The 1998 Audi A8 Quattro sits at the point where Audi’s aluminum-intensive flagship sedan had fully established its modern luxury character, blending understated styling with all-wheel-drive confidence. For owners today, tire choice matters as much for stance and road manners as it does for preserving the car’s clean late-1990s presentation. This model uses radial tires in two primary 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 sidewall style, tire series, and whether the goal is a contemporary blackwall look or a more restoration-inspired whitewall or redline presentation.
Which Tire Size Is Right for The 1998 Audi A8 Quattro
The 1998 Audi A8 Quattro uses two primary tire sizes, and the difference comes down to wheel diameter rather than tire construction, since both are radial fitments. The Base sub-model can use either 225/55R17 on a 17-inch rim or 225/60R16 on a 16-inch rim, so identifying the actual wheel size on the car is the first step before comparing brands, sidewall styles, and tire series.
The 225/55R17 size is a metric radial format: 225 is the nominal section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 17 is the rim diameter in inches. On the 1998 Audi A8 Quattro, this size keeps the fitment in a modern radial layout suited to the car’s original era and road-use character. Available choices include BFGoodrich performance-oriented g-Force series in blackwall form as well as Silvertown Radial options with wide whitewall or redline styling. This size makes the most sense after confirming that the car is equipped with 17-inch wheels and the desired visual style matches the car’s intended look.
The 225/60R16 size is also a metric radial, with the same 225-millimeter nominal width but a 60-series profile mounted on a 16-inch rim. For a 1998 Audi A8 Quattro running 16-inch wheels, this is a primary fitment rather than an alternate equivalent. Product choices range from blackwall-free specialty looks such as raised yellow letter and multiple whitewall treatments to redline and standard radial-style offerings from Goodyear, BFGoodrich, and Travelstar. This size is worth evaluating when the car retains or currently uses 16-inch wheels and the buyer wants a broader mix of period-style sidewall treatments.
Sub-model fitment is straightforward here because the covered 1998 Audi A8 Quattro Base uses the same two primary tire sizes found at the model level. What matters most is not trim distinction, but confirming whether the car is sitting on 16-inch or 17-inch wheels before choosing a tire.

These FAQs focus on the real tire decisions for a 1998 Audi A8 Quattro, including which of the two sizes applies, how wheel diameter affects fitment, and how to choose among the available radial styles and product types.
Tire Size & Fitment
What tire size fits a 1998 Audi A8 Quattro?
A 1998 Audi A8 Quattro uses two primary tire sizes: 225/55R17 and 225/60R16. Both are radial sizes, and both apply to the 1998 Audi A8 Quattro Base, so this is not a bias-ply-versus-radial question or a trim-level split in construction.
The deciding factor is the wheel diameter currently on the car. A8s that wear 17-inch wheels use 225/55R17, while cars on 16-inch wheels use 225/60R16. Before choosing a tire, check the wheel size directly and confirm that the wheels are original-style dimensions or, if aftermarket, that their width and clearance still suit the selected tire.
What size rim does a 1998 Audi A8 Quattro use?
The 1998 Audi A8 Quattro 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 mounts on a 16-inch wheel, and the 225/55R17 size mounts on a 17-inch wheel.
Rim diameter should be confirmed before looking at sidewall style or tire series, because a 16-inch tire and a 17-inch tire are not interchangeable. It is also worth checking the actual wheel width, especially if the car has replacement wheels, since individual products within these sizes have their own rim-width compatibility ranges.
Why does the 1998 Audi A8 Quattro have more than one tire size?
The 1998 Audi A8 Quattro has more than one tire size because it can be fitted with either 16-inch or 17-inch wheels. That creates two primary radial fitments: 225/60R16 for the 16-inch setup and 225/55R17 for the 17-inch setup.
For the owner, that means tire selection starts with the wheel already on the car rather than assuming one universal size for every A8 Quattro. Since both sizes are legitimate primary fitments, the practical next step is matching the tire to the wheel diameter and then choosing the appearance and product style that best suits the car.
Choosing the Right Tire
What should I consider when choosing a 225/55R17 tire for a 1998 Audi A8 Quattro?
Start with correct fitment and wheel compatibility. On a 1998 Audi A8 Quattro using 17-inch wheels, 225/55R17 is the primary size, and available choices include BFGoodrich blackwall performance-oriented g-Force lines as well as Silvertown Radial options in wide whitewall and redline form.
