The 2015 Audi A3 Quattro brought compact Audi luxury into a modern all-wheel-drive package that blended sharp styling, premium road manners, and everyday usability. In sedan and cabriolet form, it sits firmly in the newer enthusiast category where wheel and tire choice affects both appearance and response. This Audi A3 Quattro uses radial tire fitments in three modern metric sizes: 225/45R17, 225/40R18, and 235/35R19. Available choices range from blackwall performance-oriented tires to select raised white letter and redline options in 225/45R17. The key is matching the correct size to the exact sub-model and wheel diameter before comparing series, sidewall style, and intended driving use.
Which Tire Size Is Right for The 2015 Audi A3 Quattro
Three primary tire sizes apply to the 2015 Audi A3 Quattro, and the right one depends on the exact sub-model and wheel diameter. All are radial fitments, but they are tied to 17-inch, 18-inch, or 19-inch wheels, so the first step is confirming the car's actual wheel setup before selecting a tire. Once that is settled, the decision becomes comparing available brands, tire series, and sidewall presentation within the correct size.
Fit(s): Premium Cabriolet, Premium Plus Cabriolet, Premium Plus Sedan, Premium Sedan, Prestige Cabriolet, and Prestige Sedan
Construction: Radial|Rim: 18 in
225/40R18 is a metric radial size with a 225 millimeter section width, a 40-series aspect ratio, and fitment on an 18-inch rim. On the 2015 Audi A3 Quattro, this size is one of the central fitments and suits owners keeping the car on its 18-inch wheel package. Available choices include BFGoodrich and Nitto options, primarily in blackwall form, across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2. It is the size to evaluate when the car is already equipped with 18-inch wheels and the goal is preserving the intended wheel-and-tire proportion.
225/45R17 is a metric radial size that uses a 225 millimeter section width, a 45-series profile, and a 17-inch rim diameter. This fitment applies to certain 2015 Audi A3 Quattro sedan and cabriolet configurations equipped with 17-inch wheels. Product choice is broader here, with BFGoodrich, Nitto, and Pro-Trac offerings, plus blackwall, raised white letter, and redline sidewall treatments. This size deserves a close look when the car wears 17-inch wheels and the owner wants the widest mix of brand, series, and appearance options.
Fit(s): Premium Plus Cabriolet, Premium Plus Sedan, Prestige Cabriolet, and Prestige Sedan
Construction: Radial|Rim: 19 in
235/35R19 is a metric radial size with a 235 millimeter section width, a lower 35-series aspect ratio, and fitment on a 19-inch rim. On the 2015 Audi A3 Quattro, it belongs to specific upper-trim sedan and cabriolet configurations using the 19-inch wheel setup. Choices in this size include blackwall tires from Nitto and BFGoodrich, including NT555 G2 and g-Force Phenom T/A series. It should be considered only after confirming that the car actually has the 19-inch wheel package, since the rim diameter is unique among the A3 Quattro fitments here.
Sub-model fitment matters on the 2015 Audi A3 Quattro because wheel and tire sizing varies between Premium, Premium Plus, and Prestige trims, and between sedan and cabriolet body styles. Many versions share 225/40R18, but the second fitment choice depends on the exact configuration and wheel diameter on the car.

2015 Audi A3 Quattro Premium Cabriolet
The 2015 Audi A3 Quattro Premium Cabriolet uses radial fitments tied to either a 17-inch or 18-inch wheel setup. Tire selection starts with confirming which wheel package is on the car, then comparing the available series and sidewall choices within that correct size.
The 2015 Audi A3 Quattro Premium Plus Cabriolet uses radial tires in either the shared 18-inch fitment or the larger 19-inch setup. That makes wheel diameter the deciding factor before comparing blackwall tire options from the available product range.
The 2015 Audi A3 Quattro Premium Plus Sedan shares the same radial fitment pattern as the Premium Plus Cabriolet, with 18-inch and 19-inch wheel-based tire choices. Verifying the installed wheel diameter is the practical first step before narrowing the tire series that matches the car.
The 2015 Audi A3 Quattro Premium Sedan uses radial tires on either a 17-inch or 18-inch wheel package. Once the wheel diameter is confirmed, the decision shifts to whether a broader mix of brands and sidewall treatments in 17-inch sizing is more relevant than the 18-inch options.
The 2015 Audi A3 Quattro Prestige Cabriolet uses radial fitments associated with 18-inch or 19-inch wheels. Choosing the right tire means confirming the actual wheel size first, then evaluating the blackwall performance-oriented options offered in that fitment.
The 2015 Audi A3 Quattro Prestige Sedan also uses radial tires in either an 18-inch or 19-inch configuration. Its tire choice is straightforward once the wheel diameter is confirmed, since the remaining comparison centers on brand and tire series rather than sidewall style variety.
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 2015 Audi A3 Quattro tire questions usually come down to identifying the correct size by sub-model and wheel diameter, then comparing radial tire choices by brand, sidewall style, and intended use. The answers below also cover wheel changes, maintenance, and pre-drive inspection points.
Tire Size & Fitment
What tire size fits a 2015 Audi A3 Quattro?
The 2015 Audi A3 Quattro uses three primary radial tire sizes: 225/45R17, 225/40R18, and 235/35R19. The exact size depends on the specific sedan or cabriolet sub-model and, just as importantly, the wheel package on the car.
A quick wheel check is the best place to start because these sizes are tied to 17-inch, 18-inch, or 19-inch rims. Once the wheel diameter is confirmed, the remaining choice is easier and centers on the tire series, brand, and sidewall style available in that correct size.
What size rim does a 2015 Audi A3 Quattro use?
