The 2007 Audi A8 Quattro sits in the era when Audi’s flagship sedan balanced understated luxury with all-weather confidence and high-speed touring character. Its aluminum-intensive design and Quattro drivetrain gave it a distinctly modern feel, but tire choice still matters because this exact model was fitted with more than one radial size. The 2007 Audi A8 Quattro uses 255/45R18, 255/40R19, and 275/35R20 tire fitments, all on different rim diameters. Available choices span blackwall, raised white letter, and redline styles across several performance-oriented series. The key step is matching the car’s actual wheel setup before comparing appearance, load capacity, and road-use priorities.
Which Tire Size Is Right for The 2007 Audi A8 Quattro
The 2007 Audi A8 Quattro uses three primary tire sizes, and the first thing to confirm is wheel diameter because each size belongs to a different rim: 18, 19, or 20 inches. All three are radial fitments, and each appears across the covered sub-models. Once the wheel size is confirmed, the decision shifts to profile, sidewall style, tire series, and the kind of driving or presentation you want from the car.
A 255/40R19 tire uses a 255-millimeter nominal section width, a 40-series aspect ratio, radial construction, and a 19-inch rim diameter. On the 2007 Audi A8 Quattro, this is a modern low-profile radial fitment that keeps the focus on precise wheel-size matching and proper profile selection. Available choices include BFGoodrich and Pro-Trac products, with blackwall, raised white letter, and redline sidewall treatments across g-Force and Street Pro III series. This size is worth choosing when the car is already set up on 19-inch wheels and you want to compare appearance and performance-oriented product character within that format.
A 255/45R18 tire carries the same 255-millimeter nominal width as the 19-inch option, but its 45-series profile is built for an 18-inch rim. For the 2007 Audi A8 Quattro, that makes it a distinct wheel-and-tire package rather than a variation of the 19-inch fitment. BFGoodrich, Nitto, and Pro-Trac options are available here, with blackwall, raised white letter, and redline presentations in g-Force, NT555 G2, and Street Pro III series. This size deserves a close look when the car retains 18-inch wheels and you want to balance fitment accuracy with sidewall style and brand preference.
A 275/35R20 tire is wider than the two 255-series options, uses a 35-series profile, and mounts on a 20-inch rim. On the 2007 Audi A8 Quattro, it represents the largest wheel-diameter fitment of the three primary sizes, so wheel confirmation is especially important before making a selection. Product choices include BFGoodrich, Nitto, and Pro-Trac offerings, with blackwall, raised white letter, and redline sidewall treatments in g-Force, NT555 G2, Phenom T/A, and Street Pro III lines. This size makes sense when the car is already equipped with 20-inch wheels and you want to compare available styling and specification differences within that setup.
Tire fitment is straightforward here because the covered 2007 Audi A8 Quattro sub-models share the same three radial size options. Checking the exact sub-model still helps, but the more important step is confirming whether the car is on 18-inch, 19-inch, or 20-inch wheels before choosing a tire.

2007 Audi A8 Quattro Base
The 2007 Audi A8 Quattro Base uses the same three radial fitment paths found across the rest of the lineup, so the real distinction is wheel diameter rather than trim-specific tire sizing. Tire selection comes down to confirming the car’s actual wheel setup and then comparing sidewall style, brand, and series within the matching size.
The 2007 Audi A8 Quattro L 4.2 follows the same overall tire-fitment pattern, with 18-inch, 19-inch, and 20-inch radial options depending on the wheel package on the car. That makes wheel verification the first priority, followed by choosing the product style and series that best suit the sedan’s intended road use and appearance.
The 2007 Audi A8 Quattro L W12 also shares the same three radial tire sizes, so sub-model name alone does not narrow the choice to one fitment. The practical next step is confirming the wheel diameter actually installed, then selecting among the available blackwall, RWL, or redline options in the correct 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.

The most important questions for a 2007 Audi A8 Quattro center on identifying the correct wheel diameter, understanding the three radial tire sizes, comparing sidewall and brand options, and checking fitment carefully on cars with wheel or suspension changes.
Tire Size & Fitment
What tire size fits a 2007 Audi A8 Quattro?
The 2007 Audi A8 Quattro uses three primary tire sizes: 255/45R18, 255/40R19, and 275/35R20. All three are radial fitments, and each size corresponds to a different wheel diameter rather than representing one universal interchangeable setup for every car.
The practical first step is to confirm whether the car is actually riding on 18-inch, 19-inch, or 20-inch wheels. Once that is settled, the right choice becomes much easier, because you can compare the correct size by sidewall style, brand, tire series, and any size-specific rim-width or load-capacity details.
What size rim does a 2007 Audi A8 Quattro use?
The 2007 Audi A8 Quattro appears with three rim diameters tied to its primary tire sizes: 18-inch rims with 255/45R18 tires, 19-inch rims with 255/40R19 tires, and 20-inch rims with 275/35R20 tires. Each tire size is built around its matching wheel diameter.
That means the wheel size on the car must be verified before selecting a tire. Reading the sidewall, measuring the wheel, or confirming the current setup is especially important if the sedan has changed hands or has been updated with different wheels from its original configuration.
