Triumph Trident 2023 - 10.12.3 Tyre Wear; 10.12.4 Minimum Recommended Tread Depth

MAINTENANCE AND ADJUSTMENT
169
The tyre pressures shown on your
instruments indicate the actual tyre
pressure at the time of selecting the
display. This may differ from the
inflation pressure set when the tyres
are cold because tyres become warmer
during riding, causing the air in the tyre
to expand and increase the inflation
pressure. The cold inflation pressures
specified by Triumph take account of
this.
Only adjust tyre pressures when the
tyres are cold using an accurate
pressure gauge. Do not use the tyre
pressure display on the instruments.
Tyre Wear
As the tyre tread wears down, the tyre
becomes more susceptible to punctures
and failure. It is estimated that 90% of
all tyre problems occur during the last
10% of tread life (90% worn). It is
recommended that tyres are changed
before they are worn to their minimum
tread depth.

WARNING
Riding with damaged or defective
wheels and/or excessively worn,
punctured or damaged tyres will
affect traction, handling and stability.
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 wheel rims for dents or
deformation.
For tyre replacement or for a safety
inspection of the tyres, contact a
competent person with the specialist
knowledge and technical
understanding of motorcycles, such as
an authorised Triumph dealer.
Riding with damaged wheels and tyres
is dangerous and may lead to loss of
motorcycle control which could result
in serious injury or death.
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 allowable tread
depth specified in the table below:

(130km/h)

Over 80mph
(130km/h)
