The 1999 Audi A8 Quattro represents Audi’s flagship full-size luxury sedan from an era when aluminum construction, all-wheel-drive confidence, and understated European styling helped it stand apart from more conventional executive cars. Buyers looking at one today are often balancing originality, road manners, and visual presentation rather than simply replacing worn rubber. This A8 Quattro uses radial tires in two primary sizes, 225/55R17 and 225/60R16, depending on wheel fitment. Available choices range from performance-oriented blackwall radials to Silvertown Radials with redline or whitewall treatments. The key is confirming which wheel diameter is on the car before choosing the tire style that best suits its use and appearance.
Which Tire Size Is Right for The 1999 Audi A8 Quattro
The 1999 Audi A8 Quattro uses two primary tire sizes, both in metric radial construction, and the correct choice depends first on wheel diameter. One setup uses a 17-inch rim and the other uses a 16-inch rim, so identifying the actual wheels on the car matters before comparing brands, sidewall styles, or series.
225/55R17 is a metric radial size in which 225 identifies the nominal section width in millimeters, 55 is the aspect ratio, and 17 is the wheel diameter in inches. On the 1999 Audi A8 Quattro, this size suits a 17-inch wheel and keeps the tire choice in a fully modern radial format. Available options include BFGoodrich performance-oriented blackwall selections as well as Silvertown Radial versions with wide whitewall and redline styling. This size is the right place to start for an A8 Quattro already fitted with 17-inch wheels and for owners who want to compare road-focused and appearance-driven choices within the same fitment.
225/60R16 is also a metric radial size, with the same 225-millimeter nominal section width but a 60-series profile on a 16-inch wheel. For the 1999 Audi A8 Quattro, it represents the 16-inch wheel fitment and should be matched to the wheel currently on the car rather than chosen by appearance alone. Product choices include Goodyear, BFGoodrich, and Travelstar offerings, with sidewall treatments such as raised yellow letter, redline, pin white stripe, wide whitewall, and narrow whitewall. This size is worth evaluating carefully when maintaining a 16-inch setup or when the car’s visual character matters as much as everyday road use.
Fitment is straightforward here because the covered sub-model shares the same two radial tire-size options. The important step is not choosing between trims, but confirming whether the car is on 16-inch or 17-inch wheels before selecting a tire.

Tire Size & Fitment
What tire size fits a 1999 Audi A8 Quattro?
The 1999 Audi A8 Quattro uses two primary tire sizes: 225/55R17 and 225/60R16. Both are radial metric sizes, and both apply to the A8 Quattro Base depending on the wheel setup installed on the car.
The key difference is wheel diameter, not vehicle trim. A 17-inch wheel calls for 225/55R17, while a 16-inch wheel calls for 225/60R16. Before choosing a tire, check the actual wheel size on the vehicle, especially if it has changed hands over the years or has been fitted with different factory-style or aftermarket wheels.
What size rim does a 1999 Audi A8 Quattro use?
A 1999 Audi A8 Quattro can use either a 17-inch rim or a 16-inch rim. The 225/55R17 tire size matches the 17-inch fitment, and the 225/60R16 tire size matches the 16-inch fitment.
That means the wheel diameter has to be confirmed before a tire is selected. Looking only at the car model is not enough, because both tire sizes belong to the same year and model. It also helps to inspect wheel width and overall condition, particularly if the car has aftermarket wheels or if the original setup has been changed.
Why does the 1999 Audi A8 Quattro have more than one tire size?
The 1999 Audi A8 Quattro has more than one tire size because it can be fitted with two different wheel diameters. One setup uses 225/60R16 on a 16-inch rim, and the other uses 225/55R17 on a 17-inch rim.
Those two sizes are close in overall tire proportions, but they are not chosen interchangeably without regard to the wheel. The correct approach is to match the tire to the rim diameter already on the car. Once that is settled, the decision becomes more about sidewall style, brand, and the type of driving or appearance the owner wants.
Choosing the Right Tire
What should I consider when choosing a tire for a 1999 Audi A8 Quattro?
Start by matching the tire to the wheel diameter on the car, since the 1999 Audi A8 Quattro uses either 225/55R17 or 225/60R16. Both are radial fitments, so the next considerations are tire series, sidewall style, brand, and the intended look and use of the vehicle.
