The 2016 Audi S5 sits in the modern grand-touring side of Audi performance, blending sharp coupe and cabriolet styling with the kind of everyday drivability that makes tire choice especially important. It is a car that rewards the right stance, grip, and rim fitment rather than a one-size-fits-all approach. For this exact S5, primary fitment stays radial throughout, but the tire size can be 245/40R18, 255/35R19, or 265/30R20 depending on the sub-model and wheel setup. That opens the door to choices in blackwall, redline, and raised white letter presentation, along with several performance-oriented tire series. The key is matching the exact size to the car’s wheel diameter and intended use before comparing appearance or driving character.
Which Tire Size Is Right for The 2016 Audi S5
The 2016 Audi S5 uses three primary tire sizes, and the right one depends first on the exact sub-model and wheel diameter. All three are radial fitments, but they span 18-inch, 19-inch, and 20-inch rims, so confirming the wheels on the car is the first step before comparing tire series, sidewall style, or road-use priorities.
Fit(s): Premium Plus Cabriolet, Premium Plus Coupe, Prestige Cabriolet, and Prestige Coupe
Construction: Radial|Rim: 18 in
245/40R18 is a metric radial size in which 245 identifies the section width in millimeters, 40 is the aspect ratio, R marks radial construction, and 18 is the rim diameter in inches. On the 2016 Audi S5, this size is one of the primary fitments and keeps the buyer in a modern low-profile radial format. Available choices include blackwall performance tires as well as redline and raised white letter versions in the Street Pro III series. It is the size to evaluate when the car is equipped with 18-inch wheels and you want to balance correct fitment with the appearance and use that suits the car best.
Fit(s): Premium Plus Cabriolet, Premium Plus Coupe, Prestige Cabriolet, and Prestige Coupe
Construction: Radial|Rim: 19 in
255/35R19 uses the same metric radial convention, with a 255-millimeter section width, a 35-series profile, and a 19-inch rim diameter. This size is a primary fitment for the 2016 Audi S5 and represents a lower-profile setup than the 18-inch option while remaining in the same general performance-focused format. Choices here center on blackwall tires from BFGoodrich across several g-Force series. It is the right size to consider only when the S5 is riding on 19-inch wheels, since wheel diameter confirmation matters before comparing series character or other specifications.
265/30R20 is a metric radial size with a 265-millimeter section width, a 30-series profile, and a 20-inch rim diameter. For the 2016 Audi S5, this size appears on specific coupe configurations and represents the largest wheel-and-tire combination among the primary fitments. Its role is distinct from the 18-inch and 19-inch setups because the rim diameter changes, making wheel confirmation essential before any tire selection begins. Buyers considering this size should focus on whether the car is equipped with the correct 20-inch wheels and whether the existing setup leaves appropriate clearance for the intended use.
Sub-model fitment matters on the 2016 Audi S5 because the covered configurations do not all use the same tire-size range. Cabriolet models use 18-inch or 19-inch fitments, while coupe models can also use a 20-inch setup, so identifying the exact sub-model and wheel diameter comes first.

2016 Audi S5 Premium Plus Cabriolet
The 2016 Audi S5 Premium Plus Cabriolet uses radial tire fitments in 245/40R18 or 255/35R19. Tire selection starts with confirming whether the car has 18-inch or 19-inch wheels, then narrowing the choice by tire series, sidewall presentation, and the kind of road use the car will actually see.
The 2016 Audi S5 Premium Plus Coupe has the widest fitment spread of the group, using radial sizes in 245/40R18, 255/35R19, or 265/30R20. That makes wheel diameter the critical first check, followed by a close look at whether the tire choice is aimed at street performance, appearance, or a more specialized use.
The 2016 Audi S5 Prestige Cabriolet uses radial tire fitments in 245/40R18 or 255/35R19. Once the wheel diameter is confirmed, the decision becomes more straightforward and centers on choosing among the available performance-oriented tires and any sidewall styling that suits the look of the car.
The 2016 Audi S5 Prestige Coupe uses radial tire sizes in 245/40R18, 255/35R19, or 265/30R20. Because this coupe can span three rim diameters, a buyer should verify the actual wheel setup on the car before comparing tire construction details, series differences, or appearance-focused options.
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:

Common 2016 Audi S5 tire questions usually come down to matching the right size to the wheel and sub-model, then comparing radial tire choices by series, sidewall style, and intended use. The answers below focus on fitment, selection, and practical checks before road use.
Tire Size & Fitment
What tire size fits a 2016 Audi S5?
A 2016 Audi S5 uses one of three primary radial tire sizes: 245/40R18, 255/35R19, or 265/30R20. The correct size depends on the exact sub-model and, just as importantly, the wheel diameter on the car. Cabriolet versions use 18-inch or 19-inch fitments, while coupe versions can also use a 20-inch setup.
The practical first step is to confirm the wheels actually installed on the vehicle rather than assuming every S5 uses the same size. Once the rim diameter is verified, the tire decision becomes much easier and shifts toward comparing available tire series, sidewall styling, and whether the car is being kept close to its present setup or used in a more specialized way.
What size rim does a 2016 Audi S5 use?
The 2016 Audi S5 uses 18-inch, 19-inch, or 20-inch rims, depending on the tire size and sub-model. The three primary fitments are 245/40R18 on an 18-inch rim, 255/35R19 on a 19-inch rim, and 265/30R20 on a 20-inch rim. All are radial tire applications.
Rim diameter is the most important fitment checkpoint because each tire size is built for a specific wheel diameter. A buyer should verify the actual wheels on the car before selecting a tire, especially on used vehicles where wheel packages may have changed over time. Confirming wheel width is also worthwhile when comparing specific tire options within the same diameter.
