TYRE INFLATION PRESSURE
SPECIFICATIONS
The brand, type and size of the specifi c tyres for
this vehicle are given on (SPECIFICATIONS).
TYRE PRESSURE
For the tyre pressures see (SPECIFICATIONS).
The right tyre pressure ensures that the vehicle
is in the best conditions for:
- better ride ability;
- better drive ability;
- longer tread life;
- better road holding.
Under infl ation of the tyre results in:
- irregular wear;
- poorer drive ability and road holding;
- higher fuel consumption;
- possibility of bursting (due to increase in working
temperature).
Over infl ation of the tyre results in:
- irregular wear;
- poorer drive ability and road holding;
- jeopardised ride ability and comfort.
CHECKS
For the maintenance intervals, see (PERIODIC
MAINTENANCE CHARTS), under:
- Tyres;
- Tyre pressure;
- Wheels/Tyres.
Check tyre wear and pressure (at ambient temper-
ature) before and after every long journey and as
described in the SPECIFICATIONS.
NOTE: ambient temperature of the tyre means that
the vehicle has been stationary for at least three
hours or that it has travelled in this time a distance
of no more than 2 km (1 mi).
If there is no choice but to check the pressure after
having travelled many kilometres, remember that
the measured values are 30-40 kPa (0.3- 0.4 bar)
higher than those measured at ambient temper-
ature. This is normal, so do not defl ate the tyres to
obtain the recommended values (valid for ambient
temperature), otherwise the tyre pressure will be
insuffi cient.
NOTE: if possible always use the same pressure
gauge to check the pressure, so as not to risk wrong
values caused by the variability between different
gauges. If you note a loss of pressure, carefully
check the tyre and try to fi nd the point from where
the air is leaking.
At every pressure control, check for:
- damage, wear, foreign matter lodged in the tread.
Check very carefully for:
- bulging on the tread or the side wall of the tyre. If
present, the tyre must be changed;
- side wall cracks, cuts or slits. If present or if the
fabric breaker is visible, the tyre must be changed;
- an excessively smooth tread.
NOTE: certain types of tyres have wear indicators;
several types exist. Speak to the dealer, who can
give you information also regarding the methods
of checking wear.
TREAD DEPTH
The minimum tread height must never be less than
1 mm (0.03 in) and in any case not less than what is
prescribed by the legislation in force in the country
where the vehicle is used.
!
CAUTION
If the tyre is worn or if any punc-
ture in the tread area is larger
than 5 mm, the tyre must be
changed.
