14.11.7 Fitting UST tyres
No separate inner tube is needed with UST (universal system tubeless) tyres.
The tyre and rim are connected in such a way that no air can escape.
UST tyres may only be used with a UST rim or a UST wheel.
Have UST tyres fitted by your dealer only. Do not fit UST tyres yourself
unless you have the necessary expertise.
x Only fit UST tyres by hand. Do not use a tyre lever.
x Remove dirt and lubricant before fitting. UST tyres must be free of dust and grease
inside and around the tyre bead.
x Moisten the tyre bead with soap or tyre fitting lubricant before fitting so as not to
damage the UST tyre.
1. Using your hands, press the UST tyre onto the rim from outside.
2. First lift one tyre bead completely over one rim flange, then the other.
3. Centre the UST tyre in the rim well.
4. Centre the valve between the tyre sidewalls.
5. Inflate the UST tyre to the maximum tyre pressure.
6. Check whether the UST tyre is correctly positioned using the fine witness line,
which must be an even distance from the rim all around the UST tyre.
x Use the valve to reduce the tyre pressure if necessary.
