I met a Canadian guy one day back in the 90's when I was working Customs. I wasn't going to pop the question but he beat me to it and said "I know you are wondering what happened to me right"? He looked like his entire face neck and who knows what else lower was put in a fire and grafted back like a puzzle. He said he got hit by a flying tire in a shop that they told him later put him up into the roof rafters or bounced him off the ceiling I forget which. I said **** what was it a tractor trailer tire? "Nope it was a regular passenger car tire with one of those lock on inflation clips on the air line. Thats why i would just as soon sit down next to a tire and hold the chuck and never bothered with any clip ons. Too easy to get distracted and forget it's on there.
Wasn't it just a couple years ago they come out with something regarding those cheesy plastic cart wheels you can buy for $5 wheel and all? One of them popped the rim and tossed a shard of plastic into a guy and either killed him or did severe damage. Another reason why I like to toss on a grinding shield when doing that sort of stuff in iffy circumstances, grinding too. People think about their eyes and forget just how soft your throat area is. I always try to nod my head down even with that when grinding and such just in case.
