The 2016 Audi S7 sits at an interesting point in modern performance luxury, blending fastback styling, quattro all-wheel-drive confidence, and the kind of twin-turbo V8 punch that makes tire choice more than a routine maintenance decision. On this car, fitment starts with radial tires, but the exact size can vary across 19-, 20-, and 21-inch wheel setups. That means the real question is not simply finding an Audi S7 tire, but matching the correct size to the wheel on the car and then choosing among available blackwall, redline, or raised white letter options where offered. For a stock or modified S7 alike, wheel diameter confirmation comes first.
Which Tire Size Is Right for The 2016 Audi S7
The 2016 Audi S7 uses three primary tire sizes, and the difference begins with wheel diameter. This Base-model fitment spans 19-inch, 20-inch, and 21-inch setups, all in radial construction, so the first step is confirming which wheels are actually on the car before comparing tires. Once that is settled, the decision shifts to choosing the right tire style, series, and product characteristics within the correct size.
A 255/35R21 tire uses a 255-millimeter nominal section width, a 35-series aspect ratio, radial construction, and a 21-inch rim diameter. On a 2016 Audi S7, this is one of the modern low-profile fitments suited to a larger-diameter wheel package and a more contemporary performance presentation. The key point with this size is precision: the tire must match the 21-inch wheel exactly, and any substitute should be evaluated carefully for overall dimensions and clearance. This size is best approached by first confirming that the car still carries its 21-inch wheel setup.
A 255/40R19 tire keeps the same 255-millimeter nominal width but uses a taller 40-series profile on a 19-inch rim. For the 2016 Audi S7, this size opens up the broadest visible product choice here, including BFGoodrich and Pro-Trac offerings, with blackwall, redline, and raised white letter sidewall treatments across multiple series. That variety makes this size less about basic fitment and more about selecting the look and tire character that suits the car. Wheel width, sidewall style, and intended use are the main comparison points once the 19-inch diameter is confirmed.
A 265/35R20 tire is slightly wider than the 255-millimeter sizes, with a 35-series profile and a 20-inch rim diameter. On the 2016 Audi S7, it represents a distinct wheel-and-tire combination rather than a minor variation, so it should be matched to an actual 20-inch setup. Available choices in this size include blackwall, redline, and raised white letter styles from BFGoodrich, Nitto, and Pro-Trac, giving the buyer room to balance appearance with product preference. It is a size worth evaluating carefully on any S7 that has seen wheel changes or other modifications.
The covered 2016 Audi S7 sub-model fitment is straightforward because the Base model can use all three primary tire sizes. Even so, tire selection still depends on confirming whether the car is on 19-inch, 20-inch, or 21-inch wheels before choosing a product.

2016 Audi S7 Base
The 2016 Audi S7 Base uses radial tire fitments across three wheel diameters, so size choice is tied directly to the wheel package on the car rather than to a different trim level. That makes wheel confirmation the first step, followed by comparing tire series, sidewall style, and other product differences within the correct size.
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.

Common 2016 Audi S7 tire questions usually come down to identifying the correct size for the wheel diameter on the car, then comparing radial options by series, sidewall treatment, and fitment details that matter for road use.
Tire Size & Fitment
What tire size fits a 2016 Audi S7?
The 2016 Audi S7 uses three primary radial tire sizes: 255/40R19, 265/35R20, and 255/35R21. Those are not interchangeable as a single universal fitment, because each one corresponds to a different wheel diameter and overall wheel-and-tire setup on the car.
The right starting point is checking the wheel diameter currently on the S7. Once the car is confirmed to have 19-, 20-, or 21-inch wheels, tire selection becomes much easier, and attention can shift to the available tire series, sidewall style, and any wheel-width or clearance details that matter on a stock or modified setup.
What size rim does a 2016 Audi S7 use?
A 2016 Audi S7 can use 19-inch, 20-inch, or 21-inch rims, depending on which tire size is on the car. The matching fitments are 255/40R19 for 19-inch wheels, 265/35R20 for 20-inch wheels, and 255/35R21 for 21-inch wheels.
That rim diameter needs to be confirmed before ordering tires, especially on a car that may have changed hands or received aftermarket wheels. Reading the sidewall is helpful, but checking the actual wheel and current tire size together is the safest approach when the S7 could have been upgraded, downsized, or fitted with a seasonal wheel package.
Why does the 2016 Audi S7 have more than one tire size?
The 2016 Audi S7 has more than one tire size because it can be equipped with different wheel diameters. The Base model uses radial fitments in 19-inch, 20-inch, and 21-inch configurations, which creates multiple correct size paths rather than one single fitment for every car.
That means a buyer should not choose by year, make, and model alone without checking the actual wheel package. Tire size on an S7 is tied to the rim diameter first, and once that is known, the next step is comparing the available tires in that exact size for sidewall style, series, and compatibility with the car’s current setup.
