My 2002 with the 3.0, Steptronic and OEM trailer hitch scales at 4472 pounds. I'd say his wheel size has more to do with his lower mileage than anything, especially if it's primarily city with a lot of starts and stops. The tire/wheel combination may weigh less than the OEMs, but the moment of inertia is higher with the larger diameter wheels and actually takes more energy to accelerate. Also, I see it's 6 degrees centigrade in Littledean, UK right now and we all know that colder weather eats up the fuel too.
