OEM wheel and tire fitment specs for the 2017 Audi A5, including bolt pattern (PCD), center bore diameter, thread size, rim diameter, rim width, wheel offset, and backspacing.
Recorded OEM specifications for the 2017 Audi A5, donor years with overlapping ranges, and a calculator to compare a selected wheel. Range overlap is not a guaranteed fit.
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.

Donor vehicles with overlapping OEM specs
These are vehicle-year records whose recorded OEM ranges overlap this 2017 Audi A5. 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.
Wheel geometryOEM width/offset ranges overlap (not a specific wheel)
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. Approximate position vs the mid OEM package: outer change -0.67 mm, inner change -5.68 mm. This uses aggregated width/offset ranges, not a specific wheel.
Lug thread is not fully recorded for this comparison. Hardware must match the 2017 Audi A5 studs and the selected wheel’s seat. Unknown hardware is not a match.
Bolt pattern data is incomplete for a full interchange decision.

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 -5.68 mm, inner change -0.67 mm. This uses aggregated width/offset ranges, not a specific wheel.
Dataset suggestionWheel spacer ≈ 10.68 mm – not a verified installation requirement.
A spacer of about 10.68 mm is a dataset suggestion only; clearance is not verified. Estimated outer position is about 10.68 mm farther inward than the mid OEM package.

2017 Audi A5 Wheel Fitment Guide
Think of this as a practical, safety-first mental model for fitting wheels to your 2017 Audi A5. I’ll clear up common confusion, then show you how to confirm everything with the on-page calculator and OEM sources.
1. Misconception
Any wheel with a 5x112 bolt pattern will fit a 2017 Audi A5 just fine.
2. Why it seems true
Most listings highlight the bolt pattern and diameter. You see 5x112 and an 18 or 19 inch size, and it feels like a match. The rest looks like small print, so it gets skipped.
3. What is true
Fitment is a system. Bolt pattern is one part, but center bore, thread size, offset, width, backspacing, and tire diameter all affect safety and clearance. Trims and packages can vary, so it is normal to see mixed factory data for the same model year.
Here is what we have confirmed for the 2017 Audi A5. Some values may vary by trim or package. If yours differs, use the calculator on this page and verify with OEM sources.

Quick recap. The data above shows both a 20 inch wheel example and a 245/40R18 tire example. That is a signal that trims differ. Treat your car’s sticker and manual as the final word, then use the calculator to compare any change you are planning.
4. Implications
Here is the rule of thumb I use when test fitting wheels on the 2017 A5.
Bolt pattern and center bore are non negotiable. The wheel must be 5x112 and seat on a 66.6 mm hub. If the wheel bore is larger than 66.6 mm, use hub centric rings to 66.6 mm. If it is smaller, it will not fit the hub.
Lug hardware must match thread and seat style. Thread is M14x1.5. Seat style can vary by wheel brand. Confirm ball seat vs cone seat with the wheel maker. Match bolt length to wheel thickness and hub engagement.
Offset and width change inner clearance and outer poke. Too much poke can rub fenders. Too little inner clearance can rub struts or control arms. The calculator will show inner and outer changes from stock in mm.
Tire diameter affects speedometer and gearing feel. A change within about 2 percent of the original overall diameter is a practical target for daily use.
Brake caliper clearance is physical. Spoke shape and barrel design matter more than diameter alone. Do a visual and feel check with a straightedge before driving.
TPMS sensors need to be compatible. Reuse your sensors when possible, or confirm frequency and valve type with a sensor supplier.
Center caps are cosmetic. Audi caps may not fit aftermarket wheels without the correct bore and clip style.
If your car came on 18 inch tires like 245/40R18, and you want to move to a 19 or 20 inch wheel, use the calculator to keep overall diameter close. The tool will auto update tire diameter when you change rim diameter, so you can dial in a near stock rolling size.
5. Quick tests
Use the on page calculator
Set Installed on to 2017 Audi A5. This is your vehicle.
Enter your current wheel and tire if they differ from the known example. Use your door jamb tire label for the factory tire size.
Set Wheels from to your donor wheel, or use Custom wheel size and Custom tire size.
Adjust rim width and offset to match the wheel you are considering.
Watch the inner clearance and outer poke changes. Aim for small positive or negative changes that keep clearance safe.
Check the overall diameter change. Try to keep it within about 2 percent.
Physical check before mounting tires
Hub fit. Slide the bare wheel on the hub. It should sit snug on 66.6 mm with the correct ring if needed.
Lug engagement. Hand thread M14x1.5 bolts into the wheel. Confirm the seat style matches and that you get solid thread engagement.
Caliper clearance. Hold a straightedge across the hub face and measure to the caliper. Compare to the wheel’s backpad to spoke drop to confirm clearance.
Test fit with tires mounted
Turn to full lock left and right. Look and listen for liner or arm contact.
Bounce the suspension or drive slowly over a small ramp. Check fender and liner clearance under compression.
Road test at low speed. Re check bolt torque after a short drive. Use your owner’s manual for the torque value.
How to confirm any unknowns
Door jamb tire label. Confirms OEM tire size for your exact trim.
Owner’s manual. Confirms wheel hardware details and torque procedure.
OEM parts catalog or dealer by VIN. Confirms factory wheel size and any brake package that may affect clearance.
Use the calculator on this page to compare donor wheels against your 2017 A5, including custom sizes.
Start with the confirmed core specs for your A5. Use the calculator to visualize offset, width, and tire changes. Keep overall diameter close, protect inner clearance, and match hardware correctly. If a value on your car does not match the examples above, that is fine. Trim and package differences happen. Verify with your door label and manual, or by VIN with a dealer, and you will land on a clean, safe fit.
Methodology and sources
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
Bolt pattern / PCD
Center bore direction (donor wheel bore must not be smaller than the hub)
Wheel diameter, width, and offset against known OEM ranges
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.
