A huge percentage of tires that go flat don't blow suddenly, they gradually leak air out; plus if you don't know how to check out the condition of a used tire then you probably haven't been riding very long which goes back to your fear of busting out teeth in a blowout which would be due to your lack of experience to control a bike.
