OEM wheel and tire fitment specs for the 2011 Audi TT, including bolt pattern (PCD), center bore diameter, thread size, rim diameter, rim width, wheel offset, and backspacing.
2011 Audi TT Fitment Specs
Baseline mounting dimensions used for interchange decisions.
Multiple OEM configurations exist for this vehicle. Fitment can vary by trim, brakes, and factory wheel package – confirm your exact setup before buying.
Wheels That Interchange With a 2011 Audi TT
Results are evaluated from bolt pattern, center bore direction, OEM width/offset envelope, and lug hardware – not bolt pattern alone.
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.

tl;dr
Match bolt pattern and hub first. Then check offset, width, and tire diameter with the on-page calculator. Test-fit and verify brake and fender clearance before committing.

Some trims and brake packages may vary. Confirm against your door-jamb label and Audi documentation. If your trim differs, use the calculator to compare.
Recommendation
I approach fitment in this order to save time and rework.
Confirm hard constraints: 5x112 bolt pattern, 57.1 mm hub, M14 x 1.5 bolts.
Use the calculator on this page. Set Installed on to 2011 Audi TT with the OEM size above.
Enter the donor wheel or your Custom wheel size. Adjust rim width and offset.
Enter a matching Custom tire size. The tool updates overall diameter as you change rim diameter.
Review inner clearance to strut and outer poke to fender in the results.
Aim to keep overall tire diameter close to OEM for speedometer accuracy.
If a new wheel has a larger center bore, plan hub-centric rings to 57.1 mm.
Match lug bolt seat type to your wheel and hardware. Do not mix seat types.
Plan a physical test-fit on both front and rear before mounting tires.
Impact
Offset changes move the wheel inboard or outboard, affecting fender and strut clearance.
Wider rims can stretch or balloon tires and change sidewall support.
Overall diameter shifts speedometer, ABS logic, and gearing feel.
More poke can increase tramlining and fender liner contact at full lock.
Inner clearance affects brake calipers, knuckle, and spring perch.
Non-hubcentric mounting can introduce vibration at highway speeds.
Risks
Bolt pattern mismatch will not seat correctly and is unsafe.
Hub bore too small will not fit. Too large needs rings to center properly.
Wrong bolt seat type can loosen under load. Verify seat shape visually.
Offset too low or width too high can rub fenders or liners under compression.
Offset too high can contact struts or control arms on turn-in.
Brake caliper spoke clearance is wheel-design dependent. Measure or template-check.
Spacers change load paths and require appropriate hub-centricity and bolt length. Verify thread engagement.
TPMS hardware and frequency may vary by trim. Reuse or program accordingly.
