I had put screws through some old worn down tires before to get some traction. I wasn't on ice, just grass... It would rip out and throw pieces of grass into the air. Very cool looking. But I was scared as hell to ever give it throttle when it was near me.... I just kept thinking " one of those screws will fly out and hit me in the eye"
i did that to a set of my old tires from the inside i took 1/4 inch self tappers and it cool in the grass but once u get goin it gets really squirly its kinda fun, if u have old tires y not try it, they do make chains for them also
Yes they were screwed in from the inside.... I just couldn't help thinking that one could possibly fly out while the tires were balloning... Am I wrong here:\
