Tires, Mounting, Run-Flat Tires And Ultra High Performance Tires

WARNING: This page is about a different variant/trim than selected.

Only trained personnel can perform the assembly work on run-flat tires and ultra high performance tires.
If equipped check the tire pressure monitoring sensor with the vehicle diagnostic tester and if necessary replace.

-- Refer to TIRES, BRINGING TO MOUNTING TEMPERATURE

NOTE:

If equipped handle the glued-on wheel trim carefully. Surface slightly scratched.

Replace the damaged rim wheel trim.

-- Clean the rim.

-- Insert the new tire valve with the : VAS6459 .

-- Coat the rim flanges, tire beads and inside of upper tire beads thoroughly with tire mounting paste.

-- Place the inner side of the tire on the rim.

-- Turn the rim until the tire valve of the tire pressure monitoring sensor aligns with the mounting head.

-- Remove the hold-down device from the wheel rim flange.

CAUTION:

High spring pressure when filling tire.

Risk of injury from tire/rim fragments.

- Wear protective eyewear.

- Set the spring pressure up to the maximum of 3.3 bar.

CAUTION:

There is a risk of damaging the rim due to too high spring pressure.

- Set the spring pressure up to the maximum of 3.3 bar.

-- Inflate the tire to maximum pressure of 3.3 bar (spring pressure).

-- 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.

-- When the tire bead makes contact on the bead seat, increase the pressure to 4 bar.

-- If the tire bead does not make complete contact with the bead seat, dismount the tire and mount it again.

-- Turn the valve insert.

-- Fill the tire with the specified tire pressure.

-- Balance the tire.

NOTE:

Avoid strong braking or acceleration maneuvers during the first 100 to 200 km. Otherwise due to the tire mounting paste the tires can distort on the rim.
