The 1993 Audi S4 arrived as a discreetly serious performance sedan from the early 1990s, blending turbocharged Audi character with all-weather capability and understated executive-car styling. It occupies an interesting place in Audi enthusiast circles because it delivers real performance without the flash of later sport sedans. Tire fitment on the 1993 Audi S4 centers on two radial sizes, 215/60R15 and 225/50R16, so the first step is confirming which wheel diameter is on the car. From there, the choice shifts toward blackwall performance tires or more appearance-driven options such as redline, raised white letter, or wide whitewall in 15-inch fitment. That makes wheel verification especially important on cars that may have changed hands or been modified over time.
Which Tire Size Is Right for The 1993 Audi S4
The 1993 Audi S4 uses two primary tire sizes, and both are radial fitments tied to different wheel diameters: 215/60R15 on a 15-inch rim and 225/50R16 on a 16-inch rim. Because the same Base sub-model can be found with either size, confirming the actual wheel diameter on the car is the first step before comparing tire style, series, and overall driving intent.
The 215/60R15 size uses a modern metric radial format: 215 is the nominal section width in millimeters, 60 is the aspect ratio, R identifies radial construction, and 15 is the rim diameter in inches. On the 1993 Audi S4, this size supports a more versatile mix of touring, classic-inspired, and appearance-oriented choices. Available options include American Classic, BFGoodrich, Dunlop, Avon, and Vredestein, with sidewall treatments ranging from blackwall to redline, raised white letter, and wide whitewall. This size is worth close attention if the car still wears 15-inch wheels and the goal is to balance fitment, appearance, and road use character.
The 225/50R16 size is also a modern metric radial, with a 225-millimeter nominal section width, a 50-series profile, radial construction, and a 16-inch rim diameter. For the 1993 Audi S4, this fitment leans more squarely toward contemporary performance-oriented blackwall tires. BFGoodrich and Michelin options are available in this size across g-Force and Pilot Sport series, giving the buyer a focused choice within the 16-inch setup. This is the size to evaluate when the car is equipped with 16-inch wheels and the priority is maintaining the intended wheel diameter while comparing performance-style tire lines.
Sub-model fitment is straightforward here because the 1993 Audi S4 Base is the covered configuration, but tire choice still varies by wheel diameter. Checking the car itself matters because the Base model can use either 215/60R15 or 225/50R16 radial tires.

1993 Audi S4 Base
The 1993 Audi S4 Base can use either a 15-inch or 16-inch radial tire setup, so the wheel diameter on the car determines the correct starting point. Once that is confirmed, selection comes down to the type of driving, the preferred tire series, and whether the look should stay purely blackwall or take on a more distinctive sidewall style in 15-inch fitment.
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.

Common 1993 Audi S4 tire questions usually come down to wheel diameter, correct size selection, available radial choices, sidewall style differences in 15-inch fitment, and what to inspect before putting a collector-era sport sedan back on the road.
Tire Size & Fitment
What tire size fits a 1993 Audi S4?
The 1993 Audi S4 uses two primary tire sizes: 215/60R15 and 225/50R16. Both are radial tire fitments, and both apply to the S4 Base configuration, so the correct choice depends on which wheels are currently on the car rather than on a separate trim level distinction.
The practical step is to verify whether the car has 15-inch or 16-inch wheels before choosing tires. A car that has been modified, restored, or simply fitted with a different wheel set over time may no longer match what an owner expects, so wheel diameter should be confirmed directly before comparing brand, series, or sidewall style.
What size rim does a 1993 Audi S4 use?
A 1993 Audi S4 can use either a 15-inch rim or a 16-inch rim, depending on which of its two tire sizes is on the car. The 215/60R15 tire mounts on a 15-inch rim, while the 225/50R16 tire mounts on a 16-inch rim.
That difference matters because tire selection starts with wheel diameter, not just with the vehicle year and model. Measuring the wheel or reading the current tire sidewall is the simplest way to confirm what is installed, and it helps avoid comparing 15-inch classic-style options against 16-inch performance tires that serve a different setup.
Why does the 1993 Audi S4 have more than one tire size?
The 1993 Audi S4 has more than one tire size because it can be found with two different wheel diameters: 215/60R15 on 15-inch rims and 225/50R16 on 16-inch rims. Both sizes are legitimate primary fitments for the model rather than one being a later substitute.
That means the buyer should identify the actual wheel package on the car before moving into product selection. Once wheel diameter is confirmed, the decision becomes much narrower, since the 15-inch size offers broader appearance variety while the 16-inch size is centered on blackwall performance-oriented radial choices.
Choosing the Right Tire
What should I consider when choosing a 215/60R15 tire for a 1993 Audi S4?
