The 2012 Audi A6 Quattro sits in the modern luxury-sport sedan space where all-weather confidence, precise road manners, and upscale touring comfort all matter. In this generation, the A6 balanced Audi’s understated executive character with the traction advantage of Quattro, so tire choice plays a real role in preserving the car’s feel. This model uses radial tire fitments, with sizes ranging from 225/55R17 up to 255/35R20 depending on sub-model and wheel package. Available choices also vary by brand, tire series, and sidewall treatment, including blackwall, redline, raised white letter, and wide whitewall options in certain sizes. The key is matching the exact sub-model and wheel diameter before comparing style, profile, and intended road use.
Which Tire Size Is Right for The 2012 Audi A6 Quattro
Four primary tire sizes apply to the 2012 Audi A6 Quattro, and they vary by sub-model and wheel diameter. The first step is confirming the exact sub-model and whether the car is on 17-inch, 18-inch, 19-inch, or 20-inch wheels, because each size is tied to a specific rim diameter. Once that is settled, the decision shifts to tire series, sidewall style, and the kind of road use or appearance you want from a radial tire.
225/55R17 is a metric radial size in which 225 identifies section width in millimeters, 55 is the aspect ratio, R denotes radial construction, and 17 is the rim diameter in inches. On the 2012 Audi A6 Quattro, this size serves buyers looking for the 17-inch wheel fitment rather than a larger-diameter setup. Available choices include blackwall performance-oriented tires as well as Silvertown Radial versions with wide whitewall or redline styling. It is a useful size to evaluate when the car retains its 17-inch wheel package and the goal is either contemporary road manners or a more custom visual presentation.
245/45R18 is a metric radial size that uses a 245-millimeter nominal section width, a 45-series profile, and an 18-inch rim diameter. This size appears across multiple 2012 Audi A6 Quattro sub-models, making it one of the more broadly applicable fitments within the range. Product choices center on blackwall radial tires from BFGoodrich and Nitto, with differences in tire series, rim-width compatibility, load figures where stated, and overall product character. It deserves careful consideration when the car is equipped with 18-inch wheels and you want to compare mainstream sport-touring style options within the correct fitment.
255/40R19 is a metric radial size with a 255-millimeter nominal width, a 40-series profile, and fitment on a 19-inch rim. On the 2012 Audi A6 Quattro, this size moves to a wider, larger-wheel configuration used on certain upper trims rather than every version of the car. Available products include blackwall offerings from BFGoodrich, plus Pro-Trac Street Pro III choices in raised white letter and redline sidewall treatments. This size is worth focusing on when the car already wears 19-inch wheels and the decision is less about fitment discovery than about sidewall appearance and tire-series preference.
255/35R20 is a metric radial size that combines a 255-millimeter nominal section width with a shorter 35-series profile on a 20-inch rim. Within the 2012 Audi A6 Quattro range, it belongs to a larger-wheel setup and should not be treated as interchangeable with the smaller rim-diameter fitments. Product choices include blackwall tires from BFGoodrich and Nitto, along with Pro-Trac Street Pro III options in raised white letter and redline form. It makes sense to evaluate this size when the car is already configured for 20-inch wheels and the buyer wants to compare both modern performance-style tires and more distinctive sidewall treatments.
Tire fitment for the 2012 Audi A6 Quattro depends on the exact sub-model, and some trims share one size while others span multiple wheel packages. Checking whether the car is Premium, Premium Plus, or Prestige is the quickest way to narrow the correct tire size before comparing products.

2012 Audi A6 Quattro Premium
The 2012 Audi A6 Quattro Premium uses either a 225/55R17 or 245/45R18 radial fitment, so wheel diameter needs to be confirmed first. Once that is settled, selection comes down to the available tire series and whether a straightforward blackwall look or a more specialized sidewall treatment matters to the finished appearance.
The 2012 Audi A6 Quattro Premium Plus uses 245/45R18 or 255/40R19 radial tires depending on the wheel setup on the car. That makes this trim a wheel-confirmation fitment decision first, followed by a comparison of blackwall performance-oriented options versus more appearance-driven sidewall choices where available.
The 2012 Audi A6 Quattro Prestige spans three radial sizes, including 245/45R18, 255/40R19, and 255/35R20, so the exact wheel package matters before anything else. After that, the buyer can compare tire series and sidewall presentation, especially on the 19-inch and 20-inch fitments where the visual choices broaden.
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 2012 Audi A6 Quattro?
The 2012 Audi A6 Quattro uses four primary tire sizes: 225/55R17, 245/45R18, 255/40R19, and 255/35R20. All are radial fitments, and the correct size depends on the sub-model and wheel package on the car.
The most important check is the actual wheel diameter, since these sizes are tied to 17-inch, 18-inch, 19-inch, and 20-inch rims. Premium, Premium Plus, and Prestige trims do not all use the same fitments, so confirming the exact sub-model and current wheel setup is the safest starting point before comparing tire series or sidewall style.
What size rim does a 2012 Audi A6 Quattro use?
A 2012 Audi A6 Quattro can use 17-inch, 18-inch, 19-inch, or 20-inch rims, depending on the tire size installed. The four matching tire sizes are 225/55R17, 245/45R18, 255/40R19, and 255/35R20.
Rim diameter is the first fitment point to verify because a tire must match the wheel’s diameter exactly. After that, it helps to compare the tire’s approved rim-width range where stated, especially if the car has aftermarket wheels or a changed wheel package that may differ from the original trim configuration.
