Tubeless tires are punctured and are in no way puncture proof. The concept of tubeless tire helps prevent sudden loss of air in the event of a flat tire. Usually, when a nail pierces a tube tire, the tire as well as the inside of the tube are broken and the air can escape the gap between the tube and the tire. However, in a tubeless tire, the nail is housed inside the tire and remains there, with much less air loss depending on the magnitude of the puncture. You can drive in this state without causing any damage to the tire (except if the puncture is severe, or if the nail is abnormally large).
The repair of a tubeless tire is very simple compared to a tubed tire and can be made in the movement whereever the air can be filled, like a petrol pump etc with the help of a kit. In addition, its safer at high speeds in case of a high speed puncture. Tubeless tires do not explode, but that is due to negligence with regard to air pressure, installation or manufacturing defect. But that's a rare case though. Personally, I've done a 270 km long trip with a nail in the tire and that too in a ghat section followed by a road.
Tubeless tires (in some Commonwealth countries) are tires that do not require a separate inner tube. Unlike tires using a separate inner tube, tubeless tires have continuous ribs integrally molded into the tire bead so that they are forced by the air pressure inside the tire to seal with the flanges of the wheel metal flange .
Many patents had been filed covering the tubeless tires. Killen Tire applied for a patent in 1928 and was awarded the GB 329955 patent in the United Kingdom in 1930. Wing-foot Corporation, a subsidiary of Goodyear Tire was granted a patent in South Africa in 1944. Due to technical problems, most of these designs only saw limited production or were abandoned. Frank Herzegh who worked for BF Goodrich applied for a patent in 1946 and finally received US patent 2587470 in 1952 in the United States. In 1955 the tubeless tires became standard equipment in new cars. Goodrich had to defend his patent in court several times, due to the similarities of previous designs. The main difference between the design of BF Goodrich and his predecessors was the use of butyl rubber, which was more resistant to air leaks than the natural rubber used in the other designs.
