Audi A7 Sportback Tires

Audi A7 Sportback fitments in this range use three tire sizes. Size 245/45R19 applies to 2019 and 2020 models and uses a 19-inch rim. Size 255/40R20 applies from 2019 through 2025 and uses a 20-inch rim. Size 255/35R21 also applies from 2019 through 2025 and uses a 21-inch rim.

The practical point is that year alone does not always identify the correct tire on an Audi A7 Sportback. A 2019 or 2020 car can fall into more than one wheel package, so the safest approach is to read the existing tire sidewall and confirm the wheel diameter on the car before matching a replacement size.

On an Audi A7 Sportback, 245/45R19 is a modern metric radial size code. The 245 is the nominal section width in millimeters, 45 is the aspect ratio, meaning the sidewall height is 45 percent of the section width, R means radial construction, and 19 is the rim diameter in inches. In this fitment group, that size belongs to 2019 and 2020 applications with 19-inch wheels.

Understanding the code helps you avoid the most common mistake, which is matching the tread width but missing the wheel diameter or profile. A 245/45R19 cannot substitute for a 255/40R20 or 255/35R21 without changing the wheel itself, and those lower-profile sizes also alter the tire’s overall proportions and fitment relationship to the car.

The 2019 Audi A7 Sportback shows three listed tire sizes because that model year appears with more than one wheel package. The sizes are 245/45R19, 255/40R20, and 255/35R21, and they correspond to 19-inch, 20-inch, and 21-inch rims rather than one interchangeable setup. The same pattern continues in 2020, while later years in this group drop the 19-inch listing.

That means the correct replacement tire depends on how your individual Audi A7 Sportback was equipped, not simply on the badge or model year. Check the sidewall of the tire currently on the car, compare front and rear if needed, and verify the wheel diameter before narrowing your selection to avoid choosing a tire for the wrong wheel package.

Audi A7 Sportback fitments in this group use three rim diameters: 19 inches, 20 inches, and 21 inches. The 19-inch fitment appears on 2019 and 2020 models with size 245/45R19, while 20-inch and 21-inch fitments appear from 2019 through 2025 with sizes 255/40R20 and 255/35R21. The wheel diameter is part of the tire code on these metric radial sizes.

Because multiple rim diameters are present in the same early model years, the wheel itself is the first thing to verify on an Audi A7 Sportback. Once the wheel diameter is confirmed, the correct tire size usually becomes straightforward, and you can then compare the available product choices within that exact size rather than across the full model range.

A 2020 Audi A7 Sportback can use 245/45R19, 255/40R20, or 255/35R21, so the correct size is tied to the wheel package on the specific car. Start by reading the full size code on the existing tire sidewall and confirming that it matches the wheel diameter actually fitted. In this model group, the rim diameter is 19, 20, or 21 inches depending on the setup.

If the car has changed hands or has had wheels replaced, do not assume the current setup matches original delivery configuration. Comparing the sidewall size, measuring the wheel if needed, and checking vehicle records together will give you a much more reliable answer than relying on year alone for an Audi A7 Sportback.

The available Audi A7 Sportback products in this fitment group are blackwall tires. The listed 19-inch and 20-inch products all use blackwall sidewalls, which suits the modern performance-luxury character of the A7 Sportback and matches the visual style most buyers expect on contemporary sport sedan and sportback wheel packages.

That means your decision here is less about sidewall appearance and more about selecting the correct size, wheel diameter, and product line. Once those are settled, blackwall presentation keeps the look clean and contemporary, especially on larger-diameter factory-style wheels where the tire sidewall is already relatively short and visually understated.

The listed Audi A7 Sportback tire options in this fitment group come from BFGoodrich and Nitto. BFGoodrich appears in both the 19-inch and 20-inch offerings, while Nitto appears in the 19-inch size. The available series include g-Force COMP-2 A/S, g-Force Phenom T/A, and Nitto NT555 G2.

Brand choice matters after size is confirmed, not before. On an Audi A7 Sportback, first narrow the selection to the correct wheel diameter and size code, then compare the available brand and series options within that fitment so you are evaluating products that actually belong on the car rather than crossing between incompatible wheel packages.

