Wheel Bolts; Winter Tyres - Skoda Citigo Owner's Manual

Note
It is not normally possible to fit wheels from other models of cars for technical
reasons. This may also apply in certain circumstances to the wheels of the same
type of vehicle.

Wheel bolts

Wheels and wheel bolts are matched to each other in terms of design. Each time
you fit other wheels - e.g. light alloy wheels or wheels with winter tyres - you
must therefore also use the matching wheel bolts of the correct length and shape
of spherical cap. This is essential to ensure that the wheels are tightly fitted and
that the brake system operates properly.
If you retrofit wheel trims (or have this done), please also ensure that an ade-
quate flow of air remains assured for cooling the brake system.
Authorised ŠKODA Service Partners are instructed in the technical possibilities
which exist regarding converting or retrofitting tyres, wheels and wheel trims.
WARNING
● In case of incorrect treatment of the wheel bolts, the wheel can loosen
when the car is moving - risk of accident!
● The wheel bolts must be clean and must turn easily. However, they must
never be treated with grease or oil.
● If the wheel bolts are tightened to a too low tightening torque, the rim can
come loose when the car is moving - risk of accident! A tightening torque
which is too high can damage the bolts and threads and this can result in per-
manent deformation of the contact surfaces on the rim.
CAUTION
The prescribed tightening torque of the wheel bolts for steel and light alloy
wheels is 110 Nm.

Winter tyres

The handling of your vehicle will be significantly improved when driving on wintry
roads if you fit winter tyres. Summer tyres do not offer the same grip on ice, snow
and at temperatures below 7 °C because of their construction (width, rubber
blend, tread pattern).
Using the system Safety
Winter tyres must be mounted on all four wheels to obtain the best handling
characteristics.
You must only fit those types of winter tyre which are approved for your vehicle.
The permissible sizes of winter tyres are stated in your vehicle documents. Ap-

provals may differ because of national legislation.
Please remember that the tyres should be inflated to 20 kPa (0.2 bar) more than is
the case for summer tyres ⇒ p age 118.
Winter tyres no longer offer the same winter performance once the tyre tread has
worn down to a depth of about 4 mm.
Ageing also causes winter tyres to lose most of their winter performance proper-
ties - even in cases where the remaining tread depth is still clearly more than 4
mm.
Speed restrictions apply to winter tyres as well as to summer tyres ⇒ p age 120,
⇒
You can fit winter tyres of a lower speed category to your vehicle provided that
you also do not drive faster than the permissible maximum speed for such tyres,
even if the possible maximum speed of your vehicle is higher. The corresponding
tyre category can damage the tyres when exceeding the permissible maximum
speed.
Please pay attention to the notes if you decide to fit winter tyres ⇒ p age 118.
Please contact your specialist garage if there are any points which are not clear
who will be able to provide you with information regarding the maximum speed
for your tyres.
You must on no account drive your car at more than the permissible maximum
speed for your winter tyres - risk of an accident resulting from tyre damage
and loss of control over your car.

Fit your summer tyres on again in good time since summer tyres offer you better
grip and handling on roads which are free of snow and ice as well as ar tempera-
tures below 7 °C - the braking distance is shorter, there is less tyre noise, tyre
wear is reduced and fuel consumption is reduced.
Please observe the various national legal requirements regarding tyres.
