A while back, I answered a CL ad for 2 free tires (24x12.00-12's). The guy met me at Atwoods and I brought them home. One thing I noticed right off was about 8" of wire sticking out of one tire. Today I got them out to patch over the plugs and took the wire out. This is how much was inside the tire!
I bring this up as I was a victim of a flying piece of wire back in the 70's. Push mower i was using caught a piece of old wire and it bounced off a metal building and lodged in my arm between the bones. It was nearly 3" long and took about 4 hrs. in the ER for them to finally get it out! They kept sending me back for more x-rays as they couldn't find it!
This piece of wire had to be 12"-15" long flying through the air and yet stuck this much through a tire. Would not be good for a body!
