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

Minimum Recommended Tread Depth
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 legally allowable tread depth specified below:
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.
WheelslTyres
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.
Accurate wheel balance is important for safe, stable
handling of the motorcycle. Do not remove or change
any wheel balance weights. Incorrect wheel balance may
cause instability leading to loss of motorcycle control and
an accident.
When wheel balancing is required, such as after tyre
replacement, see your authorised Triumph dealer.
Only use self-adhesive weights. Clip-on weights will
damage the wheel and tyre potentially resulting in tyre
deflation, loss of motorcycle control and an accident.