Choosing the Right Tire
What should I consider when choosing a 2016 Audi S7 tire?
Start with the correct size for the wheel on the car, since the 2016 Audi S7 uses 255/40R19, 265/35R20, or 255/35R21 depending on wheel diameter. After that, compare radial tire construction details such as tire series, sidewall style, and any stated rim-width or load figures that apply to the specific product.
A stock S7 and a modified S7 can lead to different priorities, even within the same size. Some buyers want a straightforward blackwall performance look, while others may prefer redline or raised white letter styling, so the right choice comes down to matching appearance, wheel compatibility, and the way the car is actually used.
What sidewall styles are available for 2016 Audi S7 tires?
Available sidewall styles for the 2016 Audi S7 include blackwall, redline, and raised white letter options in the supported 19-inch and 20-inch sizes with product coverage. Blackwall choices appear across BFGoodrich and Nitto lines, while Pro-Trac adds redline and RWL styling in select sizes.
That gives the S7 owner a real appearance decision instead of a size-only decision. Blackwall usually keeps the look understated and modern, while redline or raised white letter treatment creates a more custom presentation, so the best choice depends on whether the car is being kept visually subtle or styled with a stronger period-inspired accent.
What brands offer tires for the 2016 Audi S7?
BFGoodrich, Nitto, and Pro-Trac all offer applicable radial tire choices for the 2016 Audi S7 in the supported product sizes shown here. BFGoodrich appears in both 255/40R19 and 265/35R20, Nitto appears in 265/35R20, and Pro-Trac appears in both sizes with multiple sidewall treatments.
Brand choice should be weighed alongside the exact tire series, wheel diameter, and the look you want from the car. Rather than treating the decision as a simple brand comparison, it makes more sense to confirm the correct size first and then compare the available products by sidewall style, rim-width suitability, and other visible specifications.
Restoration & Appearance
Which tire should I choose for a period-style 2016 Audi S7?
A period-style 2016 Audi S7 still begins with the correct modern radial size for the wheel on the car, whether that is 255/40R19, 265/35R20, or 255/35R21. From there, the visual direction comes from the product itself, especially in the 19-inch and 20-inch sizes where sidewall treatments go beyond a standard blackwall.
For an S7, period-style usually means preserving the character of a mid-2010s high-performance luxury car rather than chasing a vintage restoration formula. A blackwall tire keeps the presentation closer to contemporary OEM-style taste, while redline or raised white letter options shift the car toward a more personalized custom appearance.
How does tire construction affect the appearance of a restored 2016 Audi S7?
On a 2016 Audi S7, construction does not create the old bias-ply-versus-radial appearance decision seen on earlier collector cars, because the primary fitments here are radial. The visual difference comes more from size, wheel diameter, and sidewall treatment than from switching between historic and modern construction types.
That makes appearance selection more nuanced. A 19-inch or 20-inch setup with blackwall tires keeps the look clean and contemporary, while redline or raised white letter tires introduce a stronger styling statement, so owners focused on a restoration-minded presentation should decide whether they want understated factory-inspired character or a more customized finish.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Audi S7?
Yes, modifications can affect tire fitment on a 2016 Audi S7 even when the tire size itself is one of the accepted sizes. Aftermarket wheels, changes in wheel width, altered offsets, suspension lowering, or body changes can all influence clearance, steering range, and the amount of room available around the tire.
That is why a modified S7 should be checked as an individual setup rather than treated like a standard stock car. Confirm the wheel diameter first, then verify that the tire size, wheel width, and available space around the suspension and fenders still make sense before committing to a new set of tires.
What should I inspect before driving a 2016 Audi S7 on new tires?
Before driving a 2016 Audi S7 on new tires, inspect the wheels for damage, confirm that the tire size matches the rim diameter, and check inflation pressure, bead seating, and overall tire condition. It is also smart to look for any signs of rubbing potential around the fenders, inner liners, and suspension components.
A quick road-use check should include rechecking pressure after installation and paying attention to vibration, pull, or unusual contact sounds. On a performance-oriented car like the S7, correct fitment matters at both low and highway speeds, so catching a wheel, alignment, or clearance issue early can prevent larger problems after the tires are in service.
How often should tires on a 2016 Audi S7 be inspected?
Tires on a 2016 Audi S7 should be inspected regularly, not just when tread looks low. Look over them before longer drives and at routine intervals for air loss, cuts, bulges, cracking, uneven wear, and any damage that could affect a low-profile radial tire on 19-, 20-, or 21-inch wheels.
Consistent inspection matters even more if the car is driven infrequently or sits for long periods. A high-performance sedan can hide tire aging in plain sight, so checking condition, pressure, and wear pattern helps catch problems early and also confirms that the suspension, alignment, and wheel setup are still working properly with the chosen tire size.
