If it helps you to know, the one time I decided to go all-out in maximizing my Subaru's MPG with driving style and technique alone, I had the A/T-S in that size, 215/60R17 on along with the "weighs a ton" emergency kit in my back.
To my own surprise, I managed 40.2 MPG on that 120 mile drive home despite the extra weight of the kit, chassis bracing, skid plates, and all-terrain tires. This is NOT a typical result, but still surprising to me considering the factors working against me at the time.
But, bear in mind the all-terrain tires present a slight MPG loss, minor with the A/T-s and its successor, the G015. The more-aggressive all-terrains are likely to see a more significant penalty such as the General Grabber AT2 and BFGoodrich All-Terrain KO2.
