2021 Audi RS 5 Wheel Interchange

OEM wheel/tire sizes and fitment specs for the 2021 Audi RS 5.

Understanding Wheel Fitment for Your 2021 Audi RS 5

When it comes to swapping wheels on your Audi RS 5, there's a common misconception that all wheels labeled as "compatible" will fit perfectly. This can lead to confusion, especially if you're looking for that perfect look or performance enhancement.

Why It Seems True

Many people assume that if the wheels have the same bolt pattern or similar specs, they’ll fit. This belief often stems from online forums or advice from friends who may not have the complete picture. It’s easy to see how you might think, “If this wheel fits another model, it should fit mine too!”

What Is True

The reality is that fitment involves several critical specifications beyond just the bolt pattern. For your 2021 Audi RS 5, the OEM fitment specifications are:

  • Bolt pattern: 5x112
  • Center bore: 66.5 mm
  • Thread size: M14 x 1.5
  • Rim diameter: 20 in
  • Rim width: 9.0 in
  • Wheel offset: ET 26 mm
  • Backspacing: 5.52 in
  • Tire section width: 265 mm
  • Tire aspect ratio: 35%
  • Tire rim diameter: 19 in

These specifications are crucial for ensuring that your wheels fit correctly and maintain safe driving conditions.

Implications

Choosing wheels without considering these details can lead to poor handling, increased tire wear, or even dangerous driving situations. For example, a wheel with the wrong offset might cause your tires to rub against the suspension components or fenders, which is not ideal.

Quick Tests

To ensure you’re selecting the right wheels, here’s a quick recap of what to check:

  • Verify the bolt pattern matches (5x112 for your RS 5).
  • Check the center bore to ensure it fits snugly on your hub (66.5 mm).
  • Confirm the offset and backspacing are appropriate for your vehicle’s design.
  • Use our wheel fitment calculator to compare wheels from donor vehicles to your Audi RS 5.

If you’re ever unsure, it’s best to consult OEM sources or use the calculator to double-check specifications. It’s a simple way to give yourself peace of mind.
