Volkswagen Tiguan Service and Repair Manual: Run-Flat Tires, Removing and Mounting
Safety Precautions
- Work for removing and mounting tires with emergency running
characteristics must only be performed by mechanics specially trained for
it.
- The special tools necessary must be in proper working order and not
damaged! Contact manufacturer of tire mounting device found in the shop
directly for suitable additional tools. Additional tools are offered as
recommended accessories for the tire mounting devices listed with VAS-
numbers.
- If necessary, use a mounting paste recommended by the tire manufacturer.
- The description of work procedure for removing and mounting may vary
depending on the device manufacturer and type of device.
- The following work procedure described explains the principal procedure
for removing and mounting tires with emergency running characteristics. It
is important to recognize run-flat tires before starting the removal and
mounting process as it will be different from the process used with standard
tires.
- Characteristics: These tires are identified with the following
abbreviations: DSST, Euforia, RFT, ROF, RSC, SSR or ZP. These abbreviations
are located on the tire flank behind tire designation of the respective tire
manufacturer.
- Always note the instructions and danger warnings identified in the
following description!
- Check whether Tire Pressure Sensor should be replaced (if equipped)
Refer to Vehicle Diagnostic Tester.
Note
- During removal and mounting work, make sure that no contact is made
between tires and the Tire Pressure Monitoring Sensor.
- When cleaning disc wheel (rim), the tire pressure monitoring sensor must
not come into contact with water or be blown with pressurized air.
Tires, Dismounting with TPMS
Note
- The Tire Pressure Monitoring System (TPMS) specified within this section
refers to the optional TPMS, which employs individual pressure sensors to
determine individual tire pressures.
- The base TPMS does not employ individual pressure sensors to determine
individual tire pressures, but instead is an integral part of the Antilock
Brake System (ABS). For more information on the ABS.
Caution
Pay attention to the safety precautions and conditions.
- Release air from tires, unscrew the nickel-coated valve insert to do so.
- When pressing off tire on a tire dismounting/mounting machine with
press-off blade, always make sure that tire valve/Tire Pressure Sensor-arrow-
is located opposite the press-off blade -1-.
Press-off blade must be applied at maximum 2 cm removed from rim flange.
- Remove balancing weights and coarse dirt from disc wheel.
- Press off both tire beads all the way around while thoroughly applying
tire mounting paste between the tire and rim flange
-arrow-.
Tires, Dismounting with Run Flat Tires
Caution
Note the safety precautions.
- Turn wheel on tire mounting device so that tire valve/Tire Pressure
Sensor-2- stands in front of mounting head
-1-.
Caution
Mounting head -1- must not be located in area
-a- of tire valve/tire pressure monitoring sensor,
otherwise the mounting head will damage the Tire Pressure Monitoring Sensor.
- Position mounting head -1- in vicinity of
tire valve/Tire Pressure Sensor so that tire iron can be put on
approximately 30º next to tire valve/Tire Pressure Sensor-2-.
- Install press holders -3- on disc wheel
opposite the mounting head -1-.
- Now pry the tire bead over the mounting finger on the mounting head
using a tire iron and remove tire iron.
- Let the tire dismounting/mounting machine run clockwise until upper bead
lies completely above the rim flange.
This slides the press holders -1- against the
mounting head. This allows them to be removed again easily.
- Turn wheel on tire mounting device so that tire valve/Tire Pressure
Sensor-2- stands in front of mounting head
-1-.
Caution
Mounting head -1- must not be located in area
-a- of tire valve/tire pressure monitoring sensor,
otherwise the mounting head will damage the Tire Pressure Monitoring Sensor.
- Position mounting head -1- in vicinity of
tire valve/Tire Pressure Sensor so that tire iron can be put on
approximately 30º next to tire valve/Tire Pressure Sensor-2-.
- Now pry tire bead over mounting finger of mounting head using tire iron
-3-.
- In addition, insert a plastic mounting lever -4-.
- Remove tire iron -3- again.
- Using plastic mounting lever -1-, hold bead
in place over the rim flange from outside and let tire mounting device run
clockwise until tire has been pulled off completely from disc wheel.
Note
- Check the Tire Pressure Sensor for loose or damaged parts. If threaded
connections are loose, the union nut, valve insert, seal, sealing washer and
valve cap must be replaced by new parts from the repair set. Refer to Parts
Catalog.
- If Tire Pressure Monitoring Sensor is damaged, then it must be replaced
completely.
Tires, Mounting with Run Flat Tires
Caution
- Pay attention to the instructions for warming-up cold tires to the
minimum mounting temperature.
- Note the safety precautions.
- Coat rim flanges, tire beads and inside of upper tire beads thoroughly
with tire mounting paste.
- Turn disc wheel on tire mounting device so that tire valve/Tire Pressure
Sensor-1- stands on opposite side of mounting
head -2-.
- Let the tire dismounting/mounting machine run clockwise.
- Mounting of the lower bead ends before the tire valve/Tire Pressure
Sensor-arrow- to prevent damage to Tire
Pressure Sensor.
Tire bead now slips over the rim flange. Wheel may be turned only as far
until mounting head is located just in front of tire valve/Tire Pressure Sensor-arrow-.
- Turn disc wheel on tire mounting device so that tire valve/Tire Pressure
Sensor-1- stands on opposite side of mounting
head -2-.
- Install press holders -3- on disc wheel.
- Make sure the tire bead is seated correctly on the mounting head and run
the mounting machine clockwise.
- Mounting of the upper bead ends before the tire valve/Tire Pressure
Sensor-arrow- to prevent damage to Tire
Pressure Sensor.
Tire bead now slips over the rim flange. Wheel may be turned only as far
until mounting head is located just in front of tire valve/Tire Pressure Sensor-arrow-.
- Remove press holders from rim flange.
- Inflate the tire to a inflation pressure of maximum 3.3 bar (47.8 psi)
(bounce pressure).
Caution
If tire beads do not make contact completely on disc wheel edge, pressure
must not be increased under any circumstances.
Pre-damage to tire or disc wheel would result.
- If tire beads do not make contact completely on disc wheel edge, then
release air, press off tire bead once more and coat rim flange thoroughly
again with tire mounting paste.
- Inflate the tire to a inflation pressure of maximum 3.3 bar (47.8 psi)
(bounce pressure).
- If tire beads make contact on bead seat without problems, then increase
inflation pressure to 4 bar (58 psi) to "settle"
tire.
- Install a new nickel-plated valve insert and fill the tire to the
specified pressure.
- Then balance wheel.
- Install wheel and tighten it to tightening specification.
