TUBELESS TYRES (UST TYRES)
Tubeless tyres (a) are also referred to as “tubeless ready“. The rims are provided
with specific valves, have an entirely enclosed rim base and partly also a specific
rim shape. There is no inner tube.
Tyre removal
Deflate the tubeless/UST tyre completely (b). Press the tyre from one side to-
wards the centre of the rim, until the tyre bead is loose in the rim base.
Start removing the tyre close to the valve and lift one tyre side over the edge of
the rim with your fingers.
After you have pulled the entire tyre side over the rim edge press, if necessary,
the other tyre side into the rim base and remove this side also from the rim.
N OTICE
Do not use tyre levers (c) in order to avoid damage to the sensitive sealing
lip on the tyre bead!
It is recommended that you use the tools of the respective tyre manufactur-
er for removal as they are designed to be used together.
Puncture Assistance – Repair
In case of a puncture, tubeless tyres can also be used with inner tubes. Remove
any available perforating object from the tyre first and remove the valve from
the rim. Insert a slightly inflated new inner tube into the tyre. Mount the tyre as
described in chapter “Clincher and Folding Tyres”. You may need tyre levers for
this purpose.
WARNING
Improper mounting can lead to malfunctioning, tyre damage or even brake
failure. Therefore, strictly observe the instructions of the component manu-
facturer.
