Minimum Recommended Tread Depth; Important Tyre Information - Triumph Rocket III Service Manual

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, imbedded 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.
Minimum Recommended Tread Depth
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 legally allowable tread depth.
In countries where there is no legal minimum tread
depth, Triumph recommends the following;
Speed Minimum Tread Depth
Under 130 km/h 2 mm (0.08 in)
(80 mph)
Over 130 km/h (80 mph) Rear 3 mm (0.12 in)
Front 2 mm (0.08 in)
Triumph motorcycles must not be operated above
the legal road speed limit except in authorised
closed course conditions.
Only operate this Triumph motorcycle at high speed
in closed-course on-road competition or on closed
course race tracks. High speed operation should
only then be attempted by riders who have been
instructed in the techniques necessary for high
speed riding and are familiar with the motorcycle's
characteristics in all conditions. High speed
operation in any other circumstances is dangerous
and may lead to loss of motorcycle control and an
accident.

Important Tyre Information
All Triumph motorcycles are carefully and extensively
tested in a range of riding conditions to ensure that
the most effective tyre combinations are approved for
use on each model. It is essential that approved tyre
combinations are used when purchasing replacement
tyres as the use of non approved tyres or approved
tyres in non approved combinations may lead to
motorcycle instability. Always refer to the owner's
handbook data section for details of approved tyres
and tyre combinations.
If a tyre sustains a puncture, the tyre must be
replaced. Failure to replace a punctured tyre, or
operation with a repaired tyre can lead to instability,
loss of control or an accident.
Never use an inner tube to repair a punctured tyre.
The rough surface inside the tyre can chafe the tube
leading to instability, rapid deflation, loss of
motorcycle control and an accident.
Do not install tube-type tyres on tubeless rims. The
bead will not seat and the tyres could slip on the
rims, causing tyre deflation that may result in a loss
of motorcycle control and an accident.
The use of tyres other than those listed in the
specification section of the owner's handbook may
adversely affect handling leading to loss of
motorcycle control or an accident. Use the
recommended tyre options only in the combinations
given in the owner's handbook. Do not mix tyres
from different manufacturers or tyres from the same
manufacturer but from another option.
