Audi Q3: Tires, Mounting, Run-Flat Tires

  Caution

It is mandatory for run-flat tires to have a tire pressure monitoring system in the vehicle.

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

  WARNING

The minimum mounting temperature for a tire may not be below 21ºC (70ºF) or above 30℃. (86 ºF)

  Note

  • Be careful not to scratch off the glued- on wheel trim on these rims.
  • The surface of the wheel trim is very sensitive.
  • The rim will have be replaced if the wheel trim is damaged.
  • The wheel trim cannot be replaced.

Audi Q3. A44-10265

- 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.

  WARNING

The minimum mounting temperature for a tire may not be below 21℃ or above 30℃.

  Note

  • Be careful not to scratch off the glued- on wheel trim on these rims.
  • The surface of the wheel trim is very sensitive.
  • The rim will have be replaced if the wheel trim is damaged.

Audi Q3. N44-10249

  • The wheel trim cannot be replaced.

- 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-.

Audi Q3. N44-10250

- 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 the tire bead is seated correctly on the mounting head and run the mounting machine clockwise.

Audi Q3. N44-10251

- 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 the tire to a inflation pressure of maximum 3.3 bar (bounce 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 the tire to a inflation pressure of maximum 3.3 bar (bounce pressure).

- If tire beads make contact on bead seat without problems, then increase inflation pressure to 4 bar to "settle" tire.

- Screw on a new valve insert and fill the tires to the specified pressure.

- Then balance wheel.

- Install the wheel and tighten it to tightening specification.
