Audi A7 Bolt Pattern: 5×112 Wheel Fitment Guide by Generation

Introduction

The Audi A7 bolt pattern is 5×112 for the 4G8 and 4K8 generations. There is more to a wheel fitment than just the bolt pattern. Before proceeding with the selection of replacement or aftermarket wheels on an Audi A7, it is crucial to establish the correct A7 generation and to verify the full wheel specification.

Audi A7 Bolt Pattern by Generation

According to current fitting databases, all major generations of the Audi A7 have used a 5×112 bolt pattern. The A7 applications identified by Wheel-Size consist of the 4G8 from 2010-2015, 4G8 facelift from 2014-2018, 4K8 from 2018-2023, and lastly, the 4K8 facelift from 2023 onward in its current generation timeline.

This indicates that the change of generation from C7 to C8 does not alter the Audi A7 lug pattern. For wheel distributors and retailers, that uniformity simplifies the first part of the fitment identification process. Nonetheless, identifying the specific vehicle application is still essential.

Audi A7 5×112 Generation Chart

The 2014 model year has a special mention. Wheelsize.com lists the original 4G8 and the 4G8 Facelift for the year. The original 4G8 has production applications through 2014, whereas the facelifted 4G8 has production applications from 2014 onward.

Thus, just the model year is not enough for you to check the Audi A7 wheel fitment.. Chassis or generation is a better place to start, especially for a car built around a transition year.

Does the Audi A7 bolt pattern change by generation?

The most popular A7 generation of the Audi major use 5×112, making use of Wheel-Size’s generation level for the details 5×112 listed for a 4G8, 4G8 facelift, 4K8, and 4K8 facelift.

One thing to note, though, is that just because the PCD is consistent, that does not mean every wheel specification is identical. The diameters, widths, offsets, tire specifications, and other fitment parameters can be completely different between applications. And that is important, as all of those characteristics are taken into account when choosing a wheel for a particular A7.

What Changes Between A7 Generations if the Bolt Pattern Doesn’t?

5×112 PCD bolt pattern determines the mounting hole pattern of the wheel. But it does not fully describe wheel fitment. This was well demonstrated by the Audi A7 wheel fitment. Different factory wheel and tire combinations have been given in Wheel-Size for the same generation wheel size and width.

A 4G8 fitment included 255/45ZR18 & 265/35ZR20 with 4G8 8.5JΧ18 ET32 wheel 9.0JΧ20 ET37 tire and 9.0JΧ21 ET35 tire tyre with 275/30ZR21 wheel. These fitments are non-interchangeable in cases where the fitment has a 5×112 pattern only.

There are different fitments with 4K8 in a similar pattern. In A7 application of 2019, 8.0JΧ18 ET26, 8.0JΧ19 ET27, 8.5JΧ20ET30, and 5JΧ21 ET30 are the fitments.

From all this information, if you own an Audi A7 PCD can be your fitment guide, but it should be noted that this is only the starting point. It’s possible to have the same five-lug pattern but different width, offset, tire combination, and/or clearance profile.

Audi A7 Wheel Size Examples by Generation

Documented fitment data for an A7 model featured in different wheel diameters. The wheel diameter range includes 18inch alloy wheel, 19 inch alloy wheel, 20 inch alloy wheel and 21-inch alloy wheel applications. However, the combination is based on the generation, engine, trim, market, and vehicle design.

Thus, the Audi A7 wheel size is specification data instead of a choice between selecting larger and smaller wheels..

Other guides available on the internet do give a specific example for the A7/S7 4K80 for aftermarket fitment. An application specified 20x9ET25 front and 20×10.5ET35 rear wheels and 275/35-20 front and 295/30-20 rear tires is listed. Our guides and experts indicated that these are, in fact, the company’s recommended fitments and that the application clears RS7 calipers. These are the Kipardo or any other aftermarket fitment recommendations, which should not be interpreted as a universal Audi factory specification.

The simple point in practice is that wheel diameter alone does not determine compatibility. For instance, the 20-inch Audi aftermarket wheel application still must qualify by its complete specification rather than by diameter alone or by 5×112 PCD alone.

Audi A7 Center Bore and Wheel Fitment: What to Verify

Center bore is another value that needs to be verified once you have found out the Audi A7 bolt pattern. A 66.56 mm hub-centric center bore is specified for the A7/S7 4K8 in the Kipardo and other reputable fitment guides, along with a 5×112 bolt pattern and 60-degree conical hardware. This is a particular aftermarket application specification and not a standard value to assign to all A7 wheels.

