The 2014 Audi S7 blends executive luxury with the sharp, fastback character that made Audi’s modern S cars so appealing to drivers who want real performance without giving up everyday refinement. Its stance and road manners depend heavily on getting the tire size and wheel diameter right, because this model uses two radial fitments: 255/40R19 and 265/35R20. That creates a straightforward but important choice between 19-inch and 20-inch setups, with available tires ranging from blackwall performance radials to raised white letter and redline options. For an S7, the real priority is matching the tire to the wheel already on the car and to the look and driving character you want.
Which Tire Size Is Right for The 2014 Audi S7
The 2014 Audi S7 uses two primary tire sizes, and the first step is confirming whether the car is running 19-inch or 20-inch wheels. Both fitments are radial, and the S7 Base can use either size, so tire selection comes down to matching the wheel diameter already on the car and then deciding between available brands, tire series, and sidewall styles.
A 255/40R19 tire uses a 255 millimeter section width, a 40-series profile, radial construction, and a 19-inch rim. On the 2014 Audi S7, this size supports a modern performance-oriented setup while keeping fitment tied to the 19-inch wheel package. Available choices include BFGoodrich and Pro-Trac products, with blackwall, raised white letter, and redline sidewall treatments depending on the tire series. This size is the right one to evaluate when the car already has 19-inch wheels and you want to compare appearance, performance style, and wheel-width compatibility within that format.
A 265/35R20 tire measures 265 millimeters in nominal section width, uses a 35-series profile, has radial construction, and fits a 20-inch rim. For the 2014 Audi S7, this size corresponds to the larger wheel fitment and slightly wider section width than the 19-inch option. Product choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, redline, and raised white letter sidewall presentations available across different tire series. This size is the one to consider when the car is already equipped with 20-inch wheels and you want to stay within the proper diameter while comparing style and specification differences.
Sub-model fitment is simple here because the 2014 Audi S7 Base is the covered configuration, but it can use either of the two primary tire sizes. Checking the wheel diameter on the car still matters, since the tire choice changes with the 19-inch or 20-inch setup.

Tire Size & Fitment
What tire size fits a 2014 Audi S7?
The 2014 Audi S7 uses two primary tire sizes: 255/40R19 and 265/35R20. Both are radial fitments, and both apply to the S7 Base depending on which wheel package is on the car. The difference is not just tread width and profile, but also the wheel diameter required for each size.
Choosing between them starts with the wheels already installed on the car. A 255/40R19 belongs on a 19-inch wheel, while a 265/35R20 belongs on a 20-inch wheel. Before selecting a tire, confirm the wheel diameter, check the current tire size on the sidewall, and make sure any replacement still suits the vehicle’s wheel width and overall clearance.
What size rim does a 2014 Audi S7 use?
A 2014 Audi S7 uses either a 19-inch or 20-inch rim, depending on which tire size is fitted. The 255/40R19 size uses a 19-inch rim, and the 265/35R20 size uses a 20-inch rim. Both are radial applications for the S7 Base.
That means rim diameter needs to be confirmed before ordering tires, especially if the car has changed hands or has been updated with different wheels. Looking at the current tire sidewall is the quickest check, but it also helps to confirm actual wheel size directly. Once diameter is settled, compare rim-width requirements and tire dimensions so the replacement matches the wheel and the car’s available clearance.
Why does the 2014 Audi S7 have more than one tire size?
The 2014 Audi S7 has more than one tire size because it can be equipped with either a 19-inch or 20-inch wheel setup. That creates two correct primary sizes for the same model: 255/40R19 and 265/35R20. Both are legitimate radial fitments for the S7 Base rather than one universal size for every car.
In practical terms, the car’s current wheel package decides which size should be used. A buyer should not choose only by appearance or tread width without first confirming wheel diameter. If the S7 has aftermarket wheels or previous owner changes, checking the actual wheel and tire combination matters more than assuming one size applies to every example of the model.
Choosing the Right Tire
What should I consider when choosing a tire for a 2014 Audi S7?
Start with the correct primary size for the wheel on the car, since the 2014 Audi S7 uses either 255/40R19 or 265/35R20. Both are radial fitments, so the next comparison points are tire series, sidewall style, rim-width compatibility where stated, and product details such as load figures or weight when those matter to your intended use.
An S7 owner usually ends up balancing driving character and appearance. Some choices stay strictly performance-oriented with blackwall styling, while others add redline or raised white letter presentation for a more customized look. Once the proper size is confirmed, compare the tire’s fit on your wheel, think about how the car is used, and make sure the replacement suits both the setup and the look you want.
