The 2012 Audi A6 sits firmly in the modern luxury sport-sedan tradition, blending understated styling with the kind of long-distance composure and all-weather confidence buyers expect from Audi. By this generation, wheel and tire choice had become a visible part of the car’s character, with different trims and wheel packages changing both stance and tire sizing. This Audi A6 uses radial tire fitments in 225/55R17, 245/45R18, or 255/40R19 depending on configuration. Available choices range from performance-oriented blackwall designs to more distinctive redline, raised white letter, and wide whitewall presentations in certain sizes. The key is matching the exact size to the car’s sub-model and wheel diameter before comparing style or driving-purpose differences.
Which Tire Size Is Right for The 2012 Audi A6
The 2012 Audi A6 uses three primary tire sizes, and the correct choice depends first on the exact sub-model and wheel diameter. These are all radial fitments, but they do not share the same rim size, so confirming whether the car is on 17-inch, 18-inch, or 19-inch wheels is the first step before comparing tire style, brand, or performance-oriented product differences.
225/55R17 is a modern metric radial size: 225 identifies the nominal section width in millimeters, 55 is the aspect ratio, R denotes radial construction, and 17 is the wheel diameter in inches. On the 2012 Audi A6, this size suits 17-inch wheel applications and keeps the decision centered on tire character rather than sizing format. Available choices include BFGoodrich performance-focused g-Force lines as well as Silvertown Radial offerings with blackwall, wide whitewall, and redline styling. It is the right size to evaluate when the car carries the corresponding 17-inch setup and the goal is to balance fitment, appearance, and intended road use.
245/45R18 is a metric radial size in which 245 refers to section width in millimeters, 45 indicates the aspect ratio, and the 18 marks the required rim diameter. For the 2012 Audi A6, this size belongs to 18-inch wheel configurations and sits between the narrower 17-inch fitment and the wider 19-inch option. Product choices in this size come from BFGoodrich and Nitto, with blackwall sidewalls across several performance-oriented series. This size deserves attention when confirming an 18-inch wheel package and comparing rim-width compatibility, load figures, and the tire’s overall presentation.
255/40R19 is a modern metric radial size with a 255-millimeter nominal section width, a 40-series profile, and a 19-inch rim requirement. On the 2012 Audi A6, it is the largest of the primary fitments here and belongs to 19-inch wheel applications rather than the smaller-wheel setups. Choices include BFGoodrich g-Force and Phenom series in blackwall form, along with Pro-Trac Street Pro III versions in raised white letter and redline treatments. It is the size to review when the car already has the 19-inch wheel package and the buyer wants to compare performance-style offerings with more distinctive sidewall appearance.
Sub-model fitment matters on the 2012 Audi A6 because tire size changes with trim and wheel package. The Premium and Premium Plus overlap at 245/45R18, but the smaller 225/55R17 and larger 255/40R19 fitments are tied to specific configurations.

2012 Audi A6 Premium
The 2012 Audi A6 Premium uses radial tires in either 225/55R17 or 245/45R18, depending on the wheel setup on the car. That makes wheel-diameter confirmation especially important before comparing sidewall style, brand, or performance-oriented tire series.
The 2012 Audi A6 Premium Plus uses radial tires in 245/45R18 or 255/40R19 form, so the correct choice depends on whether the car carries 18-inch or 19-inch wheels. Tire selection then shifts toward comparing blackwall versus more distinctive sidewall treatments and checking the wheel’s width range.
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?
The 2012 Audi A6 uses three primary radial tire sizes: 225/55R17, 245/45R18, and 255/40R19. The correct size depends on the car’s sub-model and wheel package, with the Premium using 225/55R17 or 245/45R18 and the Premium Plus using 245/45R18 or 255/40R19.
The most important first step is checking the wheel diameter already on the car rather than choosing by appearance alone. A6 sedans with aftermarket wheels or replacement rims may no longer match their original setup, so the actual wheel size and width should be confirmed before selecting a tire.
What size rim does a 2012 Audi A6 use?
A 2012 Audi A6 can use 17-inch, 18-inch, or 19-inch rims depending on the tire size fitted to the car. The 225/55R17 tire uses a 17-inch rim, 245/45R18 uses an 18-inch rim, and 255/40R19 uses a 19-inch rim.
Rim diameter is the non-negotiable starting point because a tire must match the wheel’s diameter exactly. Once that is confirmed, the next checks are wheel width, clearance, and whether the car still carries its original wheels or has been changed to a different package over time.
Do all 2012 Audi A6 sub-models use the same tire size?
No, 2012 Audi A6 sub-models do not all use the same tire size. The Premium overlaps with the Premium Plus at 245/45R18, but the Premium also uses 225/55R17, while the Premium Plus can use 255/40R19.