Some choices lean toward a modern blackwall presentation, while others offer redline, whitewall, or stripe styling that changes the car’s visual character. Rim-width compatibility is also worth comparing, especially if the wheels are not original to the car. A careful selection balances fitment, appearance, and the kind of road use the sedan will actually see.
What sidewall styles are available for 1999 Audi A8 Quattro tires?
Sidewall choices for the 1999 Audi A8 Quattro include blackwall, redline, wide whitewall, pin-white-stripe, narrow whitewall, and raised-yellow-letter depending on the tire size and series selected. Those styles are spread across the 225/55R17 and 225/60R16 fitments rather than concentrated in only one type of tire.
That variety gives the car very different visual personalities. A blackwall tire keeps a more contemporary and understated appearance, while whitewall, stripe, or redline treatments create a stronger period-inspired look. The practical step is to choose the correct size first, then narrow the field by sidewall treatment that suits the A8’s presentation and intended use.
What brands offer tires for the 1999 Audi A8 Quattro?
Tires for the 1999 Audi A8 Quattro are available from BFGoodrich, Goodyear, and Travelstar across the two primary sizes. BFGoodrich appears in both fitments, while Goodyear and Travelstar are represented in the 225/60R16 size.
Brand choice should be considered alongside tire series, sidewall style, and wheel compatibility rather than treated as a standalone decision. Some offerings are performance-oriented blackwalls, while others are styled radials with redline or whitewall treatments. Comparing the exact tire within the correct size usually matters more than choosing a name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1999 Audi A8 Quattro?
A period-style 1999 Audi A8 Quattro tire choice starts with the correct wheel diameter, since the car uses either 225/55R17 or 225/60R16. Once that is confirmed, styled radial options such as Silvertown Radial redline or whitewall versions offer a more restoration-oriented or era-conscious presentation than a plain blackwall performance tire.
The right visual choice depends on how original, subtle, or expressive the car is meant to look. A sedan preserved in near-stock form may call for a restrained sidewall treatment, while a more personalized car can support a stronger stripe or whitewall look. Exact originality questions are best checked against marque-specific references and surviving period examples.
How does tire construction affect the appearance of a restored 1999 Audi A8 Quattro?
On the 1999 Audi A8 Quattro, construction does not create a bias-ply versus radial decision because the primary fitments are radial. The appearance difference comes more from sidewall treatment and tire series than from construction type, especially between blackwall, redline, whitewall, and stripe-style options.
That makes the visual decision more nuanced than it would be on an earlier collector car. A blackwall tire can keep the A8 looking more modern and understated, while whitewall or redline versions shift the car toward a more distinctive custom or nostalgic presentation. The final choice should still respect the wheel diameter and the physical setup already on the car.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1999 Audi A8 Quattro?
Yes, modifications can affect tire fitment on a 1999 Audi A8 Quattro. Changes such as aftermarket wheels, altered wheel width, suspension adjustments, or ride-height changes can influence which of the two primary sizes works properly and whether the tire clears the body and suspension through full steering travel.
That is especially important on a car that may already differ from its original wheel package. Confirm the actual rim diameter first, then inspect wheel width and clearance at the fender, inner wheelhouse, and suspension points. Even when a tire is correct for the model range, the car’s present setup should be checked before installation and regular road use.
What should I inspect before driving a 1999 Audi A8 Quattro on new tires?
Before driving a 1999 Audi A8 Quattro on new tires, inspect the wheels for correct diameter and condition, verify the tire size matches the wheel, and check that the tires seat properly and hold air consistently. It is also smart to look at valve stems, alignment condition, and visible suspension wear.
A short visual check can prevent fitment surprises after installation. Turn the steering from lock to lock and look for any sign of rubbing, especially if the car has non-original wheels. Proper inflation, even tread contact, and a clean clearance check matter just as much as choosing the correct 225/55R17 or 225/60R16 size in the first place.
How often should tires on a 1999 Audi A8 Quattro be inspected?
Tires on a 1999 Audi A8 Quattro should be inspected regularly, even if the car is driven infrequently. A quick check before routine use and a more thorough inspection before longer drives helps catch uneven wear, air loss, sidewall cracking, cuts, bulges, or other age-related issues that may not be obvious at a glance.
Low-mileage luxury and collector cars can age their tires out before they wear them out. It helps to monitor inflation pressure, watch for vibration or pull once underway, and inspect tread and sidewalls after storage periods. Keeping the car away from prolonged heat, sunlight, and ozone sources also supports tire condition between drives.
