The 2023 Audi A3 Quattro brings compact luxury, turbocharged responsiveness, and all-wheel-drive confidence into a modern sport sedan package that still rewards careful chassis setup. It sits in a segment where wheel and tire choice strongly influence both appearance and everyday road feel. For this exact model, tire fitment centers on two radial sizes, 225/45R17 and 225/40R18, so the first step is confirming which wheel diameter is on the car. Available choices then branch into different tire series, brands, and sidewall treatments. That makes this page most useful for owners balancing original-style sizing, replacement needs, and any wheel or suspension changes already made to the car.
Which Tire Size Is Right for The 2023 Audi A3 Quattro
The 2023 Audi A3 Quattro uses two primary tire sizes, and the difference comes down to wheel diameter rather than a change from bias-ply to radial construction. Both 225/45R17 and 225/40R18 are radial fitments, and both appear across Premium and Premium Plus trims. Before choosing a tire, confirm whether the car is riding on 17-inch or 18-inch wheels, especially if it has already been fitted with alternate wheels.
The 225/40R18 size code identifies a metric radial tire with a 225-millimeter section width, a 40-series aspect ratio, and fitment for an 18-inch wheel. On the 2023 Audi A3 Quattro, this size supports the larger-wheel setup while keeping a relatively short sidewall that suits the car’s modern sport-sedan character. Available choices include BFGoodrich and Nitto offerings in series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2, all in blackwall form. This size is the one to evaluate when the car already wears 18-inch wheels and the goal is to stay with that wheel-and-tire proportion.
The 225/45R17 code describes a metric radial tire that is 225 millimeters wide, uses a 45-series profile, and mounts on a 17-inch rim. For the 2023 Audi A3 Quattro, it serves the 17-inch wheel setup and carries the same modern radial construction as the 18-inch alternative. Product choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, raised white letter, and redline sidewall treatments available across several series. This size deserves attention when keeping the factory wheel diameter already on the car or when appearance preferences matter as much as straightforward replacement sizing.
Fitment is straightforward across the covered 2023 Audi A3 Quattro sub-models because both trims use the same two primary tire sizes. Checking the exact sub-model still helps confirm whether the car remains on its original wheel diameter or has been changed to another setup.

2023 Audi A3 Quattro Premium
The 2023 Audi A3 Quattro Premium uses the same 225/45R17 and 225/40R18 radial sizing pattern seen across this model range. Tire selection therefore comes down to confirming the actual wheel diameter on the car, then comparing available brands, tire series, and sidewall presentations within that size.
The 2023 Audi A3 Quattro Premium Plus also uses 225/45R17 and 225/40R18 radial tires. That keeps fitment simple, but it remains important to verify whether the car is on 17-inch or 18-inch wheels before choosing among the available blackwall, redline, or raised white letter 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.
Best 2023 Audi A3 Quattro Tires for Sale

Tire Size & Fitment
What tire size fits a 2023 Audi A3 Quattro?
The 2023 Audi A3 Quattro uses two primary tire sizes: 225/45R17 and 225/40R18. Both are radial fitments, and both appear on Premium and Premium Plus versions of the car, so the main difference is the wheel diameter rather than a trim-specific change in tire construction.
Choosing between them starts with the wheel that is actually on the car today. A3 Quattro sedans that have had wheel swaps, seasonal wheel sets, or other changes should be checked at the rim before ordering tires, since a 17-inch tire and an 18-inch tire are not interchangeable just because they share the same 225-millimeter width.
What size rim does a 2023 Audi A3 Quattro use?
A 2023 Audi A3 Quattro uses either a 17-inch or 18-inch rim, depending on which tire size is on the car. The 225/45R17 tire mounts on a 17-inch wheel, while the 225/40R18 tire mounts on an 18-inch wheel.
That rim-diameter check should happen before comparing brands or tire series, because it determines the correct fitment path immediately. Wheel width also matters once the tire size is narrowed down, especially if the car has aftermarket wheels, since different products within the same nominal size can carry different recommended rim-width ranges.
Do all 2023 Audi A3 Quattro sub-models use the same tire size?
Premium and Premium Plus versions of the 2023 Audi A3 Quattro share the same two tire sizes: 225/45R17 and 225/40R18. In practical terms, that means trim level alone does not decide the tire size; the wheel diameter on the individual car does.
This makes sub-model fitment easier than on vehicles where each trim has its own size, but it still leaves one important check. Look at the existing tire or wheel before selecting a replacement, particularly if the car has seen dealer-installed accessories, a second wheel package, or prior owner modifications.
Choosing the Right Tire
What should I consider when choosing a 225/45R17 or 225/40R18 tire for a 2023 Audi A3 Quattro?
