Tire Pressure Monitoring System
(if equipped)
The tire pressures shown on your
instruments indicate the actual tire
pressure at the time of selecting the
display. This may differ from the
inflation pressure set when the tires are
cold because tires become warmer
during riding, causing the air in the tire
to expand and increase the inflation
pressure. The cold inflation pressures
specified by Triumph take account of
this.
Only adjust tire pressures when the
tires are cold using an accurate
pressure gauge. Do not use the tire
pressure display on the instruments.
Tire Wear
As the tire tread wears down, the tire
becomes more susceptible to punctures
and failure. It is estimated that 90% of
all tire problems occur during the last
10% of tread life (90% worn). It is
recommended that tires are changed
before they are worn to their minimum
tread depth.
Minimum Recommended Tread Depth
Warning
Operation with excessively worn tires
is hazardous and will adversely affect
traction, stability and handling which
may lead to loss of control and an
accident.
When tubeless tires, used without a
tube, become punctured, leakage is
often very slow. Always inspect tires
very closely for punctures. Check the
tires for cuts, embedded nails or other
sharp
objects.
Operation
with
punctured or damaged tires 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 tires is
dangerous and loss of motorcycle
control or an accident could result.
Always
consult
your
authorized
Triumph dealer for tire replacement, or
for a safety inspection of the tires.
In accordance with the periodic
maintenance chart, measure the depth
of the tread with a depth gage, and
replace any tire that has worn to, or
beyond the minimum allowable tread
depth specified in the table below:
Under 80 mph
(130 km/h)
0.08 in (2 mm)
Over 80 mph
(130 km/h)
Front 0.08 in (2 mm)
Rear 0.12 in (3 mm)
