My Avalanche has 33x12.50R20LT currently. Would I be able to place 33x12.50R15 108R All-Terrain Tire on the same rims? I'm not sure what the rim size is. I'm not currently around my truck.....Uncle Sam has me in training.

Nope. The "R" tells what rim size each tire is working with. Sounds like you've got 20's and you're looking at 15's. Just a heads up, the avalanche may have a minimum wheel size to clear the brakes. I don't recall seeing them come with anything less than a 17" wheel.

Lol, yeah, the red is rim diameter / how big the hole in the middle of the tire is. Tires with a 15" hole in the middle need rims with a 15" diameter. Tires with a 20" hole need rims with a 20" diameter.
