Folks, I've been riding for almost 30 years and wrenching for 26. Went to MMI, worked at dealerships for 15+ years. I've changed thousands of tires over the years - on the floor, on a Coates 220, on the regular pneumatic tire machine. In that time I've never had a serious injury while wrenching - until last night, that is... I was changing a rear tire on a Seca 2 (fix-up project to flip for more $$ in K7 warchest), had the wheel off on a stand, rock hard old Cheng Shin tire... got the bead broke in my bench vise. Popped a tire iron in, started prying with the 2nd one. It slipped, 1st iron flew out and hit me in the face. I ended up needing 5 stitches, and cracked a tooth!
The freaky part is if the iron had hit 2 inches higher up I would no longer have an eye.
I guess the moral of the story is just a reminder to be careful!!!
