The 2016 Audi A6 sits in the modern sport-luxury sedan category, where understated styling, long-distance comfort, and confident road manners all matter as much as outright specification. Tire choice on this model is closely tied to wheel package, with 245/45R18, 255/40R19, and 255/35R20 radial fitments depending on the exact A6 configuration. That makes this less about old-versus-new construction and more about confirming the correct wheel diameter first, then choosing among available radial tires, sidewall treatments, and performance-oriented series. For an owner balancing original-style proportions, daily use, or a more personalized presentation, the right decision starts with the exact sub-model and wheel setup.
Which Tire Size Is Right for The 2016 Audi A6
The 2016 Audi A6 uses three primary tire sizes, and the correct one depends on sub-model and wheel package. All three are radial fitments, but they span 18-inch, 19-inch, and 20-inch rims, so confirming the actual wheel diameter on the car is the first step before comparing tread style, sidewall appearance, or product specifications.
245/45R18 is a metric radial size in which 245 identifies section width in millimeters, 45 is the aspect ratio, R denotes radial construction, and 18 is the wheel diameter in inches. On the 2016 Audi A6, this size supports a modern touring and sport-sedan fitment on an 18-inch wheel. Available choices include BFGoodrich and Nitto products, mostly in blackwall form, across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, Nitto NT555 G2, and g-Force Phenom T/A. It is the right size to evaluate when the car retains the standard 18-inch wheel package used on covered Premium and Premium Plus versions.
Fit(s): Premium (19 Inch Option) and Premium Plus (19 Inch Option)
Construction: Radial|Rim: 19 in
255/40R19 is a metric radial size with a 255-millimeter section width, a 40-series aspect ratio, radial construction, and a 19-inch rim diameter. For the 2016 Audi A6, this size belongs to 19-inch wheel-option configurations rather than every version of the model. Product choice is broader here, with BFGoodrich and Pro-Trac offerings, including blackwall, raised white letter, and redline sidewall treatments in series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Street Pro III. This is the size to consider when the car has the 19-inch option and the owner wants either a subtle or more visual sidewall presentation.
255/35R20 uses the same 255-millimeter nominal width as the 19-inch option, but pairs it with a lower 35-series profile and a 20-inch wheel diameter. On the 2016 Audi A6, this radial fitment is tied to the 20-inch option rather than the standard wheel setup. BFGoodrich, Nitto, and Pro-Trac options are available, with blackwall, raised white letter, and redline variations across g-Force and Street Pro III lines. This size deserves careful attention because the wheel diameter and lower-profile configuration should match the actual car before selecting by brand, appearance, or load-related specifications.
Sub-model fitment on the 2016 Audi A6 is straightforward once the wheel package is identified, but the tire size does change between standard and optional wheel setups. Checking the exact Premium or Premium Plus configuration matters because the A6 spans three different rim diameters.

2016 Audi A6 Premium
The 2016 Audi A6 Premium uses the 245/45R18 radial size in its standard form. That makes tire selection more about comparing available 18-inch product lines and confirming the car has not been changed to a different wheel package.
The 2016 Audi A6 Premium (19 Inch Option) moves to the 255/40R19 radial fitment. Tire choice here centers on confirming the 19-inch setup, then deciding between blackwall and more appearance-driven sidewall treatments such as RWL or redline.
The 2016 Audi A6 Premium Plus uses 245/45R18 in its standard wheel configuration. For this version, the key step is matching the tire to the existing 18-inch wheels and then comparing the available performance-oriented radial choices within that size.
The 2016 Audi A6 Premium Plus (19 Inch Option) uses the 255/40R19 radial size rather than the standard 18-inch fitment. That means the wheel diameter should be verified first, especially on a used vehicle, before comparing brands, tire series, and sidewall style.
The 2016 Audi A6 Premium Plus (20 Inch Option) uses 255/35R20 radial tires on a 20-inch wheel. This setup calls for careful confirmation of the wheel package and a closer look at sidewall style, tire series, and rim-width compatibility when narrowing the available 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:
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.
Best 2016 Audi A6 Tires for Sale
Available 2016 Audi A6 tires center on the three original-size radial fitments, with BFGoodrich, Nitto, and Pro-Trac options across several g-Force, NT555 G2, and Street Pro III series. Buyers can compare blackwall choices alongside RWL and redline styles on selected 19-inch and 20-inch sizes.
Common 2016 Audi A6 tire questions usually come down to identifying the correct wheel package, understanding the three radial sizes, and comparing available brands, sidewall styles, and maintenance checks before regular road use.
Tire Size & Fitment
What tire size fits a 2016 Audi A6?
A 2016 Audi A6 uses one of three tire sizes: 245/45R18, 255/40R19, or 255/35R20. All are radial fitments, and the correct size depends on the exact sub-model and wheel option rather than the A6 name alone.
