The 2020 Audi A3 Quattro sits in the modern compact luxury sport-sedan category, blending Audi’s all-wheel-drive character with a sharper, more athletic road feel than many everyday commuter cars. Buyers usually come to this platform looking for responsive handling, clean factory-style proportions, and a tire setup that matches the car’s precise stance. Tire fitment centers on two radial sizes, 225/40R18 and 235/35R19, with sizing tied to sub-model and wheel package. Available choices stay performance-focused, with blackwall designs from BFGoodrich and Nitto across several sport-oriented series. The key is matching the exact wheel diameter and sub-model before comparing tire series, load specifications, and overall driving intent.
Which Tire Size Is Right for The 2020 Audi A3 Quattro
The 2020 Audi A3 Quattro uses two primary tire sizes, and the first step is confirming both the exact sub-model and the wheel diameter on the car. Fitment is radial in both cases, but 225/40R18 belongs on 18-inch wheels while 235/35R19 belongs on 19-inch wheels, so the real decision starts with the wheel and then moves to tire series, brand, and specification details.
225/40R18 is a modern metric radial size that identifies a 225-millimeter nominal section width, a 40-series aspect ratio, radial construction, and fitment for an 18-inch rim. On the 2020 Audi A3 Quattro, this size supports the car’s contemporary sport-sedan balance while staying within the correct radial construction. Available choices include BFGoodrich and Nitto blackwall tires across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This size is the one to evaluate when the car is equipped with 18-inch wheels and you want to compare performance-oriented options within that exact fitment.
235/35R19 is a modern metric radial size with a 235-millimeter nominal section width, a 35-series profile, radial construction, and fitment for a 19-inch rim. For the 2020 Audi A3 Quattro, it serves as the larger-wheel fitment and should be selected only on cars actually using 19-inch wheels. Product choices in this size include blackwall performance tires from Nitto and BFGoodrich, including NT555 G2 and g-Force Phenom T/A. This size is worth considering when the vehicle’s wheel package calls for the 19-inch setup and you want to preserve the intended wheel-to-tire relationship.
Sub-model fitment matters on the 2020 Audi A3 Quattro because tire size is not the same across every covered version. The Premium uses one radial size, while the Premium Plus can use either 18-inch or 19-inch fitment, making the exact sub-model and wheel setup the first things to confirm.

Tire Size & Fitment
What tire size fits a 2020 Audi A3 Quattro?
The 2020 Audi A3 Quattro uses either 225/40R18 or 235/35R19, both in radial construction. The Premium uses 225/40R18, while the Premium Plus can use 225/40R18 or 235/35R19 depending on the wheel setup on the car.
The most important check is the actual wheel diameter before choosing a tire. An 18-inch tire and a 19-inch tire are not interchangeable, even when the overall proportions look similar, so the wheel and sub-model should be confirmed first and then matched to the correct tire series and rim-width requirements.
What size rim does a 2020 Audi A3 Quattro use?
A 2020 Audi A3 Quattro uses either an 18-inch rim or a 19-inch rim, depending on the tire size fitted to the car. The 225/40R18 size goes with an 18-inch wheel, and the 235/35R19 size goes with a 19-inch wheel.
Wheel diameter is the first fitment checkpoint because it determines which tire size category even belongs on the vehicle. After that, wheel width still matters, especially when comparing specific performance tires, so it is worth checking the actual wheel dimensions on the car rather than relying only on trim name or appearance.
Do all 2020 Audi A3 Quattro sub-models use the same tire size?
No, all 2020 Audi A3 Quattro sub-models do not use the same tire size. The Premium uses 225/40R18, while the Premium Plus can be fitted with either 225/40R18 or 235/35R19.
That difference means tire selection is not just a matter of model year and make. The safest path is to confirm the exact sub-model and then verify the wheels currently on the vehicle, especially if it has been changed from its original wheel package or fitted with aftermarket wheels at some point.
Choosing the Right Tire
What should I consider when choosing a tire for a 2020 Audi A3 Quattro?
Start with the correct primary size for the car: 225/40R18 or 235/35R19. From there, the main factors are wheel diameter, tire series, construction consistency, rim-width compatibility, and whether the tire’s overall character matches how the Audi is driven.
