Do not remove wheel sensor for this.


Do not use compressed air, solvents or

detergents to clean the wheel sensor. Wipe

off dirt with a clean, lint-free cloth only.

Do not retighten the female torx bolt and

Mounting

10
Moisten rim flange and tire beads with soapy

water and align assembly head at a small

distance (X, Y) to the disk wheel

Only use soapy water for fitting and

removing tires.

11
Place tire obliquely on the rim and pull on

over the rim flange using the tire installer


Position wheels with wheel sensors so

that the wheel sensor is approximately 180°

opposite the mounting head.

Do not apply compressive force to the wheel
sensor otherwise it will be damaged.


Observe the running direction on tires with

specified running direction.


Put as little stress as possible on bead

area.

12
Align the match points of the tire and disk

wheel with each other and remove the disk

wheel with tire from the tire mounting device

13
Inflate tires without valve element up to max.

3 bar

Do
not
unscrew valve element on disk

wheels with tire pressure monitor sensor.

The tire must slide evenly over the safety

shoulders of the disk wheel, otherwise coat

the tire beads with soapy water again.

14
Screw the valve element into the valve (43g)

and adjust the tire inflation pressure to the

specified value

Observe the tire pressure information in

the fuel filler flap of the vehicle.

1
Check inside and outside of wheel for dirt and clean wheel if necessary.

2
Check contact surface of rim for dirt and clean if necessary.

3
Check centering, spherical caps and rim flanges for damage. The spherical caps must be

free of grease.

Light-alloy rims

4
The rim flanges on light-alloy rims may exhibit increased levels of wear under the following

conditions:

High loads, operation with a trailer, insufficient tire inflation pressure, use of non-approved

tire makes or versions, contamination with dirt, sand and road salt.

5
The wear (X) must be no more than 1 mm.
