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.
Only adjust tyre pressures when
the tyres are cold using an accurate
pressure gauge. Do not use the tyre
pressure display on the instruments.
Tyre Wear
As the tyre tread wears down, the tyre
becomes more susceptible to punctures
and failure. It is estimated that 90%
of all tyre problems occur during the
last 10% of tread life (90% worn). It is
recommended that tyres are changed
before they are worn to their minimum
tread depth.

Warning
Operation with excessively worn tyres
is hazardous and will adversely affect
traction, stability and handling which
may lead to loss of control and an
accident.
When tubeless tyres, used without a
tube, become punctured, leakage is
often very slow. Always inspect tyres
very closely for punctures. Check
the tyres for cuts, embedded nails or
other sharp objects. Operation with
punctured or damaged tyres will
adversely affect motorcycle stability
and handling which may lead to loss of
control or an accident.
Check the rims for dents or
deformation. Operation with damaged
or defective wheels or tyres is
dangerous and loss of motorcycle
control or an accident could result.
Always consult your authorised
Triumph dealer for tyre replacement,
or for a safety inspection of the tyres.
In accordance with the periodic
maintenance chart, measure the depth
of the tread with a depth gauge, and
replace any tyre that has worn to, or
beyond the minimum allowable tread
depth specified in the table below:
Under 80 mph
(130 km/h)
2 mm (0.08 in)
Over 80 mph
(130 km/h)
Front 2 mm
(0.08 in)
Rear 3 mm (0.12 in)
