What Stud Pattern Is an Audi A4?
The wheel stud pattern (also called PCD) for most modern Audi A4 models is 5×112, meaning five wheel bolts arranged on a 112 mm diameter circle. However, exact specifications can vary slightly by model year and generation, so it is important to confirm for your specific car before buying wheels.

Understanding the Audi A4 Wheel Stud Pattern
The question of “what stud pattern is an Audi A4?” arises most often when owners are shopping for new wheels, winter sets, or second-hand rims. While the general rule for recent A4s is straightforward—5×112—there are additional details such as center bore size and offset that matter just as much as the stud pattern itself.
Core Specification: PCD, Center Bore and Bolt Type
On an Audi A4, the stud pattern is only one part of the wheel fitment equation. Owners need to understand three key parameters: PCD (the bolt pattern), the center bore, and the type and size of the wheel bolts.
PCD (Pitch Circle Diameter): The Stud Pattern
Across the B6 (facelift), B7, B8 and B9 generations—covering the early 2000s through current models—the Audi A4 has standardized on a 5×112 pattern for passenger models in most global markets.
The following list explains how that pattern is defined and used on the Audi A4.
- Number of bolts: 5 wheel bolts (not studs and nuts; Audi uses bolts)
- PCD value: 112 mm diameter circle (hence “5×112”)
- Generations commonly using 5×112:
- B6: late production years (approx. 2002–2004, region-dependent)
- B7: 2004–2008
- B8: 2008–2015
- B9: 2015–present (A4, S4 and most variants)
- Typical associated models: A4 sedan/Avant, A4 allroad, S4; most share 5×112 within the same generation
- Aftermarket compatibility: Many Mercedes-Benz, VW, and other VAG-platform wheels also use 5×112, but offset and center bore still must be checked
In practice, if you have an Audi A4 from roughly the mid‑2000s onward, it almost certainly uses a 5×112 pattern, making it compatible with a large pool of OEM and aftermarket wheels designed for that standard.
Center Bore: Keeping the Wheel Properly Centered
Beyond the stud pattern, the center bore (the diameter of the hole in the middle of the wheel that fits over the hub) is crucial. On modern Audi A4 models, the typical center bore is around 66.5 mm.
The following list breaks down what you should know about center bore on an Audi A4.
- Standard size: Approximately 66.5 mm on recent A4 generations (B8 and B9)
- Function: Ensures the wheel is hub-centric, meaning the wheel is centered on the hub, not only by the bolts
- Aftermarket wheels: Often have a larger bore and use hub-centric rings to adapt to 66.5 mm
- Older OEM wheels: Some earlier Volkswagen/Audi wheels use a smaller 57.1 mm bore and will not fit without machining
- Vibration risk: Using a wheel with the wrong center bore or without proper hub-centric rings can cause vibration even if the stud pattern is correct
Matching or correctly adapting the center bore is just as important as matching the 5×112 pattern, especially for comfort and steering precision at motorway speeds.
Wheel Bolts: Thread, Seat Type and Length
Audi A4 models use wheel bolts rather than wheel studs and nuts, and the details of those bolts matter for safety.
The list below outlines the main characteristics of Audi A4 wheel bolts.
- Thread size: Typically M14×1.5 on recent A4 generations (14 mm diameter, 1.5 mm thread pitch)
- Seat type: Usually a ball (radius) seat on OEM wheels, not a conical seat
- Bolt length: Varies depending on wheel design and whether spacers are used; using incorrect length can be dangerous
- Torque spec: Commonly in the range of 120 Nm (check owner’s manual for the exact value for your model/year)
- Aftermarket wheels: May require conical-seat bolts, so mixing factory bolts with some aftermarket rims can be incorrect even if the pattern is 5×112
Ensuring you use the correct seat type, thread size, and length, in addition to the right pattern, is essential to avoid loose wheels, damaged mounting surfaces, or unsafe bolt engagement.
Exceptions and Older Generations
While 5×112 is the norm for modern A4s, some earlier Audi A4 models and regional variants can differ slightly, particularly in related fitment specs like offset and center bore, and very early A4s shared more with older Volkswagen platforms.
Early A4 (B5) and Transition to 5×112
The first-generation A4 (B5, introduced in the mid‑1990s) historically used a different fitment in some markets before Audi standardized across platforms.
This list clarifies what owners of older A4s should keep in mind.
- B5 A4 (mid‑1990s to early 2000s): Often cited with a 5×112 pattern in later years, but offsets, center bore, and brake clearances can differ from modern cars
- Brake and hub upgrades: Many older A4s have had brake or hub conversions, which can change effective fitment
- Regional differences: Some fitment data online is region-specific and may not match your exact configuration
- Used-wheel risks: Buying older OEM wheels based purely on “they’re from an A4” can be misleading if you don’t confirm specs
- Verification: Always cross-check wheel specs with a VIN-based parts catalog or a reputable wheel fitment database when dealing with 1990s–early 2000s A4s
Because of these nuances, owners of older A4 models should double-check full wheel specifications and not rely solely on the general 5×112 rule-of-thumb.
