The 2023 Audi RS5 Sportback blends modern Audi performance with four-door fastback practicality, giving owners a car that feels equally at home on a back road or a long highway run. Its sharp styling and high-output personality make tire choice more than a routine replacement decision. This model uses radial tire fitments in either 265/35R19 or 275/30R20, depending on the exact configuration. That means the key question is not only size, but also confirming wheel diameter and then comparing available performance-oriented options within the correct fitment. For this RS5 Sportback, the right choice comes down to matching the tire to the sub-model, wheel setup, and intended road use.
Which Tire Size Is Right for The 2023 Audi RS5 Sportback
The 2023 Audi RS5 Sportback uses two primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. The Base model uses a 19-inch setup, while the Black Optic Pkg. and w/Competition Pkg. use a 20-inch setup. Before choosing a tire, confirm which package the car has and verify whether it is still running its original wheel diameter.
A 265/35R19 tire uses a 265-millimeter section width, a 35-series aspect ratio, radial construction, and a 19-inch rim. On the 2023 Audi RS5 Sportback, this size serves the Base configuration and reflects a modern low-profile performance fitment. Available choices in this size include BFGoodrich and Nitto options, all in Blackwall form, with series such as g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This is the size to evaluate when the car retains its 19-inch wheel package and the goal is selecting among comparable radial performance tires rather than changing wheel diameter.
A 275/30R20 tire uses a 275-millimeter section width, a 30-series aspect ratio, radial construction, and a 20-inch rim. On the 2023 Audi RS5 Sportback, this size applies to the Black Optic Pkg. and w/Competition Pkg., making wheel confirmation especially important before replacement. The available product choice in this size centers on a Blackwall Nitto NT555 G2, which keeps the focus on matching the correct fitment rather than comparing many cosmetic variations. This size should be considered when the car is equipped with the 20-inch package and clearance-sensitive low-profile fitment needs to remain consistent.
Sub-model fitment matters on the 2023 Audi RS5 Sportback because tire size changes with the wheel package. The first step is confirming whether the car is a Base model or one of the 20-inch package configurations before comparing tire choices.

2023 Audi RS5 Sportback Base
The 2023 Audi RS5 Sportback Base uses the 265/35R19 radial fitment on a 19-inch wheel. Tire selection here is mainly about choosing among the available performance-oriented Blackwall options while keeping the original wheel diameter and low-profile sizing in mind.
The 2023 Audi RS5 Sportback Black Optic Pkg. uses the 275/30R20 radial fitment on a 20-inch wheel. That makes wheel confirmation especially important, since moving between 19-inch and 20-inch tire sizes is not simply a matter of choosing a different tire.
The 2023 Audi RS5 Sportback w/Competition Pkg. also uses the 275/30R20 radial fitment. For this configuration, the focus is on preserving the correct 20-inch setup and checking that any replacement tire matches the car's current wheel and clearance requirements.
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 2023 Audi RS5 Sportback?
The 2023 Audi RS5 Sportback uses two tire sizes: 265/35R19 and 275/30R20. The Base model uses 265/35R19, while the Black Optic Pkg. and w/Competition Pkg. use 275/30R20. Both are radial fitments, but they are tied to different wheel diameters and configurations within the RS5 Sportback lineup.
The practical step is identifying the exact sub-model and confirming the wheel diameter currently on the car. A 19-inch tire and a 20-inch tire are not interchangeable without the matching wheel, so package identification matters before comparing brands, tread designs, or other product details.
What size rim does a 2023 Audi RS5 Sportback use?
A 2023 Audi RS5 Sportback uses either a 19-inch or 20-inch rim, depending on the sub-model. The Base model uses the 265/35R19 fitment on a 19-inch rim, while the Black Optic Pkg. and w/Competition Pkg. use 275/30R20 on a 20-inch rim.
Rim diameter should be confirmed before ordering tires, especially on a car that may have seen wheel changes after delivery. Even if the overall look seems similar, the tire must match the actual wheel diameter on the vehicle, and low-profile performance fitments leave less room for sizing mistakes.
Why does the 2023 Audi RS5 Sportback have more than one tire size?
The 2023 Audi RS5 Sportback has more than one tire size because different sub-model configurations use different wheel packages. The Base model is paired with 265/35R19, while the Black Optic Pkg. and w/Competition Pkg. are paired with 275/30R20. The change is tied to the vehicle's package-specific wheel setup rather than a random tire substitution.
That means the right tire is determined by the car's exact configuration and present wheel diameter, not simply by the model name on the trunk. Verifying the package and checking the tire sidewall or wheel size before replacement helps avoid ordering a tire that matches the model family but not the actual setup.
