Interesting. I am surprised they destroyed the casting for the WA-0550 wheels. There are so many 100's, 200's, Sequoia's, and Tundra's out there that could use those wheels.
It could be possible to get 20 people together who would buy five wheels to hit the 100 wheels if they agree to that...
No worries! They are out of stock everywhere and Hutchinson isn't making them any more. So the only chance I see in getting a set is someone selling them here or on another Toyota off road forum...maybe one of the Tundra forums. I kick myself every time I think about wheels for my 100's.
