I just saw a video on yt where a guy claims his cycle has tubeless tyres and then goes on to fix its puncture by removing the tube from tyre. so is tubeless a misnomer? how do they remain inflated?

A tubeless tyre has nothing other than the tyre and the wheel and they seal together to create an airtight space.

A tubed tyre has a separate inner tube that holds the air and keeps the tyre inflated.

A very good example is a pushbike wheel with spokes, because it has loads of holes in the rim it **needs** an innertube to hold in the air and to keep inflated.

A Car wheel without spokes has NO holes through it so it can create a chamber with the tire to hold the air in.
