The 2025 Audi A6 Sportback e-tron brings Audi’s long-running A6 name into the modern EV era, blending sleek fastback styling with the quiet, substantial road manners buyers expect from an upscale sport sedan. Tire selection on this model is more involved than choosing a single size, because fitment varies by front and rear position and by package. The A6 Sportback e-tron uses radial tires in staggered 20-inch and 19-inch combinations, including 235/45R20 and 265/40R20 or 225/55R19 and 245/50R19. That makes wheel diameter, axle position, and package confirmation especially important before comparing available tire lines. Owners replacing tires should focus first on matching the exact front or rear fitment already on the car.
Which Tire Size Is Right for The 2025 Audi A6 Sportback e-tron
The 2025 Audi A6 Sportback e-tron uses four primary tire sizes across two staggered setups, and the correct choice depends on both trim package and whether the tire is for the front or rear axle. Before selecting a tire, confirm the exact sub-model and wheel diameter, since this car uses both 19-inch and 20-inch rim fitments rather than one universal size.
245/50R19 is a metric radial size in which 245 denotes nominal section width in millimeters, 50 is the aspect ratio, and 19 is the wheel diameter in inches. It is the rear fitment for the 19-inch Ultra Package setup on the 2025 Audi A6 Sportback e-tron, so it belongs to a staggered pairing rather than a same-size front and rear arrangement. Available choices in this size center on BFGoodrich products in blackwall form, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. Selection comes down to matching the 19-inch rear position and comparing the tire series and rim-width specifications that suit your wheel.
Sub-model fitment on the 2025 Audi A6 Sportback e-tron is position-specific and package-sensitive rather than uniform across the lineup. Checking the exact trim and whether the tire is for the front or rear axle matters first, because this car uses both 19-inch and 20-inch staggered combinations.

2025 Audi A6 Sportback e-tron Premium Front
The Premium Front fitment uses the 235/45R20 radial size as part of the 20-inch staggered setup. Tire selection here starts with confirming the front axle and retaining the proper match to the wider rear tire already used on this configuration.
The Premium Plus Front uses the same 235/45R20 radial fitment found on other 20-inch front applications in this model range. That keeps the decision focused on front-position replacement and wheel confirmation rather than sorting through multiple front tire sizes on the same trim.
The Premium Plus Rear uses 265/40R20, making it the rear half of the 20-inch staggered arrangement. Tire choice should stay tied to rear-axle replacement and the existing wheel setup, especially if the car has ever been fitted with aftermarket wheels.
The Premium Rear fitment uses the 265/40R20 radial size on a 20-inch wheel. That means the correct replacement decision is driven by rear position and staggered fitment, not simply by model year and trim name alone.
2025 Audi A6 Sportback e-tron Premium w/Ultra Pkg. Front
The Premium w/Ultra Pkg. Front uses 225/55R19 as the front tire in the 19-inch package. Owners should confirm that the car is still on the Ultra Package wheel setup before replacing tires, since this front size does not overlap with the 20-inch versions.
2025 Audi A6 Sportback e-tron Premium w/Ultra Pkg. Rear
The Premium w/Ultra Pkg. Rear uses 245/50R19, which completes the 19-inch staggered arrangement. That makes tire selection a matter of matching the rear position and comparing the available 19-inch rear tire options that suit the installed wheel width.
The Prestige Front fitment uses 235/45R20 on the front axle. Buyers replacing this tire should keep the front-specific role in mind and verify that the vehicle remains on its 20-inch staggered wheel package.
The Prestige Rear uses 265/40R20 as the rear tire size. That places the focus on preserving the correct rear fitment within the 20-inch staggered setup and checking wheel dimensions before moving to any alternate tire line.
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.

The most common questions for the 2025 Audi A6 Sportback e-tron center on staggered tire sizing, front-versus-rear fitment, 19-inch versus 20-inch wheels, and how to compare available tire options without upsetting the car’s intended setup.
Tire Size & Fitment
What tire size fits a 2025 Audi A6 Sportback e-tron?
The 2025 Audi A6 Sportback e-tron uses four primary radial tire sizes: 235/45R20, 265/40R20, 225/55R19, and 245/50R19. These sizes are not used interchangeably across the whole vehicle. They belong to staggered front-and-rear setups, with certain trims using 20-inch front and rear sizes and the Ultra Package using a different 19-inch front and rear combination.
The practical first step is identifying the exact trim and whether the tire being replaced is on the front or rear axle. Wheel diameter matters just as much, because the car uses both 19-inch and 20-inch fitments. Any car that has had wheels changed should be checked carefully before replacement so the new tire matches the actual wheel and position on the vehicle.
What size rim does a 2025 Audi A6 Sportback e-tron use?
The 2025 Audi A6 Sportback e-tron uses two rim diameters: 19 inches and 20 inches. The 235/45R20 and 265/40R20 sizes mount on 20-inch wheels, while the 225/55R19 and 245/50R19 sizes mount on 19-inch wheels. Rim diameter is tied directly to the tire size and cannot be mixed casually between these two setups.
