12.0_POSITIONING THE VALVE
Fig. 6 shows a rim in the form of a clock, so that, following the various
processing phases described hereafter, (chapter entitled Mounting and
Demounting), you can position the valve and its sensor correctly so as
not to damage them.
ATTENTION:
To avoid damaging the valve and the pressure sensor, if
the latter is installed, you must always arrange the valve
in the position indicated, following the instructions when
mounting and demounting the tyre. fig.6

13.0_TYRE CLASSIFICATION
LOW PROFILE tyres (UHP) are those in which the height (H) and the width (C) have a ratio lower than 0.5 (i.e. low
profile series 45 stands for a ratio of H/C = 0.45).
For tyres to be considered as LOW PROFILE (UHP), they must also have a maximum speed code of equal to and/or
higher than V.
RUN-FLAT tyres are those which, even when they have no internal pressure, allow you to continue to drive the vehicle
for a preset number of miles and at a preset speed. These parameters change from one manufacturer to another.
The market currently offers 2 different types of RUN-FLAT tyres:
- Those with REINFORCED SIDE (SELF-SUPPORTING) where, thanks to a different mix and a reinforced structure,
the shoulder of the tyre is able to bear the weight of the vehicle even when the pressure in the tyre is zero.
- Those with INTERNAL SUPPORT have a ring inside the rim that bears the side of the tyre when there is no pressure
inside it. The internal support may be made of plastic (Pax-Sistem) or of metal (Support-Ring).
The tyre changer is able to handle all types of LOW PROFILE (UHP) and all types of RUN-FLAT tyres with REINFOR-
CED SIDE; for other types, refer to the specific instructions of the dedicated accessories, if available.
The mounting and demounting procedure is the same, be it a RUN-FLAT tyre with REINFORCED SIDE (SELF-SUP-
PORTING) or a LOW PROFILE tyre (UHP).
ATTENTION:
It is of crucial importance to follow the instructions very carefully in order to avoid
irreparable damages to the tyre, which could compromise the vehicle’s safety.
All tyres that are not within the categories stated above are to be considered as standard tyres.