Start with the correct size for the wheel already on the car, since the 2023 Audi A3 Quattro uses either 225/45R17 or 225/40R18. From there, compare construction details that matter within that size, including rim-width compatibility, load figures where stated, tire weight, brand, and the tire series that best matches how the car is driven.
Appearance can also shape the decision, especially in 225/45R17 where blackwall, raised white letter, and redline options are available. Owners trying to keep a contemporary look may lean toward blackwall, while those after a more distinctive presentation may compare the Pro-Trac sidewall treatments after confirming that the wheel and overall setup remain suitable.
What sidewall styles are available for 2023 Audi A3 Quattro tires?
Sidewall choice depends on the tire size. In 225/40R18, the available options are blackwall. In 225/45R17, the range expands to blackwall, raised white letter, and redline, giving the smaller-diameter setup more visible appearance variety than the 18-inch fitment.
That makes sidewall style a real part of the buying decision rather than a minor detail. A blackwall tire keeps the presentation understated and modern, while redline or raised white letter styling adds a more customized look. The key is to choose the sidewall treatment only after confirming the correct 17-inch or 18-inch wheel size on the car.
What brands offer tires for the 2023 Audi A3 Quattro?
Tire choices for the 2023 Audi A3 Quattro include BFGoodrich, Nitto, and Pro-Trac, depending on size. BFGoodrich appears in both 225/45R17 and 225/40R18 with several g-Force series, Nitto offers the NT555 G2 in both sizes, and Pro-Trac appears in 225/45R17 with Street Pro III options.
Brand is only one part of the comparison. It helps to look at the full tire series, the sidewall style, and the wheel-width specifications for the exact tire under consideration, since those details influence how well a particular product aligns with the car’s current wheels and the owner’s preferred look.
Restoration & Appearance
Which tire should I choose for a period-style 2023 Audi A3 Quattro?
A period-style approach on a 2023 Audi A3 Quattro usually means keeping the original sizing relationship intact and selecting a sidewall treatment that suits the car’s intended presentation. Since this model uses modern radial sizes only, the visual decision is less about vintage construction and more about whether the car should look understated, sport-oriented, or slightly customized.
Blackwall options preserve the cleanest factory-inspired appearance, while 225/45R17 also opens the door to redline or raised white letter styling for a more individualized look. The right choice depends on the wheel diameter already fitted and how closely the owner wants to stay with a restrained contemporary presentation.
Does correct tire fitment matter for a 2023 Audi A3 Quattro restoration or appearance build?
Correct tire fitment matters because the 2023 Audi A3 Quattro relies on a precise relationship between wheel diameter, sidewall height, and overall stance. Using the wrong size can change how the wheel opening is filled, alter the visual balance of the car, and complicate clearance even before road manners are considered.
Appearance builds benefit from treating tire size and sidewall style as part of the overall design rather than an afterthought. Matching 225/45R17 or 225/40R18 to the actual wheel on the car keeps the proportions consistent, and then the visual character can be tuned through blackwall, redline, or raised white letter options where available.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Audi A3 Quattro?
Yes. Modifications can affect tire fitment on a 2023 Audi A3 Quattro even when the tire size itself looks correct on paper. Aftermarket wheels, changes in wheel width or offset, suspension lowering, alignment changes, and body modifications can all influence clearance at the fender, strut, and steering range.
A car that has been altered should be checked more carefully than one on its original wheel setup. Verify rim diameter first, then confirm wheel width and observe available clearance with the steering turned and the suspension loaded, since either 225/45R17 or 225/40R18 can become problematic if the surrounding hardware has changed.
What should I inspect before driving a 2023 Audi A3 Quattro on new tires?
Inspect the wheel size, tire pressure, valve stems, lug torque, and visible clearance before regular driving. It also helps to look over the suspension and alignment condition, because fresh tires can quickly reveal existing wear issues that were less obvious on older tires.
After the first few drives, recheck pressure and watch for rubbing, vibration, or uneven wear patterns. A 2023 Audi A3 Quattro fitted with the correct 225/45R17 or 225/40R18 size should still be evaluated as a complete wheel-and-tire package, especially if the car uses non-original wheels or has recently had chassis work performed.
How often should tires on a 2023 Audi A3 Quattro be inspected?
Tires on a 2023 Audi A3 Quattro should be inspected regularly rather than waiting for obvious wear. A quick visual check during routine cleaning or fueling can catch low pressure, cuts, bulges, or abnormal tread wear early, and a more deliberate inspection should happen before longer drives or seasonal changes.
Owners should pay particular attention when the car has low-profile 225/40R18 tires, since shorter sidewalls make wheel damage and impact-related issues worth watching closely. Any sign of repeated air loss, uneven shoulder wear, or fresh contact marks deserves follow-up before continued use, even when the tire size itself is correct.
