The 2004 Audi A4 Quattro sits in the B6-era sweet spot, combining compact German luxury with all-wheel-drive confidence in sedan, Avant, and Cabriolet form. It appeals to buyers who want a car that still feels modern enough for regular use while keeping the sharper proportions and road manners that made early-2000s Audi sport sedans so popular. Tire fitment centers on two radial sizes, 215/55R16 and 235/45R17, both used across the A4 Quattro range. That leaves the real decision focused on wheel diameter, tire character, and whether a subtle restoration-minded look or a more contemporary blackwall performance style makes more sense for the car.
Which Tire Size Is Right for The 2004 Audi A4 Quattro
The 2004 Audi A4 Quattro uses two primary tire sizes, and both are radial fitments. The key step is confirming whether the car is equipped with 16-inch or 17-inch wheels, since that determines whether it takes 215/55R16 or 235/45R17. Because both sizes appear across the covered sub-models, wheel diameter matters more than trim name when selecting the correct tire.
Fit(s): 1.8T, 3.0, Avant 1.8T, Avant 3.0, and Cabriolet 3.0
Construction: Radial|Rim: 16 in
215/55R16 is a metric radial size in which 215 identifies the nominal section width in millimeters, 55 is the aspect ratio, R marks radial construction, and 16 is the wheel diameter in inches. On the 2004 Audi A4 Quattro, this size suits cars running 16-inch wheels and keeps the fitment in a modern radial format. Available choices include blackwall, redline, and wide whitewall styles from BFGoodrich and American Classic, with both performance-oriented and appearance-focused series represented. It is a useful size for buyers who want to confirm wheel fit first and then decide whether the car should lean toward a stock-looking road setup or a more customized presentation.

Construction: Radial|Rim: 17 in
235/45R17 is a metric radial size with a 235-millimeter nominal section width, a 45-series profile, radial construction, and a 17-inch rim diameter. For the 2004 Audi A4 Quattro, this size belongs to cars equipped with 17-inch wheels and reflects the lower-profile side of the platform's factory-style fitment range. Product choices here focus on blackwall performance tires from BFGoodrich and Nitto across several series, giving buyers more than one approach within the same basic size. It is the size to evaluate when the car already wears 17-inch wheels and the goal is a cleaner, more contemporary handling-oriented setup.
Tire fitment is straightforward across the 2004 Audi A4 Quattro range because each covered sub-model uses the same two radial size options. The important check is the wheel diameter currently on the car, since either 16-inch or 17-inch wheels may be present regardless of sub-model.

2004 Audi A4 Quattro 1.8T
The 2004 Audi A4 Quattro 1.8T uses the same two radial tire size options found across the broader model range. Tire selection comes down to confirming whether the car has 16-inch or 17-inch wheels, then choosing between a more performance-focused blackwall tire or a more appearance-driven alternative where available.
The 2004 Audi A4 Quattro 3.0 follows the same fitment pattern, with both 215/55R16 and 235/45R17 used depending on wheel setup. That means the next step is verifying the actual wheel diameter on the vehicle before comparing tire series, sidewall treatment, and other product differences.
The 2004 Audi A4 Quattro Avant 1.8T shares the same two radial fitment choices as the sedan versions. For wagon owners, the practical decision is still wheel-based first, followed by whether the tire should emphasize a conventional blackwall look or a more distinctive period-inspired sidewall treatment.
The 2004 Audi A4 Quattro Avant 3.0 also uses either 215/55R16 or 235/45R17 depending on the wheels installed on the car. That keeps fitment simple, but it still pays to confirm the current wheel package before selecting among the available radial tire series and sidewall styles.
The 2004 Audi A4 Quattro Cabriolet 3.0 uses the same pair of radial tire sizes as the rest of the covered Quattro lineup. Choosing the right tire starts with the car's 16-inch or 17-inch wheel diameter, then moves to appearance and driving priorities within the available product range.
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.
Best 2004 Audi A4 Quattro Tires for Sale
Available 2004 Audi A4 Quattro tires span 215/55R16 and 235/45R17 radial fitments from BFGoodrich, American Classic, and Nitto. Buyers can compare blackwall performance tires against redline and wide whitewall alternatives, along with differences in tire series and rim-width specifications.
These 2004 Audi A4 Quattro tire FAQs focus on the two correct sizes, 16-inch versus 17-inch wheel fitment, product and sidewall choices, and the maintenance checks that matter before regular road use.
Tire Size & Fitment
What tire size fits a 2004 Audi A4 Quattro?
The 2004 Audi A4 Quattro uses two primary tire sizes: 215/55R16 and 235/45R17. Both are radial sizes, and both appear across the covered 1.8T, 3.0, Avant, and Cabriolet Quattro sub-models.
The deciding factor is the wheel diameter actually on the car. A4 Quattro models equipped with 16-inch wheels use 215/55R16, while cars with 17-inch wheels use 235/45R17. Because both sizes were used across multiple sub-models, trim name alone is not enough. Check the wheel size before comparing brands, sidewall styles, or tire series.
What size rim does a 2004 Audi A4 Quattro use?
A 2004 Audi A4 Quattro uses either a 16-inch or 17-inch rim, depending on the wheel package on the vehicle. The 215/55R16 tire fits a 16-inch rim, and the 235/45R17 tire fits a 17-inch rim.
That rim diameter check should happen before any tire purchase, especially on older cars that may have had wheel changes over time. Sidewall markings on the current tires and the stamping on the wheels can help confirm what is installed. Once the diameter is verified, it becomes much easier to narrow the choice by construction, tire series, and sidewall appearance.
