The 2015 Audi A7 Quattro blends sleek fastback styling with the all-weather confidence and high-speed grand touring character that define Audi’s modern luxury sport sedans. It is a vehicle where stance, handling response, and road manners are closely tied to the tire and wheel package under it. This A7 Quattro uses radial fitments in two sizes, 255/40R19 and 265/35R20, so the first step is confirming which wheel diameter is on the car. From there, the choice shifts to sidewall style, tire series, and the overall look you want, especially on cars that balance daily use with enthusiast-minded presentation.
Which Tire Size Is Right for The 2015 Audi A7 Quattro
The 2015 Audi A7 Quattro uses two primary tire sizes, and the difference comes down mainly to wheel diameter rather than separate sub-model-specific fitment. Both sizes are radial, but one fits a 19-inch wheel and the other fits a 20-inch wheel, so confirming the actual wheel package on the car is the first decision. Once that is settled, the real comparison becomes brand, tire series, and sidewall presentation.
Fit(s): Premium Plus, Prestige, TDI Premium Plus, and TDI Prestige
Construction: Radial|Rim: 19 in
255/40R19 is a metric radial size in which 255 identifies nominal section width in millimeters, 40 is the aspect ratio, R denotes radial construction, and 19 is the wheel diameter in inches. On the 2015 Audi A7 Quattro, this size supports the car’s modern road-going fitment while keeping the selection within a 19-inch package. Available choices include BFGoodrich and Pro-Trac options, with blackwall, redline, and raised white letter sidewall treatments across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Street Pro III. This size is the one to evaluate when the car is equipped with 19-inch wheels and you want to compare appearance as well as tire character.

Construction: Radial|Rim: 20 in
265/35R20 is also a metric radial size, with 265 indicating nominal section width in millimeters, 35 identifying the aspect ratio, and 20 showing that it fits a 20-inch wheel. For the 2015 Audi A7 Quattro, this size belongs to the larger wheel package and should be selected only after confirming that the car is actually on 20-inch rims. Product choices include BFGoodrich, Nitto, and Pro-Trac offerings, with blackwall, redline, and raised white letter sidewall options in series such as g-Force Phenom T/A, NT555 G2, and Street Pro III. It is the right size to consider when the car’s current wheel setup and clearance are built around the 20-inch fitment.
Tire fitment stays straightforward across the covered 2015 Audi A7 Quattro sub-models because each one can use the same two radial sizes. The key is not trim level, but verifying whether the car is wearing the 19-inch or 20-inch wheel package before choosing a tire.

2015 Audi A7 Quattro Premium Plus
The 2015 Audi A7 Quattro Premium Plus can use either of the two primary radial sizes, depending on the wheel package on the car. Tire selection starts with confirming 19-inch versus 20-inch wheels, then comparing the available brands, series, and sidewall styles that suit the car’s intended look and use.
The 2015 Audi A7 Quattro Prestige shares the same overall tire-fitment pattern, with both primary radial sizes applying according to wheel diameter. That makes wheel confirmation the important first step, followed by deciding whether a blackwall, redline, or raised white letter presentation fits the car best.
The 2015 Audi A7 Quattro TDI Premium Plus uses the same pair of radial fitment options as the gas-powered versions in this range. The practical decision is checking which wheel diameter is actually on the car and then selecting among the available tire series and sidewall treatments within that size.
The 2015 Audi A7 Quattro TDI Prestige follows the same fitment pattern, so trim does not narrow the tire size by itself. Confirming the installed wheel package is what matters most, especially before choosing between 19-inch and 20-inch tires with different series and appearance 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.

