OEM wheel and tire fitment specs for the 2015 Audi A5, including bolt pattern (PCD), center bore diameter, thread size, rim diameter, rim width, wheel offset, and backspacing.
Recorded OEM specifications for the 2015 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 2015 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 2015 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.

2015 Audi A5 wheel fitment, bolt pattern, and swap guide
tl;dr
Core specs: 5x112 bolt pattern, 66.6 mm center bore, M14 x 1.5 threads.
Vehicle trims vary. Do not assume one size fits all.
Use the on-page calculator to compare donor wheels to your A5.
Match wheel diameter to tire diameter. Do not mix 20 inch wheels with 18 inch tires.
Start with your door-jamb tire size, then test changes step by step.
Confirm brake and fender clearance before driving. Torque to OEM spec.
Recommendation
I set up fitment in a simple lifecycle: baseline, compare, measure, then mount.
Baseline: Read your door-jamb tire size. Many 2015 A5 cars show 245/40R18. Some trims use larger wheel options. Specs can vary.
In the calculator: Set “Installed on” to 2015 Audi A5. Enter your actual wheel and tire as the baseline.
Comparisons: For donor wheels, enter their size and offset. If you have a 20 x 9 ET29 option, enter that exactly. The calculator will sync tire diameter when you change rim diameter.
Targets: Keep inner clearance safe, and keep outer poke within the fender. Watch scrub radius changes through offset moves.
Hardware: Keep 5x112, hub bore 66.6 mm or larger with proper rings, and M14 x 1.5 bolts of correct seat type and length.
Impact
Width change shifts both inner and outer positions. Wider wheels can contact liners or fenders.
Offset change alters inner clearance and poke. Lower ET moves the wheel outward, higher ET moves inward.
Larger diameter combos reduce sidewall and can sharpen steering. Ride can get firmer and more prone to impact damage.
Tire diameter changes affect speedometer and gearing feel. Keep overall diameter close to stock for best results.
Unsprung weight affects braking and ride. Lightweight, hub-centric wheels help.
Risks
Brake caliper clearance: Spoke shape and barrel drop matter. Check physically.
Hub fit: Audi hub is 66.6 mm. Larger wheel bores require 66.6 rings. Smaller bores will not fit.
Seat type: Match lug bolt seat to the wheel. OE Audi often uses ball seat, many aftermarket use cone. Do not mix.
Thread engagement: M14 x 1.5 bolts must engage fully without bottoming.
Speedometer error: Large tire diameter shifts can trigger ABS or stability complaints.
Fender contact: Compression, steering lock, and passengers can introduce rub that static checks miss.

How to use the calculator for a safe swap
Set “Installed on” to 2015 Audi A5.
Enter your current wheel and tire as the baseline.
Enter the donor wheel size and offset, or try a custom size.
Review inner clearance change. Negative numbers mean less room to the strut or liner.
Review outer poke change. Large positive numbers risk fender contact.
Check overall tire diameter change. Keep it close to stock to protect ABS and gearing feel.
Checklist
5x112 bolt pattern confirmed.
66.6 mm hub bore, or quality rings if wheel bore is larger.
M14 x 1.5 lug bolts, correct seat and length.
Spoke-to-caliper clearance checked with a straightedge and feeler gauge.
Fender and liner clearance checked at full lock and under load.
Torque all fasteners to OEM spec, then re-check after 50 to 100 miles.
Gotchas
Do not assume S-line, sport pack, and base have identical sizes.
TPMS strategy differs by market. Keep sensors compatible and properly coded if applicable.
Spacer use changes effective offset and bolt engagement. Account for both.
Aftermarket wheels may need shorter or longer bolts. Measure shank depth.
Next actions
Read your door-jamb tire size, then set the calculator baseline.
Model your target wheel and tire. Keep diameter and offset changes modest.
Measure brake and fender clearances before purchasing.
If any spec is unclear, confirm with the calculator on wheelinterchange.com and your Audi service information. That keeps the result safe and predictable.
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.
