The 1998 Audi A6 Quattro sits in the era when Audi was firmly establishing its reputation for all-weather luxury sedans and wagons with confident Quattro traction and understated European design. For owners today, tire choice matters because this A6 Quattro uses two primary radial sizes, 195/65R15 and 205/55R16, depending on wheel setup rather than a single universal fitment. That makes wheel diameter the first thing to confirm before choosing a tire. Available options center on modern radial construction, with differences in brand, series, and even sidewall presentation. Whether the goal is everyday road use or a more distinctive appearance, the right choice starts with matching the car's actual wheel and tire combination.
Which Tire Size Is Right for The 1998 Audi A6 Quattro
The 1998 Audi A6 Quattro uses two primary tire sizes, and both are radial fitments tied to different wheel diameters. Before choosing a tire, the key step is confirming whether the car is on 15-inch or 16-inch wheels, since both the Avant and Base models can use either size. Once wheel diameter is confirmed, the decision shifts to selecting the right tire series, brand, and sidewall style for how the car will be driven and presented.
195/65R15 is a metric radial size in which 195 is the nominal section width in millimeters, 65 is the aspect ratio, R identifies radial construction, and 15 is the rim diameter in inches. On a 1998 Audi A6 Quattro, this size represents one of the car's primary modern radial fitments and is tied to a 15-inch wheel. It suits owners who are confirming an original-style wheel diameter rather than moving to the larger 16-inch setup. The practical step is making sure the car actually wears 15-inch rims before comparing tire choices.
205/55R16 is a metric radial size with a 205-millimeter nominal section width, a 55-series profile, radial construction, and a 16-inch rim diameter. For the 1998 Audi A6 Quattro, this size is the other primary fitment and opens the most visible product selection, including BFGoodrich, Michelin, and American Classic options in blackwall and wide whitewall styles across several tire series. That makes it a useful size for buyers balancing a more modern performance-oriented look against a more customized or distinctive appearance. Confirming the wheel diameter remains essential before making the final choice.
Tire fitment is straightforward across the covered 1998 Audi A6 Quattro sub-models because both the Avant and Base can use the same two primary sizes. The important check is not the sub-model itself so much as the actual wheel diameter currently on the car.

1998 Audi A6 Quattro Avant
The 1998 Audi A6 Quattro Avant can use either of the vehicle's two primary radial tire sizes, depending on whether it has 15-inch or 16-inch wheels. That means tire selection starts with wheel confirmation, then moves to the preferred brand, tire series, and sidewall style within the correct size.
The 1998 Audi A6 Quattro Base shares the same overall fitment pattern as the Avant, with both primary radial sizes applicable according to wheel diameter. Once the rim size is verified, the next step is comparing the available tire choices for road use, appearance, and wheel compatibility.
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.

Tire Size & Fitment
What tire size fits a 1998 Audi A6 Quattro?
A 1998 Audi A6 Quattro uses two primary tire sizes: 195/65R15 and 205/55R16. Both are radial sizes, and both the Avant and Base sub-models can use either one depending on the wheel diameter installed on the car.
That means there is not one universal size for every 1998 A6 Quattro in the field today. The most important step is checking the actual wheel diameter on the vehicle before choosing a tire, especially if the car has changed hands or received replacement wheels over the years.
What size rim does a 1998 Audi A6 Quattro use?
The 1998 Audi A6 Quattro uses either a 15-inch or 16-inch rim, matching its two primary tire sizes. The 195/65R15 size fits a 15-inch rim, while the 205/55R16 size fits a 16-inch rim.
Rim diameter is the first fitment detail to confirm because it determines which tire size even belongs in the conversation. A quick check of the wheel itself or the current tire sidewall usually settles the question, and that should be done before comparing brands, sidewall styles, or tire series.
Do all 1998 Audi A6 Quattro sub-models use the same tire size?
The 1998 Audi A6 Quattro Avant and 1998 Audi A6 Quattro Base follow the same fitment pattern. Both sub-models can use 195/65R15 or 205/55R16, so the size is tied to the wheel setup rather than to a unique sub-model-only tire requirement.
That makes sub-model identification less important than confirming what is actually on the car now. If the vehicle still has its original wheel style the choice may be straightforward, but any wheel replacement or upgrade means the current rim diameter should be verified before selecting new tires.
