Having a flat bicycle tire can leave you stranded, but it’s simple to replace the tire yourself. Usually, this just means replacing the tube inside the tire. However, you may need a new tire if it’s very damaged or worn. Before you replace the tire, you’ll need to take it off. Then, replace the tube and tire, if necessary. Finally, put the tire back onto the wheel.

A fat bike is a type of mountain bike that has fatter tires designed to grip soft, unstable terrain, such as snow and sand. Just like regular mountain bikes, fat bikes can end up with a flat tire, in which case you’ll have to remove the tire and replace the inner tube. You might also want to change the tires one day when the tread wears out or to swap out the style of tread you ride
