The 2023 Audi S4 sits in the modern sport-sedan sweet spot, blending everyday refinement with the sharper road manners that have long defined Audi’s S models. It is a car that rewards precise setup, and tire choice plays a major role in preserving that balance of grip, response, and ride quality. This S4 uses a 255/35R19 radial tire on a 19-inch rim, giving owners one clear primary fitment to work from across the model range. Available choices center on Blackwall BFGoodrich performance-oriented radial offerings in several g-Force series. The real decision is how closely the tire’s character matches the way the car is driven and the exact wheel setup on the vehicle.
Which Tire Size Is Right for The 2023 Audi S4
The 2023 Audi S4 uses one primary tire size: 255/35R19, a radial fitment for a 19-inch rim. That same size carries across Premium, Premium Plus, and Prestige models, so the main decision is not which primary size fits, but which tire within that size best suits the car’s road use, wheel width, and overall performance priorities.
A 255/35R19 tire uses a 255-millimeter nominal section width, a 35-series aspect ratio, radial construction, and a 19-inch rim diameter. On the 2023 Audi S4, that low-profile radial format matches the car’s modern sport-sedan character and keeps tire selection centered on responsive street performance rather than vintage-style construction choices. Available options in this size come from BFGoodrich in Blackwall form across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. Choosing among them means confirming wheel width, comparing tire character within the same size, and matching the tire to how the S4 is actually used.
Tire fitment is straightforward across the covered 2023 Audi S4 sub-models because each one uses the same primary tire size. Checking the exact trim still matters when confirming the vehicle’s present wheel setup, especially if the car has been changed from its original wheel and tire combination.

2023 Audi S4 Premium
The 2023 Audi S4 Premium uses the same 255/35R19 radial tire size as the other covered S4 trims. That keeps selection focused on choosing the right performance tire within that size and confirming that the wheel width remains suitable for the tire being considered.
The 2023 Audi S4 Premium Plus also uses 255/35R19 radial tires on a 19-inch rim. For this trim, the buying decision centers on tire series and road-use priorities rather than changing between multiple primary fitment sizes.
The 2023 Audi S4 Prestige shares the same 255/35R19 radial fitment found on the other listed S4 sub-models. That consistency makes tire choice easier, but it is still worth confirming the actual wheels on the car before selecting among the available 19-inch performance radials.
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.
Best 2023 Audi S4 Tires for Sale
Available 255/35R19 choices for the 2023 Audi S4 center on BFGoodrich Blackwall radials in several g-Force series. The main product differences are tire series, weight, load specification where stated, and compatible rim-width range within the same 19-inch fitment.
These 2023 Audi S4 tire FAQs focus on the 255/35R19 fitment, 19-inch rim compatibility, performance-oriented radial choices, trim consistency, and the inspection steps that matter before regular road use or a longer drive.
Tire Size & Fitment
What tire size fits a 2023 Audi S4?
The 2023 Audi S4 uses a 255/35R19 radial tire size. That primary fitment appears across Premium, Premium Plus, and Prestige models, making tire selection more straightforward than on vehicles that change size by trim or package.
The practical next step is confirming that the car still has the expected 19-inch wheel setup. If the S4 has aftermarket wheels or a changed suspension height, the correct primary size may still be 255/35R19, but wheel width, clearance, and the exact tire model should be checked before final selection.
What size rim does a 2023 Audi S4 use?
The 2023 Audi S4 uses a 19-inch rim with its 255/35R19 tire size. Available tires in this fitment are built for that 19-inch wheel diameter, so the rim diameter itself is not an area where this page shows multiple primary choices.
Rim diameter is only one part of the fitment picture, though. Wheel width matters too, and the available 255/35R19 products here call for rims in the 8.5- to 10-inch range, so the actual wheel on the car should be measured or confirmed before choosing among the options.
Do all 2023 Audi S4 sub-models use the same tire size?
Yes. The covered 2023 Audi S4 Premium, Premium Plus, and Prestige sub-models all use the same 255/35R19 radial tire size. That means trim level does not create a separate primary tire-size decision within this group of S4 models.
Even with shared fitment, it is still smart to inspect the car itself before ordering tires. Previous owners may have changed wheels, altered ride height, or installed a different tire size, and those changes can affect clearance, handling balance, and which 255/35R19 tire works best on the vehicle.
