What does tubeless tire mean?

Tubeless tire refers to a tire without an inner tube, commonly known as an atomic tire or vacuum tire. This type of tire ensures good airtightness between the tire and the rim by utilizing the airtight layer on the inner wall of the tire and the bead. The outer tire also serves the function of an inner tube. The tire does not come with an inner tube, as the tire itself has an inner tube structure, and air is filled directly into the tire. Tubeless tires are now widely used and have replaced tires with inner tubes. Tubeless tires have better airtightness, ensuring long-term air retention, lower operating temperatures, longer service life, simple structure, and lighter weight, which is beneficial for high-speed driving. Since the airtight layer of the tire is a membrane tightly adhered to the inner wall of the tire, the tire is less prone to heat buildup during high-speed driving. When the tire is punctured, the pressure does not drop sharply, allowing the vehicle to continue driving safely for a certain distance.
Having driven for a lifetime, I have a deep understanding of tubeless tires. They are tires without inner tubes, and the traditional ones with inner tubes are rarely seen nowadays. Tubeless tires have an airtight layer that directly adheres to the wheel rim for inflation, eliminating the need for an inner tube. The benefits are high safety: if you run over a nail or get a small puncture on the road, the air leaks slowly, preventing sudden blowouts, allowing you to drive smoothly to a repair shop. During maintenance, a single inflation lasts much longer compared to old-style inner tubes, which required frequent checks. Repairs are also convenient—some small punctures can be fixed simply by inserting a rubber plug, saving time and effort. Additionally, these tires provide better grip in rainy conditions or on mountain roads, reducing the risk of skidding. Almost all modern vehicles use them, and since their invention in 1947, they have become widely adopted, marking a significant advancement in tire technology.
As an enthusiast who frequently deals with cars, I believe tubeless tires are the best companion for daily driving. They don't have inner tubes, and the tire casing itself is leak-proof, directly mounted on the rim. The benefits of this design are significant: less prone to pressure loss when punctured, reducing the risk of losing control; slightly lighter weight, improving fuel efficiency by about 3%; and easier repairs, requiring only external patching without removing the entire wheel. In contrast, older tires with inner tubes pose much higher risks at high speeds or on long trips. When choosing tires, I recommend regularly checking tire pressure and wear. Tubeless versions are usually slightly more expensive but have a longer lifespan, making them cost-effective overall. Don't forget that new cars come standard with these nowadays.
