Frist off I dont know if this is the right place for my question, if not im sorry. Here it goes, I want to get the bgf all terraine k/o which will be under the RE 6130 that is waiting to go on. One of the things I would like to know is how much of a differance in gas mileage will I be getting. Im currently at about 16 to 17 city and highway. I was thinking about going with 31x10.5r15 but now im thinking more along the lines of 32x11.5r15 or 33x.10.5r15. What might my MPG be if I went twith the 32's or 33's? I have a 93 XJ 4.0I6 and its a 5 spd. Im not sure what gearing I have(might anyone know?)with no engine mods yet, but it will be getting a new rustys air tube K&N fileter and flowmaster exhaust and a rustys throtle body spacer pretty soon. thanks for the help and Id like to know what you guys and girls are getting if your running 31-33's thanks again tim
