6.1.3 Check tyres
1. Check the valve position:
Does not apply to tubeless tyres.
RIsK Of PERsONAl INjuRy AND
MAtERIAl DAMAgE!
In the event of angled valve the base of
the valve can rip off when riding which
causes sudden loss of tyre pressure.
This can lead to hazardous riding situ-
ations, falling, accidents and material
damage.
Have the tyre seating corrected by a
specialist workshop.
You can undertake this job yourself if
you are familiar with fitting and removing
the road wheels (see Chapter 10.1) and
replacing the tyre and tube.
S
Remove the valve nut.
S Check the valve position:
The valves must point directly towards the
centre axis of the road wheel.
