Tyre Inflation Pressures
Correct tyre inflation pressures will
provide maximum stability, rider comfort
and tyre life. Always check tyre
pressures before riding when the tyres
are cold. Check tyre pressures daily and
adjust if necessary (see Specification
section for correct inflation pressures).
Alternatively, ask your authorised
Triumph dealer to inspect your wheels
and tyres.
Tyre Pressure Monitoring System
(if fitted)
The tyre pressures shown on your
instruments indicate the actual tyre
pressure at the time of selecting the
display. This may differ from the inflation
pressure set when the tyres are cold
because tyres become warmer during
riding, causing the air in the tyre to
expand and increase the inflation
pressure. The cold inflation pressures
specified by Triumph take account of
this.
Owners must only adjust tyre pressures
when the tyres are cold using an
accurate pressure gauge, and must not
use the tyre pressure display on the
instruments.
Tyre Wear
As the tyre tread wears down, the tyre
becomes more susceptible to punctures.
It is estimated that 90% of all tyre
problems occur during the last 10% of
tread life (90% worn). It is therefore not
recommended to use tyres until they are
worn to their minimum.
Warning
Incorrect tyre inflation will cause
abnormal tread wear and instability
problems which may lead to loss of
motorcycle control and an accident.
Under-inflation may result in the tyre
slipping on, or coming off the rim.
Over-inflation will cause instability and
accelerated tread wear.
Both conditions are dangerous as
they may cause loss of motorcycle
control and an accident.
Warning
Tyre pressures which have been
reduced for off-road riding will impair
on-road stability. Always ensure the
tyre pressure are set as described in
the Specification section for on-road
use.
Operation of the motorcycle with
incorrect tyre pressures may cause
loss of motorcycle control and an
accident.
