The 2010 Audi A6 Quattro sits in the later C6 era, blending Audi’s all-weather Quattro character with the poised, high-speed feel buyers expect from a midsize German luxury sport sedan or wagon. Tire choice matters here because wheel and trim combinations change the fitment story. This model uses radial tires in three primary sizes: 245/45R17, 245/40R18, and 255/35R19. Available choices span performance-oriented series, blackwall options, and selected redline or raised white letter styles in the 17-inch and 18-inch sizes. The key is matching the exact sub-model and wheel diameter before comparing appearance, construction details, and intended road use.
Which Tire Size Is Right for The 2010 Audi A6 Quattro
Three primary tire sizes apply to the 2010 Audi A6 Quattro, and they vary by sub-model and wheel diameter rather than by a simple one-size-fits-all setup. The first step is confirming the exact version of the car and whether it is on 17-inch, 18-inch, or 19-inch wheels. Once that is established, the decision shifts to comparing radial tire series, sidewall style, and product specifications within the correct size.
245/40R18 is a metric radial size in which 245 identifies the section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 18 is the rim diameter in inches. On the 2010 Audi A6 Quattro, this size suits configurations that use an 18-inch wheel and keeps the tire profile relatively low for a sport-oriented look and response. Available choices include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, with blackwall, redline, and RWL sidewall treatments depending on the tire. This size is worth evaluating when the car is already equipped with 18-inch wheels and the goal is to compare performance-focused radial options without moving away from the proper wheel diameter.
245/45R17 is a metric radial size that uses a 245-millimeter section width, a 45-series profile, radial construction, and a 17-inch rim. For the 2010 Audi A6 Quattro, it applies to certain sub-models running the smaller wheel package and offers a slightly taller sidewall than the 18-inch alternative while remaining within the modern radial format. Product choices include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, with blackwall, redline, and RWL presentations available in this size. It is the right place to focus when the car wears 17-inch wheels and the buyer wants to compare road-use priorities, sidewall appearance, and tire-series differences within the correct fitment.
Fit(s): 3.0T (19 Inch Option), 4.2, and Avant 3.0T (19 Inch Option)
Construction: Radial|Rim: 19 in
255/35R19 is a metric radial size with a 255-millimeter section width, a 35-series aspect ratio, radial construction, and a 19-inch rim diameter. On the 2010 Audi A6 Quattro, this size belongs to 19-inch wheel applications and brings a wider, lower-profile fitment than the 17-inch and 18-inch sizes. Available products center on BFGoodrich performance-oriented series in blackwall form, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. This size should be considered only after confirming that the car is actually equipped for the 19-inch setup, since wheel diameter is the first fitment checkpoint here.
Sub-model fitment for the 2010 Audi A6 Quattro is not uniform, because tire size changes with both trim and wheel package. Checking the exact sub-model matters first, and any 19-inch option should be confirmed before comparing tires.

2010 Audi A6 Quattro 3.0T
The 2010 Audi A6 Quattro 3.0T uses either 245/45R17 or 245/40R18 radial tires, depending on the wheel setup on the car. That makes wheel-diameter confirmation the key first step before narrowing the choice by tire series, sidewall style, or other product details.
The 2010 Audi A6 Quattro 3.0T with the 19 Inch Option uses 255/35R19 radial tires. Tire selection here starts with preserving that 19-inch fitment and then comparing the available blackwall performance-oriented choices within the proper size.
The 2010 Audi A6 Quattro 4.2 uses either 245/40R18 or 255/35R19 radial tires, so the actual wheel package on the car determines the correct size. Once the wheel diameter is verified, the decision becomes a comparison among the available radial series in that exact fitment.
The 2010 Audi A6 Quattro Avant 3.0T uses either 245/45R17 or 245/40R18 radial tires, depending on the wheels installed. Buyers should confirm the wagon’s current wheel diameter first, then sort through the appropriate tire-series and sidewall options in the matching size.
The 2010 Audi A6 Quattro Avant 3.0T with the 19 Inch Option uses 255/35R19 radial tires. Since this fitment is tied to the 19-inch package, the focus should stay on correct wheel compatibility and on comparing the available blackwall radial offerings in that size.
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.

Owners researching 2010 Audi A6 Quattro tires usually need to sort out the exact size by sub-model and wheel diameter first. The questions below focus on fitment, rim sizing, product selection, appearance options, and practical checks before road use.
Tire Size & Fitment
What tire size fits a 2010 Audi A6 Quattro?
The 2010 Audi A6 Quattro uses three primary radial tire sizes: 245/45R17, 245/40R18, and 255/35R19. The correct size depends on the specific sub-model and wheel package, so there is not one universal tire size across every version of the car.
The most important next step is confirming the actual wheel diameter on the vehicle and matching it to the sub-model configuration. A 17-inch, 18-inch, or 19-inch wheel requires its corresponding tire size, and that should be verified before comparing brands, sidewall styles, or tire series.
What size rim does a 2010 Audi A6 Quattro use?
A 2010 Audi A6 Quattro can use 17-inch, 18-inch, or 19-inch rims, depending on the sub-model and wheel option. Those rim diameters correspond to 245/45R17, 245/40R18, and 255/35R19 radial tire sizes.
