A tubeless wheel is very similar to a traditional wheel; except that it has no tube inside. Air in the wheels retained between the rims and wheels itself, with the use of an airtight seal. Tubeless wheel can be filled with liquid sealants. If a sharp object puts a hole in tubeless wheels, the liquid sealant immediately oozes out and dries up; thus sealing the hole. This enables you to travel longer without having to worry about a puncture.
