Preliminary Checks - SICE S 45 Manuel D'instructions

tyres, and the type with an internal support may be made from plastic (Pax-System) or metal (Support-Ring).
These tyres' characteristics make mounting operations more problematical, and it is extremely important not to
cause damage during mounting and demounting operations, as this may reduce the vehicle's safety level.
The device is able to work safely on all self-supporting run-flat tyres with the aid of
the special accessory kit, developed to prevent possible damage to the tyre.
For other types of run-flat tyre, refer to specific instructions supplied with the special
accessories.
The mounting and demounting procedure is the same for both self-supporting run-flat, and
low profile and UHP tyres.
WARNING: It is essential to follow the instructions closely to avoid
irreparable damage to the tyre, which might put the vehicle's safe-
at risk.
This manual comes complete with a WDK leaflet detailing all the possible forms of damage to
the tyre if the correct safety measures are not adopted, regardless of the tyre changer used.
WARNING: Figs. S1 and S2 show the points with the highest risk of damage during demount-
ing (S1) and mounting (S2):
these are the traction points where the tyre is very taut against the edge of the rim.

PRELIMINARY CHECKS

Comply with work-place safety regulations.
All operators must have suitable clothing, gloves, safety footwear, etc.
The tyre and rim must be cleaned thoroughly.
Identify the parts correctly: both the tyre and the rim.
Rims have their diameter, width, Hump number, etc. data stamped on their surfaces.
E.g. a marking 7.5Jx16H2
7.5 Indicates the nominal width of the rim
J
is the size of the flange
16 is the nominal diameter of the rim
H2 indicates a double hump
Tyres are marked with a large amount of information, including dimensions, type, year of construction, etc.
E.g. in a tyre marked 205/45 R 16 91V
205 Indicates the width of the tyre, i.e. the distance between the sidewalls in millimetres.
45 States the ratio (as a percentage) between the height and width of the cross-section.
R
stands for radial.
16 states the keying diameter (rim diameter) in inches. 91 indicates the maximum load
per wheel;
V is the maximum speed code (T: 190 km/h H: 210 km/h, etc.).
WARNING: Mounting tyres on rims which have a different keying value is absolutely forbid-
