Are these the wheels?
Edit: You may have to copy and paste url to work, when I click it goes to page not found on Ebay.com
If you click Full Description it says it's a "Hybrid" wheel, 2.6" outer and 3.2 inner for knuckle clearance, and that it "fits" Clod and USA1 tires.

I guess they expect you to cut the inner tire bead? Beats me, other than TLT tires and newer short course/Slash I haven't seen any such tires with smaller outer bead.
