The 2013 Audi S7 blends executive luxury with the sleek fastback shape and high-output character that define Audi’s modern S models. It is the kind of car that asks for tire fitment that supports both its visual stance and its road manners, especially because wheel diameter changes the tire size choice. This model uses radial tires in either 255/40R19 or 265/35R20, both tied to specific 19-inch or 20-inch wheel setups. Available choices include blackwall, redline, and raised white letter styles across several performance-oriented series. The key is confirming which wheel package is on the car before comparing brand, sidewall, and tread-family options.
Which Tire Size Is Right for The 2013 Audi S7
The 2013 Audi S7 uses two primary tire sizes, and the first thing to confirm is wheel diameter. A 19-inch wheel uses 255/40R19, while a 20-inch wheel uses 265/35R20, so the tire decision starts with the actual wheel package on the car. Once that is settled, the choice becomes comparing radial tire options by brand, sidewall style, tire series, and wheel-width compatibility.
255/40R19 is a metric radial size in which 255 identifies the nominal section width in millimeters, 40 is the aspect ratio, and 19 is the rim diameter in inches. On the 2013 Audi S7, this size belongs with the 19-inch wheel setup and keeps the fitment in a modern radial format suited to the car’s performance-luxury character. Available choices include BFGoodrich and Pro-Trac options, with blackwall, redline, and raised white letter presentations depending on the tire series. This size is the right place to start when the car is equipped with 19-inch wheels and the goal is to compare appearance and performance-oriented tire families within that setup.
265/35R20 is a metric radial size where 265 indicates nominal section width in millimeters, 35 is the aspect ratio, and 20 identifies the wheel diameter in inches. For the 2013 Audi S7, this size corresponds to the 20-inch wheel arrangement and reflects a lower-profile radial fitment than the 19-inch option. Product choices include Nitto, BFGoodrich, and Pro-Trac, with blackwall, redline, and raised white letter sidewall treatments represented in the available lineup. This size deserves a close look when the car already carries 20-inch wheels and the owner wants to balance wheel-package accuracy with brand and sidewall preference.
Sub-model fitment is straightforward here because the 2013 Audi S7 Base uses the same two tire-size paths found on the overall model. The important step is not sorting through multiple trims, but confirming whether the car has the 19-inch or 20-inch wheel setup before choosing tires.

2013 Audi S7 Base
The 2013 Audi S7 Base can use either of the model’s radial tire sizes, depending on which wheel diameter is on the car. That means tire selection starts with the actual 19-inch or 20-inch wheel setup, then moves to comparing available brands, sidewall styles, and tire series within the matching 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.

Tire Size & Fitment
What tire size fits a 2013 Audi S7?
The 2013 Audi S7 uses two primary tire sizes: 255/40R19 and 265/35R20. Both are radial sizes, and each one matches a different wheel diameter, so the correct choice depends on whether the car is equipped with 19-inch or 20-inch wheels.
The practical step is to confirm the wheel diameter on the car before comparing tires. A 255/40R19 belongs with a 19-inch wheel, while a 265/35R20 belongs with a 20-inch wheel. If the car has been changed from its original wheel package, check the actual wheel size and available clearance rather than choosing only by model name.
What size rim does a 2013 Audi S7 use?
A 2013 Audi S7 can use either a 19-inch or 20-inch rim, depending on the wheel setup on the car. The 255/40R19 tire fits the 19-inch arrangement, and the 265/35R20 tire fits the 20-inch arrangement.
Wheel diameter is the first fitment checkpoint because it determines which tire size belongs on the car. Beyond diameter, it is also wise to compare wheel width against the tire’s recommended rim-width range when that specification is available. That becomes especially important if the S7 has aftermarket wheels instead of the original wheel package.
Do all 2013 Audi S7 sub-models use the same tire size?
The covered 2013 Audi S7 sub-model is the Base, and it uses the same two tire-size paths as the overall model: 255/40R19 and 265/35R20. The variation is tied to wheel diameter rather than to a different trim-specific tire construction.
That makes sub-model identification less important than wheel confirmation. A Base model with 19-inch wheels needs the 255/40R19 size, while a Base model with 20-inch wheels needs the 265/35R20 size. Looking at the wheel itself or the existing sidewall marking is the quickest way to avoid ordering the wrong size.
Choosing the Right Tire
What should I consider when choosing a 2013 Audi S7 tire?
