The 2013 Audi A6 Quattro sits in the modern luxury sport-sedan sweet spot, blending understated executive styling with the all-weather confidence that made Audi’s Quattro name so important in the premium market. Buyers looking at this exact car are usually balancing everyday road manners with the sharper stance and response that come with larger wheel packages. Tire fitment spans four primary radial sizes, from 225/55R17 up to 255/35R20, so the first step is matching the tire to the actual wheel and sub-model configuration on the car. From blackwall performance-oriented radials to redline, raised white letter, and wide whitewall offerings in certain sizes, appearance and driving intent both matter here.
Which Tire Size Is Right for The 2013 Audi A6 Quattro
The 2013 Audi A6 Quattro uses four primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter already on the car. These are all radial fitments, but they span 17-inch, 18-inch, 19-inch, and 20-inch rims, so confirming the wheel size comes first. Once that is settled, the real choice becomes selecting the right tire series, sidewall style, and overall character within the proper size.
In 225/55R17, the 225 is the section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. On the 2013 Audi A6 Quattro, this size delivers a modern radial fitment on a 17-inch rim and is associated with the smaller-wheel setup used on certain versions of the car. Available choices include BFGoodrich options in g-Force and Silvertown Radial lines, with blackwall, wide whitewall, and redline sidewall treatments. This size makes sense for owners who want to confirm a 17-inch wheel package before narrowing the decision to appearance and tire series.
The size 245/45R18 uses a 245-millimeter section width, a 45-series profile, radial construction, and an 18-inch rim diameter. For the 2013 Audi A6 Quattro, it represents one of the main mid-size wheel fitments and appears across multiple sub-models, making it a common starting point for replacement. Product choices include BFGoodrich and Nitto offerings, with series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2, all in blackwall form. This is the size to evaluate when the car is on 18-inch wheels and the goal is choosing among performance-oriented radial options.
A 255/40R19 tire has a 255-millimeter section width, a 40-series profile, radial construction, and fits a 19-inch wheel. On the 2013 Audi A6 Quattro, this size serves as a larger-wheel fitment used across multiple sub-models and brings a wider footprint than the 17-inch and 18-inch packages. Choices in this size range from BFGoodrich performance radials to Pro-Trac Street Pro III options, with blackwall, redline, and RWL sidewall styles available. This size is worth focusing on when the car already wears 19-inch wheels and appearance is as important as the tire series itself.
The code 255/35R20 means a 255-millimeter section width, a lower 35-series profile, radial construction, and a 20-inch wheel diameter. For the 2013 Audi A6 Quattro, this is the largest primary fitment in the group and applies to certain sub-model and wheel-package combinations rather than every car. Available products include BFGoodrich, Nitto, and Pro-Trac offerings, with blackwall, redline, and RWL sidewall choices depending on the tire series. This size deserves careful attention because it belongs with a confirmed 20-inch wheel setup before any comparison of style, load characteristics, or handling-oriented tire lines.
Sub-model fitment on the 2013 Audi A6 Quattro is not completely uniform, because different trims can use different wheel diameters and tire sizes. Identifying whether the car is Premium, Premium Plus, or Prestige helps narrow the correct starting point before comparing tire series or sidewall treatments.

2013 Audi A6 Quattro Premium
The 2013 Audi A6 Quattro Premium uses radial tire fitments that span 17-inch, 18-inch, and 19-inch wheel setups. Tire selection starts with confirming which wheel diameter is actually on the car, then comparing the available blackwall, redline, or wide whitewall options in the matching size where offered.
The 2013 Audi A6 Quattro Premium Plus uses radial fitments tied to 18-inch, 19-inch, and 20-inch wheel configurations. That makes wheel confirmation especially important before choosing a tire series, since the available options change noticeably between the 18-inch package and the larger 19-inch or 20-inch sizes.
The 2013 Audi A6 Quattro Prestige also uses radial tires across 18-inch, 19-inch, and 20-inch wheel setups. Once the actual wheel size is verified, the decision shifts toward the kind of tire presentation and performance character you want, especially in the larger sizes where redline and RWL choices appear.
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.
Best 2013 Audi A6 Quattro Tires for Sale
Available 2013 Audi A6 Quattro tires span 17-inch through 20-inch radial sizes from BFGoodrich, Nitto, and Pro-Trac. Depending on size, buyers can compare blackwall performance series such as g-Force and NT555 G2, along with selected redline, RWL, and wide whitewall options.
These 2013 Audi A6 Quattro tire FAQs focus on the sizes that fit each trim, the wheel diameters involved, and how to sort through radial tire choices, sidewall styles, maintenance checks, and modified-vehicle fitment concerns.
Tire Size & Fitment
What tire size fits a 2013 Audi A6 Quattro?
The 2013 Audi A6 Quattro uses four primary tire sizes: 225/55R17, 245/45R18, 255/40R19, and 255/35R20. All four are radial sizes, and the correct one depends on the sub-model and the wheel diameter installed on the car rather than the model name alone.
The quickest way to narrow the choice is to confirm whether the car has 17-inch, 18-inch, 19-inch, or 20-inch wheels. A Premium can use different sizes than a Premium Plus or Prestige, and many cars may have changed wheels over time, so matching the tire to the actual wheel setup matters more than assuming every A6 Quattro uses the same size.
What size rim does a 2013 Audi A6 Quattro use?
A 2013 Audi A6 Quattro can use 17-inch, 18-inch, 19-inch, or 20-inch rims, depending on the specific tire size and trim configuration. The corresponding tire sizes are 225/55R17, 245/45R18, 255/40R19, and 255/35R20, with each size tied to its own wheel diameter.
