I was just cutting a round cheese board out of 1” black walnut on my delta 14” bandsaw and bang - a piece of my urethane tire shot out the back of my saw. No injuries but a big surprise to see the upper tire totally destroyed. It never occurred to me to replace the tires periodically. I had replaced the original years ago just because Ittura design was offering these snazzy looking orange ones. On examination the tire was extremely brittle. See attachment.
