Which type of tires retains pressure better and shows a slower loss of air in the event of a puncture?

Question

DentroTest · Accepted Answer

Tubeless tires do not use a separate air chamber inside them; instead, the outer tire itself, in direct airtight contact with the rim, performs that function thanks to a special inner lining. When a tubeless tire suffers a puncture (for example, from a nail), the object usually stays lodged and the air loss is very slow and gradual, which drastically reduces the risk of a sudden blowout. By contrast, in tires with an inner tube, any puncture deflates the tube almost instantly. As for a tire being regroovable or recuttable, this refers only to the possibility of cutting its tread again when it wears down, not to how it retains air.