For distributors and dealers, the right method to verify is by comparing the center bore on the wheel with the hub on the vehicle, and verifying the application data provided by the manufacturer. A wheel might have the right PCD, but it still needs to be checked before listing it as compatible.

KIPARDO’s present Hub Centric vs Lug Centric Wheels Explained article offers a broader explanation of hub-centric fitment, center bore, and hub rings than what needs to be checked for A7.

Can S7 or RS7 Wheels Fit an Audi A7?

In the fitment data available, the A7, S7, and RS7 have a 5×112 lug bolt pattern in common. But just because they have the same PCD lug pattern doesn’t mean any wheel can move between all three models. The correct wheel specification and vehicle setup will still determine compatibility.

Most importantly, they need to have enough brake clearance. Performance versions will often offer different brake packages, which will change the space behind the wheel spokes. This means that, with the correct PCD and hub bore, you might need a different offset or spoke profile of that wheel to clear the brake.

A useful example for this is provided by Kipardo, Fifteen52, and others. Their A7/S7 4K8 application suggests 20×9 ET25 and 20×10.5 ET35, with the note that it clears RS7 calipers. This means that caliper clearance can be dealt with via a specific wheel design and specification. Yet, it doesn’t follow that all Audi RS7 wheels will fit every A7.

The same goes for when you want to use Audi S7 wheels. You may be able to use S7 wheels on an A7. But you need to make sure that the exact wheel width, ET, spoke geometry, center bore, tire specification, caliper clearance, and bolts are the same or compatible.

Can Other 5×112 Audi Wheels Fit an A7?

A wheel from another Audi model can be a potential fitment for an A7, but 5×112 alone is not enough to confirm compatibility. The shared PCD establishes the mounting pattern. It does not establish whether the wheel’s physical dimensions and application requirements match the A7.

For distributors, the screening process should therefore go beyond searching for 5×112 Audi wheels. Center bore, wheel width, ET, brake clearance, tire compatibility, load rating, and hardware all need to be checked against the intended A7 application.

Depending on how the screening process is being approached, the 5×112 wheel from a different model of the Audi can definitely be checked (it is a potential fitment for an A7), but that alone isn’t enough to determine compatibility for two major reasons.

The fact that both vehicles have markings of 5×112 could be used to confirm that the two cars have similar PCD. However, that doesn’t mean anything other than that the mounting pattern is the same in both vehicles. Although the wheels are classified as 5ÂÂ×112, the physical size, dimensions, and the requirements of both vehicles being the same aren’t confirmed by this value.

This is especially significant for the Wheels for Audi store. You can’t call a wheel “A7 compatible” just because it can be seen in the 5×112 Product Search. The complete setup should satisfy the application.

For the wider range of products, checking the Audi aftermarket wheels in KIPARDO could be the next step if the technical fitment becomes successful.

A7 Wheel Fitment Checklist for Distributors and Retailers

To manage A7 wheel applications effectively for retailers and distributors, the most reliable approach would be to record both vehicle and wheel specifications together. The first step includes identification of the A7 chassis, such as 4G8 or 4K8, and then verification of the specific production and vehicle application.

After that, it should be checked for 5×112 PCD. The diameter and width of the wheel and ET should match the intended application. How should the center bore be matched, along with brake and spoke clearance? The chosen tire specification should also tally with the wheel and vehicle. Lastly, confirmation of mounting hardware and wheel load rating with manufacturer’s application data needs to be done.

A workflow that is much better than a simple “Audi A7 compatible“ label, which can cover different generations and wheel specifications of the identical version name, while aftermarket brakes can differ from one person to another in diameter, offset, spoke profile, and mounting requirements.

Therefore, the B2B inventory management takeaway will be to list your record A7 wheel inventory by generation and complete wheel specification, not by vehicle name alone. That way, your product compatibility is certainly more accurate, and you could reduce your risk of approving a shared 5×112 pattern as a whole fitment.

Cast, Flow-Formed and Forged Wheels

Wheel manufacturing method and market categorization represent two different concepts of wheel construction. Although Cast, flow-formed, and forged describe wheel manufacturing, the wheels can also be original equipment, replica, or aftermarket. Forged monoblock wheels are manufactured as a single-piece construction rather than built up of separate components.

Conclusion

Audi A7 bolt pattern remains 5×112 for the major generations. But verified wheel fitment provides more than just PCD. Make sure to verify generation, diameter, width, ET, centre bore, brake clearance, tyre, and mounting requirements before choosing a wheel.
