These are vehicle-year records whose recorded OEM ranges overlap this 2021 Audi S8. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 99 donor years. Listed 24 eligible overlaps (not all evaluated years are compatible). Showing all listed.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
Approximate position vs the mid OEM package: outer change -2.35 mm, inner change -10.35 mm. This uses aggregated width/offset ranges, not a specific wheel.

The following specifications are known for the 2021 Audi S8. Trim levels and factory wheel packages can differ. If a value on your car does not match, confirm it on your door jamb tire placard and in the owner’s manual, then use the on-page calculator to compare against any potential donor wheel or custom setup.
| Bolt pattern (studs x PCD) | 5x112 |
| Center bore | 66.5 mm |
| Thread size | M14 x 1.5 |
| Rim diameter | 19 in |
| Rim width | 8.0 in |
| Wheel offset (ET) | 32 mm |
| Backspacing | 5.26 in |
| Tire size example | 265/40R20 |
Note: The wheel and tire data above indicate that multiple OEM configurations may exist. If your S8 has a different factory wheel or tire size, treat the above as reference only and verify your exact specs before purchasing wheels or tires.
Plus sizing means increasing wheel diameter and using a lower profile tire to keep overall diameter similar. Many performance sedans are upgraded by +1 or +2 sizes. For your S8, use the calculator to model options and verify inner and outer clearances, brake clearance, and tire diameter.
Will 5x112 wheels from another Audi fit my 2021 S8?
Possibly. The bolt pattern matches, but you must also match or adapt the 66.5 mm center bore, verify offset and width with the calculator, ensure brake clearance, and confirm load rating. Do not rely on bolt pattern alone.
Do I need hub-centric rings?
If your new wheels have a center bore larger than 66.5 mm, use rings that reduce the wheel bore to 66.5 mm. If the wheel bore is smaller than 66.5 mm, the wheel will not seat on the hub.
What offset range will fit?
It depends on wheel width and spoke design. Use the calculator to compare against the OEM example of 19x8 ET 32 and check inner clearance to suspension and outer fender poke. Always test fit over the brakes.
What is the correct lug or bolt torque?
The exact torque for the 2021 S8 is not provided here. Use the value in your Audi owner’s manual or service documentation and torque with a calibrated wrench.
Can I use spacers on the S8?
Yes, if needed for clearance or stance. Use quality hub-centric spacers and the correct extended M14 x 1.5 bolts. Recalculate effective offset in the calculator and confirm fender coverage and brake clearance.
What tire size should I run on the OEM 19x8 wheel?
Tire selection depends on target diameter, load rating, and the tire manufacturer’s approved rim width range. Use the calculator to match overall diameter to your OEM package and confirm with tire maker fitment charts.
Will my TPMS work with new wheels?
Yes, if you transfer compatible sensors or install new sensors that match your vehicle’s system. A relearn or initialization may be required. Follow the owner’s manual or service procedure.
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