Confirming the wheel diameter on the car is essential before comparing any tire choices. A correct front or rear size still will not work if it is paired with the wrong rim diameter. On a vehicle with staggered fitment, it is also smart to verify both axles individually rather than assuming the front and rear wheels match.
Why does the 2025 Audi A6 Sportback e-tron have more than one tire size?
The 2025 Audi A6 Sportback e-tron has more than one tire size because it uses staggered front-and-rear fitment, and some versions use a 20-inch package while the Ultra Package uses a 19-inch package. That creates separate front and rear tire sizes within each wheel package instead of one universal size for every corner.
This matters because replacement should follow the actual axle position and wheel package already on the car. Choosing by model name alone can lead to the wrong tire, especially when front and rear sizes differ. Matching the exact setup helps preserve the intended balance of the package and avoids problems with wheel compatibility or clearance.
Choosing the Right Tire
What should I consider when choosing a 245/50R19 tire for a 2025 Audi A6 Sportback e-tron?
A 245/50R19 tire for the 2025 Audi A6 Sportback e-tron should first match the correct rear application used on the Ultra Package setup. Within that size, available BFGoodrich choices differ by tire series, rim-width specification, weight, and related product characteristics. All are radial blackwall tires, so the comparison is mainly about selecting the series that best suits the wheel and intended use.
Rim-width compatibility is worth checking closely, since approved ranges vary slightly among the available 245/50R19 options. It also helps to confirm that the car still has its original 19-inch rear wheel setup and has not been altered. Once the fitment is confirmed, comparing the tire series becomes more meaningful than simply choosing by brand name alone.
What sidewall styles are available for 2025 Audi A6 Sportback e-tron tires?
Among the available products tied to this fitment, the visible sidewall style is blackwall. That applies to the current 245/50R19 offerings for the 2025 Audi A6 Sportback e-tron, which keeps the appearance straightforward and contemporary rather than introducing whitewall, redline, or other specialty sidewall presentations.
For this car, sidewall selection is less about vintage appearance and more about keeping the tire visually in step with a modern sport-luxury EV. Once the correct rear size and wheel are confirmed, the remaining comparison shifts toward tire series and wheel-width suitability. Buyers focused on overall appearance should also keep front and rear tire presentation consistent within the staggered setup.
What tire series are available for the 2025 Audi A6 Sportback e-tron?
Available tire series for the 2025 Audi A6 Sportback e-tron in 245/50R19 include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. Those series all fall within the correct 19-inch rear size for the Ultra Package application, but they are still distinct products rather than one tire sold under multiple names.
Comparing series is most useful after the fitment itself is settled. Start by confirming that the tire is for the 19-inch rear Ultra Package position, then compare the series alongside rim-width approval and other product-level details. That approach keeps the choice grounded in correct fitment first, which is especially important on a staggered front-and-rear vehicle.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2025 Audi A6 Sportback e-tron?
Yes, modifications can affect tire fitment on a 2025 Audi A6 Sportback e-tron, especially because the car uses staggered sizes and more than one wheel diameter. Aftermarket wheels, changes in wheel width or offset, suspension alterations, or lowering can all change how a front or rear tire sits in the wheelwell and how much clearance remains.
A modified car should be checked by actual wheel size and axle position before ordering replacements. It helps to verify front and rear diameters, wheel widths, and the tire sizes currently mounted rather than assuming the car still follows its original package. Clearance at steering lock and through suspension travel also deserves attention when the setup has been changed.
What should I inspect before driving a 2025 Audi A6 Sportback e-tron on new tires?
Before driving a 2025 Audi A6 Sportback e-tron on new tires, inspect that each tire matches the correct front or rear size, that wheel diameter is correct, and that inflation is set properly for the application. It also makes sense to look for proper bead seating, visible damage, uneven mounting issues, or any sign that a tire is not centered or clearing the surrounding components correctly.
A short, careful road check can reveal vibration, pull, or interference that is easier to correct early. On a staggered vehicle, double-check that the front and rear tires were not accidentally reversed during installation. Rechecking pressure after the first drive and confirming clearances at full steering lock can prevent small setup mistakes from becoming larger problems.
What should I check before a longer drive in a 2025 Audi A6 Sportback e-tron?
Before a longer drive in a 2025 Audi A6 Sportback e-tron, check tire pressure, tread condition, and the sidewalls for cuts, bulges, or other visible damage. Make sure the front and rear tires are the correct sizes for the car’s actual wheel package, since this model uses staggered fitment and can be equipped with either 19-inch or 20-inch wheels.
Longer trips put more value on catching small problems before they become roadside issues. It is also wise to look for uneven wear that could point to alignment or suspension concerns, particularly on a modern performance-oriented setup. Any recent wheel change, tire rotation attempt, or suspension work should prompt an extra fitment and clearance review before heading out.