A3 Quattro buyers often compare sport-oriented road manners more than appearance, since the available products are blackwall radials. It also helps to review specification differences such as maximum load figures where given, along with wheel width and the vehicle’s actual setup, so the tire choice supports both fitment and intended use.
What brands offer tires for the 2020 Audi A3 Quattro?
BFGoodrich and Nitto offer tires for the 2020 Audi A3 Quattro in the covered fitments. Depending on size, options include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and the Nitto NT555 G2.
Brand alone should not make the decision. It is smarter to narrow the search by the exact tire size first, then compare the available series within that size, paying attention to wheel-width fitment, load details where they are stated, and how performance-focused or all-season-oriented the tire appears to be.
What tire series are available for the 2020 Audi A3 Quattro?
The available tire series for the 2020 Audi A3 Quattro include g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2. Those series are spread across the 225/40R18 and 235/35R19 fitments rather than appearing equally in both sizes.
Series matters because it helps distinguish the type of performance tire you are comparing within the correct fitment. Once the wheel diameter is confirmed, looking at the series can help narrow the field by intended character, while rim-width specifications and other product details help determine whether a given option suits the car’s wheel setup.
Restoration & Appearance
Does correct tire fitment matter for a 2020 Audi A3 Quattro restoration or factory-style presentation?
Yes, correct tire fitment matters because the 2020 Audi A3 Quattro uses specific low-profile radial sizes tied to its wheel package. Using the proper 225/40R18 or 235/35R19 size helps preserve the car’s intended stance, wheel-to-tire proportion, and overall late-model Audi appearance.
A factory-style presentation on a modern vehicle usually depends more on matching the original size format and wheel diameter than on decorative sidewall treatment. Since the available products here are blackwall radials, the key visual decision is keeping the right size and profile for the car rather than chasing a vintage-style look.
How does tire construction affect the appearance of a restored 2020 Audi A3 Quattro?
Tire construction is straightforward on the 2020 Audi A3 Quattro because the covered fitments are radial. That means the appearance question is less about bias-ply versus radial styling and more about preserving the modern low-profile proportions created by 225/40R18 or 235/35R19 on the correct wheel diameter.
Keeping the correct radial size helps the car retain the clean, contemporary profile expected of this generation A3. A mismatched aspect ratio or wheel diameter can alter that presentation quickly, so buyers aiming for a restoration-oriented or factory-style look should confirm the wheel package first and then stay within the proper size family.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Audi A3 Quattro?
Yes, modifications can affect tire fitment on a 2020 Audi A3 Quattro. Aftermarket wheels, suspension changes, lowering, spacer use, or body alterations can all change the clearance relationship around a 225/40R18 or 235/35R19 tire.
Even when the tire size itself is correct for the model, a changed wheel width or offset can alter fender, strut, or steering clearance. That is why the actual wheel dimensions and the car’s current suspension setup should be checked before selecting a replacement tire, especially on vehicles that no longer retain stock wheels.
What should I inspect before driving a 2020 Audi A3 Quattro on new tires?
Before driving a 2020 Audi A3 Quattro on new tires, inspect wheel condition, confirm the correct tire size, and check inflation pressure. It is also wise to look over tread seating, valve stems, and the visible sidewalls for any damage that could affect safe road use.
A short initial check for rubbing during full steering lock and normal suspension movement is worthwhile, especially if the car has nonstock wheels or previous modifications. After a few miles, recheck pressure and make sure the tires are wearing evenly, since alignment or suspension issues can show up quickly on low-profile performance fitments.
How often should tires on a 2020 Audi A3 Quattro be inspected?
Tires on a 2020 Audi A3 Quattro should be inspected regularly, not just when tread looks low. Low-profile radial tires can reveal pressure loss, edge wear, cuts, bulges, or impact damage sooner than many taller sidewall tires, so routine visual checks are important.
A practical habit is to inspect them during pressure checks and before longer drives. Cars that see limited mileage still need attention, because age, storage conditions, and long idle periods can affect tire condition even when tread depth remains good, and early detection is especially useful on performance-oriented wheel and tire packages.
