The 2016 Audi S6 sits in the modern super-sedan category, blending executive comfort with the understated speed that has long defined Audi’s S models. It is a car that rewards precision, and tire choice plays a major role in preserving that balance of grip, response, and everyday usability. This S6 uses radial fitments in either 255/35R20 or 255/40R19, with the choice tied first to wheel diameter rather than to a different overall tire height. Available options include blackwall performance tires as well as Pro-Trac Street Pro III choices with raised white letter or redline styling, so appearance can shift along with road manners. The key is matching the tire to the actual wheel setup on the car before comparing brands, series, and sidewall treatment.
Which Tire Size Is Right for The 2016 Audi S6
The 2016 Audi S6 uses two primary tire sizes, and the first step is confirming whether the car is on 19-inch or 20-inch wheels. Both Premium Plus and Prestige models can use either size, so trim alone does not settle the fitment question. Once wheel diameter is confirmed, the decision becomes choosing the right radial tire within that size based on tire series, brand, sidewall style, and the kind of road use or visual presentation you want.
A 255/35R20 tire is a metric radial size with a 255-millimeter section width, a 35-series profile, and fitment for a 20-inch rim. On a 2016 Audi S6, this is one of the two primary radial sizes and suits cars equipped with 20-inch wheels rather than 19-inch wheels. Available choices in this size include BFGoodrich, Nitto, and Pro-Trac, with blackwall, raised white letter, and redline sidewall treatments across several performance-oriented series. This size makes sense when the car already carries the correct 20-inch wheel package and the goal is to compare tire character, appearance, and wheel-width compatibility within that fitment.
A 255/40R19 tire uses the same 255-millimeter nominal width but a 40-series profile on a 19-inch rim. For the 2016 Audi S6, it is the companion primary size for cars fitted with 19-inch wheels, and it preserves the same listed overall diameter as the 20-inch fitment. Product choices include BFGoodrich and Pro-Trac options in blackwall, raised white letter, and redline configurations, giving the buyer room to balance appearance with tire series preference. This is the size to evaluate after confirming the car’s actual wheel diameter, especially if the S6 has been changed from its original wheel setup at some point.
Tire fitment is straightforward across the covered 2016 Audi S6 sub-models because both Premium Plus and Prestige can use the same two radial sizes. What matters most is confirming the wheel diameter on the car, since trim level alone does not narrow the choice to one tire size.

2016 Audi S6 Premium Plus
The 2016 Audi S6 Premium Plus can use either of the two primary radial fitments, so the deciding factor is the wheel setup on the car rather than the trim name itself. Tire selection then comes down to confirming 19-inch versus 20-inch wheels and comparing the available brands, tire series, and sidewall styles within the correct size.
The 2016 Audi S6 Prestige follows the same fitment pattern as the Premium Plus, with both primary radial sizes applying depending on wheel diameter. That means the practical next step is checking the actual wheel size before sorting through blackwall, redline, or raised white letter options in the matching tire 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.

Owners of a 2016 Audi S6 usually need to sort out two things first: whether the car is on 19-inch or 20-inch wheels, and which tire style best matches performance use, appearance preference, and current wheel setup.
Tire Size & Fitment
What tire size fits a 2016 Audi S6?
A 2016 Audi S6 uses one of two primary tire sizes: 255/35R20 or 255/40R19. Both are radial fitments, and both Premium Plus and Prestige sub-models can use either size depending on the wheel package on the car.
The practical step is to confirm the wheel diameter before choosing a tire, since trim level does not narrow it down by itself. A 20-inch wheel calls for 255/35R20, while a 19-inch wheel calls for 255/40R19. Cars with aftermarket wheels, replacement wheel sets, or seasonal wheel swaps should be checked carefully before ordering.
What size rim does a 2016 Audi S6 use?
The 2016 Audi S6 uses either a 19-inch or 20-inch rim, depending on which of its two primary tire sizes is on the car. The 255/40R19 fitment uses a 19-inch rim, and the 255/35R20 fitment uses a 20-inch rim.
Wheel diameter is the first fitment detail to verify because both S6 sub-models can appear with either tire size. It also helps to confirm wheel width when comparing products, since several options in these sizes are intended for a specific width range. Checking the stamping on the wheel or the size on the current tire is usually the fastest way to confirm it.
Do all 2016 Audi S6 sub-models use the same tire size?
The 2016 Audi S6 Premium Plus and Prestige do not narrow the fitment to one single tire size. Both sub-models can use either 255/35R20 or 255/40R19, so the actual wheel diameter on the car determines which size applies.
That means identifying the sub-model is helpful, but it is not the final answer on tire fitment. The more important check is whether the car currently wears 19-inch or 20-inch wheels, especially if it has been altered from its original configuration. Once that is confirmed, the remaining choice is among tire series, sidewall treatment, and brand within the correct size.
