2000 Audi A4 Wheel Interchange

Known OEM Fitment For 2000 Audi A4

Important: Values can vary by trim, market, and option package. Only confirmed items are listed below. If a value is not shown for your exact configuration, use the on-page calculator and verify against your owner’s manual, the spare tire well label, or an Audi parts catalog before purchasing.

The wheel and tire examples above may come from different OEM packages. Your 2000 A4 may have left the factory with a different rim and tire size. Always measure your current setup or decode the VIN with an Audi dealer to confirm.

How To Use The Wheel Interchange Calculator

• Open the calculator and set Installed on (your vehicle) to 2000 Audi A4.
• Pick Wheels from (donor vehicle) to compare a potential replacement wheel or a known OEM package.
• Use Custom wheel size to enter rim diameter, width, and offset you want to try. As you change rim diameter, the tool will update overall tire diameter in the comparison.
• Use Custom tire size to set section width and aspect ratio. Aim to keep overall diameter close to your verified OEM diameter to protect gearing and speedometer accuracy.
• Review inner clearance to strut and brake, outer poke to fender, and scrub radius change. The calculator shows how offset and width changes move the wheel inboard and outboard.
• When results look good, test fit a single wheel before mounting tires whenever possible to confirm caliper clearance, hub fit, and lug engagement.

Fitment Checklist Before You Buy

• Bolt pattern: Must be 5x112.
• Center bore: 57.1 mm hub. If the wheel bore is larger, plan hub-centric rings. If smaller, the wheel will not fit.
• Offset: Start from the known OEM ET45 example. Small changes affect inner strut clearance and outer fender poke. Verify with the calculator and a physical test fit.
• Wheel width and diameter: Confirm against your brake package and fender clearance. Larger diameters often require lower-profile tires to maintain overall diameter.
• Tire overall diameter: Keep close to your verified OEM diameter to maintain speedometer accuracy and prevent rubbing. Use the calculator to see the percentage change.
• Brake and caliper clearance: Visually check spoke and barrel clearance on a test fit. Spin the wheel by hand to ensure no contact.
• Lug hardware: Thread size M14x1.5. Match seat type to the wheel and ensure proper bolt length and engagement.
• Load rating: Wheel and tire load indexes must meet or exceed the vehicle’s GAWR. Check door jamb and tire sidewall.
• Hub condition: Clean rust and debris so the wheel seats fully. Verify the wheel sits flush on the hub face.
• Legal and seasonal needs: Check local regulations and consider snow chain clearance if applicable.

Plus Sizing And Common Upgrades

Many owners move between 15, 16, and 17 inch wheel packages on the 2000 A4 platform. The ideal setup for your car depends on brakes, suspension height, and fender clearance. Because factory configurations varied by trim, follow these guidelines rather than assuming a specific size will fit:

• Maintain overall tire diameter: Use the calculator to keep the new tire’s outer diameter close to your verified OEM diameter. Small differences can impact ABS calibration and speedometer readings.
• Offset control: Keep offset close to the OEM example ET45 unless you have measured room to change it. Lower ET pushes the wheel outward, higher ET pulls inward.
• Width changes: Wider wheels increase inner and outer movement. Check both sides for clearance to struts, liners, and fender lips.
• Ride and handling trade-offs: Larger diameter wheels with lower-profile tires sharpen steering but can reduce ride comfort and increase impact risk on rough roads.
• Brake clearance: If you have upgraded brakes, confirm barrel and spoke clearance on the new wheel design.

Installation Tips

• Test fit first: Mount one wheel without a tire if possible to confirm center bore fit, caliper clearance, and lug engagement depth.
• Clean mating surfaces: Remove rust and debris from the hub face and center spigot. A light smear of high-temp anti-seize on the hub center only can help prevent sticking. Do not lubricate lug bolt threads unless specified by Audi.
• Use a guide pin: An M14x1.5 wheel hanger helps align heavy wheels on VAG hubs without damaging threads or rotors.
• Tighten in a star pattern: Hand start bolts, snug in a criss-cross pattern, lower the car, then torque to the factory spec from your owner’s manual.
• Re-torque: After 50 to 100 miles, re-check torque to the factory specification.
• Tire pressure: Set to the door-jamb label values when cold. Re-check after temperature swings.

Tools And Helpful Supplies

• Wheel hanger guide pin M14x1.5
• 1/2 inch drive torque wrench
• Hub-centric rings 57.1 mm (assortment)
• Tire pressure gauge

FAQs

• What does 5x112 mean on my Audi A4?

  It indicates 5 wheel bolts arranged on a 112 mm diameter circle. Replacement wheels must match 5x112 to mount correctly.

• Do I need hub-centric rings?

  The A4 hub is 57.1 mm. If your aftermarket wheel has a larger center bore, use 57.1 mm hub-centric rings so the wheel centers on the hub. If the wheel bore is smaller than 57.1 mm, the wheel will not fit.

• What offset should I use?

  An OEM example is ET45. Stay close to this unless you have confirmed inner and outer clearances with the calculator and a test fit. Lower ET pushes the wheel outward; higher ET pulls it inward.

• Will 18 inch wheels fit my 2000 A4?

  Fitment depends on your brakes, suspension, tire size, and offset. Use the calculator to keep overall tire diameter near OEM and verify inner and outer clearances. Test fit before buying tires.

• What lug bolts does it use?

  Thread size is M14x1.5. Match the seat type to your wheel design and ensure proper bolt length and thread engagement. Do not mix ball and cone seats.

• What is the correct torque spec?

  Consult your owner’s manual or an Audi service manual for the exact torque specification for your trim and wheel material. Re-torque after 50 to 100 miles.

• How close should my new tire diameter be to stock?

  Use the calculator to compare. Keep diameter as close as possible to your verified OEM size to protect speedometer accuracy, ABS behavior, and gearing. Small percentage changes are usually acceptable, but confirm physically for clearance.
