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.

How To Use The Wheel Interchange Calculator

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:

  • Set Installed on to 2015 Audi A4 so the comparison is based on your car’s hub, brakes, and clearances.
  • Choose Wheels from to represent the donor vehicle or wheel you are considering. If exact trim is unknown, enter the custom wheel and tire details manually.
  • Use Custom wheel size to adjust rim diameter, width, and offset. The calculator will show how inner clearance and outer poke change versus your OEM 17x7.5 ET45.
  • Use Custom tire size to adjust section width and aspect ratio. When you change rim diameter, the tire diameter updates in the comparison so you can keep overall diameter near stock.
  • Review the results for inner clearance to suspension, outer poke at the fender, ride height change from tire diameter, and speedometer impact.
  • If any value is close or negative for inner clearance, recheck with a physical test fit before driving.

Fitment Checklist Before You Buy

  • Bolt pattern: Match 5x112 exactly.
  • Center bore: Audi hub is 66.6 mm. If the wheel bore is larger, use hub-centric rings to reduce to 66.6 mm. If the wheel bore is smaller, it will not fit.
  • Thread size: M14 x 1.5. Verify lug bolt length and seat type required by the wheel. Do not mix ball-seat and cone-seat hardware. Check your owner’s manual and wheel manufacturer’s guidance.
  • Offset and width: Start from OEM 17x7.5 ET45. Use the calculator to see inner clearance to struts and outer poke to fenders. Small offset decreases push the wheel outward, increasing fender risk. Small offset increases pull the wheel inward, increasing suspension and liner risk.
  • Brake clearance: Confirm spoke and barrel clearance over calipers and rotors. Some wheel designs in the same size may still foul the caliper.
  • Tire diameter: Keep overall tire diameter close to stock to protect speedometer accuracy and driveline. Many technicians target within about 3 percent of OEM. Use the calculator’s tire diameter comparison.
  • Load and speed ratings: Tires and wheels must meet or exceed your vehicle’s OEM load index and speed rating for safety.
  • TPMS: Plan for sensor swap or new programmable sensors compatible with your Audi. Follow relearn procedures after installation.
  • Test fit: Always test fit a front and a rear position, cycle steering lock to lock, and compress the suspension if possible to check clearance.

Plus Sizing And Common Upgrades

Plus sizing means increasing rim diameter while selecting a tire with a lower aspect ratio so overall tire diameter stays near stock. Example approach:

  • Start with OEM 245/45R17 on 17x7.5 ET45 as your baseline.
  • Choose a larger rim diameter in the calculator, then adjust tire aspect ratio to keep overall diameter within about 3 percent of OEM.
  • Increase wheel width in small steps and keep offset changes modest so inner and outer clearances remain safe. The calculator shows how each millimeter of offset change affects inner and outer position.

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.

Installation Tips

  • Prepare the hub: Clean rust and debris from the hub face. A thin film of anti-seize on the hub pilot can help prevent sticking, but keep it off the friction face of the rotor.
  • Hub-centric rings: If your wheel bore is larger than 66.6 mm, install proper rings so the wheel centers on the hub. Do not rely on bolts to center the wheel.
  • Dry, clean mating surfaces: Ensure wheel mounting pad and rotor hat are clean and dry. No paint or powder between them.
  • Hardware check: Verify M14 x 1.5 thread, correct seat type, and proper shank length if using aftermarket bolts. If using spacers, use longer, correct-grade hardware.
  • Torque by hand: Snug in a star pattern, then torque to the OEM spec from your owner’s manual using a calibrated torque wrench. Do not use an impact for final torque.
  • Re-torque: After 50 to 100 miles, recheck torque on all fasteners.
  • TPMS: Transfer or program sensors, install with new seals as applicable, and perform the relearn procedure per Audi instructions.

Tools And Helpful Supplies

FAQs

  • 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.

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
  • Lug thread / hardware differences (vehicle-side hardware)

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.
