Audi S1 Tyre & Wheel Fitment Guide

The Audi S1 is a compact performance hatch powered by Audi’s legendary quattro AWD system. With its aggressive stance and turbocharged performance, choosing the correct tyre and wheel setup is critical for maintaining grip, handling, and ride quality.

At Autosport Tyreworld, we specialise in performance tyre packages and precision wheel fitments tailored specifically for vehicles like the Audi S1.

Factory Tyre Sizes (Audi S1 8X – 2014–2018)

Standard Factory Fitment

• 215/40R17

Optional / Upgraded Factory Fitment

• 225/35R18

These sizes are engineered for optimal balance between ride comfort, handling precision, and quattro traction.

Factory Wheel Specifications

Centre Bore Details

• Centre Bore: 57.1 mm
  Audi uses a hub-centric design, meaning the wheel must match the centre bore precisely for vibration-free driving.

If using aftermarket wheels, always ensure:

• Correct centre bore, or

• Use hub-centric rings to maintain proper fitment

Wheel Torque Specifications

• Wheel Bolt Torque: 120 Nm

Correct torque is essential for safety and to prevent:

• Warped brake discs

• Uneven load distribution

• Wheel loosening

Always torque using a calibrated torque wrench.
