2023 Audi RS 5 Wheel Interchange

OEM wheel/tire sizes and fitment specs for the 2023 Audi RS 5.

Introduction

Misconception: swapping wheels on a 2023 Audi RS 5 is just a matter of matching diameter. I used to think that too. It’s easy to focus on rim size and overlook studs, center bore, threads, and offset.

Why it matters: wrong fitment can lead to vibration, loose lug nuts, rubbing, or worse. Think of it as a systems check. Use the on-page calculator and factory sources to fill gaps you don’t know yet.

Quick fitment summary (TL;DR)

  • Bolt pattern: 5x112. That part is known and important.
  • Center bore: 66.5 mm. Wheel must be hub-centric or use a correct ring.
  • Thread size: M14 x 1.5. Use matching lug nuts or adapters sized for this thread.
  • Rim diameter, rim width, offset, backspacing, and OEM tire sizes are unknown here. Confirm with the calculator or OEM.
  • Offset and backspacing affect clearance for calipers and fenders. Don’t guess them.
  • If you swap wheels from another Audi, double-check offset and width even when bolt pattern matches.
  • Measure center bore and test-hold new wheels before final torque. A hub-centric fit reduces stress.
  • When in doubt, use the on-page wheel/tire calculator to preview clearance and speedo change.

How to use the calculator

  • Step 1: Set the “Installed on (your vehicle)” to 2023 Audi RS 5. That loads known specs we have. Unknown values will be flagged.
  • Step 2: Choose a donor wheel or enter “Custom wheel size” (rim diameter, width, offset). If you don’t know a value, leave it to test ranges.
  • Step 3: Enter “Custom tire size” or pick a common tire. When you change rim diameter, the calculator auto-updates overall tire diameter.
  • Step 4: Check clearance warnings the calculator shows for calipers, fenders, and inner well. Pay attention to offset and backspacing results.
  • Step 5: Use the comparison output to see change in rolling diameter and effective gearing. That helps avoid speedometer errors.
  • Step 6: If bolt pattern or center bore differ, the calculator will flag fitment as incompatible. Do not proceed without confirming adaptors or rings.
  • Step 7: When values are unknown, use the calculator to simulate common sizes, then verify physically at the wheel or with OEM specs.

What each specification means (concise)

  • Bolt pattern (studs x PCD) - layout of lug holes and circle diameter. 5x112 means five studs on a 112 mm circle.
  • Center bore (mm) - hole diameter in the wheel that centers on the hub. Hub-centric fit matters for vibration control.
  • Thread size - thread pitch and diameter of wheel studs or lug bolts. M14 x 1.5 is the thread spec here.
  • Rim diameter (in) - the wheel diameter that the tire bead seats on. Affects speedo and tire options.
  • Rim width (in) - inside width where the tire seats. It affects acceptable tire section widths.
  • Wheel offset (ET, mm) - distance from wheel centerline to mounting face. Positive ET moves wheel inward.
  • Backspacing (in) - distance from mounting face to inner lip of the wheel, useful for measuring clearance.
  • Tire section width / aspect ratio / rim diameter - define tire size and overall diameter. Changes alter speedometer and clearance.

Mismatch troubleshooting

Bolt pattern

Misconception: any 5-lug wheel from Audi will fit. Why it seems true: many Audis share five studs. What is true: the pitch circle diameter must match 112 mm. Implications: wrong PCD means the wheel won’t sit on the hub or the bolts won’t line up. Quick tests: remove a wheel and measure the PCD or use a PCD gauge, or check the wheel stamping and OEM sheet.

Center bore

Misconception: a slightly larger center bore is okay. Why it seems true: the lug nuts can pull the wheel tight. What is true: an oversized bore without a proper hub-centric ring can produce vibration and stress on studs. Implications: use hub-centric rings to match 66.5 mm to the wheel bore, or confirm the wheel is hub-centric to 66.5. Quick tests: dry-fit the wheel, spin and feel for wobble; measure bore with calipers.

Thread size

Misconception: lug nuts are interchangeable. Why it seems true: many nuts look similar. What is true: this RS 5 uses M14 x 1.5 threads. Implications: wrong threads can strip studs or cross-thread, a safety hazard. Quick tests: check the owner’s manual, remove a lug to inspect threads, or measure with a thread gauge.

Offset

Misconception: a small offset change is harmless. Why it seems true: a few millimeters feels insignificant. What is true: even moderate offset shifts change scrub radius and caliper clearance. Implications: excessive negative offset can cause rubbing or stress suspension components. Quick tests: use the calculator to preview offset effects, measure backspacing, and test-fit before final torque.

OEM wheel & tire specs for 2023 Audi RS 5

SpecificationValue
Bolt pattern5x112
Center bore (mm)66.5
Thread sizeM14 x 1.5
Rim diameter (in)Unknown - confirm with OEM, door placard, or the calculator
Rim width (in)Unknown - confirm with OEM or factory wheel stamping
Wheel offset (ET, mm)Unknown - varies by wheel option and trim; check factory spec
Backspacing (in)Unknown - calculate from width and offset or measure physically
Tire section width (mm)Unknown - depends on factory tire choice
Tire aspect ratio (%)Unknown - depends on factory or optional tires
Tire rim diameter (R)Unknown - confirm with sticker or dealer

Quick recap: we list the confirmed bolt pattern, center bore, and thread size. Other specs vary by trim or option and should be verified.

Common mistakes

  • Relying only on bolt pattern and ignoring center bore and offset. That often causes vibration or rubbing.
  • Using the wrong lug nuts with M14 x 1.5 studs. That can damage threads.
  • Assuming OEM rim width and offset match aftermarket wheels. This creates clearance issues.
  • Not test-fitting before driving. Even if a wheel "looks" correct, small misfits show up at speed.

Roadside & emergency advice

If you have a flat, use the factory spare or the Audi tire repair kit when available. Think of it as a temporary measure to get to a safe repair location. If you must swap wheels roadside, use the matching lug nuts and torque to spec, and drive slowly to a shop for verification.

If a wheel vibrates after replacement, stop and recheck the wheel mounting, lug torque, and hub-centric fit before further driving. Vibration can mean the wheel didn’t center properly or a nut is loose.

FAQ

Can I use wheels from another Audi model?

Why it seems true: same brand sometimes shares patterns. What is true: matching 5x112 helps, but check center bore and offset. Use the calculator to compare actual fitment.

Are hub-centric rings necessary?

Why it seems true: many wheels seem to sit fine without rings. What is true: rings that match 66.5 mm center bore to the wheel reduce vibration. Quick test: dry-fit and feel for wobble at low speed.

How do I confirm unknown OEM values?

Use the door jamb placard, owner’s manual, factory wheel stamping, or contact a dealer. The on-page calculator can help you explore plausible sizes until you confirm exact specs.

Where to get correct lug nuts or rings?

Search parts by thread size and bore dimension. For example, hub centric rings sized to 66.5 mm are common. If you want a quick parts search, try this tool search: hub centric rings 66.5 on Amazon.

Safety disclaimer

I’m a peer sharing practical fitment guidance, not a substitute for official specs. We must not invent or assume unknown factory values. If a spec is listed above as unknown, confirm it with the door placard, owner’s manual, OEM dealer, or the on-page calculator before purchasing or installing wheels. Incorrect fitment can cause loss of control, damage, or injury. When in doubt, consult a qualified technician.
