Recorded OEM specifications for the 2015 Audi A4, 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 2015 Audi A4. 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). Unqualified overlap is not claimed until the conflict is resolved.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
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.
Donor width/offset sits outside the known OEM envelope for this vehicle. Precomputed data suggested a spacer; geometry was re-checked against OEM envelope.
Only years with evidence-based interchange relationships are listed. Adjacent years are not assumed compatible.

The following specifications are confirmed for at least one 2015 Audi A4 configuration. Other trims or brake packages may differ. If your trim varies, compare using the on-page calculator and verify against your owner’s manual and OEM parts resources.
| Bolt pattern | 5x112 |
| Center bore | 66.6 mm |
| Thread size | M14 x 1.5 |
| OEM rim diameter | 17 in |
| OEM rim width | 7.5 in |
| OEM wheel offset | ET 45 mm |
| Backspacing | 5.52 in |
| OEM tire size | 245/45R17 |
Notes: Offset, wheel width, and tire size can vary by trim or package. Always confirm the sticker inside your driver door jamb, your owner’s manual, and the wheel markings before purchasing.
The calculator lets you compare a donor vehicle’s wheels to your 2015 Audi A4, and also test custom wheel and tire sizes. Follow these steps:
Plus sizing means increasing rim diameter while selecting a tire with a lower aspect ratio so overall tire diameter stays near stock. Example approach:
Because trim and brake packages can differ, this guide does not list specific alternate sizes. Use the calculator to model your exact wheel width, offset, and tire size, then confirm with a physical test fit and OEM sources.
What is the bolt pattern on the 2015 Audi A4?
5x112.
What center bore does the 2015 Audi A4 use?
66.6 mm. If your wheel bore is larger, use hub-centric rings to adapt to 66.6 mm.
What is the thread size for the lug hardware?
M14 x 1.5. Verify seat type required by the wheel and match it exactly.
What is the OEM wheel and tire size listed here?
17x7.5 ET45 wheel with a 245/45R17 tire, and about 5.52 in of backspacing.
Will wheels from another vehicle fit my A4?
Only if the bolt pattern is 5x112, the center bore is 66.6 mm or larger with rings, offset and width clearances are safe, and brake and lug-seat compatibility are confirmed. Use the calculator to compare, then test fit.
How much can I change offset or width?
This varies by trim and brake package. Keep changes modest and use the calculator to monitor inner clearance and outer poke. Always test fit before driving.
What is the largest tire I can run?
It depends on wheel width, offset, suspension, and fender room. Use the calculator to keep overall diameter near stock and check for rubbing at full lock and over bumps.
What torque should I use on the lug bolts?
Use the OEM specification from your owner’s manual or service information for the 2015 Audi A4. Torque with a calibrated wrench and recheck after 50 to 100 miles.
Do I need hub-centric rings?
Use rings if your aftermarket wheel’s center bore is larger than 66.6 mm. If the wheel is exactly 66.6 mm, no rings are needed. If it is smaller, the wheel will not fit.
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.
