2" spacer lift and Dave scott has a 4" spring lift. With mine you can run 30" tires and with
Dave's 31s or 32s with a body lift.
