Tires, Mounting With TPMS
The Tire Pressure Monitoring System (TPMS) specified within this information 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 Anti-lock Brake System (ABS). For more information on the ABS, refer to Description and Operation .
- Pay attention to the instructions for warming-up cold tires to the minimum mounting temperature, refer to ASSEMBLY REQUIREMENTS .
- Pay attention to the safety precautions and conditions, refer to SAFETY PRECAUTIONS AND CONDITIONS FOR REMOVING AND INSTALLING TIRES, WHEELS WITH TIRE PRESSURE MONITORING SYSTEM .
-- 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 the direction of the -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 max. 3.3 bar (48 psi) of spring pressure.
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 max. 3.3 bar (48 psi) of spring 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, refer to TIGHTENING SPECIFICATION FOR MOUNTING WHEELS .
