2023 Audi S5 Sportback Tires

The 2023 Audi S5 Sportback uses two tire sizes: 255/35R19 and 265/30R20. The 255/35R19 size applies to Premium, Premium Plus, and Prestige trims, while the 265/30R20 size applies to Premium Plus w/Black Optic Pkg. and Prestige w/Black Optic Pkg.

The practical step is matching the tire to the car’s actual wheel package, not just the model name on the trunk. A quick check of the existing tire sidewall and wheel diameter helps prevent ordering the wrong profile, especially since the 19-inch and 20-inch setups are both correct for different versions of the same vehicle.

A 2023 Audi S5 Sportback uses either a 19-inch or 20-inch rim, depending on the sub-model and package. The 255/35R19 fitment pairs with a 19-inch rim, while the 265/30R20 fitment pairs with a 20-inch rim.

Rim diameter should be confirmed before any tire purchase because a 19-inch tire cannot be mounted on a 20-inch wheel, and the reverse is equally true. It is also smart to verify the wheel currently on the car, since some vehicles receive replacement wheels after delivery and the existing setup may differ from the original trim configuration.

No. The 2023 Audi S5 Sportback has split fitment across its sub-models. Premium, Premium Plus, and Prestige use 255/35R19, while Black Optic Package versions of Premium Plus and Prestige use 265/30R20.

That difference matters because the tire choice follows the wheel package, not a one-size-fits-all rule for every S5 Sportback. Buyers replacing a single tire set should confirm the exact trim and inspect the current tire sidewall so the replacement matches the car’s existing diameter and profile rather than assuming all versions are the same.

Start with the correct size, radial construction, and 19-inch wheel fitment. In 255/35R19, available choices include BFGoodrich performance-oriented options in the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series, all with blackwall styling.

The next step is comparing the product details that affect how the tire suits the car’s setup, including rim-width range, weight, and load-related specifications where shown. That keeps the focus on finding the right tire within the correct fitment rather than treating every 255/35R19 as identical in character or intended use.

For the currently available 255/35R19 fitment, the sidewall style is blackwall. That gives the 2023 Audi S5 Sportback a clean, modern presentation that fits the car’s sport-luxury character without introducing period-style or specialty sidewall treatments.

Sidewall choice affects appearance as much as fitment, especially on a late-model performance car where wheel and tire proportions are visually prominent. When comparing options, it helps to keep the look consistent across all four tires and to confirm that the tire’s overall specifications still match the correct size and wheel package for the trim.

In the 255/35R19 size, the 2023 Audi S5 Sportback has BFGoodrich options in three tire series: g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. Each is a radial blackwall tire built around a performance-oriented product family.

Series names help separate the available choices when the size itself stays the same. A buyer comparing them should look past the shared 255/35R19 fitment and review details such as rim-width range, weight, and load capacity information where shown so the selected tire matches both the wheel and the car’s intended street use.

A 2023 Audi S5 Sportback is better approached as a modern OE-style fitment exercise than a period-style restoration project. The key is staying with the correct current size for the specific trim, either 255/35R19 or 265/30R20, and selecting a radial tire that matches the car’s wheel package and overall character.

Appearance still matters, especially on a sportback with large wheels and low-profile tires. A blackwall tire keeps the look contemporary and in step with the car’s design, while the right profile preserves the visual balance between tire, wheel, and body line rather than making the car look under- or over-tired.

Yes. Even on a recent performance luxury model, correct tire fitment has a major effect on appearance, stance, and how complete the vehicle looks. The difference between the 19-inch 255/35R19 setup and the 20-inch 265/30R20 setup is immediately visible because sidewall height and wheel diameter change together.

An appearance-focused build should begin with the exact trim and wheel package already on the car. Matching the proper size helps preserve the intended proportions, while an incorrect profile can upset the visual balance and may create clearance or mounting issues that are unnecessary when the right fitment is chosen from the start.

Yes. Modifications such as aftermarket wheels, offset changes, suspension lowering, or body alterations can affect tire fitment on a 2023 Audi S5 Sportback even when the tire size looks close to stock. That matters because this model already uses low-profile radial sizes that leave less room for error.

A modified car should be checked for wheel diameter, wheel width, steering clearance, and fender clearance before replacement tires are chosen. Even if the car started life with 255/35R19 or 265/30R20, a later wheel or suspension change can alter what fits comfortably, especially during turning, compression, or full-load driving.

Before driving on new tires, inspect inflation pressure, mounting direction where applicable, valve condition, wheel condition, and overall clearance around the suspension and fenders. It is also wise to confirm that all four tires match the intended size for the car’s trim and wheel package.

A short initial road check can reveal vibration, rubbing, or steering issues before the car is used more aggressively. After that first drive, recheck pressure and look for any signs of contact or uneven seating, since low-profile fitments on 19-inch and 20-inch wheels leave less visual sidewall cushion than taller traditional sizes.

Tires on a 2023 Audi S5 Sportback should be inspected regularly rather than only when tread looks low. Frequent checks for pressure loss, cuts, bulges, irregular wear, and sidewall damage are especially important on low-profile performance sizes because damage can be easier to miss until ride or handling changes appear.

A practical routine is to inspect the tires during washing, before longer trips, and anytime the car feels different on the road. Cars that sit for stretches still need attention, since air loss, curb damage, and age-related deterioration can affect a modern radial tire even when annual mileage is relatively modest.
