The 2010 Audi A6 sits in the modern sport-luxury sedan category, blending executive-car comfort with the precise road manners buyers expect from an Audi of this era. It is a car where wheel and tire choice strongly affects both stance and driving character, especially when factory-style fitment is spread across more than one wheel diameter. For this A6, primary fitments include 245/45R17, 245/40R18, and 255/35R19, all in radial construction. Available choices range from straightforward blackwall performance radials to redline and raised white letter offerings in select sizes. The key is matching the tire to the exact wheel diameter on the car and choosing a look and tire series that suits how the car will be driven.
Which Tire Size Is Right for The 2010 Audi A6
The 2010 Audi A6 uses three primary tire sizes, and the first step is confirming which wheel diameter is actually on the car: 17-inch, 18-inch, or 19-inch. All three fitments are radial metric sizes, and the single covered sub-model can use any of them. Once wheel diameter is confirmed, the real decision becomes choosing the right tire series, sidewall style, and intended use within that correct size.
The 245/40R18 size identifies a radial tire that is 245 millimeters wide, uses a 40-series aspect ratio, and fits an 18-inch rim. On the 2010 Audi A6, this size supports a lower-profile modern performance presentation while staying within the vehicle's primary radial fitment range. Available choices include blackwall options from BFGoodrich, Nitto, and M&H Racemaster, along with Pro-Trac Street Pro III versions in redline and RWL. This size is worth considering when the car already wears 18-inch wheels and the goal is to balance contemporary road manners with a more personalized sidewall appearance.
The 245/45R17 size is a metric radial with a 245-millimeter section width, a 45-series profile, and fitment for a 17-inch rim. For the 2010 Audi A6, it is one of the primary factory-style sizing formats and gives buyers access to several performance-oriented radial choices. Products in this size include blackwall offerings from BFGoodrich, Nitto, and M&H Racemaster, plus Pro-Trac Street Pro III tires with redline or RWL sidewalls. This size makes sense when the car is equipped with 17-inch wheels and the priority is staying with the proper rim diameter while comparing appearance and tire-series character.
The 255/35R19 size is a metric radial that uses a 255-millimeter section width, a 35-series profile, and a 19-inch rim diameter. Within the 2010 Audi A6 fitment range, it represents the widest and lowest-profile primary size shown here, making wheel confirmation especially important before selection. BFGoodrich offers this size in several blackwall g-Force series options, including all-season and sport-focused variations. It is the correct path to evaluate only when the car already has 19-inch wheels, and buyers should compare rim-width compatibility and overall setup before settling on a specific tire.
Sub-model fitment is straightforward here because the covered 2010 Audi A6 3.2 can use all three primary tire sizes. The important step is not choosing between trims, but confirming which wheel diameter is currently on the car before selecting a tire.

Common 2010 Audi A6 tire questions usually come down to identifying the correct size by wheel diameter, comparing available radial tire lines, and deciding how much appearance matters alongside fitment, maintenance, and road-use checks.
Tire Size & Fitment
What tire size fits a 2010 Audi A6?
The 2010 Audi A6 uses three primary tire sizes: 245/45R17, 245/40R18, and 255/35R19. All three are radial metric fitments, and the covered 2010 Audi A6 3.2 can use any of them depending on the wheel diameter installed on the car.
The main fitment step is confirming whether the car has 17-inch, 18-inch, or 19-inch wheels before choosing a tire. A tire in the wrong rim diameter is not suitable, even if the section width seems close, so the actual wheel setup should be checked first on any A6 that may have had wheel changes over time.
What size rim does a 2010 Audi A6 use?
The 2010 Audi A6 uses 17-inch, 18-inch, or 19-inch rim diameters with its primary tire fitments. Those correspond to 245/45R17 on a 17-inch rim, 245/40R18 on an 18-inch rim, and 255/35R19 on a 19-inch rim.
Rim diameter should be verified before anything else because it determines which of the three primary tire sizes belongs on the car. Looking only at width can lead to the wrong choice, especially on a vehicle like the A6 where multiple wheel packages are possible within the same model year and sub-model coverage.
Why does the 2010 Audi A6 have more than one tire size?
The 2010 Audi A6 has more than one tire size because it can be equipped with different wheel diameters. Its primary fitments span 17-inch, 18-inch, and 19-inch wheels, so the tire size changes with the wheel package rather than with a change from radial to bias-ply construction.
That means the right tire is determined by the actual wheels on the vehicle, not by model name alone. An A6 wearing aftermarket wheels or a different factory wheel package may need a different size than expected, so checking the wheel diameter and the current setup on the car is the safest way to narrow the search.
