Fitting
the 17 Inch Wheels (Cup Design) to the Vehicle
On the 17" Cup Design wheels, the valve
(No. 1) and the locking wheel nut cannot be
arranged on the same side (as on previous
models).
For correct installation, the valve (No. 1)
must face the color-coded stud (No. 2).
Be sure to fit the locking wheel nut to the
color-coded stud (Nr. 2).
If required, mark the wheel stud located op-
posite the valve before removing the wheel.
For stationary balancing of the wheels (with
step rings), turn the wheel in such a manner
that the valve points to the bottom. Tighten
the wheel in this position.
After balancing, mount the wheel to the ve-
hicle in an identical position (valve faces to
the bottom / color-coded wheel stud and lock-
ing wheel nut located on top).
Important note
Fitting (and tightening) procedures of all
other wheel types (16lnch Deslgn 90 etc.)
for stationary balancing remain unchanged.
This means: Coded stud, valve and locking
wheel nut are located on the same side. When
tightening, valve must point up (same position
as on balancing equipment).
It is recommended to add an extra refer-
enceto the modified assembly in the "Wheel
balancing and General notes on fitting tires"
chapter.
