TIRES
This vehicle is equipped with tubeless tires.
WARNING
Reduce the service intervals by half
when the vehicle is used in rainy or
dusty conditions, on rough roads or for
racing.
Check tire inflation at room temperature
at least once a week.
Check the conditions of the tires and
the inflation pressure at room
temperature after the first 600 mi (1,000
km) and thereafter every 4,650 mi (7,500
km), see page 137 (TECHNICAL DATA).
Pressure measurement must always be
carried out when the tires are cold, as
when the tires are warm, pressure will
increase, and result in incorrect
readings.
If the tire is overinflated (pressure is too
high), the result will be an
uncomfortably harsh ride, and riding
comfort will be compromised. Also,
road holding, especially during turns
and in wet conditions, will likewise be
compromised.
If the tire is underinflated (pressure is
too low), the tire may slip on the rim
with consequent loss of control. Again,
road holding and handling
characteristics will be degraded, and
brake performance will be reduced.
When the tire is worn to a point where
any tread is less than 0.12 in (3 mm)
deep, the tire is worn out, and must be
replaced. Also, if a tire suffers a
puncture that is larger than 0.20 in (5
mm) in its longest dimension, the tire
must not be repaired, but should be
replaced.
After a tire is repaired, balance the
wheels. Use only tires that are listed in
the technical data, page 137
(TECHNICAL DATA).
Install only tires that are listed in the
technical data, page 137 (TECHNICAL
DATA), or that have been specifically
approved by aprilia for this vehicle.
WARNING
The use of tires other than those
approved by aprilia may adversely
effect the handling of the vehicle,
leading to an upset and accidents,
which can result in serious injury or
even death.
Make sure that valve caps are fitted on
all tires. This is important to prevent
sudden flats.
WARNING
Do not ride the vehicle if the tire wear
indicators show that the tire is worn
out. Failure to observe this warning can
lead to accidents and result in serious
injury or even death.
Some of the original equipment tires for
this vehicle are provided with wear
indicators. There are several kinds of wear
indicators.
For more information on how to check
wear, contact your Dealer.
Visually check to see if the tires are worn
out. If they are, have them replaced.
If a tire should go flat while you are
riding the vehicle, do not attempt to
continue riding. Avoid abrupt braking
and steering inputs, and avoid shutting
the throttle quickly. Slowly decrease the
throttle setting, moving to the side of
the road, using the engine compression
to slow you to a stop. Non-compliance
with these instructions may cause
accidents which can result in injuries or
even death.
If the tires are very old, even if they are
not completely worn out, they may have
become so hard that road holding is
compromised. In this case, replace the
tires.
Do not install tires with inner tube on
rims for tubeless tires and vice versa.
Repairing, maintenance, changing and
balancing of tires are very important to
your safety, and should only be
performed by qualified mechanics
using the appropriate tools.
For this reason, we suggest that you
have your tires serviced by your Local
aprilia Dealer.
