I have seen several Tundras with those wheels.
They are, without a doubt, the nicest wheels I could imagine putting on a Tundra. Pictures do NOT do the wheels justice. When you see them in person you will be immediately impressed with the finish and workmanship of the wheels. You can get the wheels for about $590 or so from the internet TRD dealer and select your own tires and save a grip of $$.
I'll say it again, they are simply the BEST looking wheel I have ever seen on a dealership lot, PERIOD.
People spend double that per wheel for some 22's that are half as high quality as those wheels are.
Here's a link to the lowest price I have seen so far:
