The 2019 Audi A7 Sportback blends a sleek fastback profile with the refined, technology-focused character that defines Audi’s modern luxury performance cars. It sits in a space where appearance, ride quality, and confident road manners all matter, so tire choice has a noticeable effect on how the car presents and drives. This model uses radial tire fitments in 245/45R19, 255/40R20, and, on certain Prestige configurations, 255/35R21. Available choices center on modern blackwall performance-oriented tires from BFGoodrich and Nitto in select sizes. The key is matching the exact wheel diameter and sub-model setup before comparing series, load-related specs, and overall driving intent.
Which Tire Size Is Right for The 2019 Audi A7 Sportback
The 2019 Audi A7 Sportback uses three primary tire sizes, and the right one depends first on the exact sub-model and wheel diameter on the car. All three are radial metric sizes, but they span 19-inch, 20-inch, and 21-inch rims, so confirming the actual wheel setup matters before comparing tire series, load-related specifications, or replacement style within the correct size.
245/45R19 is a metric radial size in which 245 indicates nominal section width in millimeters, 45 is the aspect ratio, R designates radial construction, and 19 is the rim diameter in inches. On the 2019 Audi A7 Sportback, this size supports a modern road-going setup with a balance of sidewall height and wheel diameter appropriate to the car’s luxury-sport character. Available choices in this size include BFGoodrich and Nitto blackwall tires across the g-Force Comp 2 AS, Nitto NT555 G2, and g-Force Phenom T/A series. It is the size to evaluate when the car is equipped with 19-inch wheels and the goal is to stay with the original wheel diameter.
255/40R20 is a metric radial size with a 255-millimeter nominal section width, a 40-series profile, and a 20-inch rim diameter. For the 2019 Audi A7 Sportback, it represents a larger-wheel fitment than the 19-inch option while remaining within the model’s primary radial sizing range. The currently available product choice in this size is a BFGoodrich g-Force Phenom T/A blackwall tire, giving this fitment a more focused product selection than 245/45R19. This is the size to consider when the car wears 20-inch wheels and the priority is matching that wheel diameter before comparing other tire details.
255/35R21 is a metric radial size where 255 identifies nominal section width in millimeters, 35 is the aspect ratio, and 21 is the wheel diameter in inches. On the 2019 Audi A7 Sportback, this size appears on certain Prestige configurations and reflects the largest rim-diameter fitment used within this model range. Its shorter sidewall changes the fitment context compared with the 19-inch and 20-inch options, so wheel confirmation becomes especially important before any replacement decision. This is the size to follow only when the car already carries the 21-inch setup associated with that specific configuration.
Sub-model fitment is not identical across the 2019 Audi A7 Sportback range, so checking the exact trim matters before choosing a tire. Premium and Premium Plus use the same two primary sizes, while Prestige adds a 21-inch fitment that changes the wheel-diameter decision.

2019 Audi A7 Sportback Premium
The 2019 Audi A7 Sportback Premium uses radial tire fitments in 245/45R19 and 255/40R20. Tire selection starts with confirming whether the car has 19-inch or 20-inch wheels, then comparing the available blackwall product choices within that exact size.
The 2019 Audi A7 Sportback Premium Plus shares the same radial tire fitment pattern as Premium, with 245/45R19 and 255/40R20 options. That makes wheel diameter the first checkpoint, followed by the available tire series and rim-width compatibility in the matching size.
The 2019 Audi A7 Sportback Prestige can use 245/45R19, 255/40R20, or 255/35R21 depending on the wheel setup. On this trim, confirming the actual rim diameter on the vehicle is essential before evaluating replacement tires or comparing sidewall profile differences.
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.

Tire Size & Fitment
What tire size fits a 2019 Audi A7 Sportback?
The 2019 Audi A7 Sportback uses three primary tire sizes: 245/45R19, 255/40R20, and 255/35R21. Premium and Premium Plus use 245/45R19 or 255/40R20, while Prestige adds a 255/35R21 fitment alongside the 19-inch and 20-inch options.
The main step is confirming the exact wheel diameter already on the car, since these sizes are tied to different rims. A replacement tire should match the wheel size first, then be checked for rim-width suitability, load-related specifications, and clearance if the car has been modified from its original setup.
What size rim does a 2019 Audi A7 Sportback use?
A 2019 Audi A7 Sportback can use 19-inch, 20-inch, or 21-inch rims depending on the tire size and trim configuration. The 245/45R19 tire uses a 19-inch rim, 255/40R20 uses a 20-inch rim, and 255/35R21 uses a 21-inch rim.
Rim diameter should be confirmed before any tire purchase because a metric size with a similar section width does not cross over to a different wheel diameter. Looking at the current tire sidewall, wheel markings, or the vehicle’s installed setup is the safest way to avoid selecting the wrong fitment.
Do all 2019 Audi A7 Sportback sub-models use the same tire size?
No, not all 2019 Audi A7 Sportback sub-models use the same tire-size range. Premium and Premium Plus use 245/45R19 and 255/40R20, while Prestige can use those same sizes plus 255/35R21.
That means trim alone is helpful, but the actual wheel package on the car still needs to be checked before choosing a tire. On Prestige in particular, the extra 21-inch option makes wheel confirmation especially important, since the correct replacement path changes with rim diameter and sidewall profile.
Choosing the Right Tire
What should I consider when choosing a 245/45R19 tire for a 2019 Audi A7 Sportback?
A 245/45R19 tire for the 2019 Audi A7 Sportback should first match the car’s 19-inch wheel setup, then be compared by tire series, brand, and rim-width compatibility. In this size, available choices include BFGoodrich and Nitto blackwall radial tires across several performance-oriented series.
Selection usually comes down to how the car is used and which product details matter most to the owner. Comparing rim-width ranges, weight, and any stated load capacity can help narrow the choice, especially if the car is driven regularly rather than used only for occasional fair-weather miles.
What sidewall styles are available for 2019 Audi A7 Sportback tires?
The available products for the 2019 Audi A7 Sportback in the covered sizes use a blackwall sidewall style. That applies to the listed 245/45R19 and 255/40R20 tire options from BFGoodrich and Nitto.
For this vehicle, sidewall appearance is straightforward rather than decorative, so the more meaningful differences are tire series, brand, and size-specific specifications. Once the correct size is confirmed, the comparison shifts from sidewall treatment to how each radial option suits the car’s intended driving use and wheel setup.
What brands offer tires for the 2019 Audi A7 Sportback?
BFGoodrich and Nitto offer tires for the 2019 Audi A7 Sportback within the currently available product range. BFGoodrich appears in both 245/45R19 and 255/40R20, while Nitto appears in 245/45R19.
Brand is only one part of the decision, because availability also changes by tire size. After matching the correct wheel diameter and tire size, it helps to compare the tire series in that size and review practical details such as rim-width compatibility, load-related specifications, and the type of driving the car will actually see.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Audi A7 Sportback?
Yes, modifications can affect tire fitment on a 2019 Audi A7 Sportback. Aftermarket wheels, changes in wheel width or offset, suspension lowering, and body or fender alterations can all influence whether the original tire size still has proper clearance.
Even when the tire size matches one of the standard fitments, the installed wheel and suspension setup may change how that tire sits in the car. It is wise to check steering clearance, inner clearance, and fender room before replacing tires, especially on cars that no longer retain their original wheel specifications.
What should I inspect before driving a 2019 Audi A7 Sportback on new tires?
Before driving a 2019 Audi A7 Sportback on new tires, inspect wheel condition, confirm the tire size matches the rim diameter, and verify that inflation pressure is set correctly for the application. It also helps to look for any visible interference at the fenders, suspension, or steering components.
A short initial road check is useful after installation to catch vibration, rubbing, or other signs that the setup needs attention. Tire age on any existing spare, uneven wear patterns, and alignment condition are also worth reviewing, since fresh tires can reveal underlying chassis or wheel issues more clearly.
How often should tires on a 2019 Audi A7 Sportback be inspected?
Tires on a 2019 Audi A7 Sportback should be inspected regularly, not only when they appear worn. A routine check for tread condition, cuts, bulges, sidewall damage, and pressure loss helps catch problems early, particularly on a car that may see seasonal or irregular use.
Inspection should also follow any pothole impact, curb contact, or wheel change, since those events can affect both the tire and the rim. Looking over the tires before longer drives is especially worthwhile, because condition, pressure, and even wear matter just as much as choosing the correct size in the first place.