Offset (ET) and Width: Why Pattern Alone Isn’t Enough
Even when the stud pattern is correct, the wrong offset or wheel width can cause rubbing, poor handling, or clearance issues with brakes and suspension components.
Typical Audi A4 Offset Ranges
The wheel offset (often marked “ET”) controls how far inboard or outboard the wheel sits relative to the hub.
The following list shows the general offset landscape for modern A4 models.
- Factory offsets: Often in the range of ET +35 to +47 depending on wheel width and trim
- Narrow OEM wheels: Tend toward higher offsets (e.g., ET45–ET47)
- Wider sport wheels: Usually slightly lower offsets (e.g., ET35–ET42) for a more flush look
- Aftermarket fitment: Commonly targets ET30–ET40 on 8.0–8.5J wheels for a visually “full” stance without major rubbing, assuming appropriate tire sizes
- Spacers: Sometimes used to effectively lower offset for aesthetic or brake-clearance reasons, but require longer, correct-spec bolts
Matching the 5×112 pattern but ignoring offset can result in a wheel that technically bolts on but either sits too far inside (looking sunken and risking suspension contact) or too far outside, causing fender rubbing and spray issues.
Wheel Width and Tire Size
Wheel width and tire choice also play a role in how well a wheel with the correct pattern actually works on an Audi A4.
The list below summarizes common combinations found on recent A4s.
- Common OEM widths: 7.5J, 8.0J and sometimes 8.5J for sport or S4 models
- Typical tire sizes:
- 17″: around 225/50 R17
- 18″: around 245/40 R18
- 19″: around 255/35 R19 (depending on trim and region)
- Allroad/off-road style: Often slightly higher profiles for comfort and light off-pavement use
- Aftermarket upsizing: Many owners move to 18″ or 19″ with wider tires, but must watch for inner and outer clearance
- Suspension changes: Lowered cars have less room, so even with the correct 5×112 pattern, a borderline offset/width combo can rub
Considering width and tire sizing alongside the stud pattern ensures the wheels not only fit on paper but also function well in daily driving and under load.
How to Confirm the Stud Pattern on Your Specific Audi A4
Despite the general rule of 5×112, confirming the exact wheel specs for your particular car is a sensible step before spending money on rims or tires.
Practical Ways to Check
There are several reliable ways to verify your Audi A4’s stud pattern and related specifications without relying solely on generic assumptions.
The list below outlines the most practical methods owners can use.
- Owner’s manual: Check the wheels and tires section; it often lists size, offset, and sometimes bolt pattern.
- Inside of the wheel: Remove one wheel and look for cast-in markings such as “7.5Jx17 ET45 5×112.”
- Fuel flap or door jamb sticker: These often display tire sizes and, less commonly, wheel dimensions that can be cross-referenced.
- VIN-based parts catalog: An Audi dealer or online OEM parts database can pull the original wheel specs using your VIN.
- Reputable fitment databases: Specialist wheel sites maintain updated fitment guides by model year and trim.
Using one or more of these methods to verify that your A4 uses 5×112—and to confirm center bore and offset—reduces the risk of buying incompatible wheels.
Key Takeaways: Stud Pattern for Audi A4 Models
The central point is straightforward: virtually all modern Audi A4 models use a 5×112 wheel stud pattern, but proper fitment requires a broader view that includes center bore, offset, width, and the correct wheel bolts.
The following list summarizes the main facts owners should remember.
- Stud pattern (PCD): 5×112 on the vast majority of A4 models from the early‑2000s onward
- Center bore: Typically around 66.5 mm on recent generations (B8, B9)
- Bolt type: M14×1.5 wheel bolts with ball-seat heads on OEM wheels
- Offset range: Commonly ET35–ET47, depending on wheel width and trim
- Verification: Always confirm against your specific model year, trim, and VIN before purchasing wheels
By keeping these points in mind, Audi A4 owners can confidently select compatible wheels that maintain safety, ride quality, and the car’s intended handling characteristics.
Summary
Most Audi A4s—from mid‑2000s models to current B9 versions—use a 5×112 wheel stud pattern with a hub bore around 66.5 mm and M14×1.5 ball-seat wheel bolts. While 5×112 is the crucial headline specification, safe and proper wheel selection also depends on center bore, offset, wheel width, and the correct bolt type and length. Because of minor differences across generations and possible modifications, owners are best served by confirming exact specs via the owner’s manual, wheel markings, or a VIN-based parts catalog before buying new or used wheels.
