Fitting run-flat tyres   Caution t  Note conditions for minimum fitting temperature → Chapter t  Observe safety notes → Chapter –  Apply a generous amount of tyre fitting lubricant to wheel flanges, tyre beads and area inside upper tyre beads.   Note t  On rims with bonded wheel trims, take care not to scratch the wheel trims. t  Wheel trims have a very sensitive surface. t  If a wheel trim is damaged, the rim must be renewed.

t  The wheel trim cannot be renewed.

–  Turn wheel on tyre fitting unit so that tyre valve/tyre pressure sensor-1- is on opposite side to head of fitting unit -2-. –  Run tyre fitting unit in clockwise direction.   Note t  On rims with bonded wheel trims, take care not to scratch the wheel trims. t  Wheel trims have a very sensitive surface. t  If a wheel trim is damaged, the rim must be renewed.

t  The wheel trim cannot be renewed.

–  Stop fitting lower bead before tyre valve/tyre pressure sensor-arrow- reaches tool; otherwise tyre pressure sensor will be damaged. Tyre bead will now slip over wheel flange. Make sure that tyre fitting unit stops turning wheel before tyre valve/tyre pressure sensor-arrow- reaches head of fitting unit.

–  Turn wheel on tyre fitting unit so that tyre valve/tyre pressure sensor-1- is on opposite side to head of fitting unit -2-. –  Attach retainers -3- to wheel. –  Ensure that tyre bead is seated correctly on head of fitting unit and run tyre fitting unit in clockwise direction.

–  Stop fitting upper bead before tyre valve/tyre pressure sensor-arrow- reaches tool; otherwise tyre pressure sensor will be damaged. Tyre bead will now slip over wheel flange. Make sure that tyre fitting unit stops turning wheel before tyre valve/tyre pressure sensor-arrow- reaches head of fitting unit. –  Remove retainers from wheel flange. –  Inflate tyre to max. 3.3 bar (bead seating pressure).   Caution Do not continue inflating the tyre if the beads do not make full contact at the edge of the wheel. The tyre or wheel will otherwise be damaged. –  If tyre beads do not make full contact at edge of wheel, release air from tyre, press off tyre bead again and apply another generous coating of tyre fitting lubricant to wheel flange. –  Inflate tyre to max. 3.3 bar (bead seating pressure). –  Once tyre beads have made proper contact with bead seats, increase inflation pressure to 4 bar to seat the tyre. –  Screw in a new valve core and inflate tyre to specified pressure. –  Then balance the wheel. –  Fit wheel to vehicle and tighten to specified torque.
