First read and observe the introductory information and safety warnings 
The design of the wheel bolts is matched to the rims. If different rims are fitted, the correct wheel bolts with the right length and correctly shaped bolt heads must be used. This ensures that wheels are fitted securely and that the brake system works properly   .
For technical reasons, it is not generally possible to use the wheels from other vehicles. This can also apply to wheels of the same vehicle type.
The tyres and rims approved by Volkswagen are specifically matched to the characteristics of the vehicle and make a major contribution to good road holding and safe handling.
Wheel bolts
Wheel bolts must always be tightened with the correct tightening torque   .
Rims with bolted-on rings
Rims with bolted-on rings consist of several components. These components are fastened using special bolts and special fastening technology. This ensures that the wheel functions properly, does not leak, remains safe and runs true. For this reason, damaged rims should be replaced. They may only be repaired by a qualified workshop. Volkswagen recommends using a Volkswagen dealership for this purpose  .
Rims with bolted-on trims
Rims may have removable trims that are attached to the rim with self-locking bolts. Damaged trims may only be repaired by a qualified workshop. Volkswagen recommends using a Volkswagen dealership for this purpose  .