The real decision is whether the car is being kept in a more contemporary late-1990s luxury-sedan look or given a more distinctive custom or collector-style presentation. It also helps to compare each tire’s approved rim-width range, since some 225/55R17 options are intended for a narrower width band than others.
What sidewall styles are available for 1998 Audi A8 Quattro tires?
The 1998 Audi A8 Quattro has a wide spread of sidewall styles across its two primary sizes. Depending on the size selected, available treatments include Blackwall, Redline, Wide Whitewall, Narrow Whitewall, Pin-White-Stripe, and Raised-Yellow-Letter.
That variety means the sidewall can significantly change the car’s visual character even when the size stays correct. A blackwall keeps the look more restrained and modern, while whitewall, redline, or raised-letter options create a more custom or period-inspired impression. The best choice depends on the wheel size on the car and the appearance goal.
What brands offer tires for the 1998 Audi A8 Quattro?
Tires for the 1998 Audi A8 Quattro are available from BFGoodrich, Goodyear, and Travelstar. BFGoodrich appears in both 225/55R17 and 225/60R16, while Goodyear and Travelstar appear in 225/60R16 offerings.
Brand matters mostly as part of the overall product character rather than as a standalone answer. Some options lean toward blackwall performance styling, while others focus more on redline or whitewall presentation. Once the correct tire size is confirmed, compare the brand alongside sidewall style, tire series, and rim-width suitability for the actual wheel.
Restoration & Appearance
Which tire should I choose for a period-style 1998 Audi A8 Quattro?
A period-style choice for a 1998 Audi A8 Quattro starts with the correct primary size for the wheel on the car: 225/55R17 for 17-inch wheels or 225/60R16 for 16-inch wheels. From there, the appearance can stay understated with blackwall or shift toward a more expressive look with redline or whitewall options.
Because this is a late-1990s luxury sedan, many owners prefer a tire that complements the car’s original-era proportions without making the sidewall treatment look out of place. If exact historical presentation matters, compare the tire choice against period photos, original sales literature, or marque-specific references before settling on a restoration-oriented look.
How does tire construction affect the appearance of a restored 1998 Audi A8 Quattro?
On a 1998 Audi A8 Quattro, construction is straightforward because the primary fitments are radial. That means the appearance differences come less from choosing between bias-ply and radial and more from selecting the proper size, profile, and sidewall treatment for the car’s wheels and intended presentation.
A blackwall radial keeps the look closest to a restrained modern luxury sedan, while redline, pin-white-stripe, narrow whitewall, or wide whitewall versions push the car toward custom or collector styling. Restored examples usually look most cohesive when the tire profile, rim diameter, and sidewall treatment all support the car’s overall design rather than competing with it.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1998 Audi A8 Quattro?
Yes. A 1998 Audi A8 Quattro may have the correct nominal tire size yet still run into fitment issues if the car has aftermarket wheels, altered wheel width, nonstandard offset, lowered suspension, or body and fender changes. Those changes can affect clearance even when the tire size itself is one of the primary options.
The safest approach is to verify actual wheel diameter first, then inspect wheel width and clearances at full steering lock and normal ride height. A car modified away from its stock-style setup may need closer checking around the inner fender, suspension components, and outer bodywork before settling on a specific tire within 225/55R17 or 225/60R16.
What should I inspect before driving a 1998 Audi A8 Quattro on new tires?
Before road use, inspect the wheels, valve stems, lug hardware, and overall tire seating, and confirm that the tire size matches the wheel diameter on the car. It is also smart to check for any suspension wear or alignment issues that could quickly affect a fresh set of tires.
A collector or low-use A8 deserves a closer walkaround after installation. Look for even clearance, proper inflation, and any sign of rubbing during steering and suspension movement. After the first drive, recheck pressure and inspect for unusual wear or contact marks so small fitment issues can be corrected before they become expensive ones.
How often should tires on a 1998 Audi A8 Quattro be inspected?
Tires on a 1998 Audi A8 Quattro should be inspected regularly, especially if the car is driven infrequently or stored for long periods. Condition matters as much as mileage on a collector-age luxury sedan, so sidewall cracking, tread separation, flat spotting, bulges, cuts, and gradual air loss should all be part of routine checks.
A monthly inspection is a sensible baseline, with an additional check before any longer drive. Cars that sit can age tires without showing much tread wear, and older wheels or suspension components can magnify small problems. Keeping inflation correct and catching early signs of deterioration helps preserve both ride quality and safe road manners.
