The 2023 Audi A7 Sportback blends coupe-like roofline styling with the everyday utility and long-distance composure expected from a modern Audi luxury performance hatchback. Its clean, low stance and substantial wheel openings make tire fitment especially important, because the right size affects both appearance and how the car sits on the road. This model uses radial tires in two primary sizes, 255/40R20 and 255/35R21, depending on trim and wheel setup. That makes the real decision less about vintage-style construction choices and more about confirming the exact sub-model and wheel diameter before comparing available tires. For a contemporary A7, correct sizing and wheel match come first.
Which Tire Size Is Right for The 2023 Audi A7 Sportback
The 2023 Audi A7 Sportback uses two primary tire sizes, and the correct one depends on the exact trim and wheel diameter. Both are radial metric sizes, but one fits a 20-inch wheel and the other fits a 21-inch wheel, so confirming the actual wheel setup is the first step before choosing a tire.
255/40R20 is a modern metric radial size in which 255 is the nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 20 is the wheel diameter in inches. On the 2023 Audi A7 Sportback, this size is one of the primary fitments and is used on 20-inch wheels. Available choices in this size include BFGoodrich in the g-Force Phenom T/A series with a Blackwall sidewall treatment. This size is the one to evaluate when the car is equipped with the 20-inch wheel package and you want to compare current product specifications within that fitment.
255/35R21 follows the same modern metric radial format, with a 255-millimeter nominal section width, a 35-series profile, radial construction, and a 21-inch rim diameter. On the 2023 Audi A7 Sportback, this size applies to configurations equipped with 21-inch wheels rather than the 20-inch setup. The lower profile and larger wheel diameter make wheel confirmation especially important before selecting a replacement tire. This is the size to focus on when the vehicle has the larger factory-style wheel package or a matching 21-inch setup already installed.
Tire fitment on the 2023 Audi A7 Sportback varies by sub-model, so trim level matters before any tire choice is made. Premium and Premium Plus stay with one 20-inch fitment, while Prestige may use either of the two primary sizes depending on wheel setup.

2023 Audi A7 Sportback Premium
The 2023 Audi A7 Sportback Premium uses a single radial tire fitment built around the 20-inch wheel setup. That makes tire selection more straightforward, with the main task being to confirm the existing wheel size and then compare available tires within the correct metric radial size.
The 2023 Audi A7 Sportback Premium Plus also uses one radial tire fitment on a 20-inch rim. For this trim, the focus is on matching the existing wheel diameter and then choosing among available tires based on construction, series, and product specifications in the correct size.
The 2023 Audi A7 Sportback Prestige can use either of the two primary radial sizes, depending on whether the car carries the 20-inch or 21-inch wheel package. Tire selection starts with confirming the actual wheel diameter on the vehicle, since the two sizes are not interchangeable across different rim diameters.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 2023 Audi A7 Sportback Tires for Sale
Current product choices for the 2023 Audi A7 Sportback are centered on the 255/40R20 size, with BFGoodrich offering a radial Blackwall option in the g-Force Phenom T/A series. That makes size confirmation the key first step before comparing product-level specifications.
Common questions for the 2023 Audi A7 Sportback usually come down to the correct tire size by trim, 20-inch versus 21-inch wheel fitment, and what to inspect before replacing tires on a modern luxury performance hatchback.
Tire Size & Fitment
What tire size fits a 2023 Audi A7 Sportback?
The 2023 Audi A7 Sportback uses two primary tire sizes: 255/40R20 and 255/35R21. Premium and Premium Plus use 255/40R20, while Prestige may use either 255/40R20 or 255/35R21 depending on the wheel package installed on the car.
The key is to match the tire size to the actual wheel diameter on the vehicle. A 20-inch tire cannot be used on a 21-inch wheel, and a 21-inch tire cannot be mounted on a 20-inch wheel. Before ordering replacements, confirm the trim level, inspect the sidewall of the current tires, and verify that the car still has its intended wheel setup.
What size rim does a 2023 Audi A7 Sportback use?
The 2023 Audi A7 Sportback uses either a 20-inch or 21-inch rim, depending on trim and wheel configuration. The 255/40R20 tire is paired with a 20-inch rim, while the 255/35R21 tire is paired with a 21-inch rim.
