The 2025 Audi S4 carries the modern sport-sedan formula in a polished, all-weather package, blending everyday usability with the sharper reflexes enthusiasts expect from Audi’s S lineup. It is a car that rewards precise setup, and tire choice plays a major role in how it feels on the road. Every 2025 Audi S4 sub-model uses a 255/35R19 radial tire on a 19-inch rim, so the main decision is less about fitment variation and more about selecting the right tire within that size. Available choices center on blackwall BFGoodrich radial options across several g-Force series. That makes it important to balance road use, wheel compatibility, and the driving character you want from the car.
Which Tire Size Is Right for The 2025 Audi S4
The 2025 Audi S4 uses one primary tire size: 255/35R19, a modern radial fitment on a 19-inch rim. That same size carries across Premium, Premium Plus, and Prestige models, so the real decision is choosing the right tire within that fitment by comparing series, intended use, and wheel-width compatibility.
255/35R19 is a modern metric radial size. In plain terms, 255 refers to the tire’s nominal section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 19 is the wheel diameter in inches. On the 2025 Audi S4, this size supports the car’s low-profile, performance-oriented setup and keeps the selection focused on radial tire choices. Available options come from BFGoodrich in blackwall form across multiple g-Force series, giving you meaningful differences in tire character within the correct size. The important next step is matching the tire to your actual wheel width and intended street use.
Tire fitment is straightforward across the 2025 Audi S4 range because each covered sub-model uses the same primary tire size. Checking the exact trim still matters when confirming that the car remains on its original wheel setup and has not been altered with aftermarket wheels or suspension changes.

2025 Audi S4 Premium
The 2025 Audi S4 Premium uses the same 255/35R19 radial fitment as the rest of the S4 lineup covered here. That keeps tire selection focused on choosing among the available blackwall BFGoodrich radial options and confirming wheel-width compatibility before installation.
The 2025 Audi S4 Premium Plus also uses 255/35R19 radial tires on a 19-inch rim. The practical choice is comparing the available g-Force series within that size and making sure the wheel and overall vehicle setup still match the intended fitment.
The 2025 Audi S4 Prestige shares the same 255/35R19 radial tire size as the other covered S4 trims. That means the focus stays on tire series selection, wheel-width match, and verifying clearance if the car has been modified from its original configuration.
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 2025 Audi S4?
The 2025 Audi S4 uses a 255/35R19 radial tire. That size applies across Premium, Premium Plus, and Prestige sub-models, making fitment more straightforward than on vehicles that change tire size by trim or package.
Even with one primary size, it is still worth confirming the car’s actual wheel setup before choosing a tire. An S4 with aftermarket wheels, suspension changes, or a different staggered setup may need closer measurement of wheel width, clearance, and overall compatibility rather than relying on the original size alone.
What size rim does a 2025 Audi S4 use?
The 2025 Audi S4 uses a 19-inch rim with its primary 255/35R19 tire size. That rim diameter stays consistent across the covered S4 sub-models, so the tire and wheel pairing begins with confirming that the car is still on a 19-inch wheel.
Rim diameter is only one part of fitment, so wheel width still matters when comparing available tires. The current 255/35R19 options center around fitment for 8.5- to 10-inch wheel widths, which makes it smart to verify the actual wheel dimensions before installation on a modified or previously updated car.
Do all 2025 Audi S4 sub-models use the same tire size?
Yes. Premium, Premium Plus, and Prestige versions of the 2025 Audi S4 all use the same 255/35R19 radial tire size. That consistency simplifies replacement because the main fitment question is not trim-based size variation but choosing the right tire within the correct size.
That said, trim consistency does not override changes made by a previous owner or shop. A car fitted with non-original wheels, altered ride height, or a different wheel offset can change how a 255/35R19 tire sits, so a quick check of wheel specs and clearances remains a useful step before purchase.
Choosing the Right Tire
What should I consider when choosing a 255/35R19 tire for a 2025 Audi S4?
Start with the correct size, 255/35R19, and confirm that the tire matches the car’s 19-inch wheel setup. From there, compare the available radial options by tire series, wheel-width compatibility, load specification where stated, and the kind of road use the car will actually see.
