The 1999 Audi A8 represents Audi’s flagship luxury sedan at the close of the 1990s, blending understated design, all-weather confidence, and the aluminum-intensive engineering that set it apart from many full-size competitors of its era. For tire fitment, this exact model uses radial tires in two sizes, 225/55R17 and 225/60R16, so the first step is confirming which wheel diameter is on the car. From there, the decision shifts to the type of tire presentation you want, whether that means a modern blackwall performance-style radial or a more distinctive whitewall or redline treatment. On a sedan like the A8, matching the right size to the actual wheel setup matters just as much as appearance.
Which Tire Size Is Right for The 1999 Audi A8
The 1999 Audi A8 uses two primary tire sizes, and both are radial fitments. The key difference is wheel diameter: one size fits 17-inch wheels and the other fits 16-inch wheels, so confirming the actual rim diameter on the car comes first. Since the A8 Base can use either size, the real decision is matching the wheel setup and then choosing the tire style, series, and sidewall treatment that best suits the car’s intended look and use.
In 225/55R17, the 225 is the nominal section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. This is a modern metric radial size that suits the 1999 Audi A8’s more contemporary wheel fitment and keeps the tire choice in a fully radial format. Available options include BFGoodrich products in blackwall, wide whitewall, and redline styles across g-Force and Silvertown Radial series. This size is the right one to evaluate when the car is equipped with 17-inch wheels and you want to balance proper fitment with either a performance-oriented or restoration-inspired presentation.
In 225/60R16, the 225 is the nominal width in millimeters, 60 is the aspect ratio, R indicates radial construction, and 16 is the required wheel diameter in inches. For the 1999 Audi A8, this size keeps the fitment in a modern radial format while matching cars fitted with 16-inch rims. Product choices include BFGoodrich, Goodyear, and Travelstar offerings, with sidewall treatments such as raised-yellow-letter, redline, pin-white-stripe, wide whitewall, and narrow whitewall. This size deserves a close look when the car wears 16-inch wheels and the goal is to match both the wheel diameter and the visual character you want.
Sub-model fitment is straightforward here because the covered 1999 Audi A8 Base can use either primary tire size. What matters most is not trim identification, but confirming whether the car is currently fitted with 16-inch or 17-inch wheels before selecting tires.

Common 1999 Audi A8 tire questions usually come down to size selection, wheel diameter, sidewall style, and how to choose among the available radial options. The answers below focus on fitment, appearance, and practical checks before road use.
Tire Size & Fitment
What tire size fits a 1999 Audi A8?
A 1999 Audi A8 uses either 225/55R17 or 225/60R16, and both are radial tire sizes. The difference between them is wheel diameter, with one size built for a 17-inch rim and the other for a 16-inch rim, so both can be correct depending on the wheel package installed on the car.
That means the first step is checking the actual wheels on the car rather than choosing by appearance alone. A used A8 may no longer have its original wheel setup, so verifying the rim diameter on the wheel itself helps prevent ordering the right tire size for the wrong wheel.
What size rim does a 1999 Audi A8 use?
The 1999 Audi A8 uses either a 16-inch or 17-inch rim, depending on which of its two primary tire sizes is on the car. The 225/60R16 size belongs on a 16-inch wheel, while the 225/55R17 size belongs on a 17-inch wheel.
Rim diameter needs to match the tire exactly, so this is the most important fitment check before comparing brands or sidewall styles. Wheel width also matters once the correct diameter is confirmed, especially if the car has aftermarket wheels or if tire choices with different approved rim-width ranges are under consideration.
Does the 1999 Audi A8 Base use the same tire size?
The 1999 Audi A8 Base can use both primary sizes associated with this model: 225/55R17 and 225/60R16. Both are radial fitments, so the Base model does not narrow the choice to a single tire size by itself.
In practical terms, identifying the sub-model is less important than verifying the wheel diameter actually installed on the car. Once that is confirmed, tire selection becomes much easier because you can focus on the correct size and then compare series, sidewall style, and other product differences within that fitment.
Choosing the Right Tire
What should I consider when choosing a tire for a 1999 Audi A8?
Start with the correct primary size for the wheels on the car: 225/55R17 for 17-inch rims or 225/60R16 for 16-inch rims. After size, compare the tire’s intended character, such as a more performance-oriented blackwall radial versus a Silvertown-style tire with redline or whitewall treatment.
