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.
ANKUSI Engineering Expert Advice
Wagons split the difference between sedan agility and load-carrying duty, and the wheels have to serve both roles. A forged wheel holds the same structural margin as the factory piece while trimming rotational weight, which benefits both the empty-car handling and the loaded-car ride.
The Audi A6 Avant runs a 5x112 bolt pattern, 66.5mm center bore, and a 19x8.5J, front and rear, wheel from the factory. Our Flush Fitment reference is 20x9.0J ET30, which tucks the tire under the fender lip on a stock-height Audi A6 Avant. Our Maximum Aggressive reference is 21x9.5J ET25 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Audi A6 Avant OE Wheel Specs
The 2026 Audi A6 Avant (Wagon) uses a 5x112 bolt pattern with a 66.5mm center bore. Factory wheels are 19x8.5J 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
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Audi A6 Avant (2026) we drill the 5x112 pattern and cut the centre bore to 66.5mm on our own CNC line, so the wheel hub-centres on the car with no spacer rings, in whatever diameter, width and offset you specify.
Converting these ET figures to backspacing? Use the wheel offset and backspacing calculator.

Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 19x8.5J ET40 → ~6.32″ backspacing
- Flush: 20x9.0J ET30 → ~6.18″ backspacing
- Max: 21x9.5J ET25 → ~6.23″ 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 A6 Avant? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Vehicles With the Same Hub as the Audi A6 Avant (5x112, 66.5 mm Bore)
In our database, 167 other vehicle entries from 6 makes use exactly the same 5x112 bolt pattern and 66.5 mm center bore. Factory wheels from these cars bolt on and center on the hub without rings; offset and width still have to be checked.
5x112 is used by 21.6% of the vehicle pages in our English fitment guide (1,407 of 6,503); 11.9% of those also use a 66.5 mm center bore.
Hub-Centric Rings for a 66.5 mm Center Bore
A wheel with a center bore larger than 66.5 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 66.6 mm | 66.6 → 66.5 mm |
| 67.1 mm | 67.1 → 66.5 mm |
| 70.1 mm | 70.1 → 66.5 mm |
| 70.5 mm | 70.5 → 66.5 mm |
| 73.1 mm | 73.1 → 66.5 mm |
ANKUSI forged wheels are bored to exactly 66.5 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Audi A6 Avant use?
The 2026 Audi A6 Avant uses a 5x112 bolt pattern.
How many lug bolts does the Audi A6 Avant use?
The Audi A6 Avant 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 A6 Avant?
The Audi A6 Avant'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 A6 Avant?
Factory wheels on the Audi A6 Avant are 19x8.5J F/R.
What is the biggest wheel size I can fit on my Audi A6 Avant without rubbing?
The most aggressive fitment we recommend without fender work is 21x9.5J at ET25 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 A6 Avant?
For a flush look with minimal to no rubbing, we recommend 20x9.0J at ET30 offset as a starting point on a stock or mildly lowered Audi A6 Avant.
Do I need wheel spacers for my Audi A6 Avant?
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 A6 Avant?
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 6.18" 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 A6 Avant?
The Audi A6 Avant 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.
Wheel Installation Reference: Torque, Thread & TPMS
Thread & Fastener: M14x1.5, ball-seat lug bolt (13mm radius).
Factory Torque Spec: 120 Nm (89 ft-lb). Shared VW/Audi Group ball-seat bolt spec used across most 5x112 Audi models.
TPMS: TPMS (Tire Pressure Monitoring System) has been federally mandated on all new light vehicles sold in the US since the 2008 model year. If your wheels use OE-style sensors, have them transferred or cloned to the new wheels at installation.
Tire Pressure: Always set tire pressure to the value on your vehicle's tire placard (driver's doorjamb or glovebox), not the max PSI printed on the tire sidewall — this is trim- and tire-size-specific and stays the same reference point when you switch to a different wheel and tire combination.
Reference data compiled from published OEM service specifications and cross-checked against independent repair sources; always confirm against your owner's manual or door-jamb placard before installation.
