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.

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.
