The 2019 Audi A3 Quattro blends compact Audi luxury with all-weather traction and the crisp, modern road manners buyers expect from a contemporary sport sedan or cabriolet. In this generation, wheel and tire choice plays a visible role in both stance and response, so fitment matters more than simply matching a badge. This model uses radial tire fitments in 17-, 18-, and 19-inch sizes, depending on the exact sub-model and wheel setup. Available choices range from blackwall performance-oriented tires to a few 17-inch options with raised white letter or redline styling. The key is confirming the exact sub-model and wheel diameter before comparing appearance, series, and road-use priorities.
Which Tire Size Is Right for The 2019 Audi A3 Quattro
The 2019 Audi A3 Quattro uses three primary tire sizes: 225/45R17, 225/40R18, and 235/35R19. All are radial fitments, but they are not used across every version of the car, and the wheel diameter changes with the size. The first step is identifying the exact sub-model and confirming whether the car is on 17-, 18-, or 19-inch wheels before comparing tire series, sidewall style, and other product differences.
Fit(s): Premium Cabriolet, Premium Plus Cabriolet, Premium Plus Sedan, Premium Sedan, Prestige Cabriolet, and Prestige Sedan
Construction: Radial|Rim: 18 in
A 225/40R18 tire has a 225-millimeter nominal section width, a 40-series aspect ratio, radial construction, and fits an 18-inch rim. On the 2019 Audi A3 Quattro, this size sits in the middle of the fitment range and appears across several sedan and cabriolet sub-models. Product choices in this size come from BFGoodrich and Nitto, with blackwall sidewalls and tire series including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This size is a strong reference point when the car already wears 18-inch wheels and the goal is to compare modern radial options without changing wheel diameter.
A 225/45R17 tire uses the same 225-millimeter nominal width as the 18-inch option, but with a taller 45-series profile on a 17-inch rim. For the 2019 Audi A3 Quattro, this size is tied to specific Premium sedan and cabriolet applications rather than the full model range. Available choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, raised white letter, and redline sidewall treatments depending on the tire series. This size deserves a closer look when the car is equipped with 17-inch wheels and you want the broadest appearance variety among the primary fitments.
Fit(s): Premium Plus Cabriolet, Premium Plus Sedan, Prestige Cabriolet, and Prestige Sedan
Construction: Radial|Rim: 19 in
A 235/35R19 tire is wider at 235 millimeters, uses a lower 35-series profile, and fits a 19-inch rim. On the 2019 Audi A3 Quattro, this size belongs to certain Premium Plus and Prestige sedan and cabriolet configurations rather than every sub-model. Current choices in this size include blackwall radials from Nitto and BFGoodrich, with tire series such as NT555 G2 and g-Force Phenom T/A. This fitment should be evaluated when the car is already running 19-inch wheels and the priority is staying with the proper wheel diameter and low-profile tire format.
Sub-model fitment on the 2019 Audi A3 Quattro is not completely uniform, because each version shares one size and then branches to either a smaller or larger wheel package. Checking the exact sedan or cabriolet trim is the easiest way to avoid choosing the right tire size for the wrong wheel diameter.

2019 Audi A3 Quattro Premium Cabriolet
The 2019 Audi A3 Quattro Premium Cabriolet uses radial fitments that pair the shared 18-inch size with a 17-inch option. Tire selection starts with confirming which wheel package is on the car, then comparing blackwall or, in the 17-inch size, more appearance-focused sidewall choices.
The 2019 Audi A3 Quattro Premium Plus Cabriolet uses the common 18-inch radial fitment and also appears with a 19-inch option. That means the buying decision is less about construction and more about confirming wheel diameter before comparing available tire series within the correct size.
The 2019 Audi A3 Quattro Premium Plus Sedan follows the same two-size pattern as other upper sedan trims, with 18-inch and 19-inch radial fitments. The practical step is verifying which wheels are on the car now, especially if it has been changed from its original setup.
The 2019 Audi A3 Quattro Premium Sedan uses the shared 18-inch radial size along with a 17-inch alternative. That makes wheel confirmation especially important, and the 17-inch size also opens the door to sidewall styling choices that are not present in the larger fitments.
The 2019 Audi A3 Quattro Prestige Cabriolet uses 18-inch and 19-inch radial tire sizes rather than the 17-inch fitment seen on some Premium versions. Tire selection comes down to matching the installed wheel diameter first, then narrowing choices by brand and tire series.
The 2019 Audi A3 Quattro Prestige Sedan shares the same 18-inch and 19-inch radial fitment pattern used by other higher sedan trims. Buyers should confirm the wheel setup before ordering, then compare the available blackwall performance-oriented options in the matching size.
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 2019 Audi A3 Quattro?
The 2019 Audi A3 Quattro uses three primary tire sizes: 225/45R17, 225/40R18, and 235/35R19. All three are radial fitments, but they do not apply to every version of the car. Premium sedan and cabriolet versions use 17-inch or 18-inch fitments, while Premium Plus and Prestige versions commonly use 18-inch or 19-inch fitments.
The right choice depends on the exact sub-model and the wheel diameter currently on the car. A quick check of the tire sidewall or wheel size is the easiest way to confirm whether the A3 Quattro is set up for 17-, 18-, or 19-inch tires before comparing brands, series, and sidewall treatments.
What size rim does a 2019 Audi A3 Quattro use?
A 2019 Audi A3 Quattro can use 17-inch, 18-inch, or 19-inch rims, depending on the tire size and sub-model. The 225/45R17 fitment uses a 17-inch rim, the 225/40R18 fitment uses an 18-inch rim, and the 235/35R19 fitment uses a 19-inch rim.
