The 2020 Audi A7 Sportback blends modern grand touring character with the sleek fastback profile that has defined Audi’s larger four-door hatchback sedans in recent years. It is a refined, technology-forward luxury car, but tire choice still comes down to the exact wheel package on the car. This model uses radial tires in three sizes: 245/45R19, 255/40R20, and 255/35R21. Available choices center on blackwall performance-oriented radials from BFGoodrich and Nitto, with series differences that matter once the correct size is confirmed. For an A7 Sportback, the real priority is matching the tire to the installed wheel diameter before comparing brand, series, and road-use goals.
Which Tire Size Is Right for The 2020 Audi A7 Sportback
Three tire sizes apply to the 2020 Audi A7 Sportback, and the first step is confirming the wheel diameter currently on the car. Fitment varies by sub-model and wheel package across 19-inch, 20-inch, and 21-inch rims, so the real decision is not just tire brand but identifying the correct size before comparing the available radial options.
245/45R19 is a metric radial size in which 245 identifies the nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 19 is the rim diameter in inches. On the 2020 Audi A7 Sportback, this size suits cars equipped with 19-inch wheels and keeps the tire choice within a modern radial format. Available options include blackwall tires from BFGoodrich and Nitto across g-Force Comp 2 AS, Nitto NT555 G2, and g-Force Phenom T/A series. This size is the right place to start when your A7 Sportback is on its 19-inch wheel setup and you want to compare performance-oriented replacement choices.
255/40R20 is a metric radial size that uses a 255-millimeter nominal section width, a 40-series profile, and a 20-inch rim diameter. For the 2020 Audi A7 Sportback, this size belongs to cars fitted with 20-inch wheels and reflects a lower-profile radial package than the 19-inch option. The available product selection in this size centers on a blackwall BFGoodrich g-Force Phenom T/A, so the comparison is less about sidewall style and more about confirming the proper wheel setup. It is the size to evaluate when the car already wears 20-inch rims and the goal is staying with the correct modern fitment format.
255/35R21 is a metric radial size with a 255-millimeter nominal section width, a 35-series profile, and a 21-inch rim diameter. On the 2020 Audi A7 Sportback, this size applies only to configurations using 21-inch wheels, making wheel confirmation especially important before moving forward. The lower-profile format makes this size distinct from the 19-inch and 20-inch options even though the width class remains similar to the 255/40R20 setup. It should be considered only when the car is already equipped for 21-inch fitment and the wheel, clearance, and overall setup match that requirement.
Sub-model fitment for the 2020 Audi A7 Sportback depends on the exact trim and wheel package. Premium and Premium Plus share the same two tire-size paths, while Prestige adds a 21-inch option that makes wheel confirmation even more important.

2020 Audi A7 Sportback Premium
The 2020 Audi A7 Sportback Premium uses radial tire fitments tied to either a 19-inch or 20-inch wheel setup. Tire selection starts with confirming which wheel diameter is on the car, then narrowing the choice by brand and tire series within the correct size.
The 2020 Audi A7 Sportback Premium Plus follows the same fitment pattern as Premium, using radial tires on either 19-inch or 20-inch wheels. That makes size confirmation the key step before comparing the available blackwall replacement options in the proper metric radial size.
The 2020 Audi A7 Sportback Prestige can use 19-inch, 20-inch, or 21-inch radial tire fitments depending on the wheel package. Because this trim has the widest fitment spread, the safest approach is to verify the actual wheel diameter on the car before selecting a replacement tire.
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 2020 Audi A7 Sportback Tires for Sale
Available 2020 Audi A7 Sportback tire choices center on blackwall radial performance tires in 245/45R19 and 255/40R20. BFGoodrich and Nitto appear in the 19-inch fitment, while the 20-inch size is represented by the BFGoodrich g-Force Phenom T/A.
These FAQs focus on the tire sizes used on the 2020 Audi A7 Sportback, how fitment changes by trim and wheel diameter, and what to compare when choosing between the available radial replacement options.
Tire Size & Fitment
What tire size fits a 2020 Audi A7 Sportback?
The 2020 Audi A7 Sportback uses three tire sizes: 245/45R19, 255/40R20, and 255/35R21. All three are radial sizes, and the correct one depends on the wheel diameter and trim configuration on the car rather than a single universal fitment across every A7 Sportback.
The practical first step is checking the wheel that is actually installed, since a 19-inch tire cannot be mounted on a 20-inch or 21-inch rim. Premium and Premium Plus use 19-inch or 20-inch paths, while Prestige can also use a 21-inch setup, so the car’s exact wheel package matters before comparing replacement tires.
What size rim does a 2020 Audi A7 Sportback use?
A 2020 Audi A7 Sportback can use 19-inch, 20-inch, or 21-inch rims depending on trim and wheel package. The 245/45R19 tire matches a 19-inch rim, 255/40R20 matches a 20-inch rim, and 255/35R21 matches a 21-inch rim.
That rim diameter determines the tire size you can consider, so it should be verified before looking at brands or series. Looking only at the sidewall width or profile can lead to confusion, especially on a car like the A7 Sportback where more than one factory-size path exists across closely related sub-models.
Do all 2020 Audi A7 Sportback sub-models use the same tire size?
