Tires, Dismounting With Run Flat Tires

CAUTION:

Pay attention to the safety precautions and conditions, refer to SAFETY PRECAUTIONS AND CONDITIONS FOR REMOVING AND INSTALLING TIRES, WHEELS WITH TIRE PRESSURE MONITORING SYSTEM .

-- Release air from tires, unscrew the nickel-coated valve insert to do so.

-- When pressing off tire on a tire dismounting/mounting machine with press-off blade, always make sure that tire valve/tire pressure sensor -arrow- is located opposite the press-off blade -1-.

CAUTION: Mounting head -1- must not be located in area -a- of tire valve/tire pressure sensor, otherwise the mounting head will damage the tire pressure sensor.

-- Position mounting head -1- in vicinity of tire valve/tire pressure sensor so that tire iron can be put on approximately 30° next to tire valve/tire pressure sensor -2-.

-- Install press holders -3- on disc wheel opposite the mounting head -1-.

-- Now pry tire bead over mounting finger on mounting head using tire iron and remove tire iron again.

-- Let the tire dismounting/mounting machine run clockwise until upper bead lies completely above the rim flange.

CAUTION: Mounting head -1- must not be located in area -a- of tire valve/tire pressure sensor, otherwise the mounting head will damage the tire pressure sensor.

-- Position mounting head -1- in vicinity of tire valve/tire pressure sensor so that tire iron can be put on approximately 30° next to tire valve/tire pressure sensor -2-.

-- Now pry tire bead over mounting finger of mounting head using tire iron -3-.

-- In addition, insert a plastic mounting lever -4-.

-- Remove tire iron -3- again.

-- Using plastic mounting lever -1-, hold bead in place over the rim flange from outside and let tire mounting device run clockwise until tire has been pulled off completely from disc wheel.
