First, a lot of people freak out when they first figure their MPG's after adding taller tires. But they fail to realize that their figures are off if they didn't reprogram the computer so the speedometer/odometer is accurate. Also, at any given size an all terrian tire will usually give slightly better gas milage than a mud terrian. Also, tire/wheel weight and tread width will also affect milage/performance. A 325/60-18 is basically a 33x13.00 tire. A slightly narrower 33 inch tire (like a 285/65-18 or 305/60-18) will help your milage a little.
I love my 2500, I traded my 2011 1500 in because I did not like the bed length and I tow a 4 door jeep. I am even thinking of going down to a 285/60/18 which is a 31.5 tire. I am running the Nitto terra grapler.
