The 2023 Audi A5 Quattro blends modern Audi coupe and cabriolet design with the all-weather confidence that has long defined Quattro-badged grand touring cars. It sits in a part of the market where styling, road manners, and wheel-and-tire presentation all matter, so tire choice affects both appearance and driving character. This model uses radial fitments in two sizes, 245/40R18 and 255/35R19, making wheel diameter the first thing to confirm. Available choices range from blackwall performance-oriented tires to redline and raised white letter options in 18-inch fitment. The right selection depends on whether the car is staying stock, pursuing a specific look, or working around aftermarket wheel changes.
Which Tire Size Is Right for The 2023 Audi A5 Quattro
The 2023 Audi A5 Quattro uses two primary tire sizes, and both are radial constructions. The key difference is wheel diameter: one fitment is built around an 18-inch rim and the other around a 19-inch rim. Since the covered Premium, Premium Plus, and Prestige coupe and cabriolet sub-models can use either size, the first step is confirming which wheels are actually on the car before comparing brands, sidewall styles, and tire series.
Fit(s): Premium Cabriolet, Premium Coupe, Premium Plus Cabriolet, Premium Plus Coupe, Prestige Cabriolet, and Prestige Coupe
Construction: Radial|Rim: 18 in
245/40R18 is a metric radial size where 245 is the nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2023 Audi A5 Quattro, this size suits the 18-inch wheel setup and represents a modern low-profile fitment rather than a vintage sizing system. Available choices include blackwall performance-oriented tires from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, along with redline and raised white letter options in the Pro-Trac Street Pro III series. This size is the right path when the car is equipped with 18-inch wheels and the goal is to compare style and use priorities within that setup.

Construction: Radial|Rim: 19 in
255/35R19 is a metric radial size in which 255 is the nominal section width in millimeters, 35 is the aspect ratio, R denotes radial construction, and 19 is the rim diameter in inches. For the 2023 Audi A5 Quattro, this size belongs to the 19-inch wheel fitment and carries a slightly wider, lower-profile presentation than the 18-inch option. Product choices here center on blackwall radial performance lines from BFGoodrich, including the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This is the size to evaluate when the car already wears 19-inch wheels and the priority is matching that wheel package correctly.
Tire fitment across the 2023 Audi A5 Quattro range is straightforward in one sense and worth checking in another. Premium, Premium Plus, and Prestige coupe and cabriolet versions all use the same two radial size families, so the important step is confirming whether the car has the 18-inch or 19-inch wheel setup.

2023 Audi A5 Quattro Premium Cabriolet
The 2023 Audi A5 Quattro Premium Cabriolet uses the same two radial fitment paths found across the covered A5 Quattro range. Tire selection comes down to confirming whether the convertible is on 18-inch or 19-inch wheels, then comparing the available brands, series, and sidewall treatments within that wheel size.
The 2023 Audi A5 Quattro Premium Coupe shares the same radial tire-size choices as the other supported coupe and cabriolet versions. That means the practical decision is not trim-based but wheel-based, so checking the actual rim diameter on the car is the key step before choosing among the available tire lines.
The 2023 Audi A5 Quattro Premium Plus Cabriolet follows the same overall fitment pattern as the rest of the covered model range, with two radial size options tied to wheel diameter. A buyer choosing tires for this sub-model should verify the wheel setup first and then focus on the desired mix of appearance and road use.
The 2023 Audi A5 Quattro Premium Plus Coupe uses the same pair of radial tire fitments as the other listed A5 Quattro sub-models. Because the sizes are shared across trims, the most important check is whether the coupe is wearing 18-inch or 19-inch wheels before narrowing the choice to a specific brand or tire series.
The 2023 Audi A5 Quattro Prestige Cabriolet is covered by the same two radial tire-size options used across the supported A5 Quattro lineup. That keeps trim-level fitment simple, but it still makes wheel confirmation essential, especially if the car has been changed from its original wheel package.
The 2023 Audi A5 Quattro Prestige Coupe shares its tire-size choices with the other covered Premium, Premium Plus, and Prestige models. Selecting the right tire starts with confirming the car's wheel diameter, then deciding whether the priority is a blackwall performance look or one of the available styling-oriented 18-inch 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.

