2011 Audi A3 Wheel Interchange

2011 Audi A3 wheel fitment guide

tl;dr

• Known OEM fitment for 2011 Audi A3: 5x112, 57.1 mm bore, M14 x 1.5 bolts, 16x6 ET50 wheel, 205/55R16 tire, backspacing 4.97 in.
• Stick close to OEM unless you verify clearance with the calculator.
• If changing sizes, keep overall tire diameter change small, about 3 percent.
• Confirm bolt-seat type and torque in your owner manual or OEM service data.

Recommendation

I recommend you start from the OEM baseline, then model any change with the on-page calculator before buying. This avoids brake, fender, and hub issues.

• Wheels from: set the donor wheel and tire you are considering.
• Installed on: select 2011 Audi A3.
• Use Custom wheel size and Custom tire size to test width, offset, and diameter changes. The tool updates overall tire diameter as you change rim diameter.
• Aim to keep overall tire diameter within about 3 percent of OEM for speedometer and ABS behavior.
• Check inner clearance to strut and spring, and outer poke relative to the fender.
• Keep the center bore at 57.1 mm. Larger is acceptable with hub-centric rings. Smaller will not fit.
• Threads must remain M14 x 1.5. Audi uses wheel bolts, not studs.

Unknowns like torque spec or bolt-seat style can vary by trim or market. Confirm in your owner manual or OEM service portal, or match to the markings on your current OEM wheel and bolts.

Impact

• Offset change: lower ET pushes the wheel outward, higher ET pulls it inward. This changes inner clearance and fender poke.
• Width change: half the added width goes inside, half outside, adjusted by offset. Verify both sides with the calculator.
• Diameter change: larger overall diameter raises the car slightly and lowers indicated speed. Smaller does the opposite.
• Hub bore and rings: using rings centers the wheel on the hub to reduce vibration.
• Fastener seat type: correct seat contact prevents loosening and damage.

Risks and gotchas

• Hub-centric fit: a wheel with a bore smaller than 57.1 mm will not seat. Larger bores need 57.1 mm rings to stay vibration free. Try: hub centric rings 57.1
• Bolt-seat mismatch: many OEM Audi wheels use ball-seat bolts, some aftermarket use cone-seat. Match the bolt seat to the wheel. Try: M14x1.5 ball seat wheel bolts
• Brake caliper clearance: spoke shape matters, not only offset. Always test fit and rotate the wheel by hand.
• Spacer use: requires hub-centric spacers and longer M14 x 1.5 bolts with correct seat. Verify shank engagement.
• TPMS: the car may use indirect or direct systems depending on market. Relearn may be needed after changes.
• Torque: torque value can vary by wheel and trim. Use your owner manual spec and a calibrated wrench. Try: torque wrench 1/2 inch drive
• Mounting: Audi uses wheel bolts. A guide pin helps align the wheel safely. Try: wheel hanger guide pin M14x1.5

Next actions

• Confirm your door-jamb tire label and owner manual against the OEM specs above.
• Open the calculator on wheelinterchange.com. Set 2011 Audi A3 in Installed on.
• Enter any candidate wheel in Wheels from. Adjust width, offset, and tire to model fit.
• Check inner clearance and outer poke in the tool. Keep overall diameter change small, about 3 percent or less.
• Ensure center bore 57.1 mm or use correct hub-centric rings.
• Match bolt-seat type, thread M14 x 1.5, and confirm torque from OEM sources.
• Test fit one corner. Spin by hand to confirm caliper clearance. Verify that the hub face sits flush.
• Torque in a star pattern on clean, dry threads. Re-torque after 50 to 100 km.

If a spec you need is not listed here, do not guess. Use the on-page calculator to model geometry, then verify torque, bolt-seat, and TPMS details with the owner manual or an OEM service source before purchase.
