2000 Audi S4 Wheel Interchange

2000 Audi S4 Wheel Fitment Guide

You want wheels that fit your 2000 Audi S4 safely, without guesswork. The common confusion starts with mixed specs, offset changes, and tire diameter impacts. I will walk you through a careful, technician-grade process that keeps safety first and helps you validate every trade-off using the on-page calculator.

1. Goal

Choose and verify replacement wheels and tires for a 2000 Audi S4 that clear brakes and suspension, center properly on the hub, and maintain predictable handling and speedometer behavior.

2. Prerequisites

• Known OEM baseline for reference, listed below. Some values may vary by market or trim, so plan to validate.
• Access to the on-page calculator on wheelinterchange.com.
• Basic tools and supplies:
  • Torque wrench and 17 mm socket or as required for your bolts
  • Straightedge and tape measure for quick clearance checks
  • Hub-centric rings if using wheels with a larger center bore than 57.1 mm
  • Quality wheel bolts in the correct thread size if length or seat type changes

Known OEM baseline for 2000 Audi S4

Note the rim diameter and tire size appear inconsistent. That suggests either mixed data or multiple OEM configurations. Assumption-free approach is recommended. Use the on-page calculator and your vehicle’s tire placard to confirm your specific baseline.

3. Step by step

Step 1. Confirm your exact OEM baseline

• Check the tire placard in the driver door jamb for the factory tire size and load rating.
• Inspect your current wheels for size, width, and offset markings, usually cast inside the spokes or barrel.
• Enter 2000 Audi S4 as “Installed on” in the calculator, then select the closest OEM setup to what you see on your car. This creates a reliable starting point.

Step 2. Set up the calculator comparison

• Option A, donor vehicle: If you have wheels from another car, enter that vehicle under “Wheels from.”
• Option B, custom wheel: Use “Custom wheel size” to enter rim diameter, width, and offset. The calculator will show inner clearance and outer position changes against your baseline.
• Custom tire: Adjust section width and aspect ratio to manage overall tire diameter. When you change rim diameter, the tool updates tire diameter in the comparison so you can track speedometer impact.

Step 3. Respect core constraints

• Bolt pattern must match 5x112. Adapters add complexity and risk. Direct fit is recommended.
• Center bore must fit 57.1 mm. If the new wheel bore is larger, use hub-centric rings sized 57.1 to the wheel bore. Smaller bores will not fit.
• Thread size is M14 x 1.5. If you change hardware length or seat style, ensure full thread engagement and correct seat geometry for the wheel.
• Offset trade-off: Moving to a lower ET pushes the wheel outward, higher ET pulls it inward. Use the calculator to monitor inner strut clearance and outer fender poke.
• Spacers: If used, effective offset decreases by the spacer thickness. Confirm longer bolts are used where required, and maintain hub-centricity.

Step 4. Manage tire diameter and width

• Target an overall diameter close to your confirmed OEM tire diameter. Smaller changes simplify ABS and speedometer behavior.
• Wider tires increase grip but can reduce inner clearance at full lock and add fender risk on compression. Use the calculator’s inner and outer movement readouts to plan a safe margin.

Step 5. Plan a physical test fit

• Clean the hub face. Mount one front and one rear wheel without center caps. Hand rotate to check brake caliper clearance.
• Set the vehicle on the ground, turn steering lock to lock, and drive slowly over a bump. Listen and look for contact.

4. Validation

• Hub fit: Wheel centers snugly on the 57.1 mm hub using proper rings if needed. No play.
• Lug hardware: M14 x 1.5 threads start smoothly by hand. Seat type matches wheel design. Torque to the OEM spec in a star pattern. Re-torque after 50 to 100 miles.
• Clearance: No contact with calipers, struts, control arms, or liners through full steering range and suspension travel.
• Ride and balance: No vibration at highway speed. If vibration appears, check hub-centricity and wheel balance first.
• Speedometer: Road test against GPS. If the speed reading changed more than expected, revisit tire sizing in the calculator.

5. Troubleshooting

• Vibration after install: Usually hub-centricity. Confirm ring size 57.1 mm at the hub and correct outer size for the wheel bore. Re-seat the wheel, then road-force balance if needed.
• Rubbing on inner fender or liners: Offset likely too high or tire too wide. In the calculator, reduce width or move to a lower ET. Small spacer changes can help, but validate bolt length and hub engagement.
• Outer fender poke or contact on bumps: Offset too low or tire diameter too large. Nudge ET upward or reduce section width or aspect ratio.
• Brake caliper interference: Barrel profile or spoke design is the constraint. Check with a template if available, or test a wheel with more caliper-friendly spoke clearance.
• Lug bolts bottoming or not engaging enough threads: Verify shank length and thread engagement. Replace with the correct M14 x 1.5 length that matches your wheel and spacer stack.

6. Wrap up

Your 2000 Audi S4 uses a 5x112 pattern, 57.1 mm hub, and M14 x 1.5 hardware. Offset and tire diameter choices drive the main trade-offs. Start by confirming your OEM baseline, then use the calculator to quantify inner and outer movement along with tire diameter changes. Validate hub fit, torque, and clearances before daily use. When in doubt, keep changes modest and test fit under real load. That approach moves you from confusion to clarity, with safe, predictable results.