That overlap means trim name alone is not always enough; wheel diameter still needs to be verified on the car itself. Once the correct size is confirmed, the choice becomes much more straightforward, focusing on available tire series, sidewall style, and compatibility with the actual wheel width.
Choosing the Right Tire
What should I consider when choosing a tire for a 2012 Audi A6?
Start with the correct primary size for the car: 225/55R17, 245/45R18, or 255/40R19. After that, the meaningful differences are radial tire series, wheel-width compatibility, load figures where stated, and whether the goal is a more performance-oriented blackwall tire or a more distinctive appearance treatment.
A 2012 Audi A6 with original wheels may still need verification if the car has changed hands or been modified. Matching the tire to the actual wheel diameter and intended use matters more than choosing by brand name alone, especially when moving between daily road use and a more appearance-driven setup.
What sidewall styles are available for 2012 Audi A6 tires?
Sidewall choices for the 2012 Audi A6 include blackwall across all three primary sizes, along with wider styling variation in certain fitments. The 225/55R17 size is available with wide whitewall and redline treatments, while 255/40R19 also appears in redline and raised white letter form.
That means sidewall style is tied closely to tire size, not just personal preference. A buyer considering a more traditional or more custom presentation should confirm the correct A6 wheel package first, then compare which sidewall treatments are actually offered in that exact size.
What brands offer tires for the 2012 Audi A6?
2012 Audi A6 tire choices here come from BFGoodrich, Nitto, and Pro-Trac, depending on size. BFGoodrich appears across all three fitments, Nitto is offered in 245/45R18, and Pro-Trac appears in 255/40R19 with more appearance-focused sidewall treatments.
Brand comparison is most useful after the correct size is nailed down, because not every brand appears in every fitment. From there, the practical differences usually come down to tire series, sidewall style, and wheel-width suitability rather than assuming one brand serves every A6 configuration equally.
Restoration & Appearance
Which tire should I choose for a period-style 2012 Audi A6?
A period-style approach for a 2012 Audi A6 starts with the correct original-size category for the car’s wheel package, whether that is 225/55R17, 245/45R18, or 255/40R19. From there, the most appearance-sensitive choices are usually within the available radial lines and sidewall treatments rather than changing the size itself.
For a cleaner factory-inspired presentation, many owners stay with blackwall tires in the correct fitment. A more distinctive custom look can come from redline, wide whitewall, or raised white letter options where available, but exact originality should be checked against Audi-specific references if that level of accuracy matters.
How does tire construction affect the appearance of a restored 2012 Audi A6?
On a 2012 Audi A6, construction is straightforward because the primary fitments here are all radial. The bigger appearance difference comes from the tire series and sidewall treatment, since blackwall, redline, wide whitewall, and raised white letter options can change the car’s visual character more than construction type does.
That makes size accuracy and sidewall choice the main appearance decisions for this Audi. Staying with the proper 17-, 18-, or 19-inch fitment preserves the intended stance, while a different sidewall treatment can shift the car toward a subtle stock-style look or a more personalized presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2012 Audi A6?
Yes, modifications can affect tire fitment on a 2012 Audi A6 even when the tire size looks close to stock. Aftermarket wheels, altered offsets, suspension changes, or lowering can all change how a 225/55R17, 245/45R18, or 255/40R19 tire sits relative to the fender, strut, and steering components.
A modified A6 should be checked for actual wheel diameter, wheel width, and clearance at full steering lock before a tire is chosen. That is especially important when moving to 19-inch wheels or wider wheel packages, where small changes in the overall setup can matter more than the tire size alone suggests.
What should I inspect before driving a 2012 Audi A6 on new tires?
Before driving a 2012 Audi A6 on new tires, inspect the wheels for damage, confirm the tire size matches the rim diameter, and check that each tire is seated and inflated properly. It also helps to look over alignment-related wear points, brake clearance, and any signs of rubbing from prior tire or wheel combinations.
A short initial road test can reveal vibration, pull, or clearance issues that are easier to correct early. The car should then be rechecked for air pressure consistency and any fresh contact marks inside the wheelhouse, especially if the A6 has replacement wheels or suspension changes from stock.
How often should tires on a 2012 Audi A6 be inspected?
Tires on a 2012 Audi A6 should be inspected regularly, not just when tread looks low. Monthly pressure checks are a good habit, and a closer inspection for uneven wear, cuts, bulges, sidewall damage, and embedded debris should happen before longer trips or any time the car’s handling feels different.
Luxury sport sedans can mask early tire problems because they remain composed at speed, so visual checks matter. Cars that are driven less often should also be watched for age-related hardening or flat spotting, since time and storage conditions can affect tire condition even when mileage stays relatively low.