The listed Audi A7 Sportback products include BFGoodrich g-Force COMP-2 A/S, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. All are radial blackwall products, but they represent different product families within modern performance tire design. In this fitment group, g-Force Phenom T/A appears in both 19-inch and 20-inch sizes, while the other two series appear in the 19-inch size.

The practical takeaway is to compare series only within the exact size your Audi A7 Sportback requires. If your car uses 245/45R19, you have more than one series to consider, while the 255/40R20 listing is narrower. Matching the correct dimensions first keeps the comparison meaningful and avoids judging one series against another in a size your car does not use.

An Audi A7 Sportback stored on its tires should be kept in a cool, dry, dark environment away from direct sunlight, electric motors, ozone sources, and large temperature swings. Clean tires and wheels before storage, set inflation to an appropriate maintained level, and avoid leaving the car parked for long periods on wet concrete or contaminated surfaces that can accelerate rubber deterioration.

For longer storage, moving the Audi A7 Sportback slightly from time to time can help reduce flat spotting on low-profile radial tires. If the car will sit for an extended season, many collectors prefer using tire cradles or supporting the car in a way that reduces prolonged point loading while still keeping the suspension in a reasonable state.

Tires on an Audi A7 Sportback should be inspected regularly even if the car is driven only occasionally. A visual check before each drive is wise, and a more thorough inspection at least monthly should include pressure, tread wear pattern, sidewall condition, valve stems, and any signs of impact damage or irregular wear. Modern low-profile tires can show damage from potholes or curb contact that is easy to miss at a glance.

The benefit of frequent inspection is that it catches issues before they affect ride quality, handling, or wheel protection. On an Audi A7 Sportback with 20-inch or 21-inch wheels, sidewall height is relatively short, so proper pressure and early detection of bruises, cuts, or bulges are especially important for preserving both the tire and the wheel.

An Audi A7 Sportback tire can need replacement well before the tread looks worn out. Age, cracking, hardening of the rubber, repeated impact damage, bulges, persistent vibration, or uneven wear can all justify replacement even when tread depth still appears usable. Collector-owned or low-mileage cars are especially prone to age-related tire deterioration because time and environment can matter as much as miles.

That means the decision should not rest on tread alone. If an Audi A7 Sportback spends much of its life parked, periodic professional evaluation is a smart habit, especially before highway use or seasonal reactivation. Replacing aged tires proactively often restores the precision and ride quality that a modern grand touring chassis is meant to deliver.

The listed Audi A7 Sportback tires are modern radial products intended for public-road use when they are installed in the correct size on the correct wheel diameter and are maintained properly. Safety depends on more than the size code, though. Tire age, inflation, load condition, alignment, and the overall mechanical condition of the car all affect how safely the Audi A7 Sportback will drive.

The important step is to treat fitment and condition as a system. A fresh, correctly sized tire on an Audi A7 Sportback can still perform poorly if pressures are wrong or the alignment is out, while an incorrect size can create clearance or handling issues even if the tire itself is otherwise sound. Verify all of those basics before regular road use.

Before driving an Audi A7 Sportback, check tire pressure, sidewall condition, tread condition, and any visible cuts, punctures, or bulges. Confirm that all four tires match the intended fitment for the wheel package and that no wheel has obvious damage. A quick look at valve stems and a glance for irregular wear can also reveal problems before they become a road issue.

That routine matters even more on cars with lower-profile 20-inch or 21-inch tires, because shorter sidewalls leave less visual cushion and can hide impact-related problems until they worsen. Building a consistent pre-drive check into ownership helps the Audi A7 Sportback deliver the composed highway manners and precise steering response its chassis is designed to provide.

The appropriate speed for an Audi A7 Sportback depends on using the exact tire size fitted to the car, maintaining proper condition and inflation, and driving within the tire’s service capabilities and the vehicle’s overall condition. Even on a modern performance-luxury platform, road speed should reflect the state of the tires, the condition of the suspension and brakes, and the environment in which the car is being driven.

For practical ownership, that means avoiding the temptation to judge by appearance alone. If an Audi A7 Sportback has older tires, has been in storage, or shows any vibration or unusual wear, resolve those issues before sustained high-speed driving. A careful approach preserves both safety and the refined touring character that makes the A7 Sportback appealing in the first place.