Rim diameter should be checked before anything else because the tire must match the wheel exactly. It is also worth confirming wheel width when comparing products, especially if the car has aftermarket wheels, since available tires in these sizes carry different rim-width specifications.
Why does the 2010 Audi A6 Quattro have more than one tire size?
The 2010 Audi A6 Quattro has more than one tire size because fitment changes with sub-model and wheel package. Some versions use 245/45R17, some use 245/40R18, and 19-inch-option cars use 255/35R19.
That means the buyer should identify the exact version of the car and inspect the wheels currently installed before selecting a tire. The sizes are close in overall diameter, but they are built for different rim diameters, so the correct choice depends on the actual wheel setup rather than on the A6 Quattro name alone.
Choosing the Right Tire
What should I consider when choosing a 2010 Audi A6 Quattro tire?
Start with the correct tire size for the car’s exact wheel package: 245/45R17, 245/40R18, or 255/35R19. After that, compare radial tire series, load figures where stated, rim-width compatibility, and the kind of use the car will see, whether that is regular road driving or a more specialized application.
Appearance can also shape the choice, especially in the 17-inch and 18-inch sizes where blackwall, redline, and RWL options are available. A careful match between wheel diameter, wheel width, intended use, and the visual character of the car usually leads to a better decision than choosing by brand name alone.
What sidewall styles are available for 2010 Audi A6 Quattro tires?
Sidewall choices for the 2010 Audi A6 Quattro include blackwall, redline, and RWL depending on tire size. The 245/45R17 and 245/40R18 sizes offer the widest appearance variety, while the 255/35R19 options center on blackwall performance-style tires.
That gives the buyer some freedom to lean toward a cleaner modern look or a more distinctive visual treatment without changing the basic size category. Sidewall style should still be a secondary decision after confirming the correct wheel diameter and selecting a tire whose overall specifications suit the car’s actual setup.
What brands offer tires for the 2010 Audi A6 Quattro?
Tires for the 2010 Audi A6 Quattro are available from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, depending on size. The broadest brand spread appears in the 17-inch and 18-inch fitments, while the 19-inch size is represented by BFGoodrich performance-oriented options.
Brand should be treated as one part of the comparison rather than the whole decision. Tire series, sidewall treatment, rim-width specification, and the car’s actual use all matter, especially when one owner wants a road-oriented radial and another is comparing a more specialized tire type.
Restoration & Appearance
Which tire should I choose for a period-style 2010 Audi A6 Quattro?
A period-style approach for a 2010 Audi A6 Quattro starts with keeping the car in its correct wheel diameter and matching tire size rather than changing the overall fitment theme. From there, the 17-inch and 18-inch sizes offer the most visual variety, including blackwall, redline, and RWL options.
A buyer focused on maintaining the car’s original-era presence should compare sidewall treatment and tire series as carefully as size. Exact originality claims are best checked against Audi-specific reference material or marque documentation, but staying with the proper size family is the strongest starting point for a restoration-minded presentation.
How does tire construction affect the appearance of a restored 2010 Audi A6 Quattro?
Construction is straightforward on the 2010 Audi A6 Quattro because the primary fitments are radial across all three sizes. The visible appearance difference comes less from bias-ply versus radial and more from profile, wheel diameter, and sidewall style choices such as blackwall, redline, or RWL.
That means a restoration-oriented owner should pay close attention to keeping the proper 17-inch, 18-inch, or 19-inch setup for the specific car. The wrong wheel-and-tire combination can change the visual stance quickly, even when the tire itself is still a modern radial in a generally similar size range.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Audi A6 Quattro?
Yes. Modifications such as aftermarket wheels, suspension changes, lowering, or body alterations can affect tire fitment on a 2010 Audi A6 Quattro even when the tire size appears close to stock. Wheel diameter, wheel width, and clearance all influence whether the chosen tire suits the car’s actual setup.
That is especially important on this model because it already uses multiple factory wheel diameters. Any non-stock change should be checked for steering clearance, fender room, and compatibility with the intended tire’s rim-width range before the final selection is made.
What should I inspect before driving a 2010 Audi A6 Quattro on new tires?
Before driving a 2010 Audi A6 Quattro on new tires, inspect wheel condition, confirm the tire size matches the installed rim diameter, and verify that the tires are inflated appropriately for the application. It is also wise to look over suspension and steering components if the car has been sitting or has uneven old-tire wear.
A short road test should include attention to rubbing, vibration, and straight-line behavior. Collector or lower-mile cars deserve an extra look at alignment, brake condition, and any signs of interference inside the wheelhouse, since a correct size still needs a sound vehicle setup to perform properly.
How often should tires on a 2010 Audi A6 Quattro be inspected?
Tires on a 2010 Audi A6 Quattro should be inspected regularly, not just when tread looks low. Pressure, tread wear pattern, sidewall condition, cuts, bulges, and signs of air loss all deserve routine attention, especially on a car that may alternate between long highway use and periods of lighter use.
A practical habit is to check them before longer drives and during normal service intervals. Cars with staggered wheel packages, optional larger wheels, or aftermarket changes benefit from even closer inspection because wear, clearance, and ride-related issues can show up earlier when fitment is more exacting.
