2000 Audi TT Wheel Interchange

tl;dr

Your 2000 Audi TT uses 5x100 bolt pattern, 57.1 mm center bore, and M14 x 1.5 wheel bolts. Stock wheel is 16x7 ET31 with 205/55R16 tires. Match bolt pattern and center bore first, then keep width and offset close to stock. Use the on-page calculator to validate inner clearance, outer poke, and tire diameter. Use hub-centric rings if the donor wheel’s bore is larger than 57.1 mm. Confirm bolt seat type and torque with OEM sources before driving.

Recommendation

1) Establish your baseline

These values are your reference for safe interchange checks.

2) Screen any donor wheel

• Bolt pattern must be 5x100. No adapters recommended unless professionally engineered.
• Center bore must be 57.1 mm or larger only. Never smaller. Use hub-centric rings to 57.1 if larger.
• Thread size must match M14 x 1.5. Verify bolt or nut seat style with the wheel maker.

3) Validate size with the calculator

In the calculator, set “Installed on” to your 2000 TT using the above baseline. Enter the donor wheel specs under “Wheels from” or use “Custom wheel size”. Adjust width and offset until:

• Inner clearance does not decrease to the point of contact with strut or liner.
• Outer poke stays inside the fender or within your local inspection limits.
• Tire diameter change is minimal to preserve speedometer and ABS behavior.

4) Hardware and install

• Use hub-centric rings to 57.1 mm when the wheel bore is larger.
• Use proper-seat M14 x 1.5 bolts or nuts to match the wheel seat.
• Torque to the factory spec found in your owner’s manual or service data.

5) Test-fit lifecycle

• Hand rotate front and rear with wheels installed. Listen for rubs.
• Cycle steering lock to lock. Check strut, spring perch, and liner clearance.
• Road test slowly. Re-torque after a short shakedown and again after 50–100 miles.

Impact

• Offset shifts change inner clearance and outer poke. Small changes are easier to manage.
• Wider rims may need higher offset to protect inner clearance.
• Larger tire diameter affects speedometer and gearing feel.
• Non hub-centric mounting can cause vibration at highway speeds.
• Spacers alter hardware engagement and bearing load. Use only when properly engineered.

Risks

• Rubbing on strut, spring perch, or fender lip under compression.
• Incorrect seat style bolts causing loosening or damage.
• Insufficient thread engagement on bolts or studs.
• Brake caliper spoke interference on some wheel designs.
• Speedometer error if tire diameter change is excessive.
• Vibration if the wheel is not hub-centric to 57.1 mm.

Next actions

Checklist

• Confirm 5x100 and 57.1 mm on any candidate wheel.
• Verify M14 x 1.5 hardware and correct seat style for the wheel.
• Use the calculator to compare inner clearance, poke, and tire diameter.
• Plan hub-centric rings if the donor bore is larger than 57.1 mm.
• Test-fit, torque to spec, and re-torque after initial miles.

Gotchas

• Do not force a smaller center bore onto the hub.
• Do not mix seat styles between bolts and wheel seats.
• Avoid large offset swings without measuring clearances on the car.
• Spacers require longer hardware and careful centering. Verify with the calculator and a physical test.

Tools and parts

• 57.1 mm hub-centric rings
• M14 x 1.5 wheel bolts, ball seat (verify seat style for your wheel)
• 1/2 inch drive torque wrench
• 6 inch digital caliper for measuring bores and hardware length

How to use the calculator efficiently

Set “Installed on” to 2000 Audi TT with the stock values above. Enter the donor wheel under “Wheels from” or type a custom size. Adjust rim width and offset until inner clearance is acceptable and poke remains controlled. Then add a “Custom tire size” if your rim diameter changes. The tool will update overall diameter so you can keep speedometer error in check. Save the combination that clears the car, then confirm with a physical test-fit.

If any spec for a candidate wheel is unknown, pause and confirm with the seller, the wheel manufacturer, or Audi OEM service data. The calculator helps visualize changes but it cannot replace a hands-on clearance check.
