Recorded OEM specifications for the 2017 Audi A7, donor years with overlapping ranges, and a calculator to compare a selected wheel. Range overlap is not a guaranteed fit.
Baseline mounting dimensions used for interchange decisions.
Multiple OEM configurations exist for this vehicle. Fitment can vary by trim, brakes, and factory wheel package – confirm your exact setup before buying.
Center-bore records disagree: year-level hub 66.6 mm vs trim range 66.5–66.5 mm. Interchange below does not treat this as an unqualified match.

These are vehicle-year records whose recorded OEM ranges overlap this 2017 Audi A7. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 188 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.
Center-bore records disagree (target year-level hub 66.6 mm vs trim range 66.5–66.5 mm; donor year-level hub 66.6 mm vs trim range 66.5–66.5 mm). Unqualified overlap is not claimed until the conflict is resolved.
Wheel width/offset data is incomplete.

Dataset suggestionHub-centric rings ≈ 66.6 → 66.5 mm – not a verified installation requirement.
Hub-centric rings of about 66.6 → 66.5 mm mm may be relevant if the wheel bore is larger than the hub; they cannot enlarge a smaller bore. Approximate position vs the mid OEM package: outer change -3 mm, inner change 3 mm. This uses aggregated width/offset ranges, not a specific wheel.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
Dataset suggestionWheel spacer ≈ 14.35 mm – not a verified installation requirement.
A spacer of about 14.35 mm is a dataset suggestion only; clearance is not verified. Estimated outer position is about 14.35 mm farther inward than the mid OEM package.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
Dataset suggestionWheel spacer ≈ 10 mm – not a verified installation requirement.
A spacer of about 10 mm is a dataset suggestion only; clearance is not verified. Estimated outer position is about 10 mm farther inward than the mid OEM package.
Only years with evidence-based interchange relationships are listed. Adjacent years are not assumed compatible.

Think of this page as a practical, safety-first fitment checklist for your 2017 Audi A7. I’ll start by clearing up a few common myths, then show you quick ways to verify a wheel or tire swap before you buy or bolt up.
These values reflect a common factory package on the 2017 A7. Some trims or option packages can differ. If your car’s sticker or manual shows something else, follow those values and use the calculator on this page to compare changes.
| Bolt pattern | 5x112 |
| Center bore | 66.6 mm |
| Thread size | M14 x 1.5 |
| OEM rim size | 19 x 8.5 in |
| Wheel offset | ET 32 mm |
| Backspacing | 5.51 in |
| OEM tire size | 255/40R19 |
Lots of Audi and VW models share the 5x112 pattern, so it feels interchangeable. Sellers often list “5x112 fits Audi” and that sounds convincing.
Bolt pattern is only one filter. You also need the right center bore, offset, brake clearance, load rating, and correct lug hardware style. For your A7, the hub is 66.6 mm. A wheel with a larger bore can work with hub-centric rings to 66.6 mm. A wheel with a smaller bore will not seat on the hub. Offset and width change clearance at the fender and the suspension. The thread size is M14 x 1.5 and the seat type depends on the wheel design, so match the seat type to the wheel manufacturer’s spec.
If the offset or width pushes the wheel too far out, the tire can rub fenders under load. If it sits too far in, it can rub the strut or control arm. A poor hub fit can cause vibration at highway speed. Wrong hardware seat type can loosen under load.
ET is measured in millimeters and it is not intuitive. Listings throw around ET numbers without context.
Here is a simple mental model. Positive ET moves the wheel inward toward the suspension. Lower ET moves it outward toward the fender. Your baseline is ET32 on an 8.5 inch rim. Changing width also shifts both inner and outer edges, so think offset and width together.
A small ET drop can fill the fender nicely if there is clearance. Too much drop can poke and rub. A large ET increase can hit the strut or liner. Backspacing of 5.51 inches is another way to visualize how far inward the wheel sits.
We talk about 19s or 20s a lot, so it feels like the whole tire grows with the rim size.
Tire diameter depends on section width and aspect ratio, not only rim diameter. Your OEM setup is 255/40R19. The 40 is the sidewall height percentage of 255 mm. If you move to a different rim diameter, an adjusted aspect ratio can keep overall tire diameter near stock.
Keeping overall diameter near stock helps speedometer accuracy, ABS, and ride quality. Large deviations can affect gearing feel and fender clearance.
This page’s calculator lets you compare Wheels from a donor vehicle versus Installed on your vehicle. You can also enter a Custom wheel size and a Custom tire size. When you change rim diameter, the tool updates tire diameter in the comparison so you see speedometer impact.
Factory wheel designs and tire sizes can vary by trim or appearance package. If your door placard or owner manual lists different sizes than the table above, treat those as your baseline. Use the calculator to compare from your actual OEM size and offset. If you are unsure about your exact offset, many OEM wheels have ET stamped on the back of the spoke.
The quick mental model is simple. Start from your known baseline of 19 x 8.5 ET32 with 255/40R19, 5x112, and a 66.6 mm hub. Use the calculator to see how a new width and offset change inner and outer clearances, then pick a tire that keeps overall diameter close. Confirm center bore fit, hardware type, and brake clearance, and you will land on a setup that feels factory-solid without surprises.
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.
