Tire Inflation Pressures; Tire Wear - Triumph Thunderbird LT Owner's Handbook Manual

Warning
Inner tubes must only be used on
motorcycles fitted with spoked wheels and
with tires marked 'TUBE TYPE'.
Some brands of approved tires marked
'TUBELESS' may be suitable for use with
an inner tube. Where this is the case, the
tire wall will be marked with text
permitting the fitment of an inner tube (see
illustration below).
Use of an inner tube with a tire marked
'TUBELESS', and NOT marked as suitable
for use with an inner tube, or use of an
inner tube on an alloy wheel marked
'SUITABLE FOR TUBELESS TIRES' will
cause deflation of the tire resulting in loss
of motorcycle control and an accident.

Tire Inflation Pressures

Correct inflation
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 the
Specification section for details of the correct
inflation pressures.
Warning
Incorrect tire inflation will cause abnormal
tread wear and instability problems that
may lead to loss of control and an accident.
Under-inflation may result in the tire
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 control leading to an accident.

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).
