As grayfort pointed out in his first reply to this thread, you need to first accurately figure out what kind of mileage you are getting. The best way to do this is to fill the tank and reset your trip meter. The next time you fill the tank, record the # of gallons pumped into the tank & the mileage. Miles/gallons will give you an accurate measure of the efficiency of your vehicle. Repeat that over a few tanks of fuel and then let us know the mileage. From there, we can tell you if it is to be expected or if you have something that is eating away at it. 14-16mpg is about average for these trucks.

The type of tire, not the size, can make a big difference in your fuel mileage. From the photos I've seen here and on my own vehicle which I just bought a couple months ago, I've noticed that most have off road tread. This is great if you do a lot of off roading but if you're looking for better fuel economy then you'd be better off putting a set of all season radials on your ride. Off road tires not only require more power to get them to roll, they wear down much quicker when only used on paved roads. Another thing to consider if you have a 4WD is even if you don't have the 4X4 engaged, you are still expending power to turn the gears in the transfer case, something 2WD don't have to worry about. There are several other factors to consider too. Such things as the type of suspension you have, body aerodynamics, driving habit, ect.. I have never heard 1 person with a 4WD say they bought it because it gets great gas mileage. More often than not, they bought it as a toy.
My '10 Avalanche LT gets great mileage, 1100kms highway on a tank! vs. 450kms in my Blazer, yes smaller tank, 112L in the Ava.

Your '10 Avalanche probably has cylinder deactivation too which drops down to 4 cylinders while cruising. It's an apples to oranges comparison.

My wife was getting just over 300 kms on her tank before I replaced almost the entire front end parts.
Now she gets 450 kms per tank. The front end was pretty worn out but until I got underneath and took a look I was also stumped on why my 2000 Jimmy was getting 450-500 kms, and her 1999 Jimmy was only getting 300.