Why does the 2012 Audi A6 Quattro have more than one tire size?
The 2012 Audi A6 Quattro has more than one tire size because different sub-models and wheel packages use different rim diameters. Premium can use 17-inch or 18-inch fitments, Premium Plus uses 18-inch or 19-inch sizes, and Prestige can use 18-inch, 19-inch, or 20-inch tires.
That means the right choice is not based on year and model alone. A buyer should verify the trim level, then confirm the actual wheels currently on the car, since replacement wheels or optional packages can change the needed size even within the same 2012 Audi A6 Quattro range.
Choosing the Right Tire
What should I consider when choosing a tire for a 2012 Audi A6 Quattro?
Start with the exact size that matches the car’s wheel setup: 225/55R17, 245/45R18, 255/40R19, or 255/35R20. From there, compare radial tire series, brand, sidewall treatment, and any stated rim-width or load specifications that matter for how the car is used.
A 17-inch Premium setup invites a different comparison than a 20-inch Prestige setup, even though both belong to the same model line. It also helps to think about whether the goal is a clean blackwall touring-performance look or a more customized appearance such as redline, wide whitewall, or raised white letter styling in the sizes that offer them.
What sidewall styles are available for 2012 Audi A6 Quattro tires?
Sidewall choices for the 2012 Audi A6 Quattro include blackwall across all four fitment sizes, with additional specialty styles in certain applications. Depending on size, available options also include redline, raised white letter, and wide whitewall treatments.
Those appearance differences matter most after the correct tire size is established. A buyer looking for a more traditional or custom visual effect may focus on the Silvertown Radial offerings in 225/55R17 or the Pro-Trac Street Pro III choices in 255/40R19 and 255/35R20, while blackwall remains the broadest and most conventional presentation.
What brands offer tires for the 2012 Audi A6 Quattro?
Tires for the 2012 Audi A6 Quattro are available from BFGoodrich, Nitto, and Pro-Trac, depending on the size. BFGoodrich appears across all four fitments, while Nitto and Pro-Trac are present in selected 18-inch, 19-inch, and 20-inch applications.
Brand choice is best treated as one part of a broader fitment decision rather than the first decision itself. Once the correct size is confirmed, compare which brand offers the tire series, sidewall style, and stated rim-width compatibility that best matches the way the car is set up and the look you want from it.
Restoration & Appearance
Which tire should I choose for a period-style 2012 Audi A6 Quattro?
A period-style 2012 Audi A6 Quattro still starts with the correct modern radial size for the car’s trim and wheel package. After that, the most appearance-driven options are the specialty sidewall versions, including Silvertown Radial in 225/55R17 and Pro-Trac Street Pro III in selected 19-inch and 20-inch sizes.
The right choice depends on whether the goal is a subtle executive-sedan look or a more customized presentation. Buyers focused on originality-sensitive restoration should confirm historical references for their exact car, while buyers pursuing a personalized period-inspired style can use sidewall treatment and tire series to shape the finished appearance.
How does tire construction affect the appearance of a restored 2012 Audi A6 Quattro?
On the 2012 Audi A6 Quattro, construction is straightforward because the primary fitments are radial tires throughout the size range. The bigger appearance difference comes less from construction type and more from profile, wheel diameter, and sidewall style such as blackwall, redline, wide whitewall, or raised white letter.
That means a restored or carefully presented A6 usually gains its visual character from choosing the proper size first, then selecting the sidewall presentation that suits the car. A 17-inch fitment with specialty styling creates a different impression than a low-profile 20-inch blackwall setup, even though both remain correct to their wheel diameter.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2012 Audi A6 Quattro?
Yes. Wheel changes, altered suspension height, and aftermarket fitments can all affect tire fitment on a 2012 Audi A6 Quattro, even when the tire size appears close to one of the original options. The biggest variables are wheel diameter, wheel width, and available clearance.
An A6 that still uses its original wheel package is simpler to match than one with custom wheels or a lowered stance. Before replacing tires, check the wheel size actually on the car and make sure there is adequate clearance at full steering lock and through suspension travel, especially on the wider 19-inch and 20-inch fitments.
What should I inspect before driving a 2012 Audi A6 Quattro on new tires?
Before driving a 2012 Audi A6 Quattro on new tires, confirm that all four tires match the wheel diameter on the car and are inflated properly for the application being used. It also makes sense to inspect the wheels themselves for damage, bent lips, or anything that could affect bead seating or balance.
A short road test should include listening for rubbing, vibration, or pull that suggests a setup issue rather than a tire issue. On a car with larger 19-inch or 20-inch fitments, extra attention to steering clearance and suspension condition is worthwhile, because low-profile tires make wheel and alignment problems easier to notice.
How often should tires on a 2012 Audi A6 Quattro be inspected?
Tires on a 2012 Audi A6 Quattro should be inspected regularly, not just when tread looks worn. Air pressure, uneven wear, cuts, bulges, sidewall damage, and signs of vibration-related wear are all worth checking, particularly on a luxury sedan that may see a mix of highway and around-town driving.
Cars that are driven less often still need attention because age and storage conditions can matter as much as mileage. A quick inspection before longer trips, seasonal changes, or extended highway use helps catch problems early, and it is especially useful if the car runs larger-diameter wheels with shorter sidewalls that show impact damage more readily.
