The wheel bolts are designed to suit the rims on your car.
The wheel bolts are matched to the rims. When installing different wheels (for instance wheels with winter tyres) it is important to use the correct wheel bolts with the right length and correctly shaped bolt heads. This is essential for the secure fit of the wheels and for the proper function of the brake system.
Audi dealers have full information on the technical requirements when installing or changing tyres, rims or wheel trims.
The wheel bolts should be clean and turn easily.
A special adapter is required to turn the anti-theft wheel bolts.
