Tubeless tire

If a tubeless tire gets a small puncture, air escapes only through the hole, leading to a gentle deflation.

However, the "bursting like a balloon" scenario is highly unlikely due to fact that the inner tube is inside of the tire and will deflate at a rate proportional to the puncture hole size.

In antique automobiles, made before the mid 1950s, the rims are not designed for tubeless tires, and an inner tube is required to prevent slow leaks at the bead.

In addition, mending a tubeless tire is easier than a traditional one—a simple liquid sealant poured over the puncture is often enough to patch it.

Furthermore, the higher air pressure inside a tubeless tire provides more stability and comfort while driving.

Lastly, the lack of a tube also boosts fuel efficiency due to reduced tire friction.

Some feature a larger internal diameter than usual Presta valves to prevent clogging and to accommodate more air flow during installation.
