Expert Buying Guide for 2018 Audi S8
For your 2018 Audi S8, the 5x112 bolt pattern and 66.5mm center bore are critical. Aftermarket wheels often have a larger center bore, requiring hub-centric rings to prevent vibrations and ensure proper load transfer. Offset must stay within 30-45mm; deviations risk rubbing or clearance issues with brakes and suspension. Always use lug nuts with 14x1.5 thread pitch and the correct seat type—Audi typically uses ball seats, but verify your wheels. Improper lug nut seating can lead to wheel loss. Stick to OEM or quality aftermarket wheels from 2001–2024 Audi S8 models for guaranteed compatibility.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts after 50-100 miles of driving to account for settling.
- ✅ Avoid using universal fit wheels without hub-centric rings; they can cause steering wheel vibration.
- ✅ Check brake caliper clearance when changing offset, especially with aftermarket big brake kits.
- ⚠️ Confirm bolt pattern carefully. 5x112 is often confused with other common 5-lug patterns.
- ⚠️ This fitment uses a wide offset range. Check brake clearance and fender clearance before buying wheels.
- ⚠️ Torque lugs in a star pattern to 100 ft-lbs (135 Nm), then re-check torque after 50-100 km (30-60 miles).

2018 Audi S8 — Frequently Asked Questions
What is the bolt pattern for a 2018 Audi S8?
The 2018 Audi S8 uses a 5x112 bolt pattern (also called lug pattern or PCD). The center bore is 66.5mm and the offset is 30-45mm.
What other years of Audi S8 have the same bolt pattern as the 2018?
The Audi S8 uses the 5x112 pattern from 2001 through 2024. Wheels from any of these model years are dimensionally compatible with the 2018, provided the offset and center bore also match.
Why is matching the 66.5mm center bore important for the 2018 S8?
The 66.5mm center bore ensures the wheel is perfectly centered on the hub. If the wheel is lug-centric instead of hub-centric, you may experience steering wheel vibration at highway speeds.
What does 30-45mm offset mean for the 2018 S8?
An offset of 30-45mm means the wheel's mounting surface is 30-45mm away from its centerline. Changing this value drastically can affect suspension geometry and wheel bearing wear on your Audi.
Can I use spacers on my 2018 Audi S8?
Yes, but ensure the wheel spacers match the 5x112 bolt pattern and 66.5mm center bore. Also verify that you have enough thread engagement for your 14x1.5 hardware.
Will wheels from another Audi fit my 2018 S8?
Only if they share the exact same 5x112 bolt pattern, a compatible offset, and a center bore equal to or larger than 66.5mm.
