What is the difference between tubeless tires and tube-type tires?

Vacuum tires, also known as tubeless tires, are the counterpart to tube-type tires. The following is a relevant introduction: 1. Difference: The main difference between tubeless tires and tube-type tires is the presence or absence of an inner tube. 2. Development: The original pneumatic tires, due to their tread design focusing on grip and wear resistance, could not effectively contain air. Therefore, a specialized soft and dense inner tube with good air retention was used to seal the air, combining with the tire and rim to form a complete tire system. The more components a system has, the higher the probability of failure. Hence, tubeless tires (i.e., vacuum tires) were later invented. The principle involves simplifying the original inner tube into a layer of airtight coating applied to the inner wall of the tire to seal the air. Correspondingly, the rim structure was also adjusted. This type of tire with an airtight coating, combined with the rim, forms a sealed space to contain the air. Thus, the original three components (tire casing, inner tube, and rim) evolved into two components (tire and rim), eliminating the intermediate inner tube. Therefore, it is commonly referred to as a vacuum tire (though it is not a vacuum in the physical sense, merely indicating the absence of an inner tube).
I've been driving for over ten years and found that tubeless tires and tube-type tires mainly differ in structure. Tubeless tires don't require an inner tube, sealing air directly with the rim edges. When leaking, air is released slowly, making sudden blowouts less likely, and repairs are simpler—just inject some tire sealant. Tube-type tires have a rubber inner tube holding the air, which flattens immediately if punctured, posing much higher risks. For daily use, tubeless tires are more lightweight and safer, especially on highways, and can even save some fuel. However, if the rim is damaged, the wheel needs repair. Some older cars can switch to tubeless tires as long as the rim is compatible. Overall, from a safety perspective, I highly recommend tubeless tires.
As a long-haul driver, the difference between these two types of tires is quite significant. Tubeless tires don't have an inner tube; air is directly pressurized between the tire body and the rim. In case of a blowout, air leaks slowly, allowing you to drive to a repair shop. In contrast, tube-type tires rely on the inner tube to maintain airtightness—a blowout leads to instant loss of control, and maintenance is cumbersome, requiring time-consuming and labor-intensive wheel removal to replace the inner tube. Tubeless tires are lighter, more fuel-efficient, and easier/faster to patch. Though initially more expensive, they prove more cost-effective in the long run. Most new vehicles now come with tubeless tires, and older cars can be retrofitted. If you frequently drive on rough roads or carry heavy loads, tube-type tires may offer better durability, but their safety performance falls far short.
