OEM wheel and tire fitment specs for the 2012 Audi A4, including bolt pattern (PCD), center bore diameter, thread size, rim diameter, rim width, wheel offset, and backspacing.
Recorded OEM specifications for the 2012 Audi A4, 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 2012 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.
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). Unqualified overlap is not claimed until the conflict is resolved. Approximate position vs the mid OEM package: outer change -2.18 mm, inner change -4.18 mm. This uses aggregated width/offset ranges, not a specific wheel.
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. Precomputed data suggested a spacer; geometry was re-checked against OEM envelope.

2012 Audi A4 Wheel Fitment Guide | wheelinterchange.com
tl;dr
Use wheels that match 5x112, 66.6 center bore, and M14x1.5 hardware. Keep size and offset close to stock, then validate every change in the on-page calculator before you buy.
Recommendation
I recommend you start from the known OEM spec below, then make small, deliberate changes. Confirm bolt pattern, center bore, and hardware first. Use the calculator to compare any donor setup against your 2012 A4 and review inner and outer clearance plus tire diameter. Test fit one front corner before mounting tires when possible.

If your trim or package differs, some values can vary. Verify with your door jamb tire label, your owner’s manual, or OEM parts data by VIN. Then model your exact setup in the calculator.
Impact
Offset changes move the wheel in or out. This affects fender poke and strut clearance.
Width changes amplify that movement and can add inner barrel risk over large brakes.
Center bore must seat hub-centric. A larger wheel bore needs rings to 66.6 mm.
Tire size affects diameter and speedometer. The calculator updates tire diameter when you change rim diameter, so watch overall height.
Hardware type matters. The seat style of the bolt must match the wheel.
Risks
Vibration from wrong center bore or missing hub rings.
Fender rub or liner contact from excessive poke or diameter growth.
Strut, spring perch, or upright contact from reduced inner clearance.
Brake caliper interference with certain spoke profiles or small inner barrels.
Incorrect bolt seat type or length, especially when using spacers.
TPMS approach can vary by market and trim. Confirm whether sensors are required.
Speedometer error if overall tire diameter changes too much.
Next actions
Confirm your baseline. Check your door jamb label and verify 225/50R17 on 17x7.5 ET45 is what you have. If different, enter your actual values in the calculator as the installed vehicle.
Match the fundamentals. Any donor or aftermarket wheel must be 5x112. Center bore must be 66.6 mm or larger with hub-centric rings to 66.6 mm. Hardware must be M14x1.5 and the seat style must match the wheel.
Use the calculator. Compare your Audi against the donor setup. Adjust custom wheel width and offset until inner and outer clearances remain reasonable and tire diameter change is minimal.
Check brakes. Measure caliper-to-barrel clearance using a straightedge and ruler, or test fit the bare wheel on the front hub to confirm spoke and barrel clearance.
Plan hardware. If spacers are needed, select hub-centric spacers sized to 66.6 mm and use longer M14x1.5 bolts with the correct seat. Do not mix seat types.
Test fit one corner. Spin the wheel lock-to-lock, compress the suspension by hand, and recheck clearances before mounting tires.
Mount and torque. Use your service manual torque spec for M14x1.5 bolts. Re-torque after 50 to 100 miles.
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.
