Everything you need to know about Schwalbe road tires.

Information about the tire width of the new Schwalbe Pro One
(model year 2020)

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.

"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).

 


Instructions for the first assembly

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.

The optimal rim
for Schwalbe tubeless racing bike tires

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.

Crotched Type (hooked rim)


SPECIAL NOTES ON HOOKLESS RIMS AND USE WITH SCHWALBE TUBELESS TIRES

  • Hookless rims, also called "Straight Side", are characterised by the absence of the small hook at the end of the rim flank.
  • The official designation for tubeless hookless rims according to ETRTO is "TSS".
  • The rim used must comply with the ETRTO standard for hookless rims (Straight Side).
  • The specified maximum pressure of the tire and rim must be adhered to. 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. This is the rule for tubeless hookless rims (TSS).
  • Hookless or Straight Side rims may only be combined with TLE/TLR tires (Tubeless Easy/Tubeless Ready). The compatible (tubeless) and tire widths specified by the wheel/rim manufacturer must be taken into account. In particular the minimum tire widths. This restriction applies regardless of the intended use (MTB, gravel/cross, city/tour, road bike).
  • Maximum air pressure recommendations for Schwalbe TLE /TLR tires on straight side / hookless rims are as follows:
tire width in mm
Maximum air pressure in bar
18-24 5.5 bar
25-29 5 bar
30-34 4.5 bar
35-39 4 bar
40-44 3.5 bar
45-54 3 bar
55-64 2.5 bar
65-74 2 bar
75-84 1.5 bar

 


SPECIAL FEATURES OF HOOKLESS

  • Lower weight compared to conventional "hooked" rims.
  • Hookless rims produce a rounder tire contour, which has a positive effect on riding characteristics.
  • Due to the comparatively high volume of tires on hookless rims, the practical air pressures are significantly lower. This increases comfort and grip.

SAFE IN OPERATION, EASY TO ASSEMBLE

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
