MAINTENANCE

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 temperature. This is normal, so do not deflate the tyres to obtain the recommended
values (valid for ambient temperature), otherwise the tyre pressure will be insufficient.
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 find
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.
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.