Rim diameter is the first fitment detail to confirm because it determines which tire size can even be considered. After that, wheel width and any non-original wheel changes should also be checked, especially on Prestige models that may have either setup. Looking at the markings on the wheel or current tire sidewall is the fastest way to confirm what is installed.
Do all 2023 Audi A7 Sportback sub-models use the same tire size?
No, not all 2023 Audi A7 Sportback sub-models use the same tire size. Premium and Premium Plus use 255/40R20, while Prestige can use either 255/40R20 or 255/35R21 depending on the wheel package fitted to that specific car.
That means trim level alone is helpful, but it is not always enough on a Prestige model. A quick inspection of the current tire sidewall or wheel diameter prevents ordering the wrong size. This matters even more if the car has had wheel changes, because a different wheel package can alter which tire size belongs on the vehicle now.
Choosing the Right Tire
What should I consider when choosing a 255/40R20 tire for a 2023 Audi A7 Sportback?
Start by confirming that 255/40R20 is the size actually installed on the car and that it matches a 20-inch wheel. For the 2023 Audi A7 Sportback, that size is used on Premium and Premium Plus models and can also appear on Prestige depending on wheel configuration.
Once size is confirmed, compare construction, load specification, rim-width compatibility, tire series, and sidewall style. One available option in this size is a BFGoodrich g-Force Phenom T/A Blackwall radial, which fits wheels in the stated 8.5 to 10 inch range. Checking those details helps narrow the selection to a tire that suits both the wheel and the car's intended road use.
What sidewall styles are available for 2023 Audi A7 Sportback tires?
Available product coverage for the 2023 Audi A7 Sportback currently includes a Blackwall sidewall style in the 255/40R20 fitment. That gives the car a clean, contemporary presentation that suits the A7 Sportback's modern body design and large-diameter wheel appearance.
Sidewall style is mainly an appearance decision once the correct size and wheel match are confirmed. On a modern Audi, most buyers will focus first on proper size, load capability, and wheel compatibility, then choose the sidewall treatment that best matches the car's look. It is still important to keep sidewall style separate from fitment, since appearance does not change the required tire size.
What brands offer tires for the 2023 Audi A7 Sportback?
Current product coverage for the 2023 Audi A7 Sportback includes BFGoodrich in the 255/40R20 size. The available tire is from the g-Force Phenom T/A series and uses radial construction with a Blackwall sidewall.
Brand is only one part of the selection process on this car. The tire still needs to match the installed wheel diameter, the intended size for the trim, and the wheel's width range. Comparing those details first keeps the choice focused on fitment and specification rather than relying on brand name alone to make the decision.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Audi A7 Sportback?
Yes, modifications can affect tire fitment on a 2023 Audi A7 Sportback. Aftermarket wheels, suspension changes, lowering, spacers, or body modifications can change the clearance relationship between the tire, fender, suspension components, and steering system even when the tire size appears close to stock.
Any car that no longer has its original wheel and suspension setup should be checked carefully before replacement tires are chosen. Wheel diameter, wheel width, and offset all matter, especially when comparing 20-inch and 21-inch fitments. Turning the steering fully, inspecting fender clearance, and confirming the exact size currently on the vehicle can prevent expensive fitment mistakes.
What should I inspect before driving a 2023 Audi A7 Sportback on new tires?
Before driving a 2023 Audi A7 Sportback on new tires, inspect inflation pressure, wheel condition, lug torque, and the basic condition of the suspension and alignment-related wear points. It also helps to make sure the installed tire size matches the wheel diameter and the trim's intended fitment.
A short road test should include listening for rubbing, checking steering feel, and verifying that the tires clear the inner liners and suspension through normal turning. After a few miles, recheck pressure and look for any uneven contact or unusual marks on the sidewall. Those simple checks help confirm that the tire and wheel package is working correctly on the car.
How often should tires on a 2023 Audi A7 Sportback be inspected?
Tires on a 2023 Audi A7 Sportback should be inspected regularly, not just when replacement time arrives. A quick visual check for uneven wear, cuts, punctures, bulges, embedded debris, and pressure loss is smart before longer drives, and a closer inspection should be part of normal routine maintenance.
Performance-oriented luxury cars can be more sensitive to alignment, wheel damage, and low-profile tire issues, especially on larger wheel packages. Looking over the inside and outside shoulders of the tread can reveal problems early. Keeping an eye on sidewall condition and pressure helps preserve ride quality, handling consistency, and tire life while reducing the chance of an avoidable road issue.
