A tubeless tire (also spelled as tubeless tyre in Commonwealth English) is a pneumatic tire that does not require a separate inner tube.. Unlike pneumatic tires which use a separate inner tube, tubeless tires have continuous ribs molded integrally into the bead of the tire that are forced by air pressure into a flange on the metal rim of the wheel, sealing the tire to the rim.
The tire trademark is "Terrainarmor". Bridgestone is developing the Bridgestone Air-Free Concept Tire, which can hold 150 kg (330 lb) per tire. [13] The Energy return wheel (ERW) has the outer edge of the tire connected to the inner rim by a system of springs. The springs can have their tension changed to vary the handling characteristics.

Bead tires, whether with an inner tube or tubeless, cannot be ridden flat, as the tire may separate from the rim. In contrast, tubular tires have the tubing sewn to the tire, allowing them to be ridden flat if punctured. [3] Tubeless tires are reported to be more comfortable if properly installed. [1] [2] [3]

Tire identification labels. Automotive tires are described by several alphanumeric tire codes (in North American English) or tyre codes (in Commonwealth English), which are generally molded into the sidewall of the tire. These codes specify the dimensions of the tire and its key limitations, such as load-bearing ability and maximum speed.
The status of whitewall tires versus blackwall tires was originally the reverse of what it later became, with fully black tires requiring a greater amount of carbon black and less effort to maintain a clean appearance these were considered the premium tire; since the black tires first became available they were commonly fitted to many luxury cars through the 1930s.
Tire factories start with bulk raw materials such as synthetic rubber (60% -70% of total rubber in the tire industry [2] [3]), carbon black, and chemicals and produce numerous specialized components that are assembled and cured. The tire is an assembly of numerous components that are built up on a drum and then cured in a press under heat and ...