It also helps to compare approved rim-width specifications, load figures where shown, and the visual style you want on the car. A 1999 A8 can lean toward a clean modern look or a more distinctive presentation, but the tire still needs to match the wheel dimensions and the car’s real-world setup.
What sidewall styles are available for 1999 Audi A8 tires?
Sidewall choices for the 1999 Audi A8 include blackwall, redline, wide whitewall, pin-white-stripe, narrow whitewall, and raised-yellow-letter treatments, depending on tire size and series. That gives this model an unusually broad range of visual options for a late-1990s luxury sedan.
The right choice depends on how the car is being presented. Blackwall keeps the look closer to a modern sport-luxury sedan, while whitewall, redline, or stripe treatments create a more customized or collector-oriented appearance. Once the proper tire size is confirmed, sidewall style becomes one of the easiest ways to shape the car’s personality.
What brands offer tires for the 1999 Audi A8?
Tires for the 1999 Audi A8 are available from BFGoodrich, Goodyear, and Travelstar across the two primary radial sizes. BFGoodrich appears in both performance-style g-Force offerings and Silvertown Radial styles, while Goodyear and Travelstar add distinct sidewall and series choices in 225/60R16.
Brand selection should come after confirming the correct size and wheel diameter. From there, compare each tire by series, sidewall presentation, approved rim-width range, and any load information shown. The strongest choice is the one that matches the car’s wheel setup and the owner’s goals, not simply the most familiar brand name.
Restoration & Appearance
Which tire should I choose for a period-style 1999 Audi A8?
A period-style 1999 Audi A8 tire choice starts with the correct radial size for the car’s wheels, then moves to appearance. Within those sizes, blackwall options preserve a clean late-1990s luxury-sedan look, while Silvertown Radial whitewall or redline versions create a more distinctive collector presentation.
The best visual fit depends on whether the car is being preserved in a restrained original-era spirit or interpreted with more custom character. Anyone pursuing strict authenticity should compare tire appearance against period photos, original sales material, and marque-specific references, since sidewall treatment alone does not confirm exact historical correctness.
How does tire construction affect the appearance of a restored 1999 Audi A8?
On a 1999 Audi A8, construction changes the look less dramatically than on older collector vehicles because both primary fitments are already radial. The bigger appearance difference comes from sidewall style, with blackwall presenting a more contemporary look and redline, whitewall, or stripe designs giving the car a more stylized visual identity.
That makes this car more about presentation within the correct radial format than about choosing between vintage bias-ply and modern radial construction. A restoration-minded owner should focus on keeping the proper size and wheel diameter first, then selecting the sidewall treatment that best matches the intended finish of the vehicle.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1999 Audi A8?
Yes, modifications can affect tire fitment on a 1999 Audi A8 even when the tire size itself appears correct. Aftermarket wheels, changes in wheel width, suspension alterations, or body modifications can change how a 225/55R17 or 225/60R16 tire sits and whether it maintains proper clearance.
That is why the car’s current setup matters more than assumptions about stock configuration. Checking wheel diameter, wheel width, and visible clearance at the fender and steering components helps avoid problems. A tire can match the nominal size and still need closer review if the vehicle no longer has its original wheel or suspension arrangement.
What should I inspect before driving a 1999 Audi A8 on new tires?
Before driving a 1999 Audi A8 on new tires, inspect the wheels for the correct diameter and condition, confirm the tires are mounted in the proper size, and check inflation pressure carefully. It also makes sense to look over suspension and steering components, especially on a heavier luxury sedan that depends on stable, even tire contact.
A short initial drive should be followed by another look for any rubbing, uneven seating, or pressure loss. Paying attention to sidewall condition, tread uniformity, and how the car tracks on the road can catch issues early. That routine is especially useful when the car has seen wheel changes or long periods of limited use.
How should tires on a collector-era 1999 Audi A8 be maintained?
Tires on a collector-era 1999 Audi A8 should be maintained with regular pressure checks, routine visual inspection, and attention to age-related condition as well as tread depth. Even if the car is driven only occasionally, sidewall cracking, bulges, cuts, and slow air loss deserve close attention before the car returns to regular road use.
Storage conditions matter too. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources helps protect the tires during longer parked periods. An occasional inspection of wear pattern and overall appearance also helps reveal alignment or suspension issues before they become bigger problems on a low-use collector vehicle.
