Audi A5 Bolt Pattern: What Owners and Shoppers Need to Know

The bolt pattern on most modern Audi A5 models is 5×112, meaning five wheel bolts spaced on a 112 mm circle, but details can vary slightly by model year and performance variant, so checking exact specifications before buying wheels is essential. This article explains what that bolt pattern means, how it has evolved, how to verify it for your specific A5, and what else you must match—such as center bore and offset—when choosing new wheels.

Understanding the Audi A5 Bolt Pattern

The Audi A5 has been produced across several generations and body styles—coupe, Sportback, and cabriolet—yet its wheel bolt pattern has been remarkably consistent. For nearly all second-hand and new A5s on the road today, the standard bolt pattern is 5×112. Still, the details around hub bore, offset, and wheel size matter just as much when fitting aftermarket or winter wheels.

What “5×112” Actually Means

In wheel terminology, “bolt pattern” (or PCD—Pitch Circle Diameter) describes how the wheel attaches to the hub. For the Audi A5, 5×112 is the industry-standard way of writing its pattern.

The following list explains the meaning of “5×112” in practical terms for Audi A5 owners.

• 5 – The wheel is secured with five bolts (or studs/bolts, depending on design).
• 112 – The bolts sit on a circle with a diameter of 112 millimeters.
• Metric standard – The 112 value is always in millimeters, which is the norm for European cars like Audi.
• Compatibility key – Any replacement or aftermarket wheel must share this exact 5×112 pattern to mount correctly without adapters.

Together, these points show that “5×112” is not just a code—it’s the basic compatibility requirement that every wheel must meet to be safely fitted to an Audi A5.

Bolt Pattern by Audi A5 Generation and Variant

While rim diameter and width vary widely between trims and packages, Audi has largely standardized the A5’s bolt pattern to 5×112 across generations. Still, understanding the model-year context helps avoid mixing information from other Audi families that may differ in details such as offset or hub size.

First Generation (B8: 2007–2016)

The first-generation A5 (internal code B8), including the S5 versions, introduced the model line with a consistent wheel attachment standard in most markets.

The list below summarizes the key mounting specs that typically apply to first-generation Audi A5 models.

• Bolt pattern (PCD): 5×112
• Center bore (hub size): 66.6 mm (commonly specified as 66.5–66.6 mm)
• Fasteners: 5 wheel bolts (M14×1.5 thread on most European-spec models)
• Typical offsets (ET): Approximately ET28–ET45, depending on wheel width and trim
• Wheel sizes from factory: Commonly 17–19 inches, with S5 and special packages using wider and lower-offset wheels

For this generation, the constant 5×112 bolt pattern means many OEM and aftermarket wheels can be shared across different B8 A5 trims, provided offset, width, and center bore are also compatible.

Second Generation (B9: 2016–Present)

The second-generation A5 (B9), launched for the 2016/2017 model year depending on market, continued the 5×112 standard, ensuring backward compatibility with many Audi wheels from other models that use the same pattern.

The following list outlines the characteristic fitment details seen on most second-generation A5 and S5 variants.

• Bolt pattern (PCD): 5×112
• Center bore: 66.6 mm
• Fasteners: Typically M14×1.5 wheel bolts
• Typical offsets (ET): Around ET28–ET45, varying by trim, wheel width, and brake package
• Wheel sizes: Frequently 17–20 inches from the factory, with performance and appearance packages using larger diameters

This continued use of 5×112 makes wheel upgrades relatively straightforward for B9 A5 owners, so long as they keep an eye on offset, brake clearance, and load ratings.

Performance Models: S5 and RS 5

Performance-focused variants like the S5 and RS 5 also share the 5×112 pattern but may restrict wheel options due to larger brakes and more aggressive offsets.

The following list highlights considerations that set S5 and RS 5 fitment apart from base A5 trims, even though the bolt pattern remains 5×112.

• Bolt pattern: 5×112 across S5 and RS 5 models.
• Big brakes: Larger front calipers and discs, especially on RS 5, demand wheels with sufficient caliper clearance.
• Wider wheels: From the factory, performance models often have wider rims and lower offsets for a more aggressive stance.
• Offset sensitivity: Incorrect offset can cause rubbing or suspension interference more easily on these variants.
• Load rating: Wheels must be approved for the higher performance and weight of S/RS models.

