Wheel Changing
Warm Up Cold Tires to the Minimum Mounting Temperature
Note
This applies also to ultra high performance tires (height- / width
ration smaller/same 45% and speed rating symbol larger than/
same as V).
WARNING
The minimum mounting temperature for a tire should be be‐
tween 15 °C and 30 °C (59 and 86 °F) in the center of the tire.
• For injury-free mounting, the upper sidewall and the upper
bead inside must be minimum 15 °C (59 °F).
• The internal temperature is called the core temperature.
• Rubber is a poor heat conductor, and for this reason, a cold
tire must exposed to a temperature controlled environment
until the inner rubber layers have warmed up to at least 15 °C
(59 °F).
• The temperature of the tire surface during the warm-up phase
should not be considered as the temperature on the inside of
the tire.
• So that the cold tires warm up quickly, never stack them one
on top of the other. They should be stored separated from each
other so that the warm air can “circulate” around them.
• Never use a room heater or a hot air gun to warm up tires
because the surface temperature will heat up very quickly to
a critical temperature.
• Using warm water or warm air (maximum 50 °C (122 °F)) is
the only way to warm a tire safely.
• If cold tires (below 0 °C (32 °F)) are brought into a warm en‐
vironment (above 0 °C), then a layer of ice will form on the
surface of the tire. This layer, caused by the condensation of
the humidity, shows that the tire has begun to absorb the
warmth.
• Once the layer of ice starts to melt, wipe up the water with a
rag so that the warming up process will not be slowed down.
Warm-Up Time
♦ Tires warmer than 0 °C (32 °F) must be stored at minimum 19
°C (66.2 °F) for at least 2 hours.
♦ Tires colder than 0 °C (32 °F) must be stored at minimum 19
°C (66.2 °F) for at least 2.5 hours.
Recommendations:
♦ If possible, let the tires stand in the shop for 1 day before
mounting them
♦ Store them on an insulated surface, a wood pallet or some‐
thing similar.
♦ Position the tires so that they can be “surrounded” by the warm
air.
♦ Wipe off the sweat
♦ Never heat the tires with a room heater or a hot air gun!

Wheel Changing Instructions
WARNING
The secure seating of the wheel bolts and the wheels is only
ensured if the instructions and checks below are followed.
Note
After removing or installing one or multiple tires, the tire pressure
monitoring system must be calibrated for vehicles with tire pres‐
sure monitoring system. Refer to
.
– Make sure the contact surfaces -arrows- on the brake disc are
free from corrosion and dirt.
– Make sure the contact surfaces -arrow- on the brake disc cen‐
ter seat are free of corrosion and dirt.
– Make sure the contact surface -arrow- on the wheel inner side
(rim) as well as the central seat in the rim is free of corrosion
and dirt.
– The spherical caps
*
in the wheel bolt openings and the wheel
bolt threads must likewise be free of corrosion, dirt, oil or
grease.
*
The spherical cap is the curved surface of a section of a sphere.
– Check whether the wheel bolts can be easily screwed in by
hand. The threads of the wheel bolts must not touch the holes
in the brake disc -arrow-.
If the thread of the wheel bolt touches the hole -arrow-, turn the
brake disc relative to the wheel accordingly.
Remove Any Dirt or Corrosion if Necessary
♦ Oil or grease from the contact surfaces
♦ Oil or grease from the threads on the wheel hub
♦ Oil or grease from the threads on the wheel bolts
WARNING
Heavily corroded, difficult to turn or damaged wheel bolts must
be replaced.
1.5.4
Wheel Changing and Wheel Installation
– Coat the wheel centering seat with protective material. Refer
to
⇒ “1.5.1 Wheel Changing, Protecting Wheel Centering Seat
1 - When mounting a wheel, tighten all wheel bolts uniformly by
hand.
2 - Tighten the wheel bolts diagonally to approximately 30 Nm.
3 - Lower the vehicle to the ground. Tighten all the wheel bolts
diagonally to the tightening specification using the torque
wrench. Refer to
⇒ “1.1 Wheel Bolt Tightening Specifications”, page 286
WARNING
Do not use an impact wrench to install the wheel bolts.
1.5.5
Wheel Changing, Position of Anti-Theft
Wheel Bolts on Steel Wheels
Caution
It is absolutely necessary to maintain the position of the anti-
theft wheels bolts to the tire valve on steel wheels.
The anti-theft wheel bolt must be installed either to the right or to
the left -arrows- of the valve -1- on steel wheels.
The decorative wheel hubcap can be installed on the steel wheel
securely only when the anti-theft wheel bolt is installed in this po‐
sition.
1.6
Tire Sealant, Disposing
♦ Tire sealant or residue from it must not be mixed with other
wastes/fluids
♦ Accumulating fluid residue from tire sealant must be collected
and placed in a plastic container. The plastic containers can
be sent for recycling together with the tire sets (if the expiration
date has passed).
♦ The return or recycling can take place using the existing shop
disposal systems
♦ Check with the company responsible for trash pickup for the
dealership.
1.7
Vehicles with Tire Mobility Kit
1.7.1
Vehicles with Tire Mobility Kit, Golf
Depending on the vehicle equipment, the vehicles are equipped
with a tire mobility kit.
The tire mobility kit is located in the tool compartment -3- in the
luggage compartment on the right side.
The tire mobility kit contains a bottle of tire sealant -1- and a com‐
pressor -2-.
Tire sealant in the bottle has a limited storage life.
Therefore the minimum shelf life date -arrow- is marked on the
bottle -1-.
Replace tire sealant when minimum shelf life date has been
reached (tire sealant must not be older than 4 years).
If the bottle was opened, for example, for a punctured tire, it must
also be replaced.
Observe the disposal regulations. Refer to
⇒ “1.6 Tire Sealant, Disposing”, page 292
1.7.2
Vehicles with Tire Mobility Kit, Golf Wag‐
on
Depending on the vehicle equipment, the vehicles are equipped
