if the tire came off, it indicates that it has reeached the end of ots useful life. your best bet is to get a new tire from the manufacturer of the bandsaw. second choice is to order one from online. there are ads for bandsawa tires on ebay. the new tire will seem to be to small for the wheel, but if you soake it in warm water for a few minutes and lube the wqheel with liquid dishwashing soap, it is easier to get it on the wheel.