Despite sharing the same 5×112 pattern, S5 and RS 5 owners often need to be more selective and rely on model-specific wheel fitment data to avoid brake and fender clearance issues.

Beyond Bolt Pattern: Other Critical Wheel Specs

Matching the 5×112 bolt pattern is only the first step. To safely and comfortably fit wheels to an Audi A5, other dimensions and ratings must also match or be carefully chosen, particularly center bore, offset, and overall diameter.

Center Bore (Hub Diameter)

The center bore ensures the wheel sits perfectly centered on the hub. Most modern A5s share the same hub size, simplifying the selection of direct-fit wheels.

The points below outline why center bore size is as important as the bolt pattern when choosing wheels for an Audi A5.

• Standard size: Most Audi A5 and S5 models use a 66.6 mm center bore.
• Hub-centric fit: OEM wheels are designed to be hub-centric, meaning the wheel centers on the hub, reducing vibration.
• Aftermarket wheels: Many aftermarket wheels have a larger universal bore and rely on hub-centric rings to adapt to 66.6 mm.
• Too-small bore: A wheel with a smaller center bore than 66.6 mm cannot be fitted without machining (not recommended for most users).
• Vibration risk: Using wheels that are not properly hub-centric can cause steering wheel vibration, especially at highway speeds.

Ensuring that the wheel either has a 66.6 mm bore or uses quality hub-centric rings is critical for smooth and safe operation on an Audi A5.

Offset (ET) and Width

Offset and width determine how far the wheel sits in or out relative to the fender and suspension. These values are crucial for handling and appearance, and they must be compatible with the car’s geometry.

The following list summarizes what Audi A5 owners should keep in mind regarding offset and width.

• Offset (ET): Measured in millimeters; positive ET means the mounting face is closer to the outside of the wheel.
• Factory range: A5 wheels typically fall in the ET28–ET45 region, varying with width and package.
• Too low an offset: Pushes the wheel outward, which can cause rubbing on fenders or require rolled arches.
• Too high an offset: Pulls the wheel inward, risking contact with suspension components or inner liners.
• Width considerations: Wider wheels magnify the impact of offset changes and may require different tire sizes.

Choosing wheels with an offset close to the original specification—and verifying clearance for your exact brake and suspension setup—is as important as matching the 5×112 bolt pattern itself.

Wheel Diameter and Tire Size

While bolt pattern and offset handle how the wheel mounts, overall wheel diameter and tire size affect ride quality, speedometer accuracy, and clearance. Audi offers multiple wheel diameters from the factory, which can guide safe upgrade choices.

The list below explains how to choose wheel and tire dimensions that work well with the Audi A5.

• Common factory diameters: 17″, 18″, 19″, and up to 20″ on higher trims or sport packages.
• Rolling diameter: Upgraded wheel and tire combos should maintain near-stock overall diameter to protect speedometer accuracy and driveline components.
• Profile vs. comfort: Larger wheels usually require lower-profile tires, which can reduce ride comfort and increase road noise.
• Winter setups: Many owners downsize to smaller wheels (e.g., 17″ or 18″) with higher-profile tires for winter, still using 5×112 and correct offset.
• Clearance check: Any change in diameter or tire width should be checked for clearance at full steering lock and over bumps.

Within reasonable limits, the A5 accepts a range of wheel sizes, but all must respect the 5×112 bolt pattern and remain close to factory rolling diameter and offset for safe everyday use.

How to Confirm Your Specific Audi A5 Bolt Pattern

Although the 5×112 specification is consistent across nearly all modern Audi A5s, direct verification is wise—especially if the car has a complex history, aftermarket hubs, or comes from a niche market.

Checking Documentation and Online Databases

Paperwork and official resources are the quickest way to verify factory specifications for your car, including bolt pattern and other fitment data.

The following list outlines the best places to confirm wheel specs for an Audi A5 without lifting a wrench.

