Audi Q3: Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten easily.
Rims
Rims with a bolted rim ring or with bolted wheel covers consist of multiple pieces. These components were bolted together using special bolts and a special procedure. You must not repair or disassemble them.
WARNING
Wheel bolts that are tightened or repaired incorrectly can become loose and result in loss of vehicle control, which increases the risk of an accident. For the correct tightening specification.
- Always keep the wheel bolts and the threads in the wheel hub clean and free of grease.
- Only use wheel bolts that fit the rim.
- Always have damaged rims repaired by an authorized Audi dealer or authorized Audi Service Facility. Never repair or disassemble rims yourself, because this increases the risk of an accident.
Winter tires
Winter tires significantly improve the vehicle's handling when driving in winter conditions. Because of their construction (width, compound, tread pattern), summer tires provide less traction on ice and snow.
- Use winter tires on all four wheels.
- Only use winter tires that are approved for your vehicle.
- Please note that the maximum permitted speed may be lower with winter tires. An authorized Audi dealer or authorized Audi Service Facility can inform you about the maximum permitted speed for your tires.
- Check the tire pressure after installing wheels.
The effectiveness of winter tires is reduced greatly when the tread is worn down to a depth of 0.16 in (4 mm). The characteristics of winter tires also decrease greatly as the tire ages, regardless of the remaining tread.
For the sake of the environment
Reinstall summer tires at the appropriate time, because they provide better handling when roads are free of snow and ice. Summer tires cause less road noise, tire wear, and fuel consumption.
Tips
You can also use all season tires instead of
winter tires. Please note that in some countries
where winter tires are required, only
winter tires with the .png)

permitted.
