What MPG can I expect with my 31s
My mileage is crappy now that I have 31s. I'm getting like 11-13 MPG. I remember doing long trips w/ my stock tires a year ago and occasionally getting 21 MPG on the highway. Am I running poorly, or is this to be expected? I've done a lot of mods lately, so many things may have affected the mileage.
I'm driving a Weber-ized 1988 258 w/ 200,000 miles.
'88 YJ 4.2L, 32/36 Weber, HEI, 2.5" spring lift, 31" BFG ATs.
