Tire, With Run-Flat Tires
Tire, with Run-Flat Tires
Tire, Pressing Off
CAUTION!
• Note the safety precautions. Refer to => [ Run-Flat Tire Safety Precautions ] Run-Flat Tire Safety Precautions.
- 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 around circumference while thoroughly applying tire mounting paste between tire and rim flange - arrow -.
Tires, Dismounting
CAUTION!
• Note the safety precautions. Refer to => [ Run-Flat Tire Safety Precautions ] Run-Flat Tire 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 sensor, otherwise the mounting head will damage the tire pressure sensor.
- Position mounting head - 1 - in vicinity of tire valve/tire pressure sensor so that tire iron can be put on approximately 30° next to tire valve/tire pressure sensor - 2 -.
- Install press holders - 3 - on disc wheel opposite the mounting head - 1 -.
- Now pry tire bead over mounting finger on mounting head using tire iron and remove tire iron again.
- 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 sensor, otherwise the mounting head will damage the tire pressure sensor.
- Position mounting head - 1 - in vicinity of tire valve/tire pressure sensor so that tire iron can be put on approximately 30° 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.
• Check tire pressure sensor for loose or damaged parts. If threaded connections are loose, union nut, valve insert, seal, sealing washer and valve cap must be replaced by new parts from repair set.
• If tire pressure sensor is damaged, then it must be replaced completely. Refer to => [ Tire Pressure Sensor ] Tire Pressure Sensor.
Tires, Mounting
CAUTION!
• Pay attention to the instructions for warming-up cold tires to the minimum mounting temperature. Refer to => [ Run-Flat Tires Assembly Requirements ] Run-Flat Tires Assembly Requirements.
• Note the safety precautions. Refer to => [ Run-Flat Tire Safety Precautions ] Run-Flat Tire 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 tire bead fits correctly on mounting head and let mounting device run 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 tire to an inflation pressure of maximum 3.3 bar (spring 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 tire to an inflation pressure of maximum 3.3 bar (spring pressure).
- If tire beads make contact on bead seat without problems, then increase inflation pressure to 4 bar 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. Refer to => [ Tightening Specification for Mounting Wheels ] Tightening Specification For Mounting Wheels.
