Center-bore records disagree (target year-level hub 66.6 mm vs trim range 66.5–66.5 mm; donor year-level hub 66.6 mm vs trim range 66.5–66.5 mm). Unqualified overlap is not claimed until the conflict is resolved. Approximate position vs the mid OEM package: outer change -1.17 mm, inner change -5.18 mm. This uses aggregated width/offset ranges, not a specific wheel.

Understanding Wheel Fitment for Your 2008 Audi S5
When it comes to upgrading or replacing wheels on your 2008 Audi S5, there are some common misconceptions to clear up. Many DIY owners and technicians find themselves confused about what wheels will fit their vehicle. Let’s dive in and clarify this step by step.
Misconception: Any 5x112 Wheel Will Fit
It's easy to assume that if a wheel has the same bolt pattern, it will fit your Audi S5. After all, the bolt pattern for the S5 is 5x112, which is common among several vehicles. However, there's much more to consider.
Why It Seems True
This belief stems from the idea that matching bolt patterns is the main requirement for fitting wheels. Many enthusiasts see a wheel with the same bolt pattern and think they can just install it. While the bolt pattern is crucial, it’s only part of the equation.
What Is True
In addition to the 5x112 bolt pattern, your S5 has specific requirements for center bore, offset, and other dimensions. The center bore is 66.6 mm, and the wheel offset is 29 mm. These factors ensure the wheels sit properly on your vehicle, maintaining safety and performance.
Implications
Choosing wheels that don’t meet these specifications can lead to issues like improper fitment, handling problems, or even safety risks. It’s essential to verify all measurements before making a purchase. Think of it as a puzzle–every piece needs to fit just right.
Quick Tests
Here are a few quick tests you can perform to ensure your wheels will fit:
Check the bolt pattern: Make sure it’s 5x112.
Measure the center bore: It should be 66.6 mm.
Verify the offset: Look for a wheel with an offset close to 29 mm.
By understanding the complete picture of wheel fitment for your 2008 Audi S5, you'll be better equipped to make informed choices. Clear up any confusion you have, and you’ll be well on your way to enhancing your vehicle.
Methodology and sources
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
Bolt pattern / PCD
Center bore direction (donor wheel bore must not be smaller than the hub)
Wheel diameter, width, and offset against known OEM ranges
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
