2017 Audi A3 Tires

The 2017 Audi A3 uses three primary tire sizes: 225/45R17, 225/40R18, and 235/35R19. All are radial sizes, but they do not apply across every version of the car, so the correct fitment depends on the exact sedan or cabriolet trim and the wheel diameter installed on that vehicle.

The practical first step is checking the actual wheels on the car rather than assuming every A3 uses the same setup. A Premium sedan or Premium cabriolet may use 17-inch or 18-inch tires, while several Premium Plus and Prestige models use 18-inch or 19-inch fitments. Matching the tire to the current wheel diameter is essential before comparing brands or sidewall styles.

A 2017 Audi A3 can use 17-inch, 18-inch, or 19-inch rims, depending on the sub-model and tire size. The three primary combinations are 225/45R17 on a 17-inch rim, 225/40R18 on an 18-inch rim, and 235/35R19 on a 19-inch rim.

That range means rim diameter should be confirmed before ordering tires, especially on cars that may have had wheel changes over time. Reading the current tire sidewall and checking the wheel itself helps prevent mixing a 17-inch, 18-inch, or 19-inch tire with the wrong rim. Once rim diameter is verified, the buyer can narrow the choice to the right size and series.

The 2017 Audi A3 has more than one tire size because fitment varies by sub-model and wheel package. Premium sedan and Premium cabriolet versions can use 225/45R17 or 225/40R18, while Premium Plus and Prestige sedan and cabriolet versions use 225/40R18 or 235/35R19.

That variation means tire selection starts with identifying the exact trim and confirming the wheels currently on the car. Two A3s from the same model year can require different tires even when they look similar at a glance. Once the correct size is established, the next comparison points are brand, tire series, blackwall versus styled sidewall options, and any relevant rim-width specification.

Start with the exact tire size and wheel diameter used on the car, because a 2017 Audi A3 may require 225/45R17, 225/40R18, or 235/35R19. From there, compare radial tire options by construction details, rim-width suitability where stated, sidewall appearance, and the kind of driving the car actually sees.

A buyer who wants a straightforward modern look may stay with blackwall tires, while someone shopping in 225/45R17 has additional raised white letter and redline choices. It also helps to compare tire series across BFGoodrich, Nitto, and Pro-Trac without assuming every tire in the same size has the same character. The best approach is matching the tire to the car’s existing wheel setup and intended use.

Most available 2017 Audi A3 tire options use a blackwall sidewall, especially in 225/40R18 and 235/35R19. In 225/45R17, the range expands to include blackwall as well as raised white letter and redline sidewall treatments through the Pro-Trac Street Pro III line.

Sidewall style does not change the basic requirement to use the correct size for the car, but it does affect the overall presentation. A blackwall keeps the look understated and contemporary, while raised white letter or redline gives a more customized appearance. Before choosing for style alone, confirm that the 17-inch fitment is actually the one on the A3, since those alternate sidewalls are not offered across every size.

Tires for the 2017 Audi A3 are available from BFGoodrich, Nitto, and Pro-Trac, depending on the size. BFGoodrich appears across all three primary sizes, Nitto is offered in all three sizes as well, and Pro-Trac options appear in 225/45R17 with Street Pro III raised white letter and redline versions.

Brand comparison matters most after the correct fitment is confirmed, because the available selection changes with wheel diameter. An A3 on 17-inch wheels has the widest appearance range, while 18-inch and 19-inch choices stay focused on blackwall radial performance-oriented options. Looking at tire series, rim-width specifications where available, and sidewall style will usually be more helpful than focusing on brand name alone.

A period-style approach on a 2017 Audi A3 usually means staying with the correct original size category for the car’s current wheel setup rather than changing diameters for appearance alone. Since this A3 is a modern radial-fitment vehicle, the closest visual starting point is typically a blackwall tire in 225/45R17, 225/40R18, or 235/35R19, depending on the trim and wheels.

Appearance choices become more noticeable once size is settled. A blackwall tends to preserve the clean, contemporary look associated with the A3, while select 225/45R17 options add redline or raised white letter styling for a more customized presentation. Buyers focused on preserving the car’s original visual character should also compare the existing wheel design and overall stance before making a final choice.

On a 2017 Audi A3, construction does not create a bias-ply-versus-radial appearance decision because the primary fitments are radial across the board. The visual difference comes more from size, profile, wheel diameter, and sidewall treatment than from a construction change between vintage and modern tire types.

That makes the restoration-oriented decision more about keeping the tire proportion appropriate to the wheel package already on the car. A 17-inch setup with 225/45R17 leaves room for blackwall, raised white letter, or redline choices, while the 18-inch and 19-inch fitments stay within a blackwall presentation. Keeping the size matched to the proper trim helps the car retain a balanced and believable finished look.

Yes, modifications can affect tire fitment on a 2017 Audi A3, even when the tire size itself is commonly used on the model. Aftermarket wheels, suspension changes, altered ride height, or body changes can influence how a 225/45R17, 225/40R18, or 235/35R19 tire sits within the wheelwell and how much clearance remains during steering and suspension travel.

A modified A3 should be checked for wheel diameter, wheel width, and clearance before a replacement tire is chosen simply by size. It is also wise to inspect for rubbing marks, limited steering clearance, or unusually tight fender space. Those checks matter most on lower-profile 18-inch and 19-inch combinations, where even a correct nominal size still needs to suit the car’s actual setup.

Before driving a 2017 Audi A3 on new tires, inspect the wheel diameter, confirm the tire size matches the car’s trim and wheel package, and check that inflation is appropriate for the installation. It is also smart to look over the wheels for damage and make sure there is no interference at the fenders, struts, or steering components.

A short, careful road test can reveal vibration, rubbing, or uneven response that deserves attention before normal use. Tire age on the removed set is also worth noting, since an A3 that sees intermittent use may show cracking or other condition issues long before the tread appears worn out. Continued pressure checks and periodic visual inspection help protect the new set over time.

Tires on a 2017 Audi A3 should be inspected regularly, not only when tread looks low. A visual check for cracking, bulges, cuts, irregular wear, and air loss is a good habit on any modern performance-oriented fitment, especially with lower-profile sizes like 225/40R18 and 235/35R19 where wheel and sidewall condition are easy to overlook.

Monthly pressure checks are a practical routine, and a closer inspection before longer trips is worthwhile even on a daily-driven A3. Cars that sit for stretches can develop flat spotting, pressure loss, or age-related sidewall issues despite limited mileage. Catching those problems early helps preserve ride quality and keeps the buyer focused on condition, not just the printed tire size.
