Tyres - APRILIA SR 50 Manual Del Usuario

TYRES

This vehicle is provided with tubeless tyres.
WARNING
Periodically check the tyre inflation
pressure at room temperature, see p. 79
(TECHNICAL DATA).
If the tyres are hot, the measurement is
not correct. Carry out the measurement
especially before and after long rides.
If the inflation pressure is too high, the
ground unevenness cannot be dampened
and is therefore transmitted to the
handlebar, thus compromising the driving
comfort and reducing road holding during
turns.

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 become 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 handling of the vehicle.
Some types of tyres homologated for this
vehicle are provided with wear indicators.
There are several kinds of wear indicators.
For more information on how to check the
wear, contact your Dealer.
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.
After repairing a tyre, have the wheels
balanced.
The tyres must be replaced with other tyres
of the type and model recommended by the
manufacturer, see p. 79 (TECHNICAL DATA);
the use of tyres different from those
prescribed may adversely affect the
manoeuvrability of the vehicle.
Do not install tyres with air tube on rims
for tubeless tyres and viceversa.
