2021 Audi TT RS Wheel Interchange

Tl;dr

2021 Audi TT RS OEM wheels are 19x9.0 ET52 with a 5x112 bolt pattern, 57.1 mm center bore, M14x1.5 threads, and tires 245/35R19. Use the on-page calculator to test alternative wheel widths, offsets, and tire sizes before buying.

Recommendation

Start by treating the OEM values as the baseline for fitment. Enter the OEM specs into the page calculator and compare any donor or aftermarket wheels there first. If you change rim width or offset, simulate tire sizes with the calculator to check clearance and overall diameter.

Use OEM values to source compatible wheels or to size adapters/spacers correctly.

Impact

Changing width or offset affects track width, steering feel, and suspension clearance. Larger overall diameter changes speedometer accuracy and gearing feel. Center bore mismatch can cause vibration unless using proper hub-centric rings. Incorrect lug threads or seat type can be dangerous.

Risks

• Rubbing on fenders, control arms, or strut boots when offset or width changes.
• TPMS sensor incompatibility or need for reprogramming with aftermarket wheels.
• Using incorrect lug nuts or bolts with different thread size or seat profile.
• Vibration from non hub-centric fitment without rings or proper centering.
• Brake caliper clearance issues with deep-dish or wider wheels.

Next actions

Checklist for a quick, safe workflow.

• Confirm trim-specific values. Some trims may vary. Check owner’s manual or dealer VIN lookup.
• Open the on-page calculator. Enter the OEM specs above and compare proposed wheels or tires.
• Simulate changed rim width, offset, and tire size to check clearance and diameter.
• Verify lug thread and seat type. Your TT RS uses M14 x 1.5 threads; confirm seat profile before buying hardware.
• Plan for hub-centric rings if center bore differs from 57.1 mm.
• Order compatible TPMS sensors or confirm reuse of OEM sensors.
• Have wheels installed and torqued to manufacturer spec using a calibrated torque wrench. Confirm torque value in the manual.
• After install, perform a road test and alignment check. Inspect for rubbing and re-torque lug nuts after 50 miles.

Gotchas: If a spec is not listed for your exact trim, confirm via the calculator or OEM documentation before purchase.

Tools: a good torque wrench is essential. Example search for options: torque wrench.

Next steps: run your desired wheel/tire combination in the on-page calculator now. Then follow the checklist to validate and install safely.
