36 12 005 Replacing A Runflat Tire
Special tools required:
Follow the tire fitting machine manufacturer's operating instructions.
It is absolutely essential to ensure that the equipment is in proper working condition and that there is no damage to the disc wheel and tire.
After completion of work, BALANCE WHEELS .
Only approved and certified tire fitting machines may be used for installing run-flat tires and/or UHP tires!
Please refer to the operating instructions of the respective tire fitting machine for details of the exact fitting procedure.
Use only BMW-approved plastic-covered mounting levers!
Use only BMW-approved tire-fitting paste.
These two holes are production-related!
The presence of these two little holes in the tread pattern does not represent a fault and does not affect the performance and the efficiency of the tires in any way!
- Item (1) Marking denoting BMW-approved tires. Ensure that only BMW-approved tires are fitted.
- Item (2 ) RSC is the abbreviation for R unflat S ystem C omponent (runflat tires).
- Item (3) Outside. The tire must be fitted so that the wording Outside is always situated on the outside of the rim.
The arrow on the tire must point in the direction of travel for each wheel!
tire removal with a tire fitting machine:
Do not position pressing-off tool in area of valve (damage to wheel pressure sensor). Turn wheel through 180° and position pressing-off tool on opposite side.
Pull off balance weights on wheel rim and clean rim to remove large pieces of dirt.
Unscrew valve insert, release air.
If tire beads are stuck, first release the tire with the pressing-off tool at several points of the wheel before actually pressing off, applying tire-fitting paste between the tire and the rim flange. Only then press off the tire completely.
Force off inner side of wheel, inserting special tool 36 1 098 between rim flange and tire bead in so doing.
Force off outer side of wheel, applying a generous coating of tire-fitting paste between rim flange and tire bead in so doing.
Grip wheel with outer side facing upwards on tire fitting machine.
Position special tool 36 1 094 and special tool 36 1 095 in as shown on rim flange.
Fit special tools 36 1 091 /36 1 092 between tire bead and rim flange, move into position shown and lever tire bead over rim flange.
Secure special tools 36 1 091 /36 1 092 with the connecting cable of special tool 36 1 095 .
Move a second special tool 36 1 091 /36 1 092 to the right next to the first special tool 36 1 091 /36 1 092 between tire bead and rim flange.
Lever tire bead over rim flange.
Remove the first special tool 36 1 091 /36 1 092 and move it to the right next to the second special tool 36 1 091 /36 1 092 between tire bead and rim flange and thereby lever tire bead over the rim flange.
Continue this procedure in clockwise direction until tire bead is resting fully over rim flange.
Swivel or tilt mounting head into position and allow it to snap into place.
Lever lower bead with mounting lever over mounting finger.
Run tire fitting machine forwards clockwise until tire is completely detached from wheel rim.
Release lock and tilt or swivel mounting head back.
Unclamp and clean rim.
Replace valve.
Coat lower tire bead (1) on outer side with plenty of tire-fitting paste .
Coat upper tire bead (2) on inner and outer side with plenty of tire-fitting paste .
tire fitting with a tire fitting machine:
Clamp wheel rim on tire fitting machine.
Push tire with lower bead partially over rim flange.
Valve 10 cm to right of mounting head.
Swivel or tilt mounting head into position and lock into place.
Check fitting of mounting head, readjust and clamp down if necessary.
Press tire by hand under mounting head.
Make sure lower tire bead is correctly seated on mounting head.
Allow tire fitting machine to run forwards gradually in clockwise direction.
Lower tire bead will drop into well.
Position special tool 36 1 093 , 36 1 094 on the wheel rim in the manner shown.
Make sure upper tire bead is correctly seated on mounting head.
Allow tire fitting machine to run forwards gradually in clockwise direction.
In so doing, position special tool 36 1 095 as shown on rim flange.
Allow tire fitting machine to continue running in clockwise direction.
Upper tire bead jumps into the wheel rim center.
Observe national/country-specific regulations.
After completing fitting, first release clamping claws.
Inflate with air (without valve insert).
Increase pressure up to 3.3 bar (330 kPA) in stages (fitting pressure).
If the tire bead does not slip fully past the rim edge all round, do not under any circumstance increase the pressure.
Release air, force off tire bead again.
Coat rim flange again with tire-fitting paste .
Inflate tire again up to 3.3 bar.
When tire beads are resting perfectly on rim shoulders, increase tire pressure to max. 4.0 bar to "settle" tire.
Screw in valve insert and correct tire pressure.
After completion of work, BALANCE WHEELS .
The assembly paste can cause the tire to turn on the wheel rim and give rise to imbalance.
