The 2017 Audi A6 sits in the modern sport-luxury sedan class where ride quality, high-speed composure, and crisp road manners all matter as much as curb appeal. In this generation, the A6 balanced understated executive styling with the kind of chassis sophistication that makes wheel and tire selection more than a cosmetic decision. This exact model uses radial fitments in 245/45R18, 255/40R19, and 255/35R20, so the first step is confirming which wheel diameter is on the car. Available choices range from blackwall performance radials to RWL and redline offerings in the larger sizes. That makes this page especially useful for owners comparing everyday road use, appearance, and wheel-specific fitment.
Which Tire Size Is Right for The 2017 Audi A6
The 2017 Audi A6 uses three primary tire sizes, and the right one depends first on the wheel diameter on the car: 18, 19, or 20 inches. Both Premium and Premium Plus models can use these sizes, so the key decision is confirming the actual wheel setup, then choosing the radial tire style, series, and sidewall treatment that best suits how the car is driven and presented.
A 245/45R18 tire uses a 245-millimeter section width, a 45-series aspect ratio, radial construction, and an 18-inch rim. On the 2017 Audi A6, this size represents the 18-inch wheel fitment and keeps the selection firmly in modern radial territory. Available options include BFGoodrich and Nitto products, all in blackwall form, with series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This size is the one to evaluate when the car is equipped with 18-inch wheels and you want to compare brand character, rim-width compatibility, and performance-oriented road manners.
A 255/35R20 tire has a 255-millimeter section width, a lower 35-series profile, radial construction, and fits a 20-inch rim. For the 2017 Audi A6, this is the 20-inch fitment, so wheel diameter confirmation is essential before anything else. Product choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, RWL, and redline sidewall treatments available depending on the series. This size is worth focusing on when the car has 20-inch wheels and appearance is part of the decision, especially if you want to compare a traditional blackwall performance look against more visual sidewall detail.
A 255/40R19 tire combines a 255-millimeter section width with a 40-series profile, radial construction, and a 19-inch rim diameter. On the 2017 Audi A6, this size serves the 19-inch wheel setup and sits between the 18-inch and 20-inch fitments in profile and wheel diameter. Choices include BFGoodrich and Pro-Trac products across blackwall, RWL, and redline presentations, with series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Street Pro III. This size deserves a close look when the car is already on 19-inch wheels and you want a mix of wheel-specific fitment certainty and broader appearance options.
Fitment is straightforward across the covered 2017 Audi A6 sub-models because both Premium and Premium Plus use the same three primary tire sizes. What matters most is confirming whether the car is on 18-inch, 19-inch, or 20-inch wheels before narrowing the tire choice.

2017 Audi A6 Premium
The 2017 Audi A6 Premium can use 245/45R18, 255/40R19, or 255/35R20 radial tires depending on the wheel setup on the car. Tire selection starts with wheel diameter confirmation, then moves to the available brand, series, and sidewall choices within the correct size.
The 2017 Audi A6 Premium Plus follows the same fitment pattern, with 245/45R18, 255/40R19, and 255/35R20 radial sizes used across the model. That makes actual wheel measurement and current vehicle setup more important than trim name alone when choosing the right tire.
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.

Common 2017 Audi A6 tire questions usually come down to size confirmation, wheel diameter, radial fitment, sidewall appearance, and how to choose among the available 18-inch, 19-inch, and 20-inch tire options.
Tire Size & Fitment
What tire size fits a 2017 Audi A6?
The 2017 Audi A6 uses three primary tire sizes: 245/45R18, 255/40R19, and 255/35R20. All three are radial fitments, and both the Premium and Premium Plus sub-models use this same group of sizes rather than one trim-specific size.
The practical step is confirming which wheels are actually on the car before choosing a tire. An A6 with 18-inch wheels needs 245/45R18, while 19-inch and 20-inch wheels use their matching 255-series sizes. If the car has been changed from its original wheel setup, always verify the mounted rim diameter before ordering replacements.
What size rim does a 2017 Audi A6 use?
A 2017 Audi A6 can use 18-inch, 19-inch, or 20-inch rims depending on the tire size on the car. The matching tire sizes are 245/45R18 for 18-inch rims, 255/40R19 for 19-inch rims, and 255/35R20 for 20-inch rims.
Rim diameter is the first thing to confirm because each of these tires is built for a specific wheel size and cannot be mixed across different diameters. It also helps to check wheel width against the tire's acceptable range, especially if the car has aftermarket wheels or a package that changed the original wheel and tire combination.
Do all 2017 Audi A6 sub-models use the same tire size?
The covered 2017 Audi A6 sub-models share the same fitment range rather than one single universal size. Both Premium and Premium Plus use 245/45R18, 255/40R19, and 255/35R20 radial tire sizes depending on the wheel setup installed on the car.
