HOOKLESS RIMS
Important: Correct tire pressure
The correct tire pressure is important when using Schwalbe TLE/TLR tires with hookless rims. According to the ETRTO (European Tyre and Rim Technical Organization), hookless rims have a maximum pressure of 5 bar for road bikes. This tire pressure must be adhered to even if the maximum pressure stated on the sidewall of the tire shows a higher maximum pressure. If the specified maximum pressure of the rim is lower than that of the tire, the maximum pressure of the rim must be complied with. There are also restrictions imposed by the rim manufacturer with regard to the choice of tire, which must also be observed. In addition, many rim and wheel manufacturers recommend a minimum tire width of 28 mm in order to be able to ride the low air pressure without any problems.
Schwalbe tires safe thanks to high-strength bead core
Schwalbe's tubeless tires are safe on hookless rims if they are used with the correct tire width and air pressure. This is due to the bead core, for which one property is essential: it must be high-strength and must not expand. This is ultimately more expensive in production, but for such a safety-relevant component, it is completely non-negotiable for us at Schwalbe. Thanks to the high-strength core, the tire does not expand under pressure and stays on the rim. Schwalbe builds tires that fit perfectly on ETRTO-compliant rims. Schäfermeier: "Our bead core is extremely strong and stable and makes no compromises when it comes to safety. At the same time, it enables easy fitting without any tools." The inner diameter of the bead core also plays a decisive role: at Schwalbe, it has perfect dimensions so that the tire fits securely and is easy to mount and inflate.