A daily-driven S4 may call for a different balance than a car used mainly for spirited weekend driving. It also helps to check the exact wheel width on the car, since the available choices are intended for roughly 8.5- to 10-inch rims rather than every 19-inch wheel with the same diameter.
What sidewall styles are available for 2025 Audi S4 tires?
Current 255/35R19 options for the 2025 Audi S4 are offered in blackwall form. That suits the modern, understated look of the S4 and keeps the appearance consistent with the low-profile, performance-oriented character expected from a late-model Audi sport sedan.
Since there is no sidewall-style spread to sort through here, the more useful comparison is between tire series and specifications within the same blackwall presentation. That means focusing on how each option matches the car’s wheels, intended driving use, and the overall feel you want from the S4 on the road.
What tire series are available for the 2025 Audi S4?
The 2025 Audi S4 has 255/35R19 options in several BFGoodrich g-Force series, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. All are radial blackwall tires in the correct size, but they give the buyer more than one product line to compare.
Series choice matters because it helps distinguish the character of the tire even when size stays the same. Comparing wheel-width range, load specification where shown, and how the car is driven will usually be more useful than focusing on the size alone, since every option already begins with the correct 255/35R19 fitment.
Restoration & Appearance
Does correct tire fitment matter for a 2025 Audi S4 restoration or preservation project?
Yes. Even on a modern performance sedan like the 2025 Audi S4, staying with the correct 255/35R19 fitment helps preserve the intended stance, wheel-to-tire proportion, and overall presentation of the car. Correct fitment also keeps the visual balance of the 19-inch wheel package intact.
Appearance is only part of the equation, because preserving the car’s character also means verifying the actual wheels on the vehicle. An S4 that has been altered with different offsets, wheel widths, or suspension changes can look right at a glance while still needing a closer fitment check before new tires are installed.
How does tire choice affect the appearance of a 2025 Audi S4?
Tire choice has a visible effect on the 2025 Audi S4 because the 255/35R19 size uses a low-profile sidewall that strongly influences the car’s stance and wheel presentation. The currently available options are blackwall radials, which maintain the restrained, contemporary look expected from this generation of S4.
Since sidewall style does not vary here, the visual difference is more about keeping the correct size and proper wheel match than choosing decorative treatments. A tire that is correct in size but mismatched to wheel width or an altered suspension setup can change the car’s look and clearance, so those details deserve attention.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2025 Audi S4?
Yes. The 2025 Audi S4 uses a 255/35R19 tire, but modifications can still affect how that size fits in practice. Aftermarket wheels, changes in wheel width or offset, lowered suspension, and other chassis alterations can influence clearance at the fender, suspension, and steering components.
That is why a modified S4 should be measured rather than treated like a completely standard car. Even when the size stays the same, wheel specification and ride-height changes can alter the usable fitment envelope, so checking clearance through full steering travel and normal suspension movement is a sensible precaution.
What should I inspect before driving a 2025 Audi S4 on new tires?
Before driving a 2025 Audi S4 on new tires, inspect wheel condition, confirm the tire size is 255/35R19, and make sure the tires are mounted on appropriate 19-inch wheels. It also helps to check inflation, valve stems, tread and sidewall condition, and whether the wheels were balanced correctly.
A short post-installation check is just as important on a performance sedan. After a brief drive, recheck pressure, look for any rubbing marks, and pay attention to vibration or pulling that could point to alignment, balance, or wheel-fitment issues rather than the tire size itself.
How often should tires on a 2025 Audi S4 be inspected?
Tires on a 2025 Audi S4 should be inspected regularly, not just when tread looks low. A performance-oriented low-profile size like 255/35R19 benefits from routine checks for uneven wear, cuts, punctures, sidewall damage, and pressure loss, especially if the car sees fast highway use or rough pavement.
Monthly visual checks are a practical habit, with a closer inspection before longer trips or any spirited driving. It is also wise to inspect sooner after impacts with potholes or curbs, since wheel damage, alignment changes, or hidden sidewall issues can affect how the car drives even when the tire still holds air.
