2024 Audi A5 Quattro Tires

The 2024 Audi A5 Quattro uses two primary tire sizes: 245/40R18 and 255/35R19. Both are modern radial fitments, and the correct one depends on the wheel package and exact sub-model configuration on the car.

Most Premium, Premium Plus, and Prestige coupe and cabriolet versions can use either size, while the covered Black Optic Package coupes use 255/35R19. The practical first step is checking the wheel diameter actually installed on the vehicle, since an 18-inch tire and a 19-inch tire are not interchangeable just because they fit the same model line.

A 2024 Audi A5 Quattro uses either an 18-inch or 19-inch rim, depending on which tire size belongs on the car. The 245/40R18 fitment goes with an 18-inch wheel, and the 255/35R19 fitment goes with a 19-inch wheel.

Wheel diameter is the key fitment check before comparing tires. After confirming 18 versus 19 inches, it also helps to review wheel width against the tire you are considering, especially if the car has replacement wheels or a package-specific setup. That keeps the selection centered on the correct size family before looking at sidewall style or product series.

No. The 2024 Audi A5 Quattro family uses both 245/40R18 and 255/35R19, and many covered sub-models can appear with either size. Premium, Premium Plus, and Prestige coupe and cabriolet versions share that two-size pattern, while the covered Black Optic Package coupes use 255/35R19.

That means sub-model name alone does not always settle the fitment question. It is important to identify both the exact trim and the wheel diameter on the car before ordering tires. A quick check of the existing wheel and tire markings is usually the simplest way to avoid choosing an 18-inch tire for a 19-inch setup or the reverse.

Start with the correct tire size for the wheel package on the car, since the 2024 Audi A5 Quattro uses either 245/40R18 or 255/35R19. From there, compare construction, tire series, sidewall treatment, rim-width suitability, and the kind of driving the car sees most often.

A buyer choosing 245/40R18 has a broader mix of product styles, including blackwall, redline, and RWL choices, while 255/35R19 centers on blackwall performance radials. Looking at wheel width, tire weight, and load figures where available can help narrow the decision further. The right choice depends on matching the tire to the car's actual wheels and intended use rather than choosing by brand name alone.

Sidewall style depends on tire size. In 245/40R18, available styles include blackwall, redline, and RWL, while the current 255/35R19 options are blackwall. That gives the 18-inch fitment a wider appearance range than the 19-inch fitment.

For many buyers, sidewall style is an appearance decision layered on top of correct fitment. Blackwall keeps a more contemporary presentation, while redline or raised white letter options can create a more custom visual effect. The key is to confirm the size first, then choose the sidewall treatment that suits the car's look without losing sight of wheel compatibility and intended road use.

Available brands for the 2024 Audi A5 Quattro include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac. Brand availability varies by size, with the 245/40R18 fitment offering the broadest mix and the 255/35R19 fitment centered on BFGoodrich choices.

Brand should be one part of the decision, not the only one. It helps to compare the series offered in the correct size, the sidewall style you want, and whether the tire's rim-width specification suits the wheel on the car. That approach is more useful than treating every tire in a given brand as the same, especially when the two A5 Quattro fitments have different product depth.

A period-style approach on a 2024 Audi A5 Quattro still begins with the correct modern radial size, either 245/40R18 or 255/35R19, based on the wheel package. Within that fitment, the 18-inch size offers the widest visual flexibility, including blackwall, redline, and RWL choices.

Because this is a current-era Audi rather than a restoration-era classic, appearance usually comes down to matching the tire's visual character to the car's wheels and trim rather than chasing historical originality. Keeping the correct size and wheel diameter intact matters more than forcing a style choice that does not suit the actual setup on the vehicle.

For a 2024 Audi A5 Quattro, blackwall is the most restrained and contemporary-looking sidewall style available across both fitments. The 245/40R18 size also opens the door to redline and RWL choices for owners who want a more customized visual statement.

The best match depends on the wheel design and overall look of the car. A subtle build often works best with blackwalls, while redline or raised white letters can stand out more on an 18-inch setup. Since sidewall style does not change the need for correct fitment, the smart order is size first, appearance second.

Yes. Modifications can affect tire fitment on a 2024 Audi A5 Quattro even when the tire size itself is correct. Aftermarket wheels, changes in wheel width, offset differences, lowered suspension, and body or brake-package changes can all alter clearance around the tire.

That matters most when choosing between the 18-inch and 19-inch fitments or replacing tires on a car that no longer has its original wheel setup. A good check includes wheel diameter, wheel width, steering clearance, and fender clearance at full lock and full suspension movement. That keeps a correct-size tire from becoming a poor real-world fit on a modified car.

Before driving a 2024 Audi A5 Quattro on new tires, confirm the tire size matches the wheel diameter, inspect the wheels for damage, and make sure inflation pressure is set appropriately for the tire and vehicle setup. It also helps to verify that valve stems and balancing are in proper condition.

A short road check after installation is worthwhile. Listen for rubbing, feel for vibration, and recheck pressure after the tires have settled in service. Looking over the suspension and alignment condition is also smart, since worn components can affect how a new tire wears and how the car responds on the road.

Tires on a 2024 Audi A5 Quattro should be inspected regularly, not just when they look worn. Pressure, tread condition, cuts, punctures, uneven wear, and sidewall damage all deserve attention, especially on a car that may switch between seasonal or package-specific wheel and tire setups.

Monthly visual checks are a sensible baseline, with a closer inspection before longer trips or after any impact with potholes or road debris. It is also worth checking the inner sidewall and shoulder area, since damage there is easy to miss. Regular inspection helps catch issues early and keeps the correct 18-inch or 19-inch fitment performing as intended.