Do all 2004 Audi A4 Quattro sub-models use the same tire size?
The covered 2004 Audi A4 Quattro sub-models share the same two tire size options rather than each having a unique size. The 1.8T, 3.0, Avant 1.8T, Avant 3.0, and Cabriolet 3.0 can all use either 215/55R16 or 235/45R17, depending on wheel diameter.
That makes fitment more consistent than many year-make-model pages, but it does not remove the need to inspect the car itself. A sedan and an Avant may both fall under the same fitment range while still wearing different wheel packages. Confirm the actual wheel diameter and current setup first, then choose the correct tire within that size.
Choosing the Right Tire
What should I consider when choosing a 215/55R16 or 235/45R17 tire for a 2004 Audi A4 Quattro?
Start with the correct size for the wheels on the car, since the 2004 Audi A4 Quattro uses either 215/55R16 on 16-inch rims or 235/45R17 on 17-inch rims. Both are radial fitments, so the next comparison points are tire series, sidewall style, and intended road use.
A blackwall performance tire gives the car a modern appearance, while redline or wide whitewall options in 215/55R16 create a more customized look. It also helps to compare rim-width compatibility and load figures where they are given. Choosing the right tire means matching the wheel size first, then matching the tire's character to how the Audi is driven and presented.
What sidewall styles are available for 2004 Audi A4 Quattro tires?
Sidewall choices for the 2004 Audi A4 Quattro include blackwall, redline, and wide whitewall, depending on the tire size selected. The broadest sidewall variety appears in 215/55R16, while 235/45R17 products here are blackwall performance-oriented radials.
That means appearance can play a meaningful role in tire selection, especially on a car that has been personalized or is being styled with a more distinctive period-inspired look. A buyer keeping a contemporary Audi presentation may stay with blackwalls, while someone building a more unusual visual theme may look at the redline or whitewall 16-inch options after confirming wheel fitment.
What brands offer tires for the 2004 Audi A4 Quattro?
Tires for the 2004 Audi A4 Quattro are available here from BFGoodrich, American Classic, and Nitto. Brand choice depends partly on tire size, since the 16-inch and 17-inch fitments do not share the same exact product mix.
BFGoodrich appears in both sizes, while American Classic is represented in 215/55R16 and Nitto appears in 235/45R17. That gives the buyer a useful split between appearance-focused options and blackwall performance-style choices. The better approach is not choosing by brand name alone, but comparing the correct size, sidewall treatment, tire series, and rim-width specifications together.
Restoration & Appearance
Which tire should I choose for a period-style 2004 Audi A4 Quattro?
A period-style 2004 Audi A4 Quattro tire choice starts with the correct wheel diameter, then moves to the overall look you want the car to carry. In 215/55R16, the available range includes blackwall, redline, and wide whitewall radials, while 235/45R17 options shown here stay closer to a blackwall sport-sedan appearance.
Because this is a newer collector-era Audi rather than a prewar or muscle-era restoration, period style often means preserving the car's early-2000s character instead of chasing one exact sidewall treatment. Buyers concerned with strict originality should check marque-specific references and the car's own delivery history. For most owners, the right visual match is the one that suits the wheel package and the intended presentation.
How does tire construction affect the appearance of a restored 2004 Audi A4 Quattro?
Tire construction is straightforward on a 2004 Audi A4 Quattro because the primary fitments are radial. The visual difference here comes less from bias-ply versus radial and more from whether the tire has a blackwall, redline, or wide whitewall sidewall treatment.
That matters because a blackwall radial tends to preserve the Audi's original-era sport-luxury feel, while redline or whitewall tires shift the car toward a more customized presentation. Construction is not the restoration debate on this application; appearance is. Once the correct 16-inch or 17-inch size is confirmed, sidewall style becomes the strongest visual choice affecting how finished the car looks.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2004 Audi A4 Quattro?
Yes, modifications can affect tire fitment on a 2004 Audi A4 Quattro even when the tire size itself is correct. Wheel changes, suspension lowering, altered offsets, or body modifications can change clearance at the fender, inner wheelhouse, and steering components.
That is especially important on Quattro cars that may have been upgraded with aftermarket wheels over the years. A 215/55R16 or 235/45R17 tire should always be matched to the actual wheel setup on the car, not assumed from the badge alone. Before road use, turn the steering from lock to lock and inspect for rubbing under normal suspension travel.
What should I inspect before driving a 2004 Audi A4 Quattro on new tires?
Before driving a 2004 Audi A4 Quattro on new tires, inspect wheel condition, confirm the tire size matches the rim diameter, and make sure inflation is set appropriately for the tire and vehicle setup. It is also wise to check that the tires seat evenly and clear suspension and body components.
A careful first inspection should also include lug hardware, visible tread uniformity, and any sign of contact at full steering lock. On a Quattro model, consistency across the vehicle matters, so look at the complete set rather than one corner at a time. After the first miles, recheck air pressure and look again for any rubbing or unusual wear.
How often should tires on a 2004 Audi A4 Quattro be inspected?
Tires on a 2004 Audi A4 Quattro should be inspected regularly, not just when tread looks low. A quick visual check before routine driving and a more careful inspection at intervals for pressure, tread wear, cracking, bulges, and cuts helps catch issues early.
That routine matters even more on cars that see seasonal or occasional use, because age and storage conditions can affect tires long before they appear worn out. Check the sidewalls, tread surface, and valve area, and watch for gradual air loss. Any vibration, pull, or new clearance concern deserves immediate attention before longer road use.
