2022 Audi A7 Wheel Interchange
OEM wheel/tire sizes and fitment specs for the 2022 Audi A7.
Baseline
You want a clean, safe fit on a 2022 Audi A7. Let’s start with what we know from OEM data we have on record. Some items may vary by trim or package. Treat these as a baseline and confirm against your door jamb label, owner’s manual, or the on-page calculator.
| Spec | Value | Notes |
|---|---|---|
| Bolt pattern | 5x112 | Must match exactly. |
| Center bore | 66.5 mm | Wheel bore must be 66.5 mm or larger. Rings if larger. |
| Thread size | M14 x 1.5 | Match seat type to wheel design. |
| Factory wheel | 18 x 8.0 | Recorded with ET 26 and 5.02 in backspacing. |
| Offset | ET 26 mm | Baseline reference for poke and inner clearance. |
| Backspacing | 5.02 in | Consistent with the 18x8 ET 26 record. |
| Tire size | 245/45R19 | Also recorded on some trims. This indicates multiple OEM packages. |
| Approx tire diameter | 703 mm (27.7 in) | Calculated from 245/45R19. Use as a rolling diameter reference, not a guarantee. |
The mix of 18-inch wheel data and a 19-inch tire size suggests multiple factory setups in 2022. That is normal. Confirm your exact build on wheelinterchange.com using the calculator, and by cross-checking OEM sources.
Edge cases
- Big brake packages may need more barrel clearance than typical. Even if bolt pattern matches, spoke design can foul the caliper.
- Air suspension or adaptive damping can shift ride height under load. Clearance at normal height may shrink in dynamic modes.
- Winter setups may run narrower tires. Chains can demand extra inner clearance that many wheels do not leave.
- Aftermarket wheel bores are often larger than 66.5 mm. Skipping hub-centric rings can cause shake at highway speed.
- Lug seat type can vary by wheel. Audi often uses ball seat on OEM bolts. Many aftermarket wheels use cone seat. A mismatch can loosen under load.
- Spacers can solve caliper rub, but only with proper extended M14x1.5 hardware. Short engagement is a risk.
- TPMS approach may differ by market or trim. Direct sensor vs indirect reset impacts wheel swap steps.
- Load rating matters. A7 is a heavy car. Under-rated wheels or tires can overheat and fail.
- Staggered widths change rotation patterns. That can mask inner shoulder wear until it is advanced.
Detection
Use the calculator on wheelinterchange.com
Set Installed on to 2022 Audi A7. Then set Wheels from to your donor vehicle. You can also use Custom wheel size and Custom tire size to model non-OEM setups. When you change rim diameter, the calculator updates tire diameter in the comparison. That helps you keep rolling diameter in a reasonable window.
- Inner clearance: Watch the change near the strut, spring perch, and upright. A small gain is usually fine. A loss can cause rub at load or full lock.
- Poke vs fender: Positive poke increase pushes the wheel outward. Big increases raise fender and liner contact risk on compression.
- Rolling diameter: Aim to stay close to the 703 mm reference if you are starting from 245/45R19. Many OEMs tolerate about 2–3% change, but confirm with OEM guidance.
- Caliper profile: Spoke-to-caliper clearance is not just offset. Spoke shape matters. If the calculator shows inner barrel close, plan a test fit.
Physical checks during test fit
- Hand-turn the hub with the wheel installed. Listen and feel for light contact.
- Check spoke-to-caliper gap through the window. At least a few millimeters is advisable under static conditions.
- Cycle steering lock-to-lock while compressing the suspension slightly. Look for liner marks.
- Road test gently. Any vibration suggests ring or balance issues, or a seat mismatch.
Mitigations
- Need inner clearance? A small decrease in offset may help. Re-check fender poke when you do.
- Need less poke? A slightly higher offset or a half-inch narrower wheel can help. Verify caliper clearance first.
- Keep the ride right: Use the calculator to pick a tire aspect ratio that maintains diameter near your baseline. That protects ABS, gearing feel, and speedometer behavior.
- Use hub-centric rings when the wheel bore is larger than 66.5 mm. Match ring ID 66.5 mm to the Audi hub, and ring OD to your wheel’s bore. Search: 66.5 hub centric rings
- Use the correct hardware. Match M14x1.5 thread and the wheel’s seat type. Search: M14x1.5 ball seat lug bolts
- Solving caliper rub with spacers? Use quality hub-centric spacers and proper extended bolts. Measure required thread engagement before purchase.
- Torque carefully and re-torque after 50–100 miles