Choosing the Right Tire
What should I consider when choosing a tire for a 2023 Audi RS5 Sportback?
Start with the correct size for the specific car: 265/35R19 for the Base model or 275/30R20 for the Black Optic Pkg. and w/Competition Pkg. From there, compare construction, brand, tire series, and any useful specifications such as rim-width compatibility, weight, or load information where those details are available.
The best comparison is one that keeps fitment first and then matches the tire to how the car is actually driven. A daily-driven RS5 Sportback, a fair-weather performance car, and a lightly used weekend car can all call for slightly different priorities, but none of those choices should override the correct size and wheel match.
What sidewall styles are available for 2023 Audi RS5 Sportback tires?
The available tires for the 2023 Audi RS5 Sportback use a Blackwall sidewall style. That applies to both the 265/35R19 and 275/30R20 fitments in the current product selection. For this vehicle, the visible differences between choices come more from brand and tire series than from contrasting sidewall treatments.
That is typical of modern high-performance fitments, where the appearance is usually clean and understated rather than focused on whitewalls or vintage lettering treatments. Once the correct size is confirmed, owners can compare the remaining details in the product grid without needing to sort through multiple cosmetic sidewall formats.
What brands offer tires for the 2023 Audi RS5 Sportback?
BFGoodrich and Nitto offer tires for the 2023 Audi RS5 Sportback. In 265/35R19, the available choices include BFGoodrich and Nitto, while the 275/30R20 fitment is represented by Nitto. The available series include g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2.
Brand choice should still come after size and wheel confirmation, since the Base model and the 20-inch package cars do not use the same tire size. Once the correct fitment is established, comparing series, sidewall style, and any published rim-width or load details will usually be more useful than choosing by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2023 Audi RS5 Sportback?
A period-style approach on a 2023 Audi RS5 Sportback usually means staying with the original size family and wheel diameter used by the specific sub-model. That means 265/35R19 on the Base model or 275/30R20 on the Black Optic Pkg. and w/Competition Pkg., while keeping the modern radial, low-profile appearance intact.
Because this is a recent high-performance Audi, appearance is shaped more by preserving the intended stance and wheel-and-tire proportion than by vintage sidewall styling. Owners aiming for a clean, authentic presentation should focus on matching the car's package-specific fitment and avoiding substitutions that alter the visual balance of the setup.
Does correct tire fitment matter for a 2023 Audi RS5 Sportback restoration?
Correct tire fitment matters on a 2023 Audi RS5 Sportback because the tire is part of the car's overall stance, wheel presentation, and performance character. Using the proper 19-inch or 20-inch fitment for the exact sub-model helps preserve the intended look rather than introducing a mismatch in sidewall height or wheel proportion.
Even on a newer collector-oriented vehicle, small changes in fitment can alter how the car sits and how complete it looks. Anyone returning an RS5 Sportback to a more original-style presentation should verify the package-specific wheel setup first, then choose a tire that keeps the correct size relationship in place.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Audi RS5 Sportback?
Yes, modifications can affect tire fitment on a 2023 Audi RS5 Sportback. Aftermarket wheels, suspension changes, ride-height adjustments, or body modifications can alter the clearance available for either the 265/35R19 or 275/30R20 fitment. Even when the tire size remains the same on paper, wheel width and offset changes can affect how the tire sits.
That is why the current setup should be checked before ordering replacements, especially on a performance car with low-profile tires. Wheel diameter, width, and clearance at full steering lock all matter, and any non-original changes should be taken into account before assuming the original sub-model tire size still applies unchanged.
What should I inspect before driving a 2023 Audi RS5 Sportback on new tires?
Before driving a 2023 Audi RS5 Sportback on new tires, inspect the wheel diameter, tire size, inflation pressure, and general installation quality. It is also wise to look for any obvious clearance concerns, verify that the tires are seated properly, and make sure there are no cuts, bulges, or visible damage from handling or mounting.
A short, careful road test helps confirm that the car tracks properly and that nothing rubs under steering or suspension movement. On a low-profile fitment, small issues are easier to notice early, so it pays to recheck pressure and do a quick visual inspection again after the first few drives.
How often should tires on a 2023 Audi RS5 Sportback be inspected?
Tires on a 2023 Audi RS5 Sportback should be inspected regularly, not just when tread wear becomes obvious. A performance-oriented car benefits from frequent checks for air loss, uneven wear, sidewall damage, embedded debris, and any signs that the tire has been contacting suspension or body components.
Regular inspection matters even more if the car is driven seasonally or sits for long periods between outings. Checking pressure, tread condition, and overall sidewall health before longer drives can catch problems early and helps confirm that the tires are still suitable for the car's speed, weight, and intended use.