What sidewall styles are available for 2014 Audi S7 tires?
The available sidewall styles for 2014 Audi S7 tires include blackwall, redline, and RWL, which is raised white letter. Those choices appear across the two primary sizes, with blackwall options offered in BFGoodrich and Nitto performance tires and redline or RWL options available in Pro-Trac Street Pro III products.
Sidewall style does not change the need for the correct size and rim diameter, but it can significantly change the car’s visual presentation. Blackwall keeps a more understated modern look, while redline and raised white letter create a more custom appearance. Selecting among them comes after confirming whether the S7 is using the 19-inch or 20-inch tire size.
What brands offer tires for the 2014 Audi S7?
Tires for the 2014 Audi S7 are available from BFGoodrich, Pro-Trac, and Nitto. BFGoodrich appears in both the 255/40R19 and 265/35R20 sizes, Pro-Trac also covers both sizes with Street Pro III options, and Nitto is available in the 265/35R20 fitment through the NT555 G2 series.
Brand choice should be weighed alongside the exact size, sidewall treatment, and wheel compatibility rather than treated as a decision by itself. Some buyers may want a straightforward blackwall performance look, while others may prefer redline or raised white letter styling. It helps to narrow the search first by wheel diameter, then compare the brands and tire series available in that exact fitment.
Restoration & Appearance
How does tire construction affect the appearance of a restored 2014 Audi S7?
Tire construction is less of a visual dividing line on a 2014 Audi S7 than it would be on an older collector car, because the S7’s primary fitments are modern radial sizes in both available applications. The more noticeable appearance differences here come from sidewall presentation, with blackwall, redline, and raised white letter options available depending on the size and tire series.
For an owner preserving the car’s original-era character, a clean blackwall usually keeps the overall look closest to the S7’s modern grand touring style. Redline or raised white letter choices push the car toward a more customized presentation. The key is to keep the correct 19-inch or 20-inch fitment first, then decide whether the sidewall should look subtle or more visually assertive.
Does correct tire fitment matter for a 2014 Audi S7 restoration?
Correct tire fitment matters on a 2014 Audi S7 restoration because the car’s proportions, stance, and intended road behavior depend on using the proper size for the wheel package. This model uses either 255/40R19 or 265/35R20, both as radial fitments, so keeping the right combination is part of preserving how the car looks and functions.
A restoration-minded owner should verify what wheel diameter belongs on the specific car before focusing on brand or sidewall details. Once that is settled, the remaining decisions become more appearance-driven, such as choosing blackwall for a restrained look or redline and raised white letter for a custom touch. Exact originality questions are best checked against vehicle-specific reference material and build history.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Audi S7?
Yes, modifications can affect tire fitment on a 2014 Audi S7. Even though the correct primary sizes are 255/40R19 and 265/35R20, aftermarket wheels, suspension changes, lowering, or body alterations can change how much space the tire has and whether the wheel width still suits the tire being considered.
A modified S7 should be checked more carefully than a stock example before replacement tires are chosen. Wheel diameter is only the starting point; wheel width, offset, and available clearance at the fender and suspension also matter. A tire that matches the original size code may still need closer review if the car no longer retains its original wheel and suspension relationship.
What should I inspect before driving a 2014 Audi S7 on new tires?
Before driving a 2014 Audi S7 on new tires, confirm that the size matches the wheel on the car, inspect the wheels for damage, and make sure the tires are seated and inflated correctly. It is also smart to check for suspension wear, alignment issues, or brake and fender clearance concerns that could affect how the new tires behave.
The first miles on fresh tires are a good time to pay attention to vibration, rubbing, pulling, or uneven response. Those symptoms can point to wheel damage, alignment needs, or a fitment mismatch rather than a problem with the tire itself. Rechecking air pressure after installation and watching for any signs of interference helps protect both the tire and the car.
How often should tires on a 2014 Audi S7 be inspected?
Tires on a 2014 Audi S7 should be inspected regularly, especially because performance-oriented cars can be sensitive to uneven wear, pressure loss, or wheel damage. A quick visual check for cuts, sidewall damage, punctures, and tread wear should happen often, and a closer inspection makes sense before longer trips or any spirited seasonal driving.
Collector-minded or lower-mileage examples deserve the same attention even if they are not driven daily. Tires can age, lose pressure, or develop condition issues while the car sits. Looking over the sidewalls, checking inflation, and making sure there is no rubbing or unusual wear pattern helps catch problems early and keeps the S7 ready for safe road use.
