The 2014 Audi A6 sits in the modern luxury sport-sedan tradition, blending executive comfort with the sharper road manners buyers expect from a contemporary German four-door. On this generation, tire fitment is closely tied to trim level and wheel package, with four primary radial sizes ranging from 225/55R17 through 255/35R20. That means the real decision is not just brand selection, but confirming the exact wheel diameter already on the car before comparing tires. Available choices also vary in character, from blackwall performance-oriented radials to redline, wide whitewall, and raised white letter treatments in certain sizes. For stock and modified cars alike, appearance, wheel setup, and intended driving use all deserve a careful look before choosing.
Which Tire Size Is Right for The 2014 Audi A6
The 2014 Audi A6 uses four primary tire sizes, and the right one depends on the sub-model and wheel package already on the car. All of them are radial fitments, but they span 17-inch, 18-inch, 19-inch, and 20-inch rims, so confirming wheel diameter is the first step. Once that is settled, the choice shifts to brand, sidewall style, tire series, and whether the car is staying close to its original wheel setup or has been changed.
The 225/55R17 size uses a 225 millimeter section width, a 55-series profile, radial construction, and a 17-inch rim. On the 2014 Audi A6, this size suits buyers looking at the 17-inch fitment and comparing between performance-oriented blackwall radials and more appearance-driven choices such as wide whitewall or redline versions. Available offerings include BFGoodrich g-Force and Silvertown Radial lines. This size is worth considering when the car retains its 17-inch wheel setup and the goal is to balance proper fitment with either a modern performance look or a more distinctive visual presentation.
The 245/45R18 size indicates a 245 millimeter section width, a 45-series profile, radial construction, and fitment on an 18-inch rim. For the 2014 Audi A6, this is one of the key mid-range wheel-package sizes and is offered in blackwall form across several performance-focused series from BFGoodrich and Nitto. Choices include g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This size makes sense for an A6 already equipped with 18-inch wheels where tire selection centers more on brand, series, and rim-width compatibility than on sidewall styling.
The 255/40R19 code denotes a 255 millimeter section width, a 40-series aspect ratio, radial construction, and a 19-inch rim. On the 2014 Audi A6, this size appears on certain wheel-package configurations and opens up both blackwall performance choices and more style-driven treatments such as redline and raised white letter sidewalls. BFGoodrich and Pro-Trac options are available, including g-Force and Street Pro III series. This size deserves careful evaluation when the car already wears 19-inch wheels and the owner wants to compare performance-oriented tread lines against a more custom visual direction.
The 255/35R20 size uses a 255 millimeter section width, a lower 35-series profile, radial construction, and a 20-inch rim. For the 2014 Audi A6, this fitment is tied to 20-inch wheel configurations and offers blackwall selections from BFGoodrich and Nitto along with Pro-Trac Street Pro III versions in raised white letter and redline styles. Because this size runs on the largest rim diameter used here, wheel condition, actual wheel width, and clearance become especially important when comparing options. It is the right path only when the car is already set up for the 20-inch fitment.
Sub-model fitment on the 2014 Audi A6 is not one-size-fits-all, because tire choice changes with trim and wheel option. Checking the exact Premium or Premium Plus configuration matters first, especially when the car may have 17-inch through 20-inch wheels.

2014 Audi A6 Premium
The 2014 Audi A6 Premium uses more than one radial fitment, covering both 17-inch and 18-inch wheel configurations. Tire selection starts with confirming which wheel package is on the car, then comparing the available series and sidewall choices within that exact size.
The 2014 Audi A6 Premium (19 Inch Option) centers the fitment question around the 19-inch wheel package. That makes wheel confirmation straightforward, after which the main comparison becomes blackwall versus custom-style sidewalls and the available radial series in 255/40R19.
The 2014 Audi A6 Premium Plus uses multiple radial sizes tied to different wheel packages, including 18-inch, 19-inch, and 20-inch setups. Selecting tires for this sub-model depends on identifying the wheel diameter first, then narrowing the choice by series, sidewall style, and intended use.
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 2014 Audi A6?
The 2014 Audi A6 uses four primary tire sizes: 225/55R17, 245/45R18, 255/40R19, and 255/35R20. All are radial sizes, and the correct one depends on the sub-model and wheel package rather than a single universal fitment across every A6.
The most important step is confirming the wheel diameter already on the car, since this A6 can use 17-inch, 18-inch, 19-inch, or 20-inch rims. After that, match the exact size to the trim and wheel setup, especially if the car has had aftermarket wheels or a previous owner changed the package.
What size rim does a 2014 Audi A6 use?
A 2014 Audi A6 can use 17-inch, 18-inch, 19-inch, or 20-inch rims, depending on the exact sub-model and wheel option. Those rim diameters correspond to the primary tire sizes 225/55R17, 245/45R18, 255/40R19, and 255/35R20.
Checking the actual wheel on the car matters more than assuming by trim name alone, especially on a used luxury sedan where wheel upgrades are common. Look at the current tire size, confirm the wheel diameter stamped on the wheel if needed, and compare that setup before choosing a replacement tire.