The most important step is confirming the wheel diameter currently on the car. A Premium or Premium Plus model may use the standard 18-inch setup, a 19-inch option, or, on the Premium Plus, a 20-inch option, so the tire should match the actual wheel package before comparing brands or sidewall style.
What size rim does a 2016 Audi A6 use?
The 2016 Audi A6 uses 18-inch, 19-inch, or 20-inch rims depending on configuration. Those rim diameters correspond to 245/45R18, 255/40R19, and 255/35R20 tire sizes, with each tire size built around its matching wheel diameter.
Rim diameter is the first fitment checkpoint because a tire must match the wheel exactly. On a used A6, that means checking the wheel itself instead of assuming the car still has its original package, especially if it has changed hands or has already been fitted with aftermarket wheels.
Do all 2016 Audi A6 sub-models use the same tire size?
No. The 2016 Audi A6 spans several sub-model and wheel-package combinations, and they do not all share one tire size. Standard Premium and Premium Plus versions use 245/45R18, while 19-inch option models use 255/40R19 and the Premium Plus 20-inch option uses 255/35R20.
That variation matters because the tire choice follows the actual sub-model and wheel setup, not just the model year and nameplate. Owners should identify the exact trim and confirm the wheel diameter on the car before selecting a tire, particularly when looking at vehicles that may have been altered from stock appearance.
Choosing the Right Tire
What should I consider when choosing a tire for a 2016 Audi A6?
Start with the correct size for the car's wheel package: 245/45R18, 255/40R19, or 255/35R20. From there, compare construction, rim-width compatibility where stated, load-related specifications, tire series, and the type of use the A6 sees, whether that is regular commuting, long highway driving, or a more performance-focused routine.
Appearance can matter too, especially on the 19-inch and 20-inch sizes where sidewall choices extend beyond plain blackwall. A careful comparison should also account for whether the car still has its original wheels and suspension setup, since a tire that matches the size code still needs to suit the actual wheel and overall vehicle configuration.
What sidewall styles are available for 2016 Audi A6 tires?
Sidewall style depends on the tire size. Blackwall options are available across all three A6 sizes, while the 255/40R19 and 255/35R20 fitments also include Pro-Trac Street Pro III tires with RWL and redline sidewall treatments.
That gives the 19-inch and 20-inch wheel packages a wider appearance range than the standard 18-inch setup. Buyers who want a cleaner, understated look may stay with blackwall, while those aiming for a more customized presentation can evaluate raised white letter or redline without changing the underlying tire size required by the wheel.
What brands offer tires for the 2016 Audi A6?
The available 2016 Audi A6 tire brands include BFGoodrich, Nitto, and Pro-Trac. Brand availability varies by size, with BFGoodrich appearing across all three fitments, Nitto offered in 18-inch and 20-inch applications, and Pro-Trac appearing in the 19-inch and 20-inch sizes.
Brand alone should not make the decision. It helps to compare the actual tire series within the correct size, along with sidewall style, rim-width specifications where shown, and load-related details when available, so the final choice matches both the A6 wheel package and the owner's intended use.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Audi A6?
Yes. A 2016 Audi A6 may have the correct nominal tire size for its wheel package, but changes such as aftermarket wheels, altered wheel width, suspension lowering, or body modifications can still affect practical fitment. Clearance at the fender, inner wheelhouse, and steering range should always be considered.
That is especially important on the 19-inch and 20-inch setups, where wheel and tire presentation tends to invite customization. A modified A6 should be checked for actual wheel diameter, wheel width, and available clearance before replacing tires, even when the size stamped on the old tire matches one of the original fitment options.
What should I inspect before driving a 2016 Audi A6 on new tires?
Before regular road use, inspect wheel condition, confirm the tires match the car's 18-inch, 19-inch, or 20-inch wheel package, and check inflation, tread condition, and sidewalls for cuts, bulges, or shipping damage. It also helps to verify that wheel hardware and alignment condition are in good order.
A short, careful test drive is a smart follow-up after installation. Listen for rubbing, watch for vibration, and confirm steering remains smooth through the full range, since the A6 uses multiple wheel-package sizes and any prior wheel or suspension change can influence how a new tire behaves once it is mounted and in service.
How often should tires on a 2016 Audi A6 be inspected?
Tires on a 2016 Audi A6 should be inspected regularly, not just when tread looks worn. Pressure, visible tread wear, sidewall condition, and any signs of uneven contact should be checked routinely, especially on cars that alternate between daily use and long idle periods.
Regular inspection helps catch issues that are not obvious from size alone, including slow air loss, alignment wear, or rubbing from a changed wheel setup. On an A6 with optional 19-inch or 20-inch wheels, staying attentive to tire condition is especially worthwhile because the fitment depends closely on the exact wheel package remaining in place.
