Tire, With Tire Pressure Monitoring System
Tire, with Tire Pressure Monitoring System
Tire, Pressing Off
CAUTION!
• Pay attention to the safety precautions and conditions. Refer to => [ Tire Pressure Monitoring System Safety Precautions ] Service 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!
• Pay attention to the safety precautions and conditions. Refer to => [ Tire Pressure Monitoring System Safety Precautions ] Service Precautions.
• Mounting head must not be located in area - a - of tire valve/tire pressure sensor, otherwise the mounting head will damage the tire pressure sensor.
Removing Tires
- Turn the wheel on tire mounting device so that valve/tire pressure sensor is in front of mounting head.
- Position mounting head 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.
- 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.
- Turn the wheel on tire mounting device so that valve/tire pressure sensor is in front of mounting head.
• 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 safety precautions and conditions. refer to => [ Tire Pressure Monitoring System Safety Precautions ] Service Precautions.
• When changing a tire, it is recommended to change the tire pressure sensor seals at the same time.
- Coat rim flanges, tire beads and inside of upper tire beads thoroughly with tire mounting paste.
- Install the inner side of the tire first
- Turn the disc wheel on tire mounting device so that valve/tire pressure sensor- arrow - is opposite to the mounting head.
- Push the tires between the tire valve/tire pressure sensor and the mounting head into the bed - direction of arrow -.
- Let the tire dismounting/mounting machine run clockwise.
- Mounting of the lower bead ends before the tire valve/tire pressure sensor 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.
- 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 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.
- 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.
