THE OPTIMAL RIM FOR SCHWALBE TUBELESS RACING BIKE TIRES

For safety and performance, the tire and rim on the bike must be perfectly matched. This applies all the more to tubeless tires. In addition to the classic hooked rims (crotched type), so-called “hookless” rims (straight side) are becoming increasingly popular on current model bikes. Hookless rims in particular place high demands on tubeless tires for safe operation. The Schwalbe TLR/TLE models (from model year 2020) are designed to meet these special requirements, especially in the bead core area, and are therefore generally compatible.

Rim manufacturers often use wider inner bead widths for their hookless rims. The air pressure should therefore be reduced accordingly, as the real volume of the tire increases with wider inner rim widths.

According to the ETRTO (European Tyre and Rim Technical Organisation), hookless rims have a maximum pressure of 5 bar for road bikes. This maximum tire pressure must be adhered to, or less if the maximum pressure stated by the rim/wheel manufacturer is lower, even if the maximum pressure printed or embossed on the tire is higher. Therefore, if the specified maximum pressure of the rim is lower than that of the tire, the maximum pressure of the rim must be observed. There are also restrictions imposed by the rim manufacturer with regard to the choice of tire, which must also be observed. 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.