Do all 2007 Audi A8 Quattro sub-models use the same tire size?
The covered 2007 Audi A8 Quattro sub-models share the same set of three tire sizes: 255/45R18, 255/40R19, and 275/35R20. That applies to the Base, L 4.2, and L W12 versions, so trim level does not create a separate exclusive tire size in this group.
Even with shared fitment options across the sub-models, the correct purchase still depends on the actual wheels installed on the vehicle. A buyer should match the tire to the current 18-inch, 19-inch, or 20-inch wheel setup rather than assuming every A8 Quattro uses the same size in practice.
Choosing the Right Tire
What should I consider when choosing a tire for a 2007 Audi A8 Quattro?
Start with the correct primary size for the wheel on the car: 255/45R18, 255/40R19, or 275/35R20. From there, compare radial construction details, rim-width compatibility where stated, sidewall style, brand, tire series, and any load-capacity figures that matter to how the sedan will be driven.
A luxury performance sedan like the A8 Quattro benefits from getting the basics right before focusing on appearance. The best comparison process is to verify wheel diameter first, then narrow choices by intended use, whether that means a clean blackwall look, a more distinctive sidewall treatment, or a preferred product line.
What sidewall styles are available for 2007 Audi A8 Quattro tires?
Sidewall choices for the 2007 Audi A8 Quattro include blackwall, RWL, and redline depending on the tire size and product line. Blackwall appears across BFGoodrich and Nitto offerings, while Pro-Trac Street Pro III adds raised white letter and redline alternatives in the applicable sizes.
That gives the car a noticeably different visual character without changing the required tire size itself. Buyers focused on a subtle late-model luxury presentation often lean toward blackwall, while RWL or redline can create a more customized appearance, provided the tire still matches the vehicle’s wheel diameter and intended use.
What brands offer tires for the 2007 Audi A8 Quattro?
Tires for the 2007 Audi A8 Quattro are available from BFGoodrich, Nitto, and Pro-Trac across the three primary sizes. Depending on size, the lineup includes g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III options.
Brand choice should be treated as one part of a larger fitment decision, not the starting point by itself. It helps to compare the correct size first, then look at sidewall style, rim-width guidance, load figures where stated, and the overall look you want from the car once the fitment basics are confirmed.
Restoration & Appearance
Which tire should I choose for a period-style 2007 Audi A8 Quattro?
A period-style 2007 Audi A8 Quattro usually starts with the correct modern radial size for the wheel on the car, then narrows down by visual presentation. Blackwall is the most understated choice, while some sizes also offer RWL or redline versions that give the sedan a more personalized appearance.
Because this is a modern luxury-performance car rather than an early collector-era bias-ply application, appearance choices should stay secondary to correct wheel and tire sizing. A buyer aiming for a more original-looking presentation should verify the current wheel package carefully and use model-specific historical references if exact authenticity matters.
How does tire construction affect the appearance of a restored 2007 Audi A8 Quattro?
Construction is straightforward on the 2007 Audi A8 Quattro because its primary fitments are all radial. That means the visual differences come less from bias-ply-versus-radial shape and more from sidewall treatment, profile, wheel diameter, and the overall stance created by 18-inch, 19-inch, or 20-inch combinations.
A restored or carefully preserved example will usually look most coherent when tire size matches the wheel package cleanly and the sidewall style suits the car’s intended presentation. Blackwall keeps the look restrained, while RWL or redline introduces more visual emphasis without changing the need for correct size and wheel pairing.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Audi A8 Quattro?
Yes. Wheel changes, suspension alterations, lowering, or body modifications can all affect tire fitment on a 2007 Audi A8 Quattro, even when the tire is one of the standard sizes used on this model. Diameter is only the first checkpoint; width, profile, and clearance still need attention.
A car with aftermarket wheels should be checked for wheel width, inner and outer clearance, and steering clearance before a tire is chosen. That becomes especially important when moving among the model’s 18-inch, 19-inch, and 20-inch fitment paths, because a tire that matches the wheel diameter still needs the rest of the setup to work properly.
What should I inspect before driving a 2007 Audi A8 Quattro on new tires?
Before road use, inspect air pressure, wheel condition, valve stems, tread seating, and visible sidewall condition. It also helps to confirm that all four tires match the intended size for the wheel package on the car and that no rubbing or clearance issue appears at full steering lock.
A careful short test drive can reveal vibration, pulling, or contact problems that are easier to correct early. On a performance luxury sedan, alignment condition and suspension wear matter as well, because uneven wear or loose front-end components can shorten tire life and affect the way the car feels on the road.
How often should tires on a 2007 Audi A8 Quattro be inspected?
Tires on a 2007 Audi A8 Quattro should be checked regularly for pressure, tread wear, cuts, cracking, bulges, and signs of air loss. Cars that are driven infrequently still need routine inspection, because age and storage conditions can affect tire condition even when mileage stays low.
A quick visual check before driving and a more thorough inspection at regular service intervals is a practical habit. On a sedan with multiple possible wheel packages, inspection is also a good time to confirm size consistency, watch for uneven wear that may point to alignment issues, and catch problems before a longer highway drive.
