By increasing thr inflation pressure to
2,25 kg/sq.(n~. (32 Ib,'sq.in.) the safe maximum
permissible sptd may be increased to 153 k.p.h.
(95 m,p.h.).
The approved tyres are supplied with 116 moulded
holes fnr the acceptance of studs. If studs are to be
fitted
all holes should be utilised.
It is recommended that, Secomet P2-140 studs
are used and when fitting studs to a tyre ensure
that they protrude between
1,5 mm. and 2,O mm.
(0.06 in, and 0.79 in.).
Whenever possible a tyre should be studded from
new, however, it is acceptable to stud a partially
worn tyre provided the studs do not protrude beyond
4,0 mm. (0.157 in,) when fitted.
If
this limit is
exceeded the tyre must be considered too worn to be
successfully studded.
Snow chains
On all types of snow chains it is important to note
that if the chains are fitted too tightly and the car
is driven at fast speeds, or for long distances, on
roads which are free of snow, irreparable damage to
the tyres and the chains will occur.
Three types of snow chains are recommended,
they are as follows.
(a) Kantenspur 07-745
(b) Union
S2-3082
(c) Union S2-3081
The Kantenspur 07-745 snow chains are
recommended for use on front wheels when HR 70
HR 15
(235,'70 HR 15) tyres are fitted.
Union S2-3082 snow chains are recommended as
an alternative to the Kantenspur.
Union
S2-3081 snow chains are recommended for
use on
Dunlop Weathermaster 205-15 SP 44 radial-
ply tyres.
These snow chains can be used on all four
wheels or to the rear wheels only when HR 70
HR 15
(235/70 HR
i5)
tyres are fitted to the front
wheels.
Union S2-3081 snow chains can also be fitted to
other 205-15 radial-ply and 8.1 5 H
15 cross-ply
tyres.
When snow chains are fitted, a speed limit of
50
k.p.h. (31 m.p.h.) must not be exceeded on snow
free roads.
Note
It is advisable when fitting snow chains
to wear the plastic gloves provided.
?'he spare links supplied with the kit
are only intended to permit emergency
road side repairs to be carried out if a
chain is damaged

Kantenspur snow chains-To fit
1.
Ensure that the car is standing on a level
surface.
2. Apply the handbrake/parking brake.
3.
Holding the chain apart by the red plastic
handles, ensure that it hangs as shown in Figure
R14 inset
A.
4.
Position the chain in an oval shape
immediately before or behind the front wheel and
move the car until the tyre is situated centrally
inside the chain (see Fig.
R14
inset
B).
5.
Holding the red handles lift the chain over the
tread of the tyre (see Fig.
R14 inset
C).
6.
Lift the upper chain and place it completely
over the full width of the tyre (see Fig.
R14
inset
D).
7.
Fit the rubber tensioner supplied with the kit
horizontally near the bottom of the tyre and move the
wheel one quarter of a revolution in either a forward
or rearward direction (see Fig.
R14
irzset
E).
8.
Remove the rubber tensioner, disengage the
fastener and pull the chain as indicated by the
arrow to produce tension (see Fig.
R14 inset F).
9.
To take up the remaining chain, thread it
through the outer circumference as shown in Figure
R14 inset
G
and hook in the fastener.
10.
Check to ensure that the fastener is hooked
securely in the side of the chain and that a
clearance of approximately
12,7 mm. (0.5 in.) exists
between the chain and the tyre. This clearance is
necessary as snow chains
should not be fitted too
tightly.
11. Repeat Operations 1 to
10 on the other front
wheel.