Rim diameter needs to match the tire size exactly, so the first check is always the wheel itself rather than the model name alone. The car may also have been changed by a previous owner, so verifying the actual wheel setup helps prevent ordering a correct tire size for the wrong rim diameter.
Do all 2019 Audi A3 Quattro sub-models use the same tire size?
No. Every 2019 Audi A3 Quattro sub-model shares the 225/40R18 radial size as one fitment, but the second size varies. Premium sedan and Premium cabriolet versions use 225/45R17 as their other fitment, while Premium Plus and Prestige sedan and cabriolet versions use 235/35R19.
That split makes the exact trim and wheel package important. Two A3 Quattro cars from the same year can both be correct while wearing different rim diameters, so it is smart to confirm the sub-model and inspect the wheel and sidewall before narrowing the search to a specific tire series or sidewall appearance.
Choosing the Right Tire
What should I consider when choosing a tire for a 2019 Audi A3 Quattro?
Start with the correct primary tire size for the car's sub-model and installed wheel diameter, since the 2019 Audi A3 Quattro uses 17-, 18-, and 19-inch radial fitments. After that, compare construction details within the proper size, including brand, tire series, sidewall treatment, and any available rim-width or load-capacity specifications.
The best comparison is between tires in the same size, not across different wheel diameters. It also helps to think about how the car is used, whether that is regular street driving, seasonal use, or a more appearance-focused setup, then check wheel compatibility and tire clearance before making a final selection.
What sidewall styles are available for 2019 Audi A3 Quattro tires?
Most 2019 Audi A3 Quattro tire options use a blackwall sidewall, especially in 225/40R18 and 235/35R19. The 225/45R17 size adds more visible styling choices with Pro-Trac Street Pro III options available in raised white letter and redline form alongside blackwall tires from BFGoodrich and Nitto.
Sidewall style changes appearance more than fitment, but it still needs to be chosen within the correct tire size. A buyer who wants a more traditional or custom visual touch may focus on 225/45R17, while owners staying with 18-inch or 19-inch fitments will usually be comparing blackwall performance-oriented choices.
What brands offer tires for the 2019 Audi A3 Quattro?
Tires for the 2019 Audi A3 Quattro are available from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears across all three primary sizes with several g-Force series, Nitto covers the fitment range with NT555 G2 offerings, and Pro-Trac appears in the 225/45R17 size through the Street Pro III line.
Brand is only one part of the decision. It still makes sense to compare the exact tire series, sidewall style, and wheel compatibility within the correct size, since one brand may offer more appearance variety in 17-inch fitment while another may only be available in blackwall form for the larger wheel packages.
Restoration & Appearance
Which tire should I choose for a period-style 2019 Audi A3 Quattro?
A period-style approach on a 2019 Audi A3 Quattro still begins with the correct modern radial size for the sub-model and wheel diameter. Since this is a contemporary vehicle, the appearance decision is usually about staying true to the car's original wheel package and choosing a tire series and sidewall presentation that does not look out of place.
The most restrained look will usually come from blackwall tires in the factory-style wheel diameter already on the car. Owners seeking a more personalized appearance may notice the 225/45R17 fitment offers redline and raised white letter choices, but those are styling decisions rather than proof of exact original-delivery appearance.
How does tire construction affect the appearance of a restored 2019 Audi A3 Quattro?
On a 2019 Audi A3 Quattro, construction is straightforward because the primary fitments are all modern radial tires. That means the visual differences come less from bias-ply versus radial shape and more from tire profile, wheel diameter, sidewall treatment, and the character of the tire series chosen within the correct size.
An A3 Quattro kept on its proper 17-, 18-, or 19-inch setup will usually look most coherent when the tire profile matches that wheel package. Owners aiming for a restoration-minded presentation should confirm the exact sub-model and current wheels first, then use appearance details like blackwall, redline, or raised white letter more selectively.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Audi A3 Quattro?
Yes. A 2019 Audi A3 Quattro may start with one of three correct radial sizes, but aftermarket wheels, lowering springs, suspension changes, spacers, or body modifications can alter what actually clears the car. That matters most when switching between 17-, 18-, and 19-inch wheel setups or when using wider wheels than the car originally carried.
The safest approach is to inspect the wheel diameter and width already on the car, then check steering lock, fender clearance, and suspension travel before choosing a tire. A modified A3 Quattro should be treated as its actual setup, not only by year and model name, because those changes can affect fitment even when the tire size looks close.
What should I inspect before driving a 2019 Audi A3 Quattro on new tires?
Before road use, inspect the wheel diameter, wheel condition, valve stems, and the tire sidewalls to make sure the installed size matches the car's 17-, 18-, or 19-inch setup. It also helps to confirm proper inflation, look for shipping or mounting damage, and make sure the tires clear the suspension and fenders through a full steering sweep.
A short local drive is a good way to confirm there is no rubbing, vibration, or unusual pull before putting more miles on the car. Alignment condition also matters on a modern Audi, since uneven settings can affect tire wear quickly, especially on lower-profile fitments like 225/40R18 and 235/35R19.
How often should tires on a 2019 Audi A3 Quattro be inspected?
Tires on a 2019 Audi A3 Quattro should be checked regularly, not just when tread looks worn. A visual inspection every month and before longer drives helps catch uneven wear, cuts, punctures, sidewall damage, or pressure loss early, which is especially useful on low-profile radial sizes where changes in condition can become noticeable quickly.
It is also smart to inspect the tires any time the car has hit a pothole or curb, or whenever steering feel changes. Keeping an eye on tread wear patterns can reveal alignment or suspension issues, and regular pressure checks help the correct 17-, 18-, or 19-inch fitment deliver the behavior the car was set up to use.
