What Is the Bolt Pattern on a 2014 Audi A4?

The standard bolt pattern for a 2014 Audi A4 (B8/B8.5 generation) is 5×112, meaning five wheel bolts arranged on a 112 mm pitch circle diameter (PCD). In most trims and markets, that pattern is consistent across sedans and Avants, though wheel size, offset, and center bore can vary.

Understanding the 2014 Audi A4 Wheel Bolt Pattern

The question of bolt pattern on a 2014 Audi A4 usually comes up when owners are shopping for aftermarket wheels, winter setups, or considering swapping wheels from another vehicle. While “5×112” is a simple specification, it interacts with offset, center bore, and bolt type, all of which need to match or be correctly adapted for safe and vibration-free driving.

The Core Specification: 5×112

For the 2014 Audi A4, which is part of the B8/B8.5 platform sold in North America and Europe, the vast majority of models share the same basic wheel attachment standard:

The following list outlines the key elements of the bolt pattern specification for a 2014 Audi A4.

• Bolt pattern (PCD): 5×112 – five bolts on a 112 mm circle.
• Thread size: M14 x 1.5 – 14 mm diameter bolts with a 1.5 mm thread pitch.
• Center bore (hub bore): 66.6 mm – the diameter of the hub opening in the wheel.
• Bolt type: Typically ball-seat wheel bolts (not conical), as is standard on most OEM Audi wheels.
• Common OEM wheel diameters: Generally 16″, 17″, or 18″ depending on trim and package.

Taken together, these specs mean that although many wheels may share a 5×112 bolt pattern, they must also match thread size, seat type, and hub bore—or be correctly adapted—to be safely used on a 2014 Audi A4.

Why the Bolt Pattern Matters

Knowing the bolt pattern is essential whenever you replace or upgrade wheels, but it is only one part of ensuring compatibility. A wheel that fits the bolt pattern but not the center bore or offset can create issues ranging from steering vibrations to premature suspension wear or even unsafe handling.

Compatibility With Other Vehicles

Owners often want to know if wheels from other Volkswagens, Audis, or even Mercedes-Benz models will fit their 2014 Audi A4. Many modern German cars share the 5×112 pattern, but that does not guarantee a direct fit.

The following list describes common compatibility considerations when using wheels from other vehicles on a 2014 Audi A4.

• Same 5×112 pattern: Many Audi, VW, and Mercedes-Benz wheels use 5×112, which is a good starting point.
• Center bore differences: Some manufacturers use smaller or larger hub bores; hub-centric rings may be needed to adapt.
• Offset (ET) variations: Even with 5×112, an offset that is too high or too low can make wheels rub or sit incorrectly.
• Bolt seat profile: Audi OEM wheels typically use ball-seat bolts; aftermarket wheels may use conical seats, requiring different hardware.
• Brake clearance: Larger brake packages (for example on performance trims) can limit how small or how curved the wheel design can be.

These factors mean that while the shared 5×112 pattern opens up many options, you should always verify the full wheel specification rather than relying on bolt pattern alone.

Offset, Width, and Center Bore: The Rest of the Fitment Puzzle

Once you know the 5×112 bolt pattern is correct, the next step is confirming offset, wheel width, and hub bore so that the new wheels sit properly, clear the brakes and fenders, and avoid vibration.

Typical OEM Fitment Ranges for a 2014 Audi A4

Factory wheels for the 2014 A4 generally follow a fairly narrow range of fitment, which can serve as a safe reference if you are choosing aftermarket wheels.

The following list provides typical OEM-style wheel specs seen on 2014 Audi A4 models (excluding extreme aftermarket setups).

• Wheel diameter: Around 16″ to 18″ on most trims; some sport or S line packages may use 18″.
• Wheel width: Commonly 7.5J to 8.5J (7.5 to 8.5 inches wide).
• Offset (ET): Typically in the ET35–ET47 range, depending on model and wheel style.
• Center bore: 66.6 mm, matching the Audi B8/B8.5 hub.
• Load rating: OEM or high-quality aftermarket wheels are designed to support the vehicle’s curb weight and dynamic loads.

Staying within or close to these ranges generally ensures worry-free fitment, though aggressive or custom setups may deliberately push beyond them and require careful test-fitting.

Practical Tips for Buying or Swapping Wheels

When shopping for wheels—whether used OEM or aftermarket—it’s important to verify more than just the bolt pattern. Mismatches in any of the critical dimensions can cause vibrations, uneven tire wear, or even safety issues under heavy braking or at high speed.

Steps to Confirm Wheel Fitment on a 2014 Audi A4

The next list outlines a practical checklist you can follow before committing to new or used wheels for your 2014 Audi A4.

1. Confirm bolt pattern: Ensure the wheel is 5×112; anything else will not mount properly on the hub.
2. Check center bore: Look for a 66.6 mm hub bore; if the bore is larger, quality hub-centric rings can adapt it; if smaller, the wheel will not fit.
3. Match bolt seat and thread: Verify that the wheel uses ball-seat hardware compatible with M14 x 1.5 bolts, or use the correct bolt type provided by the wheel manufacturer.
4. Verify offset and width: Compare the new wheel’s ET and width to OEM specs to avoid rubbing on suspension components or fenders.
5. Check brake clearance: Test-fit if possible, especially if you have larger brakes or are downsizing wheel diameter for winter tires.
6. Inspect used wheels: Look for cracks, bends, or corrosion, especially on the inner barrel, before installation.
7. Re-torque after driving: After mounting new wheels, re-torque the wheel bolts to manufacturer spec after 50–100 km (30–60 miles).

Following these steps helps ensure that a set of wheels that matches the 5×112 pattern will also perform safely and comfortably on your 2014 Audi A4.

Summary

The 2014 Audi A4 uses a 5×112 bolt pattern, paired with M14 x 1.5 wheel bolts and a 66.6 mm center bore. While that 5×112 specification opens the door to many OEM and aftermarket wheel options, safe fitment also depends on matching offset, hub bore, bolt seat type, and brake clearance. Verifying all of these parameters before buying or installing wheels ensures your A4 retains stable handling, avoids vibrations, and meets safety standards on the road.
