Tire Inflation Pressures
Warning
Incorrect tire inflation will cause
abnormal tread wear and instability
problems which may lead to loss of
motorcycle control and an accident.
Underinflation may result in the tire
slipping on, or coming off the rim.
Overinflation will cause instability and
accelerated tread wear.
Both conditions are dangerous as they
may cause loss of motorcycle control
and an accident.
Warning
Tire pressures which have been
reduced for off-road riding will impair
on-road stability. Always make sure
that the tire pressures are set as
described in the Specification section
for on-road use.
Operation of the motorcycle with
incorrect tire pressures may cause loss
of motorcycle control and an accident.
Correct tire inflation pressures will
provide maximum stability, rider comfort
and tire life. Always check tire pressures
before riding when the tires are cold.
Check tire pressures daily and adjust if
necessary (see Specification section for
correct inflation pressures). Alternatively,
ask your authorized Triumph dealer to
inspect your wheels and tires.
Tire Pressure Monitoring System
(TPMS) (if equipped)
The tire pressures shown on your
instruments indicate the actual tire
pressure at the time of selecting the
display. This may differ from the
inflation pressure set when the tires are
cold because tires become warmer
during riding, causing the air in the tire
to expand and increase the inflation
pressure. The cold inflation pressures
specified by Triumph take account of
this.
Owners must only adjust tire pressures
when the tires are cold using an
accurate pressure gage, and must not
use the tire pressure display on the
instruments.
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.
