It happens to everyone who rides a bike—you’re rolling along and all of a sudden it becomes hard to pedal, maybe you hear the hissing of air leaving your tires, maybe it’s the loud boom of a blowout. Or you go to get on your bike and discover that a tire is flat because somehow the air leaked out during the night. The result ranges from an inconvenience or it could be dangerous but it is always trouble. Not all flat tires can be prevented but there are simple steps you can take to reduce the likelihood.