Choosing the Right Tire
What should I consider when choosing a 255/35R19 tire for a 2023 Audi S4?
Start with the correct primary size, which is 255/35R19, then compare the available radial tire series within that fitment. For the 2023 Audi S4, the main differences are performance-oriented product line, Blackwall styling, stated load specification where given, weight, and rim-width compatibility.
A good selection process matches the tire to the way the car is used. A daily-driven S4, a weekend back-road car, and a modified sedan on wider wheels may all point toward different preferences within the same size, so wheel width and intended driving use should be confirmed before deciding.
What sidewall styles are available for 2023 Audi S4 tires?
The available 255/35R19 tires for the 2023 Audi S4 are offered in Blackwall form. That gives the car a clean modern appearance that suits the S4’s contemporary sport-sedan design without introducing vintage-style sidewall treatments.
Since the sidewall presentation stays consistent here, the larger choice comes from the tire series itself rather than appearance variation. That simplifies the buying process, because the owner can focus on fitment details, wheel width, and the driving character of each radial option instead of sorting through multiple sidewall styles.
What tire series are available for the 2023 Audi S4?
The 2023 Audi S4 has 255/35R19 tire options in BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. All are radial Blackwall tires in the same basic fitment, so the differences come from the series and product specification rather than a change in primary size.
Comparing series is useful because it helps separate one tire’s intended character from another while staying within the correct size. It is worth reviewing wheel-width compatibility, load information where stated, and the role the car plays in regular driving so the selected series matches the S4’s use.
Restoration & Appearance
Which tire should I choose for a period-style 2023 Audi S4?
A period-style approach on a 2023 Audi S4 still starts with the correct modern primary fitment, which is 255/35R19. Because this is a contemporary performance sedan rather than a vintage restoration candidate, the focus is less about antique appearance and more about keeping the car’s wheel-and-tire proportions appropriate to its original-era presentation.
That usually means staying with the proper low-profile radial size and a clean Blackwall look. Selection then becomes a matter of choosing the tire series that best fits the car’s use while avoiding unnecessary departures in wheel width, stance, or tire profile that can change the S4’s intended visual balance.
Does correct tire fitment matter for a 2023 Audi S4 restoration or preservation project?
Yes, correct tire fitment still matters on a 2023 Audi S4 being preserved in close-to-original form. The proper 255/35R19 size helps maintain the car’s intended stance, wheel fill, and modern sport-sedan proportions in a way that an obviously different profile or diameter may not.
Owners interested in preservation should also pay attention to details beyond size alone. Wheel width, tire series, and the understated Blackwall appearance all influence how authentic the finished result feels, especially on a modern Audi where visual correctness often comes from restraint rather than decorative sidewall styling.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Audi S4?
Yes. A 2023 Audi S4 may use the correct 255/35R19 tire size on paper, but modifications such as aftermarket wheels, changes in wheel offset, lowering springs, suspension work, or body alterations can all affect real-world fitment and clearance.
That is why the actual car should be checked before selecting a tire, especially if it has been customized. Steering clearance, inner-fender room, and wheel width all matter, and those factors can influence which tire model within the correct size is the most sensible choice for the vehicle.
What should I inspect before driving a 2023 Audi S4 on new tires?
Before driving a 2023 Audi S4 on new tires, inspect wheel condition, confirm proper inflation, and make sure each tire is mounted on the correct 19-inch wheel width. It is also smart to check for suspension wear, alignment issues, and any signs that previous tires rubbed under steering or compression.
A short initial road test helps confirm that the car tracks cleanly and that there is no contact at full steering lock or over bumps. After a few miles, recheck tire pressure and give the tires a visual inspection so early mounting or clearance issues can be caught promptly.
What should I check before a longer drive in a 2023 Audi S4?
Before a longer drive, check the 2023 Audi S4’s tire pressure, tread condition, sidewalls, and overall wheel-and-tire condition. Look for cuts, bulges, irregular wear, or slow air loss, and make sure the 255/35R19 tires are in sound condition for sustained highway use.
Longer trips also make it worthwhile to verify alignment feel and confirm there is no vibration that could point to a balance or wheel issue. On a performance sedan like the S4, small tire problems can become much more noticeable at speed, so a careful pre-drive inspection is time well spent.
