I use old tires to hold down tarps on my manure pile. They fill up with water, can't get it out. I tried drilling holes in the tire, the rubber just closes up. Same thing when I used a .22 to shoot a hole. Any ideas on how to make a hole big enough that won't clog up, like at least 1/4" in diameter? I was thinking maybe heat up something with a torch and burn a hole, not sure if the steel belting will stop that.
