OEM wheel and tire fitment specs for the 2013 Audi A5, including bolt pattern (PCD), center bore diameter, thread size, rim diameter, rim width, wheel offset, and backspacing.
Recorded OEM specifications for the 2013 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 2013 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 -1.67 mm, inner change -4.68 mm. This uses aggregated width/offset ranges, not a specific wheel.
Lug thread is not fully recorded for this comparison. Hardware must match the 2013 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; clearance is not verified. Donor width/offset sits outside the known OEM envelope for this vehicle.
Dataset suggestionWheel spacer ≈ 12.68 mm – not a verified installation requirement.
A spacer of about 12.68 mm is a dataset suggestion only; clearance is not verified. Estimated outer position is about 12.68 mm farther inward than the mid OEM package.

Goal
You need to confirm safe wheel and tire fitment for a 2013 Audi A5. This guide explains the checks and adjustments I recommend. Follow steps to avoid rubbing, improper fasteners, or unsafe clearances.
Prerequisites
Known OEM fitment for 2013 Audi A5 supplied here: bolt pattern 5x112, center bore 66.6 mm, thread M14 x 1.5, rim 17x7.5, offset ET28, backspacing 4.85 in, tire 225/50R17.
Access to the on-page wheel/tire calculator to compare donor wheels and adjust custom sizes. The calculator updates tire diameter when rim diameter changes.
Basic tools: torque wrench, jack and stands, caliper or ruler for clearance checks, test drive route.
Access to your vehicle's owner manual or dealer resources to validate torque and brake options. Some values vary by trim; do not assume they are identical across models.
Step by step
1. Verify OEM baseline
Record the provided OEM values into the calculator or your notes. Use this as the reference fitment. Do not replace these values with guesses.

2. Compare donor or custom wheel with the calculator
Enter the donor wheel sizes in the on-page calculator to compare track width, overall diameter, and clearance. Adjust custom rim diameter, width, offset, and tire sizes to see the numeric differences. Remember that changing rim diameter updates the tire diameter automatically.
3. Check center bore and fastening
Confirm center bore 66.6 mm matches the wheel. If the wheel bore is larger, plan to use hub-centric rings sized for 66.6 mm. If the bore is smaller, the wheel will not fit. The thread size M14 x 1.5 is the fastener thread specification. Confirm whether your car uses studs or lug bolts and the correct lug type before installation.
4. Measure physical clearances
Measure brake caliper clearance, suspension components, and inner fender clearance. Some Audi A5 trims have larger brakes than others. If brake size is unknown, measure clearance on the car or compare caliper dimensions to the wheel inner barrel before final selection.
5. Consider spacers and adapters carefully
Spacers change effective offset and track width. They can solve minor clearance issues but introduce trade-offs such as added load on studs and altered scrub radius. Use hub-centric spacers that match 66.6 mm bore if possible. Validate stud length and thread engagement when adding spacers.
6. Install, torque, and validate
Mount the wheel, torque fasteners to OEM specified values, and re-torque after 50 to 100 miles. If you do not have the OEM torque value, obtain it from the owner manual or dealer before proceeding. Perform a slow test drive and check for vibration or rubbing.
Validation
Use these validation checks before calling the job complete.
On-page calculator: confirm no more than a few percent change in overall tire diameter to avoid large speedometer error.
Physical check: spin the wheel and watch for rub at full lock and full suspension compression.
Fastener check: confirm thread engagement of at least the stud's threaded length or consult fastener supplier recommendations.
Centering: wheel should seat flush on the hub. If there is wobble, use appropriate hub-centric rings sized to 66.6 mm.
TPMS and valve clearance: ensure sensor clearance and recommended tire pressure settings are compatible.
Troubleshooting
Problem: Wheel does not clear brake caliper
Solution: Check wheel inner barrel and spoke clearance. Reduce wheel width or choose higher offset to move the wheel outward or inward as needed. Confirm caliper size variation by trim before changing wheels.
Problem: Wheel wobbles or is not centered
Solution: Use hub-centric rings sized for 66.6 mm. Verify hub face is clean and free of corrosion. Re-seat the wheel and tighten in a star pattern.
Problem: Fastener threads do not match
Solution: Confirm thread size M14 x 1.5 on your car. If the wheel requires different threads, replace fasteners with the correct type. Do not force mismatched bolts or studs.
Problem: Excessive steering feedback or vibration after spacers
Solution: Check spacer quality and wheel runout. Consider reducing spacer thickness or using a single-piece hub-centric spacer to minimize trade-offs. Re-balance the wheel and tire assembly.
Where to get parts
For hub rings, lug nuts, and centering hardware, search parts using targeted queries. Example tool query: hub centric rings 66.6 mm. Use the link below to browse compatible options.
You now have a clear checklist to confirm fitment for a 2013 Audi A5. Use the on-page calculator to quantify changes and validate clearances physically. When in doubt, confirm torque, brake options, and fastener types with OEM documentation or dealer support. These steps reduce risk and give you confidence to implement the final wheel choice safely.
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.
