In the 2018 Audi Q5, the wheels are secured with lug bolts rather than lug nuts. The standard fastener size is M14 x 1.5 with a 60-degree conical seat, and the bolt head typically requires a 17 mm socket.
Wheel fastener basics for the 2018 Q5
Understanding these specifications helps you perform wheel changes, replace damaged fasteners, or order the correct parts. The Q5 uses a five-bolt pattern on a 112 mm circle, and Audi specifies the correct size and seat to ensure proper seating and torque.
Key specifications for factory wheel fasteners:
- Thread size: M14 x 1.5
- Seat type: 60-degree conical seat
- Bolt pattern: 5 bolts on a 112 mm circle (5x112)
- Hardware type: Lug bolts (not lug nuts)
- Socket size for removal/torque: 17 mm
- Typical torque specification: approximately 110–125 Nm (verify in the owner's manual or service data for your exact wheel and trim)
These guidelines apply to stock wheels. If you replace wheels with aftermarket options, confirm the fastener size and torque, as some setups use different thread sizes or seat types.
Additional considerations
Always use the correct fasteners specified for your wheel and torque them to the vehicle’s recommended specification after installing a wheel. Use a calibrated torque wrench and re-torque after about 50–100 miles (80–160 kilometers) as part of standard wheel maintenance.
Summary
The 2018 Audi Q5 uses lug bolts sized M14 x 1.5 with a 60-degree conical seat, arranged in a 5x112 bolt pattern. The bolt head typically requires a 17 mm socket, with a torque spec generally around 110–125 Nm. Always confirm exact specifications for your particular wheel setup in the owner's manual or Audi service data, especially if you’re using aftermarket wheels.
