Checks and inspections

3.b - Checking the tyres
-
Check the tyres for signs of external damage,
foreign bodies and wear and tear; the entire
surface of the tyre must conform to the original
profile.
· The cord weft located under the rubber layer
must not be exposed.
· The tyres must not be dented or cracked.
-
Remove any foreign bodies (thorns, stones,
fragments of glass, etc.) by hand, or with a
small screwdriver (proceed with caution).
Check for air leaks. In the event of leaks, replace
the inner tube (see paragraph "6" - Section
"07").
3.c - Checking the tyre valves
-
If the bicycle is ridden when the tyre pressure
is too low, it may displace the position of the
tyre and inner tube on the wheel rim, so that
the valve assumes an oblique position. In this
case, the base of the valve may be torn away
from the inner tube while the bicycle is in use,
resulting in a sudden loss of tyre pressure.
· Check the position of the valves: they must
be pointing towards the centre of the wheel
(fig. "11").
· If necessary, deflate the tyre, loosen the
valve nut (if present) and attempt to correct
the position.
Re-tighten the valve nut (if present) and
re-inflate the tyre.

3.d - Checking the tyre pressure
-
If the tyre pressure is too low:
· it may displace the position of the tyre and
inner tube on the wheel rim, so that the
valve assumes an oblique position. In this
case, the base of the valve may be torn away
from the inner tube while the bicycle is in
use, resulting in a sudden loss of tyre pres-
sure.
· the tyre may become detached from the
wheel rim on curves
· the frequency of faults is increased.
Tyre pressure should be proportional to the
weight of the rider and the total load of the
bicycle.
The table on the right indicates the reference
pressure values.
These values are purely indicative. Contact
your vendor or a tyre specialist for more in-
formation.
Always respect the minimum and max-
imum pressure values indicated on the
tyre.
