Tires: Service and Repair
Replacing a tire (Run Flat)
Read the fitting machine manufacturer's operating instructions.
It is absolutely essential to ensure that all the equipment is in perfect condition and to eliminate the risk of damage to the disk wheel and the tire.
Note: For approved wheel/tire combinations, tire makes and special equipment, refer to Service Information or Commercial Service Data CD
Caution: To avoid damaging rims, use only approved tire irons with plastic protectors.
Use only approved tire mounting paste.
Tire removal with a fitting machine:
Pull off balance weights on rim and clean rim to remove large pieces of dirt.
Unscrew valve insert, release air.
If tire beads are tightly seated, first release the tire slowly and carefully with the unseating tool at several points on the wheel before the actual unseating procedure.
Caution: Gap between unseating tool and rim flange must not exceed 2 centimeters.
Apply a generous coating of tire mounting paste between tire and rim flange.
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 mounting paste between rim flange and tire bead in so doing.
Grip wheel with outer side facing upwards on fitting machine.
Position special tool 36 1 094 and special tool 36 1 095 as shown on rim flange.
Slide special tool 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 tool 36 1 091/36 1 092 with connecting cable of special tool 36 1 095.
Slide a second special tool 36 1 091/36 1 092 on right next to first special tool 36 1 091/36 1 092 between tire bead and rim flange.
Lever tire bead over rim flange.
Remove first special tool 36 1 091/36 1 092 and and slide on right next to second special tool 36 1 091/36 1 092 between tire bead and rim flange and lever tire bead over rim flange.
Repeat this procedure in clockwise direction until tire bead is located fully over rim flange.
Swivel or tilt fitting head into position and allow it to snap into place.
Lever lower bead with tire iron over mounting finger.
Run fitting machine forwards clockwise until tire is completely detached from rim.
Release lock and tilt or swivel fitting head back. Unclamp and clean rim. Replace valve.
Mounting tires with a mounting machine:
Clamp rim on mounting machine.
Apply a generous coating of tire mounting paste between rim flange and tire bead.
Push tire with lower bead partially over rim flange.
Valve 10 cm to right of fitting head.
Swivel or tilt fitting head into position and lock into place. Check fitting head setting, readjust and clamp down if necessary.
Press tire by hand under fitting head.
Make sure tire bead is correctly seated on fitting head.
Allow fitting machine to run forwards gradually in clockwise direction.
Lower tire bead will drop into well.
Position special tool 361 093 as shown on rim.
Position special tool 361 094 as shown on rim flange.
Make sure tire bead is correctly seated on fitting head.
Allow fitting machine to run forwards gradually in clockwise direction.
In so doing, position special tool 36 1 095 as shown on rim flange.
Allow fitting machine to continue running in clockwise direction.
The tire bead jumps into the rim well.
After completing fitting, first release clamping claws.
Inflate with air (without valve insert).
Increase pressure up to 3.3 bar (330 kPa) in stages (jumping pressure). Do not increase pressure further if tire bead fails to slip fully all over at rim edge.
Release air, force off tire bead again.
Coat rim flange again with tire mounting paste.
Reinflate tire to 3.3 bar.
If tire beads rest perfectly on rim shoulders, increase inflation pressure to max. 4.0 bar to "seat" tire.
Screw in valve and correct tire pressure.