Choosing the Right Tire
What should I consider when choosing a tire for a 1998 Audi A6 Quattro?
Start with the correct primary size for the car's wheels, either 195/65R15 or 205/55R16. From there, the main considerations are radial construction, rim compatibility, the intended use of the car, and whether the owner wants a more understated blackwall look or something more distinctive.
On a Quattro sedan or wagon, tire choice also needs to respect the actual wheel setup currently installed. It is smart to compare the tire's approved rim-width range, review any load information that is given, and make sure the final selection suits the car's present wheel and suspension condition.
What sidewall styles are available for 1998 Audi A6 Quattro tires?
Among the available 205/55R16 options, sidewall choices include Blackwall and Wide Whitewall. Blackwall keeps the presentation more modern and understated, while a wide whitewall creates a noticeably different visual statement on the car.
Sidewall style is mostly an appearance decision once the correct tire size has been confirmed. A buyer who wants the car to stay closer to its late-1990s luxury-sport character will usually focus on blackwall tires, while a custom-oriented build may lean toward the wide whitewall option in the same size.
What brands offer tires for the 1998 Audi A6 Quattro?
For the 205/55R16 fitment, available brands include BFGoodrich, Michelin, and American Classic. Those choices cover several tire series, so the decision is not only about brand name but also about the character and appearance of the specific tire being considered.
A useful way to compare them is to look at the exact size, rim-width range, sidewall style, and any load or weight details that matter to the car's intended use. Choosing among brands makes more sense after the correct wheel diameter has already been confirmed on the vehicle.
Restoration & Appearance
Which tire should I choose for a period-style 1998 Audi A6 Quattro?
A period-style approach starts with using the correct primary size for the wheel actually on the car, either 195/65R15 or 205/55R16, and staying with radial construction. From there, a blackwall tire usually preserves the most natural late-1990s European luxury-sport presentation.
Appearance matters, but fitment still comes first. Owners pursuing a highly accurate restoration should compare the car's current setup with original vehicle literature, window-sticker records, or marque-specific references so the final tire choice reflects the wheel and trim configuration being restored.
Does correct tire fitment matter for a 1998 Audi A6 Quattro restoration?
Correct tire fitment matters because wheel diameter and tire profile strongly influence how a 1998 Audi A6 Quattro sits and looks. Using the proper 15-inch or 16-inch size keeps the car visually balanced and avoids a replacement that feels out of step with the vehicle's original character.
It also affects practical details beyond appearance. A restoration-minded owner should confirm the present wheels, compare the intended tire size to the car's actual setup, and choose a sidewall style that supports the desired presentation without assuming every available tire in the size suits the same build goal.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1998 Audi A6 Quattro?
Yes, modifications can affect tire fitment on a 1998 Audi A6 Quattro. Aftermarket wheels, changes in wheel width, altered offset, suspension work, or lowered ride height can all change how a 195/65R15 or 205/55R16 tire sits in the wheelwell.
That is why the current setup should be checked before replacing tires, especially on an older car that may no longer be exactly as built. Steering clearance, fender clearance, and the actual wheel dimensions matter just as much as the tire size printed on the sidewall when modifications are involved.
What should I inspect before driving a 1998 Audi A6 Quattro on new tires?
Before putting a 1998 Audi A6 Quattro back into regular road use, inspect the wheels, valve stems, and overall tire installation, then confirm the tires are properly inflated and seated. It is also wise to check for any existing suspension or alignment issues that could affect tire wear.
A longer look around the car helps too. Make sure there is no rubbing at full steering lock, watch for uneven old-tire wear that hints at mechanical problems, and verify that the wheel hardware and hubs are in good condition so the new tires are not being asked to compensate for unrelated issues.
How often should tires on a 1998 Audi A6 Quattro be inspected?
Tires on a 1998 Audi A6 Quattro should be inspected regularly, not only by mileage but also by time, because many older luxury cars see intermittent use. Sidewall cracking, air loss, bulges, cuts, and uneven tread wear are all worth checking before routine driving and before longer trips.
Collector-era habits apply even to a later model like this one if it spends long periods parked. Tire pressure should be checked often, and the car should not sit indefinitely on aging tires without a close visual inspection, especially if it has been stored in heat, sunlight, or damp conditions.
