Audi Bolt Pattern Guide: Lug Pattern Specifications Across Models – Find the Perfect Fit for Your Wheels
You’ve found the perfect set of wheels for your Audi—stunning design, flawless finish, exactly the look you’ve been chasing—but one critical question lingers: “Will they actually bolt on?” The answer lies in a single, crucial number: your Audi’s bolt pattern. Getting it wrong means a set of wheels that simply won’t fit, wasted money, and frustration. But understanding bolt patterns isn’t just about matching numbers—it’s about preserving your Audi’s handling, safety, and Quattro performance.
TLDR: Most modern Audis use a 5x112mm bolt pattern, while older models may use 5x100mm or even 4x100mm. This guide provides a comprehensive model-by-model breakdown of bolt patterns, center bore sizes, lug nut specs, and wheel fitment essentials to help you find the perfect set of wheels for your Audi.
Your Audi’s bolt pattern—also known as the lug pattern or PCD (Pitch Circle Diameter)—is the diameter of an imaginary circle that passes through the center of each lug hole. It’s the foundation of wheel fitment and a critical factor in maintaining your vehicle’s safety and performance. Forgetting the center bore or lug nut specifications can lead to vibration, wobble, and even wheel separation. It’s not just about aesthetics; it’s about ensuring your wheels are securely and safely mounted.
Here’s a crucial safety reminder that many owners overlook: The bolt pattern is only one part of the puzzle. Even if the bolt pattern matches, the center bore (the hole in the center of the wheel that fits over the hub) must also match—or you’ll need hub-centric rings. Most Audi models use a 57.1mm center bore. If your aftermarket wheels have a larger center bore, you must use hub-centric rings to center the wheel properly.
Key Takeaways
- Know your pattern: Most modern Audis use 5x112mm; older models may use 5x100mm or 4x100mm
- Center bore matters: Most Audis use 57.1mm center bore—this must match or be adapted with hub-centric rings
- Lug nuts are specific: Audi uses ball-seat lug bolts (not cone-seat like many aftermarket wheels require)
- Check your model: Different model years and trims have different specifications—always verify for your exact vehicle
- Wheel compatibility: 5×112 wheels from other brands may not fit if they have a different center bore or require different lug bolts
- Test fit always: Even with correct specifications, always test-fit a wheel before committing to a full set
Understanding Bolt Patterns
Before we dive into the specific numbers, let’s decode what those numbers mean.
The Bolt Pattern (PCD)
The bolt pattern is expressed as Number of Lugs x PCD (mm) . For example, “5×112” means:
- 5: Five lug holes
- 112: 112mm diameter of the circle that passes through the center of each lug hole
Center Bore
The center bore is the diameter of the large hole in the center of the wheel that fits over the hub. Most Audi models use:
- 57.1mm (standard for most modern Audis)
- Some older models use 56.1mm or 57.1mm, depending on the platform.
Why it matters: The center bore is load-bearing—it centers the wheel on the hub. If the center bore is too large, the wheel can be off-center, causing vibrations and potential wheel failure. Hub-centric rings adapt a larger center bore to your Audi’s 57.1mm hub.
Lug Bolts vs. Lug Nuts
- Audi uses lug bolts: The bolt screws into the hub, not a lug nut.
- Seat type: Audi uses a ball seat (radiused) design. Most aftermarket wheels use a cone seat (tapered) design. You must use the correct lug bolts for your wheels.

Bolt pattern and center bore distribution across Audi models
Lug Bolts vs. Lug Nuts
Audi Uses Lug Bolts
Unlike many other brands that use lug nuts, Audi uses lug bolts. The bolt screws into the wheel hub, and the wheel is sandwiched between the bolt head and the hub.
Ball Seat vs. Cone Seat
- Audi ball seat (radiused): The wheel’s lug holes have a rounded, ball-shaped recess.
- Aftermarket cone seat (tapered): The wheel’s lug holes have a conical, tapered recess.
Important: You must use the correct seat type. Using ball seat bolts on cone seat wheels (or vice versa) will result in improper clamping force and potential wheel failure.
Recessed vs. Extended Bolts
- Recessed: The bolt head sits below the wheel surface (most common).
- Extended: The bolt head protrudes above the wheel surface (some aftermarket wheels require these).
Lug Nut Torque Specifications
| Model | Lug Thread Size | Torque (ft-lbs) | Torque (Nm) |
|---|---|---|---|
| All 5×112 Models | M14 x 1.5 | 90 | 120 |
| Q7 (4L) 5×130 | M14 x 1.5 | 90 | 120 |
| TT (8N) 5×100 | M14 x 1.5 | 90 | 120 |
Always torque lug bolts to the manufacturer’s specified value using a calibrated torque wrench.
How to Measure Your Bolt Pattern
If you don’t have access to a spec sheet, you can measure your bolt pattern yourself.
Tools Needed
- Caliper (or a ruler)
- Measuring tape (accurate to 1/16″)
Step-by-Step
For 5-Lug Wheels:
- Find the center of one lug hole (the center, not the edge).
- Measure to the center of the lug hole directly across from it (not adjacent).
- This distance is the PCD (Pitch Circle Diameter) in millimeters.
Alternatively:
- Measure the distance from the center of one lug hole to the center of an adjacent lug hole (not directly across).
- Multiply that distance by 1.525 (the 5-lug pattern constant).
Common Measurements
- 112mm: Bolt holes will be approximately 68mm apart (adjacent).
- 100mm: Bolt holes will be approximately 61mm apart (adjacent).
- 130mm: Bolt holes will be approximately 79mm apart (adjacent).
Frequently Asked Questions
Can I use 5×112 wheels from another brand?
Possibly. The bolt pattern matches, but you must also check:
- Center bore: Your Audi uses 57.1mm. If the wheel has a larger center bore, you’ll need hub-centric rings.
- Lug seat: Audi uses ball seat bolts. Most aftermarket wheels use cone seats. You’ll need to use the correct lug bolts.
- Offset: The wheel’s offset (ET) must be appropriate for your Audi.
Will 5×114.3 (5×4.5″) wheels fit my Audi?
No. The bolt pattern must be an exact match. 5×114.3 wheels are about 2.3mm different (smaller or larger, depending on the measurement) and won’t bolt on safely.
What if I use wheel adapters?
Wheel adapters can allow you to use a different bolt pattern, but they add unsprung weight, change the wheel offset, and can put additional stress on your wheel bearings. Always use high-quality adapters and have a professional install them.
Can I use wheel spacers?
Yes, but they must be:
- Hub-centric (fitting over the 57.1mm hub).
- Safe (not exceeding the recommended thickness).
- Installed with longer lug bolts (if they are thick).
What is the correct lug nut torque for my Audi?
90 ft-lbs (120 Nm) for all models with M14 x 1.5 lug bolts. Always use a calibrated torque wrench and tighten in a star pattern.
Safety Checklist
- [ ] Bolt pattern matches exactly (5×112, 5×100, or 5×130)
- [ ] Center bore matches (57.1mm or is adapted with hub-centric rings)
- [ ] Lug seat type matches (ball seat for OEM, cone seat for aftermarket)
- [ ] Lug bolts are long enough for the wheel’s mounting pad thickness
- [ ] Lug bolts are torqued to 90 ft-lbs in the correct star pattern
- [ ] Wheel adapter rings are installed (if using aftermarket wheels)
- [ ] Wheel spacers are hub-centric (if used)
- [ ] New lug bolts are the correct length (longer if spacers are used)