Start with the fact that 215/60R15 opens up several different types of radial choices for the 1993 Audi S4. This size is available from American Classic, BFGoodrich, Dunlop, Avon, and Vredestein, with options ranging from classic-style sidewalls to blackwall sport and touring designs.
The best way to narrow that field is to decide what matters most on the car: visual presentation, brand preference, tire series, and wheel-width compatibility. Some 215/60R15 products include redline, raised white letter, or wide whitewall styling, while others keep a more understated blackwall look better suited to an original-seeming sport sedan appearance.
What sidewall styles are available for 1993 Audi S4 tires?
Sidewall style depends on the tire size chosen for the 1993 Audi S4. In 215/60R15, available sidewall treatments include wide whitewall, redline, raised white letter, and blackwall. In 225/50R16, the available choices shown here are blackwall performance tires.
That makes sidewall appearance part of the tire decision rather than a separate cosmetic detail. A buyer using 15-inch wheels has much more freedom to shape the look of the car, while a buyer staying with 16-inch fitment will be choosing mainly among blackwall performance lines and their associated construction and rim-width specifications.
What brands offer tires for the 1993 Audi S4?
Brands available for the 1993 Audi S4 include American Classic, BFGoodrich, Dunlop, Avon, Vredestein, and Michelin. The mix changes by size, with the 215/60R15 fitment offering the broadest range of brands and the 225/50R16 fitment concentrating on BFGoodrich and Michelin performance-oriented choices.
Brand is only one part of the decision, so it helps to compare each option in the context of the actual wheel diameter and intended use. Tire series, sidewall treatment, and the wheel-width range supported by the tire can matter just as much as the name on the sidewall when narrowing the correct option for the car.
Restoration & Appearance
Which tire should I choose for a period-style 1993 Audi S4?
A period-style 1993 Audi S4 tire choice starts with keeping the correct wheel diameter already on the car, then choosing a radial that suits the look you want. The 215/60R15 size offers the widest appearance range, including blackwall, redline, raised white letter, and wide whitewall options, while 225/50R16 stays more performance-blackwall focused.
For a more restrained early-1990s sport sedan presentation, many owners will naturally look toward blackwall designs first. If appearance authenticity matters at a deeper restoration level, it is worth checking model-specific historical references and period photos before selecting a sidewall treatment that changes the visual character of the car.
How does tire construction affect the appearance of a restored 1993 Audi S4?
On the 1993 Audi S4, construction itself is less of a visual dividing line because the primary fitments are radial. The bigger appearance change comes from sidewall treatment and tire series, especially in 215/60R15 where the available choices include blackwall, redline, raised white letter, and wide whitewall designs.
That means a restored S4 can take on very different visual personalities even while staying within the correct size family. Before selecting a tire mainly for appearance, confirm that its rim-width range suits the wheels on the car and that the overall presentation still matches the restoration goal rather than overpowering the Audi’s understated design.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1993 Audi S4?
Yes, modifications can affect tire fitment on a 1993 Audi S4 even when the tire size itself is one of the correct primary options. Changes to wheel diameter, wheel width, offset, suspension height, or brake components can all influence how a 215/60R15 or 225/50R16 tire sits and clears the car.
A modified S4 should be checked at the wheel and fender level rather than assumed to match standard fitment practice. Steering clearance, inner suspension clearance, and body clearance are the main points to review, especially if the car has aftermarket wheels or a lowered stance that changes how the tire moves through its travel.
What should I inspect before driving a 1993 Audi S4 on new tires?
Before driving a 1993 Audi S4 on new tires, inspect the wheels for correct diameter and condition, confirm the tire size matches the wheel setup, and check that each tire is seated properly and inflated evenly. It also helps to look over valve stems, lug hardware, and any signs of rubbing around the wheel openings.
A careful first inspection is especially worthwhile on an older performance sedan that may have seen wheel changes over the years. After the first short drive, recheck pressure and look for any contact marks, vibration, or irregular stance that could point to a wheel-compatibility issue or a suspension problem that needs attention.
How often should tires on a 1993 Audi S4 be inspected?
Tires on a 1993 Audi S4 should be inspected regularly, not just when tread looks worn. A collector-era car that is driven intermittently benefits from routine checks for pressure loss, sidewall cracking, cuts, bulges, uneven wear, and any signs that the tire has been sitting under load for long periods.
A quick visual check before each drive is good practice, and a more thorough inspection should be part of normal seasonal maintenance. Older enthusiast cars often accumulate fewer miles than modern daily drivers, so age, storage conditions, and inactivity can matter as much as mileage when judging whether the tires are still roadworthy.
