2005 Audi TT Wheel Fitment Guide

tl;dr

Start from the OEM baseline below. Keep 5x100 bolt pattern, 57.1 mm center bore, and M14 x 1.5 lug bolts. Use the on-page calculator to compare any donor wheels to your 2005 TT, and keep inner and outer clearances close to stock. Verify brake clearance and hub centering before driving.

Known OEM baseline

Notes: Wheel diameter and brake clearance may vary by trim or brake package. If your trim differs, confirm with the owner manual, your VIN at an Audi dealer, or by test fit.

Recommendation

I recommend a lifecycle approach. Start with the stock values above, then model changes in the WheelInterchange.com calculator.

• Set Installed on to 2005 Audi TT, then enter the OEM baseline.
• Enter the donor wheel and tire, or use Custom wheel size and Custom tire size.
• Match overall tire diameter close to stock to protect ABS and speedometer. The calculator updates tire diameter when you change rim diameter.
• Use offset to keep inner clearance and outer poke close to stock. Aim for minimal change on both sides of the tire.
• Keep the bolt pattern at 5x100. Keep center bore at 57.1 mm, or use proper hub-centric rings if the wheel bore is larger.
• Confirm bolt seat type matches the wheel, and use correct-length M14 x 1.5 lug bolts.

Impact

• Offset change affects fender poke, strut clearance, and steering feel.
• Wider rims can add grip but may rub fenders or liners.
• Larger diameter wheels may need lower-profile tires, which ride firmer.
• Incorrect center bore or seat type can cause vibration at speed.
• Wrong bolt length or pattern risks thread damage or loss of clamping force.

Risks

• Brake caliper clearance: Spokes and barrels must clear the caliper. Do a visual test fit.
• Inner suspension clearance: Check strut, spring perch, and control arms at full lock and compression.
• Fender and liner rubbing: Check outer clearance with steering turned and under load.
• Hub centering: 57.1 mm is required for hub-centric fit on the TT hub. Use quality rings if the wheel bore is larger. Do not rely on bolts to center.
• Lug interface: Audi OEM wheels typically use a specific seat type. Match ball or cone seat to the wheel. Mixing seat types is unsafe.
• Bolt engagement: Ensure full thread engagement to factory spec. Do not use overly short or long bolts.
• Adapters and wobble hardware: Avoid unless engineered for this platform and verified. They add complexity and risk.
• Load ratings: Wheel and tire load index must meet or exceed OEM requirements.

Next actions

Use this checklist before you buy or install.

• Confirm your trim and brake package. If uncertain, verify with the owner manual or your VIN at an Audi dealer.
• Open the on-page calculator. Set your 2005 TT as Installed on and input the OEM baseline.
• Input the donor wheel and tire, or a custom setup. Keep tire diameter close to stock. Watch inner and outer clearance deltas.
• Plan for hub centering. If the wheel bore is larger than 57.1 mm, source matching hub-centric rings.
• Match bolt seat type to the wheel. Order correct-length M14 x 1.5 bolts if needed.
• Test fit one corner. Spin the wheel, turn lock to lock, compress suspension if possible, and check caliper clearance.
• Torque all bolts to the factory spec using a calibrated wrench. Re-check torque after the first short drive.
• Road test. Listen and feel for vibration. If present, re-check centering, torque, and balance.

Helpful tools

• 1/2 inch drive torque wrench
• Thin wall lug socket set
• Wheel hanger guide pin M14 x 1.5
• 57.1 mm ID hub-centric rings

Gotchas

• Rim diameter may not clear larger brakes on some trims. Confirm physically.
• Aftermarket wheels often use a different bolt seat. Do not reuse OEM bolts blindly.
• Backspacing and offset both matter. Trust the calculator results, then verify on the car.
• Do not assume any 5x100 wheel will fit. Center bore, offset, and caliper shape still apply.

If a value is missing for your specific trim, use the calculator with your measured wheel, then confirm against OEM documentation. That avoids surprises and protects safety.
