The 2023 Audi A4 Quattro sits in the modern sport-sedan tradition, blending all-wheel-drive confidence with the clean, understated character that has defined the A4 line for years. For many owners, tire choice is a big part of preserving that balance between everyday composure and sharper road feel. This model uses radial tire fitments in 225/50R17, 245/40R18, and 245/35R19, depending on sub-model and wheel package. Available choices range from blackwall performance radials to redline and raised white letter options in select 18-inch sizing. The key is matching the correct size to the exact trim and wheel diameter before comparing brand, series, and appearance preferences.
Which Tire Size Is Right for The 2023 Audi A4 Quattro
The 2023 Audi A4 Quattro uses three primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. Since these fitments span 17-inch, 18-inch, and 19-inch rims, the first step is confirming the wheel size currently on the car. After that, the decision shifts to selecting the right radial tire within that size, including performance-oriented series and, in some 18-inch applications, different sidewall presentations.
A 225/50R17 tire is a metric radial size with a 225-millimeter section width, a 50-series aspect ratio, and fitment on a 17-inch rim. On the 2023 Audi A4 Quattro, this size supports a modern radial setup with a little more sidewall than the larger-wheel alternatives. Available choices include BFGoodrich and Nitto blackwall tires across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, and NT555 G2. This size is worth choosing when the car is equipped with the 17-inch wheel package and the goal is to stay aligned with that original wheel diameter and tire profile.

A 245/40R18 tire is a metric radial size that uses a 245-millimeter section width, a 40-series aspect ratio, and an 18-inch rim. For the 2023 Audi A4 Quattro, this is the most widely shared fitment across the covered sub-model range and represents the central tire size to verify first on many cars. Product choices include blackwall performance radials from BFGoodrich, Nitto, and M&H Racemaster, along with Pro-Trac options in redline and RWL sidewall styles. This size deserves close attention because it combines broad sub-model usage with the widest visible range of product character and appearance.

A 245/35R19 tire is a metric radial size with a 245-millimeter section width, a 35-series aspect ratio, and fitment on a 19-inch rim. On the 2023 Audi A4 Quattro, this size belongs to specific higher-wheel configurations rather than every sub-model. Available tires include blackwall radial choices from BFGoodrich and Nitto in series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This fitment should be evaluated when the car already has the 19-inch wheel package and the goal is to keep the correct low-profile relationship between tire and wheel.
Tire fitment on the 2023 Audi A4 Quattro varies by sub-model and, in some cases, by wheel package within the same trim. Checking the exact trim and horsepower version matters because the covered range includes 17-inch, 18-inch, and 19-inch tire sizes.

