I drilled 3, 1 inch holes in the top sidewall of each tire about 3 inches below the treads. I created a tire pyramid last fall using the biggest tires I had. It stands about 7 feet tall using 4 tires as the base, 3 tires in the middle, and 1 on top. Drilled holes in all of them and the entire structure is now underwater.

A local recycling center picked up the remaining 150 tons of tires I had laying around. Ten years ago I would have had to pay a small fortune to have them taken away. This outfit must be recycling them in some way. Either way I'll take it...
