What Is the Bolt Pattern on the Audi S5?

The Audi S5 typically uses a 5×112 bolt pattern across all generations, meaning five wheel bolts arranged on a 112 mm pitch circle diameter. However, correct fitment also depends on center bore and offset, which vary slightly by model year and body style.

Understanding the Audi S5 Bolt Pattern

The bolt pattern is one of the key measurements needed when choosing aftermarket or replacement wheels for an Audi S5. While the 5×112 pattern is consistent, details such as center bore, offset (ET), and stock wheel sizes differ between the B8, B8.5, and B9 generations, as well as between coupe, Sportback, and Cabriolet variants.

Core Wheel Specs for the Audi S5

Bolt Pattern Explained

On the Audi S5, “5×112” means that the wheel mounts with five bolts (or lug holes) arranged evenly around a circle that is 112 millimeters in diameter. This pattern is standard across virtually all modern Audi S5 models, including:

  • First-generation S5 (B8, 2008–2012)
  • Facelift S5 (B8.5, 2013–2016)
  • Second-generation S5 (B9, 2017–present, including recent 2024–2025 models)

Knowing that all these generations share the same 5×112 pattern simplifies wheel selection, but other parameters must still match for safe and proper fitment.

Typical Center Bore

The center bore is the diameter of the hub opening in the wheel, which centers the wheel on the hub. For most modern Audi S5 models, the center bore is:

  • 66.6 mm for B8/B8.5 S5 (2008–2016)
  • 66.6 mm for B9 S5 (2017–present)

Most OEM and many aftermarket wheels for the S5 are hub-centric at 66.6 mm. If the wheel has a larger center bore, hub-centric rings are commonly used to adapt it correctly to the Audi hub.

Stock Wheel Sizes and Offset Ranges

Although the bolt pattern remains 5×112, Audi S5 models come from the factory with different wheel widths, diameters, and offsets (ET). The offset is the distance between the hub mounting surface and the wheel’s centerline, measured in millimeters. Typical factory configurations include:

  • B8/B8.5 S5 (2008–2016): generally 18″–19″ wheels, offsets commonly around ET32–ET43 depending on design and package.
  • B9 S5 (2017–present): commonly 18″–20″ wheels, with offsets also typically in the ET30–ET40 range, varying by trim (Premium, Premium Plus, Prestige) and performance packages.

These ranges are approximate; exact figures vary by market and wheel design. Checking the specific wheel part numbers or the label inside the driver’s door jamb is the best way to confirm the factory specification for a particular car.

Generational Overview: S5 Bolt Pattern by Model

B8 & B8.5 Audi S5 (2008–2016)

The first-generation S5 arrived as a coupe in the late 2000s and later expanded to Cabriolet and Sportback forms. Across these versions, the bolt pattern remained consistent.

  • Bolt pattern: 5×112
  • Center bore: 66.6 mm
  • Typical OEM wheel diameters: 18″ and 19″
  • Typical OEM widths: 8.5J–9.0J
  • Typical offsets (ET): roughly ET29–ET43 depending on style/package

Whether coupe, Cabriolet, or Sportback, the use of 5×112 and a 66.6 mm center bore is common, giving owners some flexibility to swap wheels among these variants, provided offsets and tire sizes remain appropriate.

B9 Audi S5 (2017–Present, Including Recent Model Years)

The second-generation B9 S5, including refreshed models up to current production, continues Audi’s standardization around 5×112. The car typically ships with larger wheel options, reflecting modern styling and performance trends.

  • Bolt pattern: 5×112
  • Center bore: 66.6 mm
  • Typical OEM wheel diameters: 18″, 19″, and 20″
  • Typical OEM widths: around 8.0J–9.0J
  • Typical offsets (ET): approximately ET30–ET40, depending on design and package (e.g., S line, Black Optic)

This continuity simplifies upgrading wheels across B9 model years, as long as offset, width, and tire size are kept within safe limits that avoid rubbing and maintain proper suspension and steering geometry.

How to Confirm Your Specific S5’s Bolt Pattern and Wheel Specs

Checking On the Car and in Documentation

Although the Audi S5’s bolt pattern is effectively standardized at 5×112, verifying the rest of the wheel data on an individual vehicle remains important, especially if it has been modified.

The following methods are commonly used to confirm wheel specifications on an Audi S5:

  • Owner’s manual: Lists recommended wheel and tire sizes, including diameter and width.
  • Door jamb sticker: Usually shows tire and wheel size information for factory configurations.
  • Back of the wheel: Genuine Audi wheels typically have markings indicating size (e.g., 8.5Jx19), offset (e.g., ET32), and part number.
  • VIN-based lookup: An Audi dealer or reputable parts database can use the vehicle’s VIN to look up original equipment wheel data.

Using these sources ensures that any new wheel choice maintains the car’s performance, safety, and intended ride quality, rather than relying on estimates or generic fitment charts.

Practical Considerations When Choosing Wheels for an Audi S5

Beyond the Bolt Pattern: What Else Matters

Matching the 5×112 bolt pattern is only the first step. To avoid vibration, rubbing, or mechanical interference, several other parameters must be considered.

Key considerations when selecting wheels for an Audi S5 include:

  1. Center bore compatibility: Prefer wheels with a 66.6 mm bore or use hub-centric rings if the bore is larger.
  2. Offset (ET): Staying close to OEM offsets (typically ET30–ET40) helps maintain proper suspension geometry and clearance.
  3. Wheel width: Wider wheels can improve grip but may require more precise offset choices to avoid fender or suspension contact.
  4. Tire size: Overall diameter should remain close to stock to keep speedometer and driver-assistance systems accurate.
  5. Brake clearance: Performance models with larger brakes need sufficient spoke and barrel clearance around calipers.

Taking all of these factors into account ensures that a wheel swap is not just visually appealing but mechanically sound and compliant with the vehicle’s design tolerances.

Summary

The Audi S5, from the first B8 generation through the current B9 models, uses a 5×112 bolt pattern, paired with a 66.6 mm center bore on virtually all versions. While this shared pattern makes wheel selection more straightforward, safe and optimal fitment still depends on matching offset, width, and tire sizes to the vehicle’s specifications. Verifying details via the owner’s manual, door sticker, wheel markings, or VIN lookup is the most reliable way to ensure that any new wheels fit your specific S5 correctly.
