Another option is the fairly new tire shades made by Magne Shade
They cover just the tire and have a very "clean" look, many people don't even notice I have them installed until I point them out! They're easy to install if you do so before dumping the airbags (provides more room to reach around in the wheel well). There's a bit of a trick to folding them for storage, but once you learn it they are super-compact and come with a nice storage bag.
I have had a full set of their magnetic window shades for years and love them. They're a small company with friendly and responsive folks.
