The 2002 Audi S4 sits in the B5-era performance sedan and wagon world, blending all-weather confidence with the understated look that made early modern Audis so appealing to enthusiasts. Whether kept as a sharp sport sedan or an Avant with real collector interest, tire choice affects both the way the car presents and how it responds on the road. This exact model uses a 225/45R17 radial tire on a 17-inch rim. Available choices stay within that modern metric fitment but vary by brand, tire series, and sidewall treatment, including blackwall, raised white letter, and redline options. The right selection starts with correct size, then moves to appearance, wheel compatibility, and intended use.
Which Tire Size Is Right for The 2002 Audi S4
The 2002 Audi S4 uses one primary tire size: 225/45R17 in radial construction on a 17-inch rim. That fitment carries across the covered S4 sub-models, so the main decision is not choosing between multiple factory sizes, but selecting the right tire within that size based on wheel compatibility, driving use, and whether you want a more understated or more expressive sidewall style.
225/45R17 is a modern metric radial size in which 225 identifies the nominal section width in millimeters, 45 is the aspect ratio, R marks radial construction, and 17 is the wheel diameter in inches. On the 2002 Audi S4, that means a low-profile radial fitment that matches the car's modern sport-sedan and sport-wagon character. Available options include BFGoodrich, Nitto, and Pro-Trac, with blackwall, raised white letter, and redline sidewall treatments across several tire series. The key is matching the tire to the actual wheel width and the way the car is driven, especially if the vehicle has non-stock wheels or suspension changes.
Tire fitment is straightforward across the covered 2002 Audi S4 sub-models, with the same primary size used on both the sedan and Avant. Checking the exact sub-model still helps confirm that the car remains on the expected 17-inch wheel setup before choosing among available tire styles and series.

2002 Audi S4 Avant
The 2002 Audi S4 Avant uses the same 225/45R17 radial fitment as the other covered S4 configuration. That keeps selection focused on wheel-width compatibility, tire-series character, and whether a blackwall, raised white letter, or redline sidewall better suits the wagon's intended look and use.
The 2002 Audi S4 Base also uses the 225/45R17 radial size on a 17-inch rim. For this sub-model, the real choice is which version of that size makes the most sense for the car's current wheel setup, driving habits, and preferred overall appearance.
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 2002 Audi S4?
The 2002 Audi S4 uses a 225/45R17 radial tire. That size appears across the covered S4 fitments, including the Base and Avant, and it is built for a 17-inch wheel.
That makes the main fitment question fairly simple, but size alone is not the whole decision. It is still worth confirming that the car is wearing the expected 17-inch wheels and that wheel width matches the tire being considered, especially if the S4 has aftermarket wheels, suspension changes, or a previous owner has altered the setup.
What size rim does a 2002 Audi S4 use?
The primary tire fitment for the 2002 Audi S4 is built around a 17-inch rim. The 225/45R17 size uses that 17-inch wheel diameter across the covered S4 configurations.
Wheel diameter should be confirmed before ordering tires, but wheel width matters too. Some available 225/45R17 products are intended for different rim-width ranges, so the best next step is to inspect the actual wheel on the car and compare its width to the tire's approved fitment range rather than assuming every 17-inch wheel is equally suitable.
Do all 2002 Audi S4 sub-models use the same tire size?
Yes. The covered 2002 Audi S4 sub-models use the same primary tire size, 225/45R17, in radial construction. That includes both the S4 Base and the S4 Avant.
Shared size across sub-models simplifies the search, but it does not remove the need to verify the car's actual wheel and suspension setup. A modified Avant or Base model may have different wheels than expected, so confirming wheel width, checking for clearance changes, and selecting the right sidewall style or tire series still matters before making a final choice.
Choosing the Right Tire
What should I consider when choosing a 225/45R17 tire for a 2002 Audi S4?
Start with the correct size, 225/45R17, then compare the details that separate one tire from another. For the 2002 Audi S4, available choices differ by brand, tire series, sidewall style, rim-width specification, and in some cases load and weight figures.