Choosing the Right Tire
What should I consider when choosing a 2016 Audi S6 tire?
Start with the correct primary size for the wheel on the car: 255/35R20 for 20-inch rims or 255/40R19 for 19-inch rims. From there, compare radial tire series, brand, sidewall treatment, and any available rim-width or load details that matter to the way the S6 is driven.
A buyer focused on a clean modern presentation may prefer a blackwall tire, while someone wanting a more distinctive look may gravitate toward raised white letter or redline options. It also helps to compare wheel-width compatibility when several products are available in the same size. Matching the tire to the actual wheel setup and intended use will narrow the field quickly.
What sidewall styles are available for 2016 Audi S6 tires?
Tires for the 2016 Audi S6 are available with blackwall, raised white letter, and redline sidewall treatments. Those appearance choices show up across the two primary fitments, giving the car either a more understated modern look or a more visual performance-oriented presentation.
Sidewall style does not replace the need to select the correct size for the wheel diameter, but it can strongly affect the finished look of the car. Blackwall options suit an OEM-style appearance, while raised white letter and redline tires create a more customized statement. Once the size is settled, sidewall treatment becomes one of the easiest ways to tailor the tire choice.
What brands offer tires for the 2016 Audi S6?
The 2016 Audi S6 has tire options from BFGoodrich, Nitto, and Pro-Trac in its primary 255/35R20 and 255/40R19 sizes. Those brands cover several series, including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III.
The useful comparison is not simply brand name, but how each option aligns with the car’s wheel size, desired look, and use. Some choices stay with a blackwall performance appearance, while others add redline or raised white letter styling. Looking at series differences, sidewall treatment, and wheel-width fitment will tell you more than brand alone.
Restoration & Appearance
Which tire should I choose for a period-style 2016 Audi S6?
A period-style approach on a 2016 Audi S6 usually starts with keeping the correct primary size for the wheel diameter already on the car, then choosing a tire that supports the look you want. Blackwall tires maintain the most restrained late-model appearance, while redline or raised white letter options move the car toward a more customized presentation.
Because the S6 is a modern performance sedan rather than a vintage restoration subject, appearance decisions are often more personal than historically fixed. The safest path is to preserve the correct overall fitment first, then use sidewall style and tire series to shape the car’s visual character. Wheel diameter should always be confirmed before treating appearance as the deciding factor.
How does tire construction affect the appearance of a restored 2016 Audi S6?
On a 2016 Audi S6, construction does not create a bias-ply versus radial decision because the primary fitments are radial. The more visible appearance differences come from sidewall treatment, with blackwall giving a cleaner modern look and redline or raised white letter creating a more expressive visual style.
That makes construction a fitment constant and sidewall styling the more meaningful appearance choice. Buyers trying to keep the car visually close to its original era usually lean toward blackwall tires, while custom-minded owners may prefer the Pro-Trac alternatives. Either way, the correct 19-inch or 20-inch fitment remains the foundation for getting the look right.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Audi S6?
Yes, modifications can affect tire fitment on a 2016 Audi S6 even when the tire size itself is one of the correct primary choices. Aftermarket wheels, altered wheel widths, suspension changes, lowering, or body modifications can all change the clearance picture around a 255/35R20 or 255/40R19 tire.
That is why wheel diameter alone is not the only check on a modified car. Wheel width, offset, steering clearance, and fender clearance should all be reviewed before selecting replacement tires. A car that has been changed from stock may still use one of the correct sizes, but the overall combination should be verified before road use.
What should I inspect before driving a 2016 Audi S6 on new tires?
Before driving a 2016 Audi S6 on new tires, inspect the wheel size, tire pressure, valve stems, and the seating of each tire on the rim. It also makes sense to check for any interference at full steering lock and to confirm that the tire size matches the actual 19-inch or 20-inch wheel on the car.
A broader road-use check should include suspension condition, alignment-related wear patterns on the old tires, and any signs that the car has clearance issues from previous wheel or suspension changes. Even a properly sized tire deserves a careful first inspection after installation. Catching rubbing, air loss, or abnormal wear early is much easier than correcting damage later.
How often should tires on a 2016 Audi S6 be inspected?
Tires on a 2016 Audi S6 should be inspected regularly, not just when they look worn out. Pressure, tread condition, cuts, bulges, sidewall damage, and uneven wear deserve attention, especially on a performance sedan that may place greater demand on its tires during everyday driving.
A quick visual check before longer trips is a good habit, and a closer inspection during routine service helps catch issues earlier. Cars that sit for extended periods still need monitoring because age, flat spotting, and gradual air loss can develop even with low mileage. Regular inspection matters just as much as choosing the correct 255/35R20 or 255/40R19 size.