These FAQs focus on the exact tire sizes used on the 2023 Audi A4 Quattro, how fitment changes by trim and wheel diameter, and what to compare when choosing among the available radial tire options.
Tire Size & Fitment
What tire size fits a 2023 Audi A4 Quattro?
The 2023 Audi A4 Quattro uses 225/50R17, 245/40R18, or 245/35R19 radial tires. The correct size depends on the exact sub-model and wheel package, so there is not one universal fitment across every covered version of the car.
The fastest way to narrow it down is to confirm the wheel diameter currently on the vehicle and then match that to the correct size. A 17-inch wheel uses 225/50R17, an 18-inch wheel uses 245/40R18, and a 19-inch wheel uses 245/35R19, but modified cars should also be checked for non-original wheel changes.
What size rim does a 2023 Audi A4 Quattro use?
The 2023 Audi A4 Quattro uses 17-inch, 18-inch, or 19-inch rims depending on sub-model and wheel setup. Those rim diameters correspond to the three primary tire sizes: 225/50R17, 245/40R18, and 245/35R19.
Wheel diameter should be confirmed before selecting a tire because these sizes are not meant for the same rim. Once the diameter is verified, it also helps to compare the wheel width against the tire's intended rim-width range, especially if the car has aftermarket wheels or a trim package different from what the current owner expects.
Why does the 2023 Audi A4 Quattro have more than one tire size?
The 2023 Audi A4 Quattro has more than one tire size because fitment changes with sub-model and wheel package. Some trims use a single 18-inch setup, while others can appear with either a 17-inch or 18-inch package, or with 18-inch and 19-inch fitments.
That means the right tire is determined by the exact version of the car and the wheels actually installed on it, not by model name alone. Before comparing brands or tread styles, check the trim, horsepower designation, and the wheel diameter on the vehicle so the tire search stays centered on the correct fitment.
Choosing the Right Tire
What should I consider when choosing a tire for a 2023 Audi A4 Quattro?
Start with the correct size for the exact car: 225/50R17, 245/40R18, or 245/35R19. From there, compare construction, rim-width suitability where stated, load figures where available, tire series, and whether the goal is everyday street use, a more performance-focused feel, or a distinct visual presentation.
The 245/40R18 category offers the broadest visible spread of choices, so that size especially benefits from careful comparison. It helps to match the tire to how the car is driven and how it is equipped, since a stock wheel package, an altered wheel setup, or a style-driven choice such as redline or RWL can change what makes sense.
What sidewall styles are available for 2023 Audi A4 Quattro tires?
Blackwall is the most common sidewall style across the available 2023 Audi A4 Quattro tire options. In 245/40R18, there are also Pro-Trac Street Pro III choices with redline and RWL sidewalls, giving that size a broader appearance range than the 17-inch and 19-inch fitments shown here.
Sidewall style does not replace the need for correct sizing, so the first check is still wheel diameter and the tire size tied to that setup. Once fitment is confirmed, sidewall treatment becomes an appearance decision, with blackwall suiting a more understated look and redline or raised white letter creating a more pronounced visual statement on the car.
What brands offer tires for the 2023 Audi A4 Quattro?
Available tire brands for the 2023 Audi A4 Quattro include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac. Brand availability varies by size, with BFGoodrich and Nitto appearing across all three primary fitments and M&H Racemaster and Pro-Trac appearing in the 245/40R18 range.
Brand choice is only one part of the decision. It still makes sense to compare the exact tire series, sidewall style, rim-width guidance where stated, and the intended use of the car, because two tires from different brands may serve very different goals even when they share the same nominal size.
Restoration & Appearance
Which tire should I choose for a period-style 2023 Audi A4 Quattro?
A period-style approach on a 2023 Audi A4 Quattro starts with staying in the correct tire size for the car's actual wheel package. Since this is a modern Audi with radial-only fitments, the visual choice is less about vintage construction and more about selecting a tire series and sidewall presentation that suits the car's intended look.
For a cleaner OEM-inspired presentation, blackwall options keep the appearance understated. If the car uses 245/40R18 and the goal is a more customized look, redline or RWL options are available, but buyers focused on preserving the original character of the car should compare those choices against the vehicle's build details and current wheel setup.
Does correct tire fitment matter for a 2023 Audi A4 Quattro restoration or appearance build?
Correct tire fitment matters because the 2023 Audi A4 Quattro uses three distinct radial sizes tied to different wheel diameters. Choosing the wrong size can change the car's stance, the sidewall profile it presents, and the overall balance between wheel and tire that defines the finished appearance.
Appearance builds often focus on visible details, but fitment still comes first. A 17-inch, 18-inch, or 19-inch wheel setup should keep the tire size intended for that rim, and any custom wheel change should be checked carefully so the finished look does not come at the expense of proper clearance, wheel compatibility, or overall visual proportion.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Audi A4 Quattro?
Yes, modifications can affect tire fitment on a 2023 Audi A4 Quattro. Aftermarket wheels, changes in wheel width, suspension lowering, and body or alignment changes can all influence whether the original 225/50R17, 245/40R18, or 245/35R19 fitment still makes sense on the car.
Even when the tire size itself is correct for the model, a modified setup can change steering clearance and the relationship between the tire and the fender. Any A4 Quattro with non-original wheels or suspension should be measured carefully before replacement so the new tire matches the actual wheel package and available space on the vehicle.
What should I inspect before driving a 2023 Audi A4 Quattro on new tires?
Before driving a 2023 Audi A4 Quattro on new tires, inspect the wheel diameter and width, confirm the tire size matches the wheel package, and check that each tire is inflated properly. It also helps to look over the wheels themselves for damage and make sure the tires have consistent seating and no visible issues.
A short road test should be followed by another visual inspection for rubbing, unusual wear, or air loss. Cars that have sat for a long period or have recent suspension work deserve extra attention, since worn components, alignment issues, or prior wheel changes can affect how a fresh set of tires behaves once the car is back on the road.
How often should tires on a 2023 Audi A4 Quattro be inspected?
Tires on a 2023 Audi A4 Quattro should be inspected regularly, not just when tread looks low. Frequent checks for pressure loss, cuts, bulges, uneven wear, and sidewall damage are especially worthwhile on a modern sport sedan where tire profile and wheel diameter have a strong effect on ride quality and handling feel.
A practical routine is to inspect them before longer drives and any time the car feels different on the road. Vehicles with lower-profile 18-inch or 19-inch setups deserve close attention to wheel condition as well, and any sign of rubbing or irregular wear should prompt a review of alignment, suspension condition, and whether the current wheels match the intended fitment.
