OEM wheel/tire sizes and fitment specs for the 2015 Audi RS 5.

2015 Audi RS 5 wheel fitment guide

tl;dr

Match 5x112, 66.5 mm hub, and M14x1.5 bolts. Keep offset near ET 26 and tire diameter close to stock. Use the on-page calculator to verify inner and outer clearance before you buy.

Recommendation

I recommend starting from the known data below, then confirming your exact factory size from your door placard or VIN lookup. The provided inputs show both a 20 inch rim entry and a 19 inch tire entry. That suggests multiple factory packages or a mixed record. Do not assume. Set your current size in the calculator, then compare any donor or custom setup to it.

  • Stud pattern: 5x112
  • Center bore: 66.5 mm
  • Threads: M14 x 1.5 (use matching bolt seat for the wheel)
  • Reference wheel: 9.0 in width, ET 26 mm, backspacing 5.52 in
  • Reference tire entry: 265/35R19

Stay close to ET 26 and 9.0 in width unless you verify clearances. Keep overall tire diameter change minimal to preserve speedometer and ABS behavior.

Impact

  • Offset change affects fender poke and inner clearance to struts and liners.
  • Width change alters both inner room and outer poke. Wider needs careful offset.
  • Diameter plus tire size affects gearing, speedometer, and brake clearance.
  • Center bore fit controls hub centering. 66.5 mm hub is required on the car.
  • Bolt length and seat type affect clamping safety.

Risks

  • Inner rub on suspension or brake calipers if offset is too high or spokes are tight.
  • Outer fender contact on compression if offset is too low or tires are tall or wide.
  • Vibration if wheels are not hub centric to 66.5 mm or if seat type mismatches.
  • ABS and stability control quirks from large tire diameter changes.
  • Speedometer error with big circumference changes.
  • Fastener issues from incorrect bolt length or thread pitch.

Using the wheel-tire calculator

The calculator compares Wheels from donor vehicle versus Installed on your vehicle. You can also test Custom wheel size and Custom tire size. When you change rim diameter, the tool updates tire diameter in the comparison.

  • Set Installed on to 2015 Audi RS 5.
  • Enter your verified current wheel and tire sizes from the door placard.
  • Choose a donor vehicle or enter a custom wheel size with diameter, width, and offset.
  • Adjust custom tire section width and aspect ratio until overall diameter is close to stock.
  • Watch inner clearance and outer poke deltas. Small changes are safer.

Gotchas to check before you buy

  • Caliper clearance. Some designs need more spoke-to-caliper room even if diameter fits.
  • Hub centricity. If wheel bore is larger than 66.5 mm, fit proper rings.
  • Bolt seat type. Audi often uses a specific seat style. Match the wheel, not the car.
  • Bolt length. Aftermarket wheels may need different shank length. Keep full thread engagement without bottoming out.
  • Tire stretch or bulge. Match tire width to wheel width for safe sidewall support.

Tools and helpful items

Next steps

  • Checklist: Read your door placard to confirm factory tire and wheel sizes.
  • Checklist: Verify bolt seat type and needed bolt length with the wheel seller.
  • Checklist: Set Installed on to your car and enter your verified sizes in the calculator.
  • Checklist: Test your target setup. Keep tire diameter change minimal. Aim for close to stock.
  • Checklist: Ensure inner clearance is safe and outer poke stays within the fender line.
  • Checklist: Plan for hub-centric rings if wheel bore exceeds 66.5 mm.
  • Checklist: Install with clean hubs. Hand start bolts. Torque in a star pattern to the OEM spec from your manual.
  • Checklist: Re-torque after 50 to 100 miles.
