the 4.5" won't really effect your mileage, tire size will though. I'm on 31's and get about 17-18 mpg average.

^same. I see these posts all the time and wonder why are you worried about mpg when you own a cherokee. Dont meen to be an ***, it just seems like if you own and modify one of this things you should expect ****ty mpg.

I do expect crappy mileage but not 13.5 mpg. I think mine can be improved to atleast 16, 18-19 if i go from 32's to 31's

1 less inch of tire is not going to make 4 or 5 mpg difference...
