Too cool not to share!
No written directions, but the picture is pretty self-explanatory. I have two old tractor tires I can get my hands on!
I think I would rather use the heavier black pond liner stuff than just plain plastic sheeting though. I also think you could saw off a section of a big #2 plastic drum for this, if you can't find a big tire. The top edge on those are smooth.