Do all 2016 Audi S5 sub-models use the same tire size?
No. The 2016 Audi S5 sub-models do not all use the same tire size range. Premium Plus Cabriolet and Prestige Cabriolet models use 245/40R18 or 255/35R19, while Premium Plus Coupe and Prestige Coupe models can use 245/40R18, 255/35R19, or 265/30R20.
That difference matters because the coupe range extends to a 20-inch fitment that does not apply across the cabriolet lineup. Identifying the exact sub-model keeps the search focused and helps avoid choosing a tire built for the wrong wheel diameter. On any S5 that has been modified, the actual wheel-and-tire setup on the car should still be checked before ordering.
Choosing the Right Tire
What should I consider when choosing a 245/40R18 tire for a 2016 Audi S5?
A 245/40R18 tire for a 2016 Audi S5 should first be chosen by confirming that the car is on 18-inch wheels, then by comparing construction details, intended use, and appearance. Available options in this size include blackwall performance tires, a drag-oriented radial, and Street Pro III versions with redline or raised white letter sidewalls.
That means the choice is not just about size. Some buyers may want a clean modern blackwall look, while others may prefer a more distinctive sidewall treatment. It also helps to compare rim-width compatibility, load figures where stated, and whether the car is used primarily for street driving, occasional spirited use, or a more specialized setup such as straight-line performance.
What sidewall styles are available for 2016 Audi S5 tires?
Sidewall styling for the 2016 Audi S5 varies by tire size, with the broadest variety appearing in 245/40R18. In that size, blackwall, redline, and RWL, or raised white letter, options are available. The 255/35R19 choices stay in blackwall form among the current product selection.
Sidewall style mostly affects appearance, but it can be an important part of how the car presents itself. A blackwall keeps the look understated and contemporary, while redline or raised white letters add a stronger visual statement. The main thing is to choose the correct tire size and wheel diameter first, then narrow the final decision by the sidewall treatment that best suits the car.
What brands offer tires for the 2016 Audi S5?
Tires for the 2016 Audi S5 are available from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac within the current size range. Brand choice varies by size, with 245/40R18 carrying the widest spread of options and 255/35R19 centered on BFGoodrich performance-oriented tires.
Brand alone should not make the decision. It is more useful to compare the exact tire series, the available sidewall treatment, and whether the tire’s character matches how the S5 is driven. Checking rim-width compatibility and the details of the installed wheel package helps narrow the field further, especially when more than one tire has the correct size designation.
Restoration & Appearance
Which tire should I choose for a period-style 2016 Audi S5?
A period-style 2016 Audi S5 tire choice usually starts with keeping the correct primary size for the car’s wheel diameter, then selecting a tire whose visual presentation suits the look you want. In 245/40R18, that may mean choosing between a modern blackwall, a redline, or a raised white letter version rather than focusing only on performance branding.
Because the S5 is a modern performance car, appearance decisions often come down to whether the goal is a clean OEM-like presentation or a more customized enthusiast look. The safest approach is to confirm the exact wheel setup first and then choose the sidewall style and tire series that support the car’s visual direction without drifting away from the proper fitment.
How does tire construction affect the appearance of a restored 2016 Audi S5?
On a 2016 Audi S5, construction does not create a bias-ply-versus-radial decision because the primary fitments are radial throughout. The appearance difference comes more from the tire series and sidewall treatment than from construction type. In practical terms, a blackwall radial presents differently from a redline or raised white letter radial in the same size.
That makes visual selection more nuanced than simply choosing the correct dimensions. Buyers aiming for a refined, contemporary look may stay with a plain blackwall, while others may want a sidewall detail that gives the car a more personalized stance. The tire should still match the exact rim diameter and size range used by the specific S5 configuration.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Audi S5?
Yes. Modifications can affect tire fitment on a 2016 Audi S5 even when the tire size appears close to one of the standard options. Aftermarket wheels, changes in wheel width or offset, suspension lowering, and body or brake-package changes can all alter the space available around the tire.
A modified S5 should be checked for actual wheel diameter, wheel width, and clearance at full steering lock and suspension movement before a tire is selected. That matters most when moving between the 18-inch, 19-inch, and 20-inch fitment ranges. Looking at the present setup on the car is more reliable than assuming it still follows its original sub-model configuration.
What should I inspect before driving a 2016 Audi S5 on new tires?
Before driving a 2016 Audi S5 on new tires, inspect the wheel condition, verify proper inflation, and make sure the tire size matches the rim diameter on the car. It is also smart to look over valve stems, check that the tires seat evenly, and confirm there is no rubbing against suspension, brake, or fender components.
An S5 with low-profile tires benefits from a careful recheck after the first few drives. Air pressure, visible clearance, and any vibration or pull should be watched closely as the tires settle in. On a used or recently modified car, alignment and wheel-balance issues can show up quickly, so early attention helps protect both the tires and the driving feel.
How often should tires on a 2016 Audi S5 be inspected?
Tires on a 2016 Audi S5 should be inspected regularly, not just when tread looks low. Pressure, tread wear, sidewall condition, and any signs of cuts, bulges, or uneven wear deserve routine attention, especially on a performance-oriented car with low-profile radial tires and larger wheel diameters.
A quick visual check before longer drives is a good habit, and a closer inspection should follow any impact with potholes or curbs. Cars that see seasonal use or long storage periods still need periodic tire checks because age, flat spotting, and slow air loss can become issues even when mileage stays low. Consistent inspection helps catch problems before they affect ride quality or clearance.
