The 2017 Audi S3 sits in the modern sport-sedan sweet spot, blending compact Audi proportions with the sharper pace and all-weather confidence that made the S-badged small chassis so appealing. Buyers looking at one today are usually balancing performance-minded road use with the need to keep the car's stance and response in character. This model uses radial tires in two fitments, 225/40R18 and 235/35R19, so the first decision is confirming which wheel package is on the car. Available choices center on blackwall performance radials from BFGoodrich and Nitto. That makes tire selection less about vintage-style construction and more about exact size, wheel compatibility, and how the car is currently equipped.
Which Tire Size Is Right for The 2017 Audi S3
The 2017 Audi S3 uses two primary tire sizes, and the difference comes down to wheel diameter rather than a change from bias-ply to radial construction. Both Premium Plus and Prestige models can use either fitment, so the first step is confirming whether the car is riding on 18-inch or 19-inch wheels before comparing tire options.
225/40R18 is a metric radial size in which 225 identifies the nominal section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 18 is the wheel diameter in inches. On a 2017 Audi S3, this size matches the 18-inch wheel fitment and keeps the selection firmly in modern performance radial territory. Available choices include BFGoodrich and Nitto products, all in blackwall form, with series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2. This is the size to evaluate when the car has 18-inch wheels and the goal is to stay with the proper low-profile S3 fitment format.
235/35R19 is also a metric radial size, with 235 giving the nominal section width in millimeters, 35 marking the aspect ratio, R showing radial construction, and 19 identifying the wheel diameter in inches. For the 2017 Audi S3, this size belongs to the 19-inch wheel setup and continues the car's modern, low-profile performance tire theme. Available tires in this fitment include blackwall options from Nitto and BFGoodrich, including Nitto NT555 G2 and BFGoodrich g-Force Phenom T/A. This size deserves a close look when the car is already equipped with 19-inch wheels and maintaining the correct wheel-to-tire relationship is the priority.
Tire fitment for the 2017 Audi S3 is straightforward because both covered sub-models use the same two tire-size options. The important step is not choosing between Premium Plus and Prestige, but confirming whether the car has the 18-inch or 19-inch wheel setup.

2017 Audi S3 Premium Plus
The 2017 Audi S3 Premium Plus uses the same two radial tire fitments found across this model range, so wheel diameter is the real separator. Tire selection starts with confirming whether the car is on 18-inch or 19-inch wheels, then comparing the available blackwall performance radials in that exact size.
The 2017 Audi S3 Prestige follows the same fitment pattern, with both primary radial tire sizes applying depending on wheel package. That means the practical decision is matching the tire to the car's actual wheel diameter and then choosing among the available performance-oriented blackwall options.
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 2017 Audi S3?
The 2017 Audi S3 uses two tire sizes: 225/40R18 and 235/35R19. Both are radial metric performance sizes, and both appear on this exact model year. Premium Plus and Prestige versions can use either size, so the fitment question is tied to the wheel package rather than to a separate sub-model-only tire specification.
The key step is to verify the wheels currently on the car before choosing a tire. An 18-inch wheel takes 225/40R18, while a 19-inch wheel takes 235/35R19. If the car has been changed from stock-style wheels, confirm the actual wheel diameter and width before comparing tires.
What size rim does a 2017 Audi S3 use?
A 2017 Audi S3 uses either an 18-inch or 19-inch rim, depending on which tire size is on the car. The 225/40R18 fitment matches an 18-inch wheel, and the 235/35R19 fitment matches a 19-inch wheel. Both sizes are part of this model's proper radial fitment range.
Checking the rim diameter first prevents the most common ordering mistake on this car. The size molded on the sidewall and the actual wheel measurement should agree, and wheel width also matters when comparing tire choices. Cars with aftermarket wheels should be measured rather than assumed to still match the original wheel package.
Do all 2017 Audi S3 sub-models use the same tire size?
The 2017 Audi S3 Premium Plus and Prestige share the same two tire-size options: 225/40R18 and 235/35R19. That means there is no separate tire size reserved only for one of these covered sub-models. The real fitment difference is wheel diameter, not trim level.
That shared fitment makes the buying process simpler, but it does not remove the need to inspect the car itself. A Premium Plus could be on 18-inch wheels while another could be on 19-inch wheels, and the same is true for Prestige. Matching the tire to the actual wheel setup is what matters most.
Choosing the Right Tire
What should I consider when choosing a 2017 Audi S3 tire?
