If, on the contrary, the inflation pressure is too
low, the tyre sides (1) are under greater stress and
the tyre itself may slip on the rim or it may be-
come loose, with consequent loss of control of
the vehicle.
In case of sudden braking the tyres could even get
out of the rims.
Further, the vehicle could skid while turning.
Check the surface and the wear of the tyres, since
tyres in bad conditions can impair both the grip
and the controllability of the vehicle.
Some types of tyres homologated for this vehicle
are provided with wear indicators.
There are several kinds of wear indicators.
Visually check if the tyres are worn and in this
case have them changed.
If the tyres are old, even if not completely worn
out, they may become hard and may not ensure
good road holding.In this case, have the tyres
changed.
Change the tyre when it is worn out or in case of
puncture on the tread side, if the puncture is
larger than 5 mm (0.196 in).
After repairing a tyre, have the wheels balanced.
Use only tyres in the size suggested by aprilia,
see TECHNICAL DATA.
Do not install tyres with air tube on rims for tube-
less tyres and viceversa.
Make sure that the tyres always have their valve
sealing caps on, to prevent them from suddenly
going flat.
Change, repair, maintenance and balancing opera-
tions are very important and should be carried out
by qualified technicians with appropriate tools.
If the tyres are new, they may still be covered with
a slippery film: drive carefully for the first miles.
Do not oil the tyres with unsuitable fluids.
