Volkswagen Touran Service Manual: Tires, Mounting, Run-Flat Tires and Ultra High Performance Tires

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.

Bring the tires to the mounting temperature. Refer to → Chapter "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 new tire valve with Valve Fitting Tool -VAS6459-.

Coat 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.

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

Let the tire dismounting/mounting machine run clockwise until the mounting head is in front of the tire valve or the tire pressure monitoring sensor -arrow-. Slide the lower tire bead over the rim flange.

Turn the rim until the tire valve of the tire pressure monitoring sensor -1- aligns with the mounting head -2-.

Install the hold-down device -3- on the rim.

Let the tire dismounting/mounting machine run clockwise until the mounting head is in front of the tire valve or the tire pressure monitoring sensor. Slide the upper tire bead over the rim flange.

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

Caution

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

Never set the spring pressure over 3.3 bar (47.86 psi).

Inflate the tire to maximum pressure of 3.3 bar (47.86 psi) (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 (58 psi).

If the tire bead does not make complete contact with the bead seat, dismount the tire and mount it again. Refer to → Chapter "Tires, Dismounting, Run-Flat Tires and Ultra High Performance Tires".

Turn the valve insert.

Fill the tire with the specified tire pressure.

Balance the tire. Refer to → Chapter "Wheel, Balancing".

Note Avoid strong braking or acceleration maneuvers during the first 100 to 200 km (62.13 to 124.27 miles). Otherwise due to the tire mounting paste the tires can distort on the rim.
