Well you are using 35's. Also, your odometer isn't correct either because of the tries. So you have actually driven farther than the odometer says.

I'm running 4.10s with a 6 speed and drive pretty lightly. Other than GPS, how could I calculate my total miles then? I shouldn't be getting this bad of gas mileage. Even before the tires is was ridiculously bad. Again, I'm just praying something kicks in.

Default So its not just me getting around 13 mpg?

For a full tank of gas, I average 13-14 mpg. I only have 1300 miles on it so I am hoping that it improves

Well i don't know how to calculate the actaul mileage, but i don't see how your gas mileage was that bad before tires. On my rubicon i was getting 17-19 and that is a 70/30 city/highway. That is about par with most suv and trucks out there.

If your Jeep came with 32" tires on 17" wheels (255/75-17), and you're now running 35" tires on 17" wheels (325/70-17), your speedometer is 8.9% slow... so multiply your odometer-observed mileage by 1.089 to obtain your actual mileage.

I agree with JohnL. Individually neither my AEM or Gibson exhaust was much to scream about but together there is a considerable power increase and 1.5 mpg increase.

I found the same increases when I switched to 89 octane. I have not been able to duplicate the results with 87 octane. THIS IS IN NO WAY A CHALLENGE TO REINSTATE THE "OCTANE WAR" debate of a month or 2 ago. I am simply throwing in my 2 cents.

Banks has some nice looking shorty headers out now. Haven't seen the price yet