Start with the correct size for the wheel package: 255/40R19 for 19-inch wheels or 265/35R20 for 20-inch wheels. From there, compare the available radial tire choices by brand, tire series, sidewall treatment, and any wheel-width or load-capacity details attached to the specific tire.
The right pick depends on how the car is used and how the owner wants it to look. Some options keep a more understated blackwall presentation, while others add redline or raised white letter styling. On a modified S7, tire choice should also be checked against the current wheel width, suspension height, and available fender and steering clearance.
What sidewall styles are available for 2013 Audi S7 tires?
2013 Audi S7 tires are available with blackwall, redline, and raised white letter sidewall treatments, depending on the size and tire series selected. Blackwall appears across several options, while redline and RWL choices are available in Pro-Trac Street Pro III offerings.
Sidewall style is mostly an appearance decision once the correct size and wheel diameter are established. A blackwall suits a more subtle modern presentation, while redline or raised white letter tires create a more custom look. Since sidewall treatment varies by series and size, it helps to narrow the tire size first and then compare the available visual styles.
What brands offer tires for the 2013 Audi S7?
BFGoodrich, Pro-Trac, and Nitto offer tires for the 2013 Audi S7 across its two radial sizes. BFGoodrich appears in both 19-inch and 20-inch fitments, Pro-Trac offers style-focused options in both sizes, and Nitto is present in the 265/35R20 fitment.
Brand choice should be considered alongside the exact size and the type of presentation you want from the tire. Some series are only offered in blackwall form, while others include redline or raised white letter styling. It also helps to compare wheel-width guidance and any stated load figures when narrowing the final selection.
Restoration & Appearance
Which tire should I choose for a period-style 2013 Audi S7?
A period-style approach for a 2013 Audi S7 starts with keeping the correct wheel-diameter fitment, either 255/40R19 or 265/35R20, and then selecting a tire that matches the look you want. Blackwall tires usually preserve the most understated, contemporary appearance for a car from this era.
Appearance can shift noticeably with sidewall treatment even when the size stays the same. Redline and raised white letter options introduce a more custom visual character, while blackwalls remain closer to a subtle factory-inspired presentation. Owners focused on exact as-delivered appearance should compare against original window-sticker, dealer, or marque-specific reference material.
How does tire construction affect the appearance of a restored 2013 Audi S7?
Construction is straightforward on the 2013 Audi S7 because the primary fitments are radial tires in both available sizes. That means the visual difference usually comes less from bias-ply versus radial concerns and more from profile, wheel diameter, and sidewall style within the correct radial size.
On a modern performance-luxury car like the S7, the wrong diameter or an overly aggressive sidewall treatment can change the overall presentation quickly. Keeping the proper 19-inch or 20-inch tire size is the foundation, then choosing between blackwall, redline, or raised white letter styling based on whether the goal is restrained, customized, or show-oriented appearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Audi S7?
Yes. Wheel changes, suspension lowering, spacer use, or other modifications can affect tire fitment on a 2013 Audi S7 even when the tire size looks close to stock. The car’s two primary sizes already depend on wheel diameter, so any change to the wheel package can alter clearance and compatibility.
A modified S7 should be checked for wheel width, offset, steering clearance, and fender clearance before finalizing tires. That matters most when moving between 19-inch and 20-inch setups or using aftermarket wheels. Looking at the actual wheel and tire markings on the car is more reliable than assuming every S7 still carries its original configuration.
What should I inspect before driving a 2013 Audi S7 on new tires?
Before driving a 2013 Audi S7 on new tires, inspect basic installation and condition items such as air pressure, bead seating, valve stems, tread and sidewall condition, and any sign of interference at full steering lock. It also helps to confirm that the size matches the wheel diameter on the car.
A short, careful road test is a smart follow-up after installation. Listen for rubbing, feel for vibration, and recheck pressure after the tires have settled in. On a car that has seen wheel swaps or suspension changes, extra attention to inner-fender and suspension clearance can prevent problems that do not show up while the car is parked.
How often should tires on a 2013 Audi S7 be inspected?
Tires on a 2013 Audi S7 should be inspected regularly, not just when tread looks worn. Pressure, visible cracking, uneven wear, punctures, bulges, and signs of air loss are all worth checking, especially on a car that may see seasonal or lower-mileage use.
Routine inspection matters because performance-oriented low-profile tires can hide problems until they affect ride quality or clearance. A quick visual check before longer drives and periodic close inspection in the garage help catch wear or aging early. Any time the car sits for extended periods, tire pressure and general condition deserve attention before returning it to road use.
