The 2000 Audi A6 Quattro sits in the era when Audi was firmly establishing the A6 as a refined all-weather sport sedan and wagon, blending quattro traction with understated executive-car styling. For owners today, that means tire fitment is tied closely to the exact drivetrain and trim configuration rather than a one-size-fits-all answer. This model uses four primary radial tire sizes: 215/55R16, 205/55R16, 235/50R16, and 255/40R17. Available choices range from blackwall performance-oriented radials to American Classic redline and wide whitewall options in select 16-inch sizes. The right choice starts with confirming the sub-model and wheel diameter, then matching the tire’s look and driving intent to the car.
Which Tire Size Is Right for The 2000 Audi A6 Quattro
The 2000 Audi A6 Quattro uses four different primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Three fitments use 16-inch rims, while one uses a 17-inch rim, so the first step is confirming both the specific A6 Quattro version and the wheels currently on the car before comparing tire choices.
In 215/55R16, the 215 is the nominal section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 16 is the rim diameter in inches. This is a modern metric radial fitment for the 2000 Audi A6 Quattro, giving buyers a contemporary sizing format rather than a vintage bias-ply designation. Available options include BFGoodrich blackwall performance tires as well as American Classic radial choices with redline or wide whitewall styling. It is a useful size for owners who want to balance correct fitment with either a sport-oriented look or a more customized appearance.
The 205/55R16 size uses a 205-millimeter nominal section width, a 55-series aspect ratio, radial construction, and a 16-inch rim. On the 2000 Audi A6 Quattro, this size is tied to specific sub-models, so it should not be treated as universal across the full range. Product choice includes several BFGoodrich options, a Michelin radial, and an American Classic wide whitewall, with blackwall and whitewall styling both represented. This fitment gives owners one of the broadest comparison sets on the page, especially if appearance and brand preference both matter.
A 235/50R16 tire has a 235-millimeter nominal section width, a 50-series profile, radial construction, and a 16-inch rim diameter. For the 2000 Audi A6 Quattro, this size applies to a particular sub-model configuration rather than the entire lineup. It represents one of the wider 16-inch fitments used on this car, which makes exact wheel and trim confirmation especially important before selection. Buyers considering this size should focus first on matching the correct vehicle configuration, then on verifying that the wheel setup on the car still reflects the original 16-inch fitment.
The 255/40R17 designation means a 255-millimeter nominal section width, a 40-series aspect ratio, radial construction, and a 17-inch rim. This is the only 17-inch primary fitment among the 2000 Audi A6 Quattro sizes shown here, making wheel-diameter confirmation essential before comparing products. Available tires come from BFGoodrich, Nitto, and Vredestein, all in blackwall form and spread across several performance-oriented radial series. It is the fitment to evaluate when the car is equipped with the larger factory-style wheel package and the buyer wants to stay within that lower-profile 17-inch setup.
Tire fitment for the 2000 Audi A6 Quattro varies by sub-model, and one version uses two different primary sizes depending on wheel setup. Checking the exact badge on the car matters here, because the correct tire is tied to both trim and rim diameter rather than the A6 Quattro name alone.

2000 Audi A6 Quattro 2.7T
The 2000 Audi A6 Quattro 2.7T uses a single 16-inch radial fitment, which keeps size selection fairly straightforward once the car has the correct wheels. The main decision then becomes choosing between a more performance-focused blackwall tire or an appearance-driven radial style within that same size.
The 2000 Audi A6 Quattro 2.8 uses one 16-inch radial tire size, so fitment is consistent as long as the wheel setup has not been changed. That makes it easier to compare available brands and sidewall treatments without sorting through multiple primary sizes first.
The 2000 Audi A6 Quattro 4.2 uses either a 16-inch or 17-inch radial tire size, making wheel confirmation the first step before any tire purchase. Once the rim diameter is verified, the choice becomes much clearer because the product selection and tire profile differ between those two fitments.
The 2000 Audi A6 Quattro Avant 2.8 shares a single 16-inch radial fitment, which simplifies replacement when the wagon still carries the proper wheel diameter. Buyers can then focus on whether they want a standard blackwall presentation or a more distinctive whitewall-style radial option.
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.

These FAQs focus on the exact tire sizes used on the 2000 Audi A6 Quattro, how fitment changes by sub-model, and what to compare when choosing among available radial tires, wheel diameters, and appearance options.
Tire Size & Fitment
What tire size fits a 2000 Audi A6 Quattro?
The 2000 Audi A6 Quattro uses four primary tire sizes: 215/55R16, 205/55R16, 235/50R16, and 255/40R17. The correct size depends on the exact sub-model, with the 2.7T using 215/55R16, the 2.8 and Avant 2.8 using 205/55R16, and the 4.2 using either 235/50R16 or 255/40R17.
That means the first step is identifying the exact version of the car and confirming the wheel diameter currently installed. A6 Quattro cars in this generation may look similar at a glance, but the tire size is not shared across the full lineup, and the 4.2 especially requires extra attention because it appears with both 16-inch and 17-inch fitments.
What size rim does a 2000 Audi A6 Quattro use?
The 2000 Audi A6 Quattro uses either a 16-inch or 17-inch rim, depending on sub-model and tire size. The 215/55R16, 205/55R16, and 235/50R16 fitments all use 16-inch rims, while the 255/40R17 fitment uses a 17-inch rim.
Wheel diameter should be confirmed before comparing tires, because a 16-inch tire cannot be mounted on a 17-inch rim and vice versa. It is also worth checking whether the car still has its original wheel setup, since aftermarket wheels or previous owner changes can leave a car wearing a size that does not match the original sub-model fitment.
