2025 Audi S5 Sportback (All-New) Tires

The 2025 Audi S5 Sportback (All-New) uses two primary tire sizes: 245/40R19 and 245/35R20. Both are radial fitments, and the correct size depends on the trim and wheel package rather than on a single universal setup across the whole model line.

The practical first step is checking whether the car has 19-inch or 20-inch wheels, then confirming the trim and package. Premium models use 245/40R19, while Black Optic Package and Edition One configurations use 245/35R20. Premium Plus and Prestige versions can appear with either size, so the actual wheel on the car matters.

A 2025 Audi S5 Sportback (All-New) uses either a 19-inch or 20-inch rim, depending on the tire size fitted to the car. The 245/40R19 size matches a 19-inch wheel, and the 245/35R20 size matches a 20-inch wheel.

That wheel diameter difference is the most important fitment checkpoint because tire sizes do not cross between 19-inch and 20-inch rims. Looking at the sidewall size marking on the current tire is usually the quickest confirmation. If the car has changed wheels since new, use the actual mounted wheel diameter rather than relying on trim name alone.

No. The 2025 Audi S5 Sportback (All-New) does not use one tire size across every sub-model. Some trims use 245/40R19, some use 245/35R20, and Premium Plus and Prestige configurations can be equipped with either size depending on the wheel setup.

That variation means the trim badge by itself is not always enough for ordering tires. Black Optic Package and Edition One versions stay on the 20-inch fitment, while Premium stays with the 19-inch size. On Premium Plus and Prestige cars, checking the existing sidewall marking or wheel diameter avoids ending up with the wrong rim fitment.

Start with the correct primary size for the car: 245/40R19 or 245/35R20. After that, compare tire construction, rim-width compatibility where stated, tire series, and whether the intended use leans more toward everyday street driving or a more aggressive performance-oriented setup.

The available choices stay within a blackwall radial performance theme, so the decision is less about appearance changes and more about matching the tire to the car’s wheel package and use. It also helps to compare details such as load figures where given and to keep all four tires consistent in size and general category.

Tires for the 2025 Audi S5 Sportback (All-New) are available from BFGoodrich and Nitto, depending on the size. BFGoodrich appears in both 245/40R19 and 245/35R20, while Nitto is available in the 245/35R20 fitment through the NT555 G2 series.

Brand choice should still come after confirming the correct wheel diameter and tire size for the car. Once that is settled, compare each brand’s available series in the proper size rather than assuming every brand offers the same fitment spread. That matters most on 20-inch cars, where there is more than one brand represented.

The 2025 Audi S5 Sportback (All-New) has access to several tire series within its two sizes, including BFGoodrich g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and Nitto NT555 G2. Series availability depends on whether the car uses the 19-inch or 20-inch fitment.

Comparing series is useful because it helps separate an all-season style choice from a more performance-focused one without leaving the correct size. The best approach is to narrow the fitment first, then compare the series that exist in that exact size. Looking at rim-width specs where shown can also help confirm wheel compatibility.

Yes. Even on a newer enthusiast car like the 2025 Audi S5 Sportback (All-New), correct tire fitment affects both appearance and the way the car sits on its wheels. Staying with the proper 245/40R19 or 245/35R20 size helps preserve the intended visual balance of the wheel and tire package.

This matters most when a car is being kept in especially original-looking condition or returned from an aftermarket wheel setup. A shorter-sidewall 20-inch package presents differently than the 19-inch setup, so mixing them carelessly changes the look. Any appearance-minded owner should confirm the exact trim and wheel package before replacing tires.

The available tires for the 2025 Audi S5 Sportback (All-New) use a blackwall sidewall style. That keeps the presentation clean, modern, and consistent with the car’s contemporary sport-luxury character rather than adding a contrasting stripe or raised-letter vintage look.

Because the fitment here is modern and performance-oriented, the bigger appearance decision is usually 19-inch versus 20-inch stance rather than sidewall decoration. Owners focused on an OEM-style presentation should make sure the size matches the wheel package already on the car. That keeps the proportions right without introducing a mismatched visual profile.

Yes. Modifications can affect tire fitment on a 2025 Audi S5 Sportback (All-New), especially if the car has aftermarket wheels, changes in wheel width, altered offset, suspension lowering, or body changes that reduce available clearance. Those factors can influence how a 245/40R19 or 245/35R20 tire sits in the wheel opening.

A car that remains on its original wheel package is simpler to match, but any modified setup should be checked carefully before replacement. Pay attention to wheel diameter first, then verify wheel width and clearance at full steering lock and full suspension travel. That approach helps avoid rubbing or mismatched fitment even when the tire size seems familiar.

Before driving on new tires, inspect the wheel size, confirm the tire size matches the car’s setup, and check that inflation is set correctly. It is also smart to look over the wheels for damage and make sure there are no obvious issues with alignment, suspension wear, or uneven old-tire wear patterns.

A short first drive should include attention to vibration, pull, rubbing, or unusual steering feel. After that, recheck pressure and visually confirm that each tire clears fenders and suspension components normally. On a performance-oriented car like the S5 Sportback, catching a wheel or setup issue early is better than assuming the new tires are the cause.

Tires on a 2025 Audi S5 Sportback (All-New) should be inspected regularly, not only when tread looks low. Routine checks should include pressure, tread condition, uneven wear, cuts, bulges, and any visible sidewall damage, especially on low-profile 35-series or 40-series fitments where impact damage can be easier to miss.

Monthly visual checks are a sensible habit, and any hard pothole strike or curb contact deserves an extra inspection right away. It also helps to check before a longer trip, since fastback sport sedans often see highway use where vibration or air loss becomes more noticeable. Early inspection can prevent a minor issue from becoming a wheel or tire failure.