Why does the 2014 Audi A6 have more than one tire size?
The 2014 Audi A6 has more than one tire size because different trims and wheel packages use different rim diameters. Premium models can use 17-inch or 18-inch fitments, the Premium 19 Inch Option uses a 19-inch setup, and Premium Plus models can use 18-inch, 19-inch, or 20-inch sizes.
That means tire selection is really a wheel-package question first. The safest approach is to identify the exact sub-model and confirm what is mounted on the car now, since two A6 sedans from the same model year can need different sizes even before any aftermarket changes are considered.
Choosing the Right Tire
What should I consider when choosing a 2014 Audi A6 tire?
Start with the exact tire size and wheel diameter already used on the car, since the 2014 Audi A6 spans four different radial fitments. After size is confirmed, compare construction details, rim-width suitability, brand, tire series, sidewall style, and any load figures that matter to how the car will be driven.
A daily-driven A6 may lead you toward one group of options, while a style-focused build may put more emphasis on redline, wide whitewall, or raised white letter choices where available. Wheel changes, suspension changes, and the car's intended use should all be settled before choosing among the available products.
What sidewall styles are available for 2014 Audi A6 tires?
Sidewall choices for the 2014 Audi A6 include blackwall across all four primary sizes, with added style options in certain fitments. Depending on size, available treatments include redline, wide whitewall, and RWL, which is a raised white letter sidewall.
The available sidewall style depends on the exact tire size, so appearance choice comes after fitment is confirmed. A 17-inch setup opens different visual options than a 19-inch or 20-inch setup, and buyers focused on presentation should compare the correct size first before narrowing the field by sidewall treatment.
What brands offer tires for the 2014 Audi A6?
Tires for the 2014 Audi A6 are available from BFGoodrich, Nitto, and Pro-Trac, depending on size. BFGoodrich appears across all four fitments, while Nitto is offered in selected 18-inch and 20-inch sizes, and Pro-Trac appears in selected 19-inch and 20-inch applications.
Brand choice should be made within the exact size the car requires, not across the full A6 range. Once the correct fitment is identified, compare the tire series and sidewall treatments each brand offers, since some options are blackwall only while others add a more custom visual presentation.
Restoration & Appearance
Which tire should I choose for a period-style 2014 Audi A6?
A period-style approach for a 2014 Audi A6 starts with keeping the correct wheel diameter and tire size for the trim and wheel package already on the car. From there, the visual direction can stay understated with blackwall performance radials or move toward a more customized presentation in sizes that offer redline, wide whitewall, or raised white letter styling.
Because this is a modern luxury sedan rather than an early collector car, appearance choices are often more about preserving a clean era-appropriate look than chasing exact factory presentation. Buyers who want strict originality should compare the car against window-sticker, build-sheet, or marque-specific reference material before selecting sidewall style.
How does tire construction affect the appearance of a restored 2014 Audi A6?
On the 2014 Audi A6, construction does not create a bias-ply versus radial appearance decision because the vehicle's primary fitments are all radial. The visible differences come more from sidewall treatment, tread character, and overall wheel-and-tire proportion within the correct 17-inch, 18-inch, 19-inch, or 20-inch setup.
That puts the styling emphasis on whether the car is being kept close to a stock executive-sedan look or pushed toward a more customized presentation. Staying with the proper size for the wheel package helps preserve the intended stance, while unusual sidewall treatments can shift the look without changing the basic construction type.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Audi A6?
Yes, modifications can affect tire fitment on a 2014 Audi A6. Aftermarket wheels, altered offsets, suspension changes, or previous wheel-package swaps can change which tire size physically clears the car, even if the original trim could use one of the factory-type 17-inch through 20-inch fitments.
A used A6 should never be sized by model year alone when visible changes have been made. Measure the actual wheel diameter and width, check steering and fender clearance, and compare the existing setup before choosing replacement tires, especially when moving between lower-profile 19-inch and 20-inch combinations.
What should I inspect before driving a 2014 Audi A6 on new tires?
Before driving a 2014 Audi A6 on new tires, inspect the wheel condition, confirm the correct tire size for the wheel package, and make sure each tire is properly inflated and seated. It is also smart to look over the suspension and alignment condition, since uneven wear or poor geometry can quickly affect a new set.
A short clearance check at full steering lock is worthwhile, particularly if the car has non-stock wheels or a lowered stance. After the first few drives, recheck pressure and look for any rubbing, vibration, or unusual wear pattern so fitment concerns are caught early rather than after miles accumulate.
How should tires on a 2014 Audi A6 be maintained?
Tires on a 2014 Audi A6 should be maintained with regular pressure checks, periodic visual inspections, and close attention to tread wear across the full contact patch. Sidewall cuts, bulges, cracking, or repeated air loss deserve prompt attention, especially on cars that may sit for long periods between drives.
Long-term care also includes keeping the car stored away from prolonged heat, direct sunlight, and ozone sources when possible. On an A6 with multiple possible wheel packages, it also helps to document the exact size mounted on the car so future replacement and rotation planning stays consistent.