Do all 2000 Audi A6 Quattro sub-models use the same tire size?
No, the 2000 Audi A6 Quattro sub-models do not all use the same tire size. The 2.7T uses 215/55R16, the 2.8 and Avant 2.8 use 205/55R16, and the 4.2 appears with either 235/50R16 or 255/40R17.
This variation matters because tire selection starts with the exact sub-model, not just the A6 Quattro model name. A buyer looking at a 4.2 should also confirm whether the car is on 16-inch or 17-inch wheels, while 2.8 and Avant 2.8 owners can narrow the search more quickly because their fitment is shared.
Choosing the Right Tire
What should I consider when choosing a 2000 Audi A6 Quattro tire?
Start with the correct primary tire size for the exact 2000 Audi A6 Quattro sub-model, then confirm the wheel diameter on the car. Every fitment here is radial, but the available choices still differ by brand, tread family, sidewall style, rim-width specification, weight, and in some cases stated load capacity.
After the size is confirmed, think about how the car is used and how you want it to look. A blackwall performance radial suits a more contemporary presentation, while certain 16-inch sizes also open the door to redline or wide whitewall styling for a more customized appearance. The right comparison is usually fitment first, then character and appearance.
What sidewall styles are available for 2000 Audi A6 Quattro tires?
Sidewall choice depends on the tire size. Blackwall tires are available across the covered fitments, while 215/55R16 includes redline and wide whitewall choices, and 205/55R16 includes a wide whitewall option in addition to blackwall selections.
That gives some owners room to shape the car’s presentation without leaving the proper size range for the vehicle. A6 Quattro buyers using the 16-inch fitments have the broadest appearance flexibility, while the 255/40R17 size stays focused on blackwall performance-style radials. Sidewall style should be chosen after confirming the exact sub-model and wheel diameter.
What brands offer tires for the 2000 Audi A6 Quattro?
Tires for the 2000 Audi A6 Quattro are available from BFGoodrich, American Classic, Michelin, Nitto, and Vredestein, depending on size. Some fitments have a wider brand spread than others, with 205/55R16 and 255/40R17 offering several comparison points across different radial series.
Brand selection should be weighed alongside the exact size, sidewall style, and wheel specification rather than treated as a separate decision. For example, American Classic appears in appearance-oriented 16-inch options, while the 17-inch 255/40R17 fitment centers on blackwall performance radials from multiple brands. The best comparison is within the correct size, not across the entire model range.
Restoration & Appearance
Which tire should I choose for a period-style 2000 Audi A6 Quattro?
A period-style 2000 Audi A6 Quattro starts with using the correct sub-model tire size and the proper 16-inch or 17-inch wheel diameter. Since this model uses radial fitments throughout, the main appearance choices come from sidewall treatment and tire series rather than deciding between vintage bias-ply and radial construction.
Owners keeping a more original late-1990s and early-2000s look will usually gravitate toward blackwall radials, especially on the larger 17-inch fitment. Buyers building a more individualized show or cruiser presentation may prefer the redline or wide whitewall options available in certain 16-inch sizes. Exact originality questions are best checked against model-specific references and surviving-car examples.
How does tire construction affect the appearance of a restored 2000 Audi A6 Quattro?
On the 2000 Audi A6 Quattro, construction is simpler than on many older collector vehicles because the primary fitments are already radial. That means appearance differences come less from radial-versus-bias choices and more from profile, sidewall style, and the visual character of the tire series available in the correct size.
A blackwall radial tends to preserve the car’s original-era executive and sport-sedan presentation, while redline or wide whitewall options create a more customized look on qualifying 16-inch setups. Getting the size right remains the foundation, because an incorrect diameter or profile can change the visual stance of the car even before the sidewall treatment enters the picture.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2000 Audi A6 Quattro?
Yes, modifications can affect tire fitment on a 2000 Audi A6 Quattro. Aftermarket wheels, suspension changes, altered ride height, or body and fender work can change the space available for the tire and can also affect whether the wheel width still matches the intended tire size.
A modified car should be checked at the wheel, not just by the model name on the title. Measure the installed wheel diameter, confirm wheel width, and look at steering and fender clearance before choosing a replacement tire. That step is especially important on the 4.2, where both 16-inch and 17-inch fitments appear and profile differences are more noticeable.
What should I inspect before driving a 2000 Audi A6 Quattro on new tires?
Before road use, inspect tire pressure, tread condition, sidewalls, and valve stems, and make sure the tires match the wheel diameter and intended position on the car. It is also smart to look over the wheels themselves for damage and confirm that the tires clear suspension parts, inner liners, and fender edges through a full steering sweep.
A newly installed set should be checked again after the first drives for air loss, unusual wear, or any rubbing marks that suggest a wheel or suspension issue. On a quattro sedan or wagon, smooth and predictable road behavior depends on starting with properly mounted, properly inflated tires in the correct size for that exact sub-model.
How often should tires on a 2000 Audi A6 Quattro be inspected?
Tires on a 2000 Audi A6 Quattro should be inspected regularly, especially if the car is driven infrequently or stored for long periods. A visual check for cracking, bulges, cuts, uneven wear, and low pressure should happen before road use, and a more careful inspection should be part of routine maintenance rather than waiting for a problem to appear.
Collector and low-mileage cars often age their tires out before they wear them out, so condition matters as much as tread depth. It also helps to inspect the spare, confirm that all four road tires remain the same size and general condition, and keep the car stored away from prolonged heat, sunlight, moisture, and ozone sources when possible.