Tire Size & Fitment
What tire size fits a 2023 Audi A5 Quattro?
The 2023 Audi A5 Quattro uses two primary tire sizes: 245/40R18 and 255/35R19. Both are radial fitments, and both appear across the supported Premium, Premium Plus, and Prestige coupe and cabriolet versions. The difference between them is tied to wheel diameter rather than a separate construction type.
Choosing between those sizes starts with the wheels actually on the car. An 18-inch wheel takes the 245/40R18 fitment, while a 19-inch wheel uses 255/35R19. If the car has been changed from its original wheel package, confirm the rim diameter and width before selecting a tire so the new set matches the wheel and available clearance.
What size rim does a 2023 Audi A5 Quattro use?
The 2023 Audi A5 Quattro uses either an 18-inch or 19-inch rim, depending on which tire size is on the car. The 245/40R18 size is built for an 18-inch wheel, and the 255/35R19 size is built for a 19-inch wheel. Both fitment paths are part of the covered A5 Quattro range.
Rim diameter is the first thing to verify because the two tire sizes are not interchangeable across those wheel diameters. After that, compare the wheel width against the tire's acceptable rim-width range when that information is available. This becomes especially important if the A5 Quattro has aftermarket wheels or a staggered-looking setup that differs from standard trim presentation.
Do all 2023 Audi A5 Quattro sub-models use the same tire size?
The covered 2023 Audi A5 Quattro sub-models all share the same two tire size choices rather than having separate trim-exclusive sizes. Premium, Premium Plus, and Prestige versions in both coupe and cabriolet form can use 245/40R18 or 255/35R19, with both sizes built as radial tires.
That makes sub-model identification less critical than wheel confirmation. The practical step is checking whether the car is on 18-inch or 19-inch wheels, then selecting within that size. Looking at the tire sidewall and wheel diameter before ordering helps avoid choosing a correct A5 Quattro size that still does not match the specific wheels on the car.
Choosing the Right Tire
What should I consider when choosing a 245/40R18 or 255/35R19 tire for a 2023 Audi A5 Quattro?
Start with the correct size for the wheels on the car, because the 2023 Audi A5 Quattro uses either 245/40R18 or 255/35R19 radial tires. After size, the next comparison points are tire series, brand, sidewall treatment, and rim-width suitability. Those factors shape how the tire looks on the car and how closely it matches the intended use.
An 18-inch A5 Quattro opens more appearance choices, including blackwall, redline, and raised white letter options, while 19-inch choices here are blackwall performance-oriented tires. It also helps to compare load figures, when stated, and to confirm the wheel width against the tire's approved range. That keeps the selection grounded in both visual goals and correct wheel compatibility.
What sidewall styles are available for 2023 Audi A5 Quattro tires?
Sidewall choices for the 2023 Audi A5 Quattro include blackwall across both primary sizes, plus redline and raised white letter options in the 245/40R18 fitment. That means the 18-inch setup offers the widest appearance range, while the 255/35R19 products shown stay focused on a blackwall presentation.
The practical choice depends on whether the car is meant to keep a modern understated look or add more visual character. A blackwall tire generally preserves the contemporary factory-style feel of the A5, while redline or raised white letter sidewalls create a more customized presentation. Sidewall style should be chosen only after confirming the correct tire size and wheel diameter.
What brands offer tires for the 2023 Audi A5 Quattro?
Available brands for the 2023 Audi A5 Quattro include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, depending on the tire size. The 245/40R18 fitment has the broadest brand spread, while the 255/35R19 options shown are centered on BFGoodrich. All of the listed choices are radial tires.
Brand comparison should be tied to the exact wheel size and the kind of tire presentation you want. Some lines lean toward blackwall performance-oriented styling, while others add visual alternatives such as redline or raised white letter sidewalls. It also helps to compare series names, rim-width compatibility, and stated load details where available instead of choosing by brand name alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Audi A5 Quattro?
Yes, modifications can affect tire fitment on a 2023 Audi A5 Quattro even when the tire size itself is correct. Aftermarket wheels, changes in wheel width or offset, suspension lowering, and body alterations can all change how a 245/40R18 or 255/35R19 tire sits in the wheel opening and how much steering or fender clearance remains.
A modified car should be checked at full steering lock and through normal suspension movement before settling on a new tire. Wheel diameter still has to match the tire size, but width and offset can matter just as much. Looking at the current wheel specs and measuring clearances is especially worthwhile if the A5 Quattro no longer uses its original wheel setup.
What should I inspect before driving a 2023 Audi A5 Quattro on new tires?
Before driving a 2023 Audi A5 Quattro on new tires, inspect the wheel condition, confirm the wheel diameter matches the tire size, and verify that all four tires are properly seated and inflated. It is also wise to look over the suspension and steering components for obvious wear, since new tires can make existing alignment or handling issues more noticeable.
A short initial drive should include listening for rubbing, vibration, or pull, especially if the car has different wheels than expected for its trim. Rechecking pressure after installation and watching for any air loss during the first days of use helps catch problems early. That same inspection routine is useful whether the car runs the 18-inch or 19-inch fitment.
How often should tires on a 2023 Audi A5 Quattro be inspected?
Tires on a 2023 Audi A5 Quattro should be inspected regularly rather than only at replacement time. A quick visual check before longer drives and a more careful inspection at routine service intervals helps catch uneven wear, cuts, sidewall damage, embedded debris, or pressure loss before those problems become larger and more expensive.
Cars that are driven less often still need attention, because age and storage conditions can affect tire condition even when tread depth looks acceptable. Looking at both inner and outer sidewalls, monitoring inflation, and checking for wear patterns can reveal alignment or suspension concerns. Frequent inspection is especially important if the A5 Quattro is driven spiritedly or uses aftermarket wheels.
