Understanding Wheel Fitment for Your 2019 Audi A5

When it comes to wheel fitment, many DIY owners and technicians have a few misconceptions. One common belief is that any wheel that fits the bolt pattern will work on your vehicle.

Why This Misconception Seems True

It makes sense, right? If the bolt pattern matches, it should fit. But, there are other important factors to consider, such as wheel offset, backspacing, and center bore. These specifications play a crucial role in how the wheel interacts with your vehicle's suspension and brakes.

What is True

For your 2019 Audi A5, the known OEM fitment specifications are:

  • Bolt pattern: 5x112
  • Center bore: 66.5 mm
  • Thread size: M14 x 1.5
  • Rim diameter: 17 inches
  • Rim width: 7.5 inches
  • Wheel offset: 29 mm
  • Backspacing: 4.89 inches
  • Tire section width: 225 mm
  • Tire aspect ratio: 50%

These specifications indicate that it's not just the bolt pattern that matters. Each measurement contributes to how the wheel fits your car's overall dynamics.

Implications of Incorrect Fitment

If you choose a wheel that doesn't match these specifications, you may encounter issues like poor handling, brake interference, or even tire damage. Therefore, understanding these nuances is key to ensuring your safety and maintaining your vehicle’s performance.

Quick Tests to Ensure Compatibility

Here are a couple of quick tests you can do:

  • Check the bolt pattern: Ensure it is 5x112.
  • Measure the center bore: It should be exactly 66.5 mm to fit snugly on the hub.
  • Examine the offset: Make sure it’s around 29 mm to avoid clearance issues.