Available 2015 Audi A7 Quattro tires span 255/40R19 and 265/35R20 radial fitments from BFGoodrich, Nitto, and Pro-Trac. The main differences in the product grid are tire series and sidewall style, with blackwall, redline, and raised white letter options depending on size.
These FAQs focus on the two tire sizes used on the 2015 Audi A7 Quattro, how wheel diameter affects fitment, and how to compare radial tire choices by series, sidewall style, appearance, and everyday road-use considerations.
Tire Size & Fitment
What tire size fits a 2015 Audi A7 Quattro?
The 2015 Audi A7 Quattro uses two primary tire sizes: 255/40R19 and 265/35R20. Both are radial fitments, and both are used across the covered A7 Quattro sub-models, including Premium Plus, Prestige, TDI Premium Plus, and TDI Prestige.
The important distinction is wheel diameter. A 255/40R19 belongs on a 19-inch wheel, while a 265/35R20 belongs on a 20-inch wheel. Before choosing a tire, check the actual wheels on the car rather than relying only on trim level, since appearance packages, replacements, or prior wheel changes can affect which size applies.
What size rim does a 2015 Audi A7 Quattro use?
A 2015 Audi A7 Quattro uses either a 19-inch or 20-inch rim, depending on the tire size fitted to the car. The 255/40R19 size uses a 19-inch rim, and the 265/35R20 size uses a 20-inch rim.
That rim diameter difference is the first thing to confirm before comparing products. The tire size and the wheel diameter must match, and it also helps to verify wheel width if the car has aftermarket wheels. Once the wheel setup is confirmed, it becomes much easier to compare series, sidewall treatments, and other tire characteristics within the correct size.
Do all 2015 Audi A7 Quattro sub-models use the same tire size?
The covered 2015 Audi A7 Quattro sub-models all share the same two fitment possibilities: 255/40R19 and 265/35R20. That includes Premium Plus, Prestige, TDI Premium Plus, and TDI Prestige, so the fitment pattern remains consistent across the range.
Even with that shared fitment, the car still needs to be checked for its actual wheel package. A sub-model name alone does not settle whether the car is on 19-inch or 20-inch wheels today. Confirming the current wheel diameter and reading the existing tire size are the most practical steps before selecting a replacement tire.
Choosing the Right Tire
What should I consider when choosing a tire for a 2015 Audi A7 Quattro?
Start with the correct primary size for the wheel on the car: 255/40R19 for a 19-inch rim or 265/35R20 for a 20-inch rim. From there, compare radial tire series, sidewall style, rim-width compatibility where stated, and product characteristics that suit how the A7 Quattro is driven and presented.
Some owners want a straightforward blackwall performance look, while others prefer redline or raised white letter styling for a more customized appearance. It also helps to compare details such as load figures when they are stated and to confirm the car’s current wheel setup if it has ever been changed from stock-style dimensions.
What sidewall styles are available for 2015 Audi A7 Quattro tires?
The available sidewall styles for the 2015 Audi A7 Quattro include blackwall, redline, and RWL, which is raised white letter. Blackwall appears across both sizes, while redline and RWL are available in Pro-Trac Street Pro III options for both 255/40R19 and 265/35R20.
That gives the car owner a real appearance choice beyond basic size and construction, since all of these fitments are radial. A blackwall keeps the look understated and modern, while redline or raised white letters create a more noticeable visual statement. The best choice depends on whether the car is being kept subtle, personalized, or shown with an enthusiast-oriented presentation.
What brands offer tires for the 2015 Audi A7 Quattro?
Tires for the 2015 Audi A7 Quattro are available from BFGoodrich, Pro-Trac, and Nitto, depending on size. BFGoodrich appears in both primary sizes, Pro-Trac offers options in both sizes as well, and Nitto is available in the 265/35R20 fitment.
Brand is only one part of the comparison. The more useful way to shop this fitment is by checking the correct size first, then looking at the specific tire series and sidewall style available from each brand. That approach helps narrow the choice by wheel package, intended appearance, and the overall character you want from the finished setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Audi A7 Quattro?
Yes, modifications can affect tire fitment on a 2015 Audi A7 Quattro even when the tire size itself is correct. Aftermarket wheels, changes in wheel width, offset differences, suspension lowering, and body modifications can all influence how a 255/40R19 or 265/35R20 tire sits and clears the car.
A modified car should be checked for steering clearance, fender clearance, and overall wheel compatibility before a new tire is selected. This matters especially on a low-profile fitment like the A7 Quattro uses, where small changes in wheel setup can have a noticeable effect. Reading the current wheel and tire markings is a smart first step.
What should I inspect before driving a 2015 Audi A7 Quattro on new tires?
Before driving a 2015 Audi A7 Quattro on new tires, inspect the wheel condition, verify the tire size matches the rim diameter, and check that inflation is set correctly for the installation. It is also wise to look over valve stems, confirm even seating at the bead, and make sure there is no visible contact with suspension or body components.
A quick road-use check should include monitoring for vibration, unusual noise, or rubbing during full steering lock and over bumps. Cars that see limited use still benefit from regular visual inspection, since age, storage conditions, and low mileage can hide issues. Keeping an eye on pressure loss and uneven wear will help catch problems early.
How often should tires on a 2015 Audi A7 Quattro be inspected?
Tires on a 2015 Audi A7 Quattro should be inspected regularly, not just when tread appears low. A routine check should include pressure, tread wear, cuts, bulges, cracking, and any signs of uneven wear that could point to alignment, wheel, or suspension concerns.
Cars that are driven occasionally deserve the same attention as daily drivers because age and storage can affect tire condition even with low mileage. It helps to inspect the tires before longer drives and after long periods of sitting. Catching air loss, sidewall damage, or irregular wear early can prevent a small issue from becoming a roadside problem.
