How to Read Wheel Offset & Measurements

Use these two references before ordering: the left diagram shows where each spec (PCD, center bore, offset, width and diameter) is measured on the wheel; the right diagram shows how positive, zero and negative offset shift the wheel face relative to the hub centerline.

Audi S8 [UK] OE Wheel Specs

The 2022 Audi S8 [UK] (Sedan) uses a 5x112 bolt pattern with a 66.5mm center bore. Factory wheels are 21x9.0J F/R.

Why the factory spec works for most owners:

Balances ride comfort with everyday fuel efficiency
A widely used size in this segment, so tire and wheel availability stays strong
Keeps unsprung weight low for stable, predictable handling
Maintains clearance for the factory brake calipers and suspension components

Flush Fitment

For a flush look with minimal rubbing, F/R 22x10.0J ET25 is the recommended starting point on a stock or mildly lowered Audi S8 [UK].

Maximum Aggressive Fitment

F/R 22x10.5J ET20 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Real-World Reference Cases

The examples below are compiled from typical ANKUSI customer configurations and are labeled as reference cases, not individually verified real-world builds.

Case 1: Daily Driver (Factory-Style)

Profile: Everyday driving, prioritizes comfort and low running cost.

Setup: 21x9.0J ET35

Cost: ~$620

Outcome: Minimal visual change, ride and fuel economy essentially unaffected.

Case 2: Balanced Enthusiast (Balanced / Flush Fit)

Profile: Wants a sportier stance without sacrificing daily usability.

Setup: 22x10.0J ET25

Cost: ~$3,000

Outcome: Noticeable visual upgrade, fuel economy drop within the expected range.

Case 3: Show Build (Max Aggressive)

Profile: Built primarily for shows or occasional track/show use.

Setup: 22x10.5J ET20

Cost: ~$5,500

Outcome: Maximum visual impact; daily comfort and fuel economy are heavily compromised, physical test fit required before production.

Decision Guide

What's your primary use? Daily commuting → Tier A/B. Weekend street driving → Tier B/C. Show or occasional track use → Tier D/E.

What's your budget? Under $800 → Tier A. $800-3,400 → Tier B/C. $3,400+ → Tier D/E.

How much does fuel economy matter? Very important → Tier A. Somewhat important → Tier B/C. Not a priority → Tier D/E.

Still unsure? Tier C (Balanced / Flush Fit) is the default choice for most Audi S8 [UK] owners.

Offset & Backspacing Reference

Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):

OE: 21x9.0J ET35 → ~6.38″ backspacing
Flush: 22x10.0J ET25 → ~6.48″ backspacing
Max: 22x10.5J ET20 → ~6.54″ backspacing

Want to check a different width or offset before you order? Use our Offset & Backspacing Calculator to solve the numbers yourself, or looking for your exact Audi spec, or want a wheel built to a custom offset for your Audi S8 [UK]? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.

Frequently Asked Questions

What bolt pattern (PCD) does the Audi S8 [UK] use?

The 2022 Audi S8 [UK] uses a 5x112 bolt pattern.

How many lug bolts does the Audi S8 [UK] use?

The Audi S8 [UK] uses a 5-lug bolt pattern (5x112), so you need a 5-lug forged wheel to bolt straight on.

What is the center bore size on the Audi S8 [UK]?

The Audi S8 [UK]'s center bore is 66.5mm. If an aftermarket wheel has a larger center bore than this, hub-centric rings are recommended so the wheel centers on the hub itself rather than relying on the lug bolts alone.

What size are the factory (stock) wheels on the Audi S8 [UK]?

Factory wheels on the Audi S8 [UK] are 21x9.0J F/R.

What is the biggest wheel size I can fit on my Audi S8 [UK] without rubbing?

The most aggressive fitment we recommend without fender work is 22x10.5J at ET20 offset. Going beyond this typically causes rubbing under compression unless you roll the fenders or add camber correction.

What does a flush wheel fitment look like on the Audi S8 [UK]?

For a flush look with minimal to no rubbing, we recommend 22x10.0J at ET25 offset as a starting point on a stock or mildly lowered Audi S8 [UK].

Do I need wheel spacers for my Audi S8 [UK]?

No. ANKUSI forges each wheel to your exact target offset, including the flush or max specs above, so you get the correct fitment without stacking spacers. Spacers are typically only used to push out an existing OE-offset wheel without replacing it, which isn't necessary when you're ordering a custom-offset forged wheel.

How do I calculate wheel backspacing for my Audi S8 [UK]?

Backspacing (in inches) = wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance). For example, the flush spec above works out to roughly 6.48" of backspacing.

What's the difference between wheel offset and backspacing?

Offset is the distance in millimeters from the wheel's true centerline to its mounting face (positive offset pulls the wheel in, negative pushes it out). Backspacing is the distance in inches from the mounting face to the back edge of the wheel barrel. They describe the same fitment from two different reference points, which is why ANKUSI lists both above — some shops and tuning guides quote offset, others quote backspacing.

Can I run staggered wheels (different sizes front and rear) on my Audi S8 [UK]?

The Audi S8 [UK] runs the same wheel size front and rear from the factory, so staggered fitment is not required. ANKUSI can still forge a staggered set (wider rear) on request if you want a more aggressive stance.
