What requirements must the optimum wheel for Schwalbe tubeless road bike tires meet?
To the requirements >>
The design dimensions of the Schwalbe Pro One (TLE, Tube Type) and Schwalbe Pro One TT road bike tires are based around a nominal standard rim width of 19C, the standard for modern road bike rims (formerly 15C). This has an effect on the real tire dimensions when mounted and should be taken into account when buying tires in order to ensure trouble-free mounting and best product performance.

x = tire/rim combination not recommended
"C": Crotched (rim flank with hook - standard rim)
"TC": Tubeless Crotched (rim flank with hook - tubeless rim)
"TSS": Tubeless Straight Side (rim flank without hook - tubeless rim)
Note: TSS rims may only be combined with TLE/TLR tires (Tubeless Easy/Tubeless Ready). Regardless of whether they are used tubeless or with tube.
The tire width may vary by +/- 1 mm depending on the rim that is used.
All tire dimensions were determined at maximum tire pressure. (Caution: Due to different rim shapes, the maximum allowable air pressure of the rim must be taken into account. If the indicated maximum allowable pressure of the rim is lower than that of the tire, always comply with the maximum pressure of the rim. This can lead to different tire dimensions).
Overview applies only to the tire models Schwalbe Pro One "TLE" "TT" and "Tube Type" with the tread markings HS493 and HS493A (model year 2020).
The turn-up construction integrates Tubeless Easy technology in the most progressive way possible. This is what makes the tire so supple and comfortable. Riding this tire feels just like the velvety motion of a classic tubular tire.
Instructions for the first assembly: Schwalbe Pro One and Schwalbe Pro One TT Tubeless Easy tires must be used with Doc Blue tire sealant. At least 30 ml, preferably 60 ml per tire. The tire must be run for at least 25 km directly after the sealent is added. If the instructions for the first assembly are ignored, the sealing of the tire cannot be guaranteed.

For safety and performance, the tire and rim on the bicycle must be optimally 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 in current models. 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 fundamentally compatible.
Due to the design, the tire volume increases compared to the conventional hook rim because of the larger inner rim width. Therefore, the air pressure is lower than with normal rims. To ensure safety and optimum performance, the air pressure must be set lower than with the conventional set-up with hook rim. Regardless of the rim contour (hookless or hooked rim), Schwalbe recommends only using rims/wheels that are explicitly approved for tubeless use.

As experts in tubeless technology, we work hand in hand with wheel and rim manufacturers as well as industry committees. We check the compatibility of wheels, rims and tires at our in-house test center. The results are summarized in the compatibility overview. If a wheel or rim is missing from the overview, we would be happy to hear about it at info@schwalbe.com
