Tyres
This model is equipped with tubeless tyres, valves, and
wheel rims. Only tyres marked 'TUBELESS' and tubeless
type tyre valves mounted on rims marked 'SUITABLE
FOR TUBELESS TYRES' or 'FOR TUBELESS' can be
used.

Tyres that have been used on a rolling road
dynamometer may become damaged. In some cases,
the damage may not be visible on the external surface
of the tyre. Tyres must be replaced after such use as
continued use of a damaged tyre may lead to instability,
loss of motorcycle control and an accident.
Tyre Pressures
The correct tyre pressures for Rocket III are shown in the
table below. The tyre pressures must always be checked
and adjusted when the tyres are cold.

Correct tyre inflation pressures will provide maximum
stability, rider comfort and tyre life. Tyre pressures must
be checked according to the scheduled maintenance
chart, when the tyres are cold, and adjusted as
necessary.
Incorrect tyre inflation pressures will cause abnormal
tread wear and instability problems that 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.
Tyre WearlWheel Inspection
As the tyre tread wears down, the tyre becomes more
susceptible to puncture and failure. It is estimated that
90% of all tyre failures occur during the last 10% of tread
life (90% worn). It is false economy and unsafe to use
tyres until they are worn to their minimum.
All tyres are fitted with tread wear indicators. When the
tyre becomes worn down as far as the top of a tread wear
indicator, the tyre is worn beyond its service life and must
be replaced. Attention must also be paid to the legal limits
for tread wear, which differ from country to country. Tyres
that have worn to the legal limit in the country or region
in which the motorcycle is operated must be replaced,
even if tread wear has not yet reached the level of the
tread wear indicators.
In accordance with the scheduled 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.
Inspect wheels for cracks, splits and kerb damage. Always
replace wheels that are suspected of having become
damaged.
Operation with excessively worn tyres is hazardous and
will adversely affect traction, stability and handling which
may lead to loss of motorcycle control or an accident.
When tubeless tyres 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. 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
Triumph dealer for tyre replacement, or for a safety
inspection of the tyres.