That means the sub-model name alone does not settle the tire decision. The safer approach is to identify the wheel diameter currently on the vehicle, then select within the proper size. This matters even more if the car has changed hands, has optional wheels, or has been updated with a different wheel package since new.
Choosing the Right Tire
What should I consider when choosing a tire for a 2017 Audi A6?
Start with the correct size for the wheel diameter on the car: 245/45R18, 255/40R19, or 255/35R20. From there, compare radial tire series, brand, sidewall style, and wheel-width compatibility so the tire suits both the car's setup and the way it will be driven.
A practical choice often comes down to whether the goal is a straightforward blackwall performance tire or a more distinctive sidewall presentation in the larger sizes. It also helps to compare product details such as rim-width range, load capacity where stated, and the overall character of the series so the A6 stays well matched to its wheels.
What sidewall styles are available for 2017 Audi A6 tires?
Sidewall choices for the 2017 Audi A6 include blackwall across all three sizes, while the 255/35R20 and 255/40R19 sizes also add RWL and redline options. That gives the larger wheel fitments more visual variety than the 245/45R18 size.
For many owners, sidewall style is less about fitment than about presentation. Blackwall keeps a modern, understated look, while raised white letter and redline treatments add a more custom appearance. The key is to keep appearance decisions secondary to the correct wheel diameter and tire size, since sidewall styling does not override basic fitment requirements.
What brands offer tires for the 2017 Audi A6?
The 2017 Audi A6 has tire options from BFGoodrich, Nitto, and Pro-Trac depending on size. BFGoodrich appears across all three primary sizes, Nitto is available in 18-inch and 20-inch fitments, and Pro-Trac is offered in the 19-inch and 20-inch sizes.
Brand choice should be weighed alongside the series and sidewall treatment available in the exact size your wheels require. Some sizes concentrate on blackwall performance-oriented selections, while the larger sizes open the door to more visual sidewall options. Comparing the actual size-specific lineup is more useful than choosing a brand first and hoping it covers every A6 wheel setup.
Restoration & Appearance
Which tire should I choose for a period-style 2017 Audi A6?
A period-style 2017 Audi A6 tire choice usually starts with keeping the correct wheel diameter and matching tire size already on the car. Since this is a modern radial-fitment sedan, the most natural period-style direction is typically a blackwall radial in 245/45R18, 255/40R19, or 255/35R20 rather than a more visibly custom sidewall treatment.
That approach preserves the car's contemporary executive-sport character without introducing a sidewall style that changes the visual tone. Owners who want a stronger custom look can consider RWL or redline in the larger sizes, but a restrained blackwall presentation is usually the cleaner match when originality of overall appearance matters more than making a style statement.
Which sidewall style suits a period-style 2017 Audi A6?
Blackwall is generally the most natural fit for a period-style 2017 Audi A6 because it aligns with the car's modern sport-luxury character and is available across all three primary sizes. RWL and redline are available in the 19-inch and 20-inch fitments, but they create a more customized visual effect.
The right choice depends on whether the goal is a clean factory-inspired presentation or a more individualized look. Sidewall style does not change the required size, so the decision should come after wheel diameter and fitment are confirmed. On a sedan like the A6, subtle appearance choices usually age better than dramatic ones when the car is kept close to stock.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Audi A6?
Yes, modifications can affect tire fitment on a 2017 Audi A6 even when the tire size looks close to one of the standard options. Changes such as aftermarket wheels, altered wheel width, suspension lowering, or body and alignment adjustments can influence clearance, steering travel, and how the tire sits in the wheel opening.
That is why the current setup matters more than assumptions based on trim name alone. Measure wheel diameter, confirm wheel width, and inspect clearance at full steering lock and through suspension movement before changing sizes or replacing worn tires. A modified A6 may need more verification than one still running its original wheel and suspension configuration.
What should I inspect before driving a 2017 Audi A6 on new tires?
Before driving a 2017 Audi A6 on new tires, inspect basic installation and vehicle condition items such as correct size, proper mounting on the right wheel diameter, inflation pressure, valve condition, and visible clearance around the fenders and suspension. It is also wise to look for uneven wear patterns that may point to alignment or suspension issues.
A short visual check after the first miles can be just as useful as the pre-drive inspection. Watch for rubbing, air loss, vibration, or any sign that the tire is not seated and running normally. On a modern sport-luxury sedan, clean fitment and stable road manners depend on both the right tire and the health of the surrounding chassis components.
How often should tires on a 2017 Audi A6 be inspected?
Tires on a 2017 Audi A6 should be inspected regularly, not just when tread looks low. Routine checks should include pressure, tread wear, cuts, bulges, cracking, and any sign of uneven wear that could indicate an alignment, suspension, or wheel issue.
Cars like the A6 can mask tire problems until they become more serious, especially when road manners are normally refined to begin with. A quick visual inspection before longer drives and periodic close checks during normal use help catch issues early. Any recent wheel change, curb impact, or suspension work makes a more careful inspection especially worthwhile.