The best match depends on how the car is actually used and how it is set up today. A stock-wheel street car may point to a different choice than an S4 with wider wheels or a more appearance-driven goal, so it helps to compare the wheel width on the car, the desired look, and the product's intended fitment range before deciding.
What sidewall styles are available for 2002 Audi S4 tires?
225/45R17 tires for the 2002 Audi S4 are available in blackwall, raised white letter, and redline sidewall styles. Blackwall choices are the most understated, while raised white letter and redline options give the car a more deliberate visual statement.
Sidewall treatment does not change the required base size, but it can strongly affect the finished look of the car. A buyer trying to keep the S4 subtle may lean toward blackwall, while someone building a more individualized street presentation may prefer RWL or redline, provided the tire also matches the wheel width and intended road use.
What brands offer tires for the 2002 Audi S4?
The 2002 Audi S4 has 225/45R17 tire options from BFGoodrich, Nitto, and Pro-Trac. Those choices span several tire series and include different sidewall presentations within the same overall fitment.
Brand choice should be part of a broader comparison rather than the only factor. It makes sense to look at the tire series, approved rim-width range, sidewall style, and any stated load figures that matter to your setup, then choose the option that aligns with the car's wheels, intended use, and preferred appearance.
Restoration & Appearance
Which tire should I choose for a period-style 2002 Audi S4?
A period-style 2002 Audi S4 still starts with the correct 225/45R17 radial size on a 17-inch wheel. From there, the appearance decision comes down to the tire's sidewall treatment and overall presentation rather than changing to an older sizing system or bias-ply construction.
For a more restrained look, blackwall is the most natural place to begin. Raised white letter or redline versions create a more customized impression, so buyers with restoration-minded goals should compare those visual choices carefully against period photos, marque-club references, and the specific character they want the finished car to convey.
How does tire construction affect the appearance of a restored 2002 Audi S4?
On a 2002 Audi S4, the primary fitment is already radial, so construction does not create the vintage bias-ply-versus-radial appearance question seen on older collector vehicles. The visual character is shaped more by profile, sidewall treatment, and how the tire sits on the wheel.
That means the restoration-oriented buyer should focus on staying with the proper 225/45R17 sizing and choosing a sidewall style that suits the car's intended finish. Checking the wheel width matters here as well, because the way a tire presents on the rim can influence the overall stance and look even when the size itself is correct.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2002 Audi S4?
Yes. Even though the standard size is 225/45R17, modifications can change how that tire fits and functions on a 2002 Audi S4. Aftermarket wheels, altered wheel width, suspension lowering, alignment changes, or body modifications can all affect clearance and tire selection.
That is why the actual car should be checked before settling on a tire. Confirm the wheel diameter and width, inspect inner and outer clearance at full steering lock, and make sure the tire's approved fitment range matches the wheels on the vehicle rather than assuming a stock-size tire will behave the same on every modified setup.
What should I inspect before driving a 2002 Audi S4 on new tires?
Before road use, inspect the wheels for damage, confirm the tires are mounted in the correct 225/45R17 size, and verify proper inflation. It also helps to look for rubbing points, uneven suspension wear, and any signs that the car's alignment may be off.
A short, careful test drive is the next sensible step. Listen for contact over bumps or during full-lock turns, watch for vibration, and recheck pressure after the tires have settled. On a performance-oriented car like the S4, small issues in wheel condition, suspension wear, or alignment can affect both tire life and overall driving feel.
How should 225/45R17 tires on a collector 2002 Audi S4 be maintained?
Collector-use 225/45R17 tires on a 2002 Audi S4 still need regular pressure checks, visual inspection, and periodic evaluation for age-related deterioration. Tread depth matters, but so do sidewall cracking, bulges, cuts, and signs of slow air loss on a car that may sit for extended periods.
Storage conditions play a real role in preserving tires on a low-use S4. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources can help, and it is smart to inspect the tires before each drive rather than assuming low mileage means low risk. Long-stored performance cars deserve especially careful pre-drive checks.
