Work descriptions
- Check to make sure that windshield wiper system is not
juddering.
Checking tire condition, tread wear pattern ,
filling pressure and tread depth
Note:
For reasons of safety only tires of same type and
n
tread pattern should be fitted on a vehicle!
Note:
Vehicle must be equipped with tires of same make.
n
Otherwise, This can cause damage because viscous
clutch would unnecessarily increase ratio of rear final
drive due to rising RPM difference of both axles.
However, different tread depths of front axle and rear
n
axle tires, e.g. due to wear, is harmless. It is
recommended, however, to mount tires with greater
tread depth in front.
If front wheels are more strongly worn out than rear
n
wheels, they have a smaller rolling circumference and
turn therefore faster.
Thus tensions in drivetrain rise and tires wear faster.

Inspection service:
- Check tires for scuffing, one sided wear, porous side
walls, cuts and fractures. It is essential that detected
defects are communicated to customer!
