Any one know and one selling a set of decent 30x9.50s?

 

Yea those mallcrawler guys with tiny jeeps.. Haha just messin

 

Ouch.

 

lol nice one. Im down grading cuz I keep scrubbing my tires on the pinch seam in the front fender wells and I need to pick up a few mpgs lol

 

If that's all I have your solution..
#1- cut fenders with saw zaw (solves scrubbing)
#2- buy a hypertech or bulldog program (solves MPG)

 

Cant use a programmer on a renix

 

31's aren't the problem.
Less skinny pedal, or realize you drive a Jeep not a civic.

 

lol I barely touch the skinney pedal and I realize its a Jeep not a Civic but I get like 8mpg and it sucks a$$

 

Then you need to work on that engine.

 

Wow I think you have bigger issues than tires with that mpg. On my truck with a 360v8 and 39.5" tires I'm getting 9mpg (using hypertech max energy that is). So running a inline6 with 31" tires you should be doing at least 12mpg I would imagine

 

8mpg, if that is all you are really getting you got something wrong. I will have to tell one of my friends. He has a 93 xj with 32s on it getting 13mpg and thinks his gets bad mpgs. I got 31s on my Grand and get 16mpg. Do you do a lot of city driving? That is the only way I would think your mpgs are that low.

 

I'm getting 12 with 35s right now...

 

Then he should be getting 13mpg lol.

But yeah sounds like you got an exhaust leak maybe a he's gasket going, something. Shouldn't be getting 8mpg with 31" and. I6

 

Yeah I barely noticed a difference in gas mileage when I went to 31s.

 

Ya I drive from brittney woods area to north chase bussiness park and to walmart once a week for gas. I think my O2 sensor is going bad but IK my map sensor keeps going bad for some reason. Iv put 3 or 4 map sensors in it and noticed a bit of a mpg gain every time I change it then my mpgs drop again :/. I saw 19mpg for like 2 weeks before I started getting 8mpg. The motor was punched 30 over 3angle valve job port polished and I think thats it. The prior owner did all this work. I have upgraded the Injectors new air filter plugs wires dist. cap and rotor button. Other then that the jeep is stock I have noticed that the jeep tends to run rich at times and havent figured the cause of this out yet but oh well.