• Owner’s manual: Often lists approved wheel sizes and may include bolt pattern and offset information.
• Service manual / workshop data: More technical documentation used by dealers and independent shops will list PCD and hub size.
• Door-jamb or fuel-flap sticker: Typically shows tire sizes and pressures; while it may not state PCD, it confirms OEM sizes to cross-reference.
• Online fitment databases: Reputable wheel and tire sites list bolt pattern, center bore, and offset by model year and trim.
• Audi dealer: Can look up factory wheel specs by VIN to confirm details for your specific vehicle.

Using documentation and reliable databases gives a strong baseline, which can then be confirmed physically if necessary for a car with non-standard parts.

Physical Measurement and Visual Checks

In rare cases—such as heavily modified vehicles or imported cars—measuring the bolt pattern directly adds certainty before buying wheels.

The steps below describe how enthusiasts or technicians might confirm a 5×112 pattern on an Audi A5.

• Count the bolts: Confirm there are five wheel bolts or stud locations.
• Measure PCD (5-lug): On a five-bolt hub, measure from the center of one bolt hole to the outer edge of the hole directly opposite, then compare to 112 mm.
• Check center bore: Use a caliper to measure the hub’s outer diameter; it should be about 66.6 mm on most A5s.
• Inspect wheel markings: OEM and many aftermarket wheels are stamped with their size, offset (e.g., “ET35”), and PCD (e.g., “5×112”).
• Confirm front and rear: Ensure both axles match, especially on cars with unknown modification history.

While most owners rely on documentation, these measurements offer a definitive confirmation that the car and the intended wheels share the 5×112 pattern and correct hub size.

Common Mistakes When Choosing Wheels for an Audi A5

Because 5×112 is a popular bolt pattern across Audi, Volkswagen, Mercedes-Benz, and others, many wheels appear to “fit” at a glance. However, subtle differences can cause safety or drivability issues if overlooked.

Overlooking Center Bore and Hub-Centric Rings

Many aftermarket wheels are drilled with a larger universal center bore and rely on rings to match specific cars like the Audi A5.

The following list highlights typical pitfalls involving center bore and hub-centric adapters.

• No hub-centric rings used: Can lead to vibrations even when the bolt pattern is correct.
• Cheap plastic rings: Low-quality rings may deform with heat or break during tire changes.
• Wrong ring size: Mismatched inner or outer diameter fails to properly center the wheel on the hub.
• Assuming “close enough”: A bore slightly too large without rings will not self-center when tightened.
• Mixing brands: Some wheel brands require specifically shaped rings for a secure fit.

Ensuring quality, correctly sized hub-centric rings—where needed—prevents vibrations and maintains the precise fit Audi designed for the A5.

Using Incorrect Offsets or Spacer Setups

Spacers and dramatic offset changes can create a more aggressive stance, but they introduce engineering trade-offs that many owners underestimate.

The list below covers risks associated with pushing fitment too far from factory specs on an A5.

• Fender rubbing: Wheels that sit too far out can contact the fender over bumps or when turning.
• Suspension interference: Excessively high offset or too-wide wheels can hit control arms or inner liners.
• Increased bearing load: Extreme spacing can put additional stress on wheel bearings and suspension components.
• Spacer quality: Poorly machined or non-hub-centric spacers can introduce vibration and safety issues.
• Legal and inspection concerns: In some regions, aggressive poke or unapproved spacers may fail inspection or be illegal.

Staying close to factory offset values and using high-quality, hub-centric spacers only when necessary helps preserve both safety and ride quality while maintaining correct 5×112 fitment.

Summary

The Audi A5 uses a 5×112 bolt pattern across its modern generations and performance variants, making it compatible with a wide range of OEM and aftermarket wheels that share this specification. For most owners, it is enough to know that the car takes five bolts arranged on a 112 mm circle, with a typical 66.6 mm center bore.

However, safe and trouble-free wheel fitment requires more than just matching 5×112. Ensuring the correct center bore or hub-centric rings, choosing an appropriate offset and wheel width, and keeping the overall rolling diameter near factory specifications are all essential steps. By confirming these details through documentation or direct measurement—and by avoiding common mistakes with offsets and spacers—Audi A5 owners can confidently select wheels that not only fit, but also preserve the car’s handling, comfort, and reliability.