A 2015 Audi A3 Quattro can use 17-inch, 18-inch, or 19-inch rims, depending on the sub-model and wheel setup. Those rim diameters correspond to 225/45R17, 225/40R18, and 235/35R19 radial tire fitments.
Matching the tire to the actual rim diameter is essential because a 17-inch tire cannot be mounted on an 18-inch or 19-inch wheel, and vice versa. Owners should also confirm the car has its current original-style wheel package rather than an aftermarket setup before choosing a replacement tire.
Do all 2015 Audi A3 Quattro sub-models use the same tire size?
No. The 2015 Audi A3 Quattro sub-models do not all use the same tire size. Every covered version shares 225/40R18 as one possible fitment, but Premium models also use 225/45R17, while Premium Plus and Prestige models pair the 18-inch fitment with 235/35R19.
That variation means trim level and wheel diameter both matter before selecting a tire. A sedan and cabriolet can share the same fitment pattern within a trim family, but the safest approach is still to confirm the exact sub-model and inspect the wheels currently installed on the car.
Choosing the Right Tire
What should I consider when choosing a tire for a 2015 Audi A3 Quattro?
Start with the correct primary size for the car: 225/45R17, 225/40R18, or 235/35R19. From there, compare the available radial options by brand, tire series, sidewall style, and any useful specifications such as rim-width guidance, weight, or maximum load details where they are stated.
Selection should reflect how the A3 Quattro is actually used. A buyer focused on preserving the existing wheel package may simply want the proper size and a clean blackwall appearance, while someone comparing several options may place more emphasis on series choice, sidewall presentation, or compatibility with the wheel width already on the car.
What sidewall styles are available for 2015 Audi A3 Quattro tires?
Blackwall is the main sidewall style across the 2015 Audi A3 Quattro tire range. In 225/45R17, there are also Pro-Trac Street Pro III options with raised white letter and redline sidewalls, giving that size a broader appearance range than the 18-inch and 19-inch fitments.
Sidewall choice mainly affects the car's presentation rather than its basic fitment category, but it still needs to be selected within the correct tire size. Owners using 17-inch wheels have the most visible style variety, while 18-inch and 19-inch buyers are choosing mostly among blackwall performance-oriented options.
What brands offer tires for the 2015 Audi A3 Quattro?
Tires for the 2015 Audi A3 Quattro are available from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich and Nitto cover multiple fitments, while Pro-Trac appears in 225/45R17 with Street Pro III options in different sidewall treatments.
Brand comparison only matters after the right size has been confirmed for the car's wheel package. A buyer on 17-inch wheels will see the broadest brand and style spread, while 18-inch and 19-inch fitments focus more tightly on blackwall radial choices in performance-oriented series.
Restoration & Appearance
Which tire should I choose for a period-style 2015 Audi A3 Quattro?
A period-style choice for a 2015 Audi A3 Quattro starts with keeping the correct original-type wheel diameter and matching tire size for the exact sub-model. Since this car uses modern metric radial fitments, the most natural visual approach is usually a properly sized radial that maintains the car's intended wheel-and-tire proportion.
Appearance then comes down to whether the goal is a restrained modern look or something more distinctive. Blackwall options suit the A3's contemporary character, while 225/45R17 opens the door to raised white letter or redline styling for owners who want a more customized presentation without changing the basic fitment format.
How does tire construction affect the appearance of a restored 2015 Audi A3 Quattro?
On a 2015 Audi A3 Quattro, tire construction is straightforward because the primary fitments are all radial. That means the visual differences come less from bias-ply-versus-radial character and more from factors such as sidewall treatment, profile, and whether the car sits on 17-inch, 18-inch, or 19-inch wheels.
Owners trying to preserve a clean, era-appropriate look should focus on keeping the correct size and wheel diameter for the sub-model first. After that, blackwall, redline, or raised white letter styling can influence the final presentation, especially on 225/45R17, without changing the basic radial construction the car was built around.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Audi A3 Quattro?
Yes. Modifications can affect tire fitment on a 2015 Audi A3 Quattro even when the nominal tire size looks close to stock. Aftermarket wheels, changes in wheel width, suspension lowering, alignment changes, or body clearance differences can all alter how a 225/45R17, 225/40R18, or 235/35R19 tire sits on the car.
That is why wheel diameter alone is not the only check. Owners should verify actual wheel width, inspect inner and outer clearance, and make sure the tire chosen matches the current setup rather than assuming the car still follows its original sub-model package.
What should I inspect before driving a 2015 Audi A3 Quattro on new tires?
Before driving a 2015 Audi A3 Quattro on new tires, inspect the wheel diameter, confirm the installed tire size matches the car's setup, and check for proper mounting and inflation. It also helps to look over the wheels themselves for damage, bent rims, or signs of previous tire rub.
A short clearance check is worthwhile with the steering turned and the suspension loaded normally. After the first miles, recheck pressure and watch for vibration, uneven contact, or any indication that the car has alignment issues or wheel changes that affect how the new tires are sitting.
How often should tires on a 2015 Audi A3 Quattro be inspected?
Tires on a 2015 Audi A3 Quattro should be inspected regularly rather than only when tread looks low. Frequent visual checks for cuts, bulges, uneven wear, cracking, or slow air loss are especially important on a car that may alternate between daily use and longer parked periods.
A practical routine is to inspect the tires whenever pressure is checked and again before any longer trip. Paying attention to wear pattern changes can also reveal wheel alignment or suspension issues early, which matters on a vehicle that uses lower-profile radial sizes across 17-inch, 18-inch, and 19-inch wheel packages.