No, the 2020 Audi A7 Sportback sub-models do not all use one shared tire size. Premium and Premium Plus use 245/45R19 or 255/40R20, while Prestige can use 245/45R19, 255/40R20, or 255/35R21 depending on the wheel setup.
That means trim name alone is helpful, but the installed wheel diameter still needs to be confirmed on the car before ordering tires. Prestige is the clearest example, since it spans three fitment possibilities, and a replacement decision should always start with matching the tire to the actual rim size already in service.
Choosing the Right Tire
What should I consider when choosing a 245/45R19 tire for a 2020 Audi A7 Sportback?
For a 2020 Audi A7 Sportback using 245/45R19, the main considerations are staying with the correct size, confirming compatibility with the car’s 19-inch wheels, and comparing the available radial product lines. In this fitment, BFGoodrich and Nitto are both available, with blackwall choices in g-Force Comp 2 AS, Nitto NT555 G2, and g-Force Phenom T/A series.
Once size is settled, the decision shifts to how you use the car and which product specifications matter most to you. Rim-width suitability, load figures where stated, and the overall character of the tire series are all worth comparing, especially on a luxury sportback that may see a mix of touring, daily road use, and more spirited driving.
What sidewall styles are available for 2020 Audi A7 Sportback tires?
The available replacement tires for the listed 2020 Audi A7 Sportback fitments use a blackwall sidewall style. That applies to the 245/45R19 and 255/40R20 product options, keeping the appearance modern and in line with the car’s contemporary sport-luxury presentation.
Since sidewall treatment does not vary within the available products here, the bigger comparison points become tire size, brand, and series. A7 Sportback owners choosing between 19-inch and 20-inch fitments should treat sidewall style as settled and focus instead on matching the correct wheel diameter and selecting the radial tire line that suits the car’s intended use.
What brands offer tires for the 2020 Audi A7 Sportback?
BFGoodrich and Nitto offer replacement tires for the 2020 Audi A7 Sportback within the available fitments. BFGoodrich appears in both 245/45R19 and 255/40R20, while Nitto appears in the 245/45R19 size with the NT555 G2.
Brand should be compared alongside the exact size and tire series rather than treated as the only decision point. On this Audi, fitment accuracy comes first, then it makes sense to compare the available blackwall radial options by series character, rim-width suitability where stated, and how the car will actually be driven.
Restoration & Appearance
Does correct tire fitment matter for a 2020 Audi A7 Sportback restoration?
Yes, correct tire fitment still matters on a 2020 Audi A7 Sportback even though it is a modern vehicle rather than a vintage restoration subject. The car uses three distinct metric radial sizes tied to different wheel diameters, so preserving the proper size relationship is important to the way the car sits and presents visually.
Appearance on a contemporary Audi is shaped more by wheel-and-tire proportion than by whitewalls or vintage sidewall treatments, since the available options here are blackwall radials. A restoration-minded owner should confirm the intended trim and wheel package, then select a tire that keeps the car’s original-style wheel diameter and overall presentation intact.
How does tire construction affect the appearance of a restored 2020 Audi A7 Sportback?
Tire construction has less visual variation on a 2020 Audi A7 Sportback than it does on collector cars because the primary fitments are all modern radial sizes. The visible appearance is driven more by the correct 19-inch, 20-inch, or 21-inch wheel-and-tire combination and by the clean blackwall sidewall style used in the available products.
For an owner aiming to return the car to a proper period presentation, staying with the correct metric radial size matters more than searching for alternate construction types. The most noticeable mistake would be choosing a tire that does not match the installed wheel diameter or intended trim-level wheel package, since that changes both stance and visual balance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Audi A7 Sportback?
Yes, modifications can affect tire fitment on a 2020 Audi A7 Sportback. Wheel changes, altered offsets, suspension lowering, and other aftermarket changes can influence how 245/45R19, 255/40R20, or 255/35R21 tires sit within the fenders and how much clearance remains during steering and suspension movement.
A car that still uses one of the original-size tire codes may still need closer checking if the wheel width or overall setup has changed. It is wise to verify wheel diameter, width, and clearance at full lock and under compression so the replacement tire matches the actual vehicle configuration rather than only the original trim fitment path.
What should I inspect before driving a 2020 Audi A7 Sportback on new tires?
Before driving a 2020 Audi A7 Sportback on new tires, inspect the wheel diameter and tire size match, confirm that each tire is seated properly, and check inflation pressure. It is also smart to look over the wheels themselves for damage and make sure the tires have adequate clearance to surrounding suspension and body components.
After the first short drive, recheck pressure and look for any signs of rubbing, vibration, or uneven contact. A vehicle like the A7 Sportback places a premium on smoothness and stability, so any issue with mounting, wheel condition, or clearance should be addressed early rather than assuming the correct size code alone guarantees the whole setup is right.
How often should tires on a 2020 Audi A7 Sportback be inspected?
Tires on a 2020 Audi A7 Sportback should be inspected regularly, not just when tread appears low. Frequent checks for air loss, uneven wear, cuts, bulges, and sidewall damage are worthwhile, especially on low-profile sizes such as 255/40R20 and 255/35R21 where wheel and road impacts can be more noticeable.
Routine inspection is particularly useful if the car sees seasonal storage, long highway trips, or rough pavement. Tire pressure should be monitored consistently, and any change in ride quality, steering feel, or visible wear pattern deserves attention, since catching a problem early is often the best way to preserve both tire life and road manners.
