Difference Between Tubeless and Tube type Tyres
Tubeless

The inner tube is integral within the tyre, known as Innerliner. The valve is permanently fixed to the rim. THE ASSEMBLY IS AIRTIGHT.

In case of a puncture, loss of air is very slow, since air can escape only through the narrow gap made by the penetration of a nail.
Tube type
Components: Tyre, Tube with Valve and Rim.

Instant air leakage after getting punctured. The air under pressure finds a way between the tube, tyre and through the rim hole.
