MAINTENANCE AND ADJUSTMENT

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.

Warning
Riding 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. Riding 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. Riding with damaged or
defective wheels or tires is dangerous
and may lead to loss of control and an
accident.
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)
Tire Replacement
All Triumph motorcycles are carefully
and extensively tested in a range of
riding conditions to make sure that
the most effective tire combinations
are approved for use on each model.
It is essential that approved tires and
inner tubes (if installed) mounted in
approved combinations, are used when
purchasing replacement items. The use
of non-approved tires and inner tubes,
or approved tires and inner tubes in
non-approved combinations, may lead
to motorcycle instability, loss of control
and an accident.
A list of approved tires and inner tubes
specific to your motorcycle are available
from your authorized Triumph dealer, or
on the Internet at www. triumph. co. uk.
Always have tires and inner tubes
mounted and balanced by your
authorized Triumph dealer who has the
necessary training and skills to ensure
safe, effective installation.
