What kind of DIY projects can I do with Wire wheels?

Oh, that's cool! You could make a large grouping on a wall and it might be stunning. Depending on how you decorate, you might paint them in coordinating colors or leave them as is. Another idea is to adhere them to different sized, conduit or other pipe material and group them in your yeard. Probably in groups of 3 or 5...not an even number. Hope this helps.

Maybe as a hanging pot rack, if hung from a kitchen ceiling?

Some ideas:

Wow, so many ideas for wire wheels!!! Want to share a few?

Depending on the size, a hanging mobile would be interesting.

Use some as a base for a hall table/credenza. If they are rustic use reclaimed wood for the base and top. If they are shiny and artsy looking use glass on top and the bottom rails out of PVC spray painted to coordinate with the wheels