Start with the exact tire size already matched to the wheel diameter on the car: 225/40R18 for 18-inch wheels or 235/35R19 for 19-inch wheels. From there, compare radial construction details, load information where stated, and the tire series available in that size. On this S3, the choice is among modern blackwall performance radials rather than vintage-style constructions.
The better comparison points are wheel compatibility, intended road use, and whether the car remains close to its original wheel setup. Some products also include rim-width guidance, which is helpful when aftermarket wheels are involved. Choosing by exact fitment first keeps the car's handling balance and tire-to-wheel relationship in the proper range.
What brands offer tires for the 2017 Audi S3?
Tires for the 2017 Audi S3 are available from BFGoodrich and Nitto in the listed fitments. BFGoodrich appears in both 18-inch and 19-inch applications, and Nitto is also available across the S3's supported sizes. All of the available choices here are radial blackwall performance tires.
Brand should be one part of the decision, but not the only one. It still matters whether the tire is offered in the exact size your wheels require and whether the series characteristics suit the way the car is driven. Comparing wheel-width specs and load details where given is especially useful on modified cars.
What tire series are available for the 2017 Audi S3?
The available tire series for the 2017 Audi S3 include BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. These series appear across the S3's 225/40R18 and 235/35R19 fitments, depending on the exact wheel diameter.
Series names matter because they help separate one radial performance option from another within the same size family. Once the correct size is confirmed, comparing by series can narrow the choice without losing fitment discipline. It is still wise to check wheel-width compatibility and any stated load specification before making a final selection.
Restoration & Appearance
Which tire should I choose for a period-style 2017 Audi S3?
A period-style approach on a 2017 Audi S3 still means staying with the correct modern radial size for the wheel package already on the car. That points to either 225/40R18 or 235/35R19, both in low-profile blackwall form. This is a late-model performance sedan, so appearance is tied more to proper size and stance than to whitewalls or vintage sidewall treatments.
The most convincing presentation usually comes from preserving the correct relationship between tire profile and wheel diameter. Choosing a tire that suits the car's original visual character starts with exact fitment, then moves to brand and series preference. If originality matters closely, compare the car to period photos, window-sticker information, or marque-specific references.
Does correct tire fitment matter for a 2017 Audi S3 restoration?
Correct tire fitment matters on a 2017 Audi S3 because the car's appearance and road manners depend heavily on the proper low-profile size. Using 225/40R18 on 18-inch wheels or 235/35R19 on 19-inch wheels keeps the visual balance in line with the S3's intended sport-sedan character. Even small departures can change how the car sits and looks.
Restoration-minded buyers should think beyond tread alone and inspect wheel diameter, wheel width, and whether the car has been altered from its original-style setup. A tire can be the right general type and still look out of place if the wheel package has changed. Accurate fitment supports both presentation and predictable clearance around the body and suspension.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Audi S3?
Yes, modifications can change tire fitment on a 2017 Audi S3 even when the tire size sounds close to stock. Aftermarket wheels, different wheel widths, altered offsets, lowered suspension, or body changes can affect clearance at the fenders, struts, and steering range. That matters with either of the S3's low-profile radial sizes.
A modified S3 should be checked as it sits rather than matched by model year alone. Measure the actual wheel diameter and width, confirm the tire size on the car, and inspect for rubbing marks or limited clearance at full lock and full suspension travel. Those steps are especially important before replacing only one axle set.
What should I inspect before driving a 2017 Audi S3 on new tires?
Before driving a 2017 Audi S3 on new tires, inspect tire pressure, bead seating, valve stems, wheel condition, and lug hardware torque. It also helps to confirm that the installed size matches the wheel diameter and that there is no contact with suspension or body components. On a performance sedan, even a small fitment issue can become obvious quickly.
A short, careful road test is the right next step. Listen for rubbing, feel for vibration, and recheck pressures after the first drive. Looking over alignment wear patterns on the old tires can also be useful, because unusual shoulder wear or uneven tread loss may point to suspension or alignment issues worth addressing at the same time.
How often should tires on a 2017 Audi S3 be inspected?
Tires on a 2017 Audi S3 should be inspected regularly rather than only at replacement time. Check them for pressure loss, uneven tread wear, cuts, bulges, and sidewall damage, especially because the car uses low-profile radial sizes that can be more sensitive to wheel and road impacts. Frequent visual checks are a smart routine.
Inspection becomes even more important if the car is driven hard, stored for stretches, or runs aftermarket wheels. Looking at the inner sidewall and shoulder area can reveal problems that are easy to miss from the outside. Any sign of repeated air loss, unusual wear, or vibration deserves a closer fitment and condition review before longer trips.
