OEM wheel and tire fitment specs for the 2013 Audi S4, including bolt pattern (PCD), center bore diameter, thread size, rim diameter, rim width, wheel offset, and backspacing.
Recorded OEM specifications for the 2013 Audi S4, donor years with overlapping ranges, and a calculator to compare a selected wheel. Range overlap is not a guaranteed fit.
Multiple OEM configurations exist for this vehicle. Fitment can vary by trim, brakes, and factory wheel package – confirm your exact setup before buying.
Center-bore records disagree: year-level hub 66.6 mm vs trim range 66.5–66.5 mm. Interchange below does not treat this as an unqualified match.

Donor vehicles with overlapping OEM specs
These are vehicle-year records whose recorded OEM ranges overlap this 2013 Audi S4. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 188 donor years. Listed 24 eligible overlaps (not all evaluated years are compatible). Showing all listed.
Wheel geometryOEM width/offset ranges overlap (not a specific wheel)
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 57.1–66.5 mm). Unqualified overlap is not claimed until the conflict is resolved. Approximate position vs the mid OEM package: outer change -0.17 mm, inner change -6.18 mm. This uses aggregated width/offset ranges, not a specific wheel.
Dataset suggestionHub-centric rings ≈ 66.6 → 66.5 mm – not a verified installation requirement.
Hub-centric rings of about 66.6 → 66.5 mm mm may be relevant if the wheel bore is larger than the hub; clearance is not verified. Donor width/offset sits outside the known OEM envelope for this vehicle.

Understanding Wheel Fitment for Your 2013 Audi S4
So, you’re looking into wheel fitment for your 2013 Audi S4? You might be feeling a bit overwhelmed by all the specs and jargon out there. Let's clarify some common misconceptions and help you get a clear picture.
Misconception: All Wheels Fit All Cars
It’s easy to think that any wheel can fit your car as long as it looks good. But that's not the case at all. Each vehicle has specific requirements for its wheels.
Why It Seems True
Many people assume that a wheel's appearance is the only factor that matters. After all, if the bolt pattern seems right, why wouldn’t it fit? It's a common scenario where visual appeal overshadows the technical details.
What Is True
For your 2013 Audi S4, there are specific measurements you need to consider. Here’s a quick recap of the OEM specifications:
Bolt pattern: 5x112
Center bore: 66.6 mm
Thread size: M14 x 1.5
Rim diameter: 18 inches
Rim width: 8.0 inches
Wheel offset: 47 mm
Backspacing: 5.85 inches
Tire section width: 245 mm
Tire aspect ratio: 40%
Tire rim diameter: 18 inches
These specs are crucial for ensuring that your wheels fit properly and safely on your vehicle.
Implications
Using wheels that don’t match these specifications can lead to various issues. You might face problems with handling, safety, or even tire wear. It’s important to stick to the recommended fitment for optimal performance.
Quick Tests to Confirm Fitment
Want to double-check your options? Here are a few quick tests you can perform:
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.