Checking rim diameter is the first fitment step because none of these tire sizes cross over from one wheel size to another. Before choosing a replacement tire, verify the wheel itself, then compare the tire’s rim-width compatibility and overall size category so the setup stays appropriate for the car’s clearance and intended use.
Do all 2013 Audi A6 Quattro sub-models use the same tire size?
No. The 2013 Audi A6 Quattro Premium, Premium Plus, and Prestige do not all share one single tire size. Premium uses 17-inch, 18-inch, and 19-inch fitments, while Premium Plus and Prestige use 18-inch, 19-inch, and 20-inch fitments.
That difference is important because it means trim level alone does not always settle the question unless the wheel package is still known and unchanged. Many replacement decisions come down to confirming the actual wheels on the car today, especially if a previous owner changed the factory-style setup or moved to a larger-diameter package.
Choosing the Right Tire
What should I consider when choosing a 2013 Audi A6 Quattro tire?
Start with the correct size for the actual wheel on the car, then compare the tire’s construction, rim-width specification, sidewall style, and product series. On the 2013 Audi A6 Quattro, all primary fitments are radial, but the available choices differ quite a bit between the 17-inch, 18-inch, 19-inch, and 20-inch sizes.
After size confirmation, think about how the car is used and how you want it to look. Some sizes stay focused on blackwall performance radials, while others add redline, RWL, or wide whitewall options. Load capacity, tire weight, and wheel compatibility can also help separate two similar-looking choices when comparing products in the same size.
What sidewall styles are available for 2013 Audi A6 Quattro tires?
Sidewall styles for the 2013 Audi A6 Quattro include blackwall across all four primary sizes, with additional redline, RWL, and wide whitewall treatments available in certain sizes. The 17-inch size adds wide whitewall and redline options, while the 19-inch and 20-inch sizes include redline and RWL choices alongside blackwalls.
That makes sidewall style part of the buying decision rather than a minor detail. A blackwall keeps the presentation modern and straightforward, while redline, RWL, or wide whitewall options create a more customized appearance. The main thing is to choose the sidewall treatment only after confirming the correct tire size for the wheel and trim.
What brands offer tires for the 2013 Audi A6 Quattro?
Tires for the 2013 Audi A6 Quattro are available from BFGoodrich, Nitto, and Pro-Trac, depending on the size. BFGoodrich covers all four sizes, Nitto appears in the 18-inch and 20-inch fitments, and Pro-Trac is offered in the 19-inch and 20-inch sizes.
Brand comparison is most useful once the exact size is settled, because not every brand appears in every fitment. From there, look at tire series, sidewall treatment, rim-width range, and load figures where shown. That approach gives a more useful comparison than choosing by brand name alone, especially on a car with multiple possible wheel packages.
Restoration & Appearance
Which tire should I choose for a period-style 2013 Audi A6 Quattro?
A period-style approach on a 2013 Audi A6 Quattro usually starts with keeping the correct wheel diameter and tire size already associated with the car’s trim and setup. From there, the decision becomes whether to stay with a straightforward blackwall performance radial or choose a more distinctive presentation such as redline, RWL, or wide whitewall where available.
Because this is a modern luxury sedan rather than an early collector-era car, appearance choices often lean more toward personal taste than strict restoration standards. The cleanest result usually comes from matching the tire’s sidewall style to the wheel design and overall look of the car, while avoiding a size change that alters the intended fitment balance.
How does tire construction affect the appearance of a restored 2013 Audi A6 Quattro?
On the 2013 Audi A6 Quattro, construction is straightforward because the primary fitments are radial across all supported sizes. That means the visual differences come less from bias-ply versus radial concerns and more from profile, wheel diameter, and sidewall treatment within the correct radial size.
A 17-inch setup with a taller sidewall presents the car differently than a 19-inch or 20-inch package with a shorter profile, even when overall tire diameter stays close. Sidewall styling matters too, since blackwall, redline, RWL, and wide whitewall options can change the car’s personality without moving away from the proper basic size format.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Audi A6 Quattro?
Yes. Modifications can affect tire fitment on a 2013 Audi A6 Quattro, especially if the car has aftermarket wheels, a different wheel offset, lowered suspension, or body and brake changes. Since this model already uses four distinct tire sizes across four rim diameters, even small setup changes can alter the fitment picture.
A modified car should be checked for wheel diameter, wheel width, steering clearance, and fender clearance before settling on a replacement tire. It also helps to confirm that the tire size currently on the car matches the wheel it is mounted on, rather than assuming the existing setup is automatically the correct reference point.
What should I inspect before driving a 2013 Audi A6 Quattro on new tires?
Before driving a 2013 Audi A6 Quattro on new tires, inspect the wheel size, confirm the tire size matches the rim diameter, and look over the suspension and steering components for wear that could affect alignment or clearance. Tire pressure should also be set correctly, and each tire should be checked for proper seating and visible damage.
A short initial drive followed by a second inspection is a smart habit, especially on cars with larger 19-inch or 20-inch wheel packages. Recheck pressure, look for any rubbing marks, and pay attention to pull, vibration, or unusual noise. Those early signs can reveal a fitment or setup issue before it becomes a more expensive problem.
How often should tires on a 2013 Audi A6 Quattro be inspected?
Tires on a 2013 Audi A6 Quattro should be inspected regularly, not just at replacement time. Check them for uneven tread wear, cuts, bulges, cracking, and air loss, and look more closely if the car has recently had wheel changes, alignment work, suspension service, or long periods of storage.
Frequent inspection matters because this car can run several different wheel-and-tire combinations, and each one places a little more importance on catching clearance or wear problems early. A quick visual check before longer drives, combined with routine pressure monitoring, helps preserve ride quality and can alert you to issues before they affect handling or tire life.
