Care and maintenance of alloy wheel rims
Regular care is required to maintain the decorative appearance of alloy wheels over a long period of time.
In particular road salt and dust from brake abrasion must be thoroughly washed off every 2 weeks; otherwise the finish of the alloy wheel will suffer.
Cleaning agents:
^
Plain water or water with soft soap
^
Water and essence of vinegar
^
Alloy wheel cleansers without acids or strong solvents
Do not exceed the soaking time of the cleaning agent.
The shorter the recommended soaking time, the stronger and more aggressive the cleaning agent.
If the finish is damaged, for example by stones, the damage must be repaired as quickly as possible.
Removing adhesive residue from glued balance weights on alloy rims:
^
Strong solvents and acids attack the finish on alloy wheels and the surface of the wheel becomes matt and milky. These substances should not be
used.
^
To remove adhesive residue on alloy wheels, use alloy cleansers or a oil-based cleanser. Do not exceed the soaking time of the cleaning agent.
^
After cleaning or removing adhesive residue from wheels, rinse them with water.
Rotating wheels:
^
Vehicles with front-wheel drive exhibit more tread wear on the front wheels due to the greater forces they have to transmit.
^
In order for all 4 wheels on the vehicle to have the same service life, we recommend rotating the front and rear wheels/tires.
^
Make sure that uni-directional tires are not reversed.
^
The longer the tire runs at one position, the more it wears at certain points. It is advisable to rotate the wheels at short intervals, for example every
5,000 km.
^
Diagonal rotation is possible only with non-directional tires. This wheel rotation method is especially advantageous in the case of heal-and-toe
wear. For more information on heal-and-toe wear, refer to
^
If heal-and-toe wear has already progressed and the tread is worn to more than 50%, only slight improvements would be achieved and rotation is
not recommended. The elasticity of the tread blocks declines and the heal-and-toe wear does not progress.