Choosing the Right Tire
What should I consider when choosing a 2010 Audi A6 tire?
Start with the correct primary size for the wheel diameter on the car: 245/45R17, 245/40R18, or 255/35R19. From there, compare construction details within the radial category, along with brand, tire series, sidewall style, rim-width specification, and whether the tire is intended for general street use or a more specialized purpose.
A blackwall performance radial may suit one A6 owner, while another may want a redline or RWL presentation in the available 17-inch or 18-inch sizes. The best comparison comes from matching the tire to how the car will actually be used and making sure the wheel width and overall setup support that specific tire choice.
What sidewall styles are available for 2010 Audi A6 tires?
Sidewall choices for the 2010 Audi A6 include blackwall across all three primary sizes, with redline and RWL options available in 245/45R17 and 245/40R18. The 255/35R19 offerings shown here are blackwall only.
That gives buyers two different selection paths: a more understated modern look or a more distinctive period-inspired accent on the 17-inch and 18-inch sizes. Sidewall style does not replace the need to match the correct size and rim diameter, so appearance choices should always come after the basic fitment has been confirmed.
What brands offer tires for the 2010 Audi A6?
Tires for the 2010 Audi A6 are available from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, depending on the size. BFGoodrich appears across all three primary fitments, while Nitto, M&H Racemaster, and Pro-Trac are part of the 17-inch and 18-inch selections.
Brand alone should not make the decision. It is more useful to compare which series each brand offers in the exact size needed, whether the sidewall is blackwall, redline, or RWL, and whether the rim-width specification matches the wheel on the car. That approach keeps the choice centered on fitment and intended use.
Restoration & Appearance
Which tire should I choose for a period-style 2010 Audi A6?
A period-style 2010 Audi A6 usually starts with keeping the correct wheel diameter and matching it to one of the primary sizes: 245/45R17, 245/40R18, or 255/35R19. Within those fitments, blackwall tires preserve the most understated modern luxury-sedan look, while some 17-inch and 18-inch options add redline or RWL styling for a more customized presentation.
The right choice depends on whether the goal is to stay visually close to the car's original era or to lean into a more personalized enthusiast look. Appearance should be chosen only after size, rim diameter, and wheel compatibility are confirmed, since the correct visual effect still depends on proper fitment first.
How does tire construction affect the appearance of a restored 2010 Audi A6?
Construction is simpler on the 2010 Audi A6 than on many older collector vehicles because its primary fitments are radial across the board. That keeps the visual decision focused less on bias-ply versus radial shape and more on sidewall treatment, wheel diameter, and the tire series selected within the correct modern metric size.
A blackwall radial generally keeps the car looking closest to a clean original-era sport-luxury setup, while redline or RWL choices create a more noticeable custom effect in available sizes. For an appearance-focused build, matching the right tire to the wheel package matters as much as the sidewall style itself.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Audi A6?
Yes, modifications can affect tire fitment on a 2010 Audi A6. Aftermarket wheels, changes in wheel width, altered offset, suspension lowering, or body and fender changes can all influence whether a primary size such as 245/45R17, 245/40R18, or 255/35R19 still works properly on the car.
A modified A6 should be checked for wheel diameter, wheel width, steering clearance, and body clearance before a new tire is chosen. Even when the size matches one of the accepted primary fitments, the vehicle's actual setup may differ from stock enough that the selection needs a closer look before road use.
What should I inspect before driving a 2010 Audi A6 on new tires?
Before driving a 2010 Audi A6 on new tires, inspect the wheels for the correct diameter and condition, confirm that each tire matches the intended size, and check inflation pressure carefully. It is also smart to look over the suspension and steering for worn components that could affect how the new tires behave on the road.
A short, careful first drive helps confirm there is no rubbing, vibration, or clearance issue at full steering lock or over bumps. Rechecking tire pressure after the first few drives is worthwhile, especially on a car with multiple possible wheel packages where the exact size and wheel combination need to work together.
How often should tires on a 2010 Audi A6 be inspected?
Tires on a 2010 Audi A6 should be inspected regularly, not just when tread looks worn. Checking pressure, tread condition, sidewall condition, and signs of uneven wear at routine intervals helps catch problems early, especially on a sedan where ride quality and handling can change noticeably as tire condition declines.
It also helps to inspect the tires before longer drives and after the car has been parked for extended periods. A close look for cracking, cuts, bulges, or air loss is worthwhile on any low-use vehicle, and the inspection should include the wheel and surrounding suspension area so the tire can perform as intended.
