The 2014 Audi A5 Quattro blends Audi’s sleek coupe and cabriolet design language with all-wheel-drive confidence, making it a popular modern German grand touring platform. For owners, tire selection is less about vintage-style construction and more about confirming the correct wheel setup, since this model uses either 245/40R18 or 255/35R19 radial tires. Both sizes keep the focus on responsive street manners, but the available choices still vary by tire series, load specification, and sidewall presentation, including blackwall, redline, and raised white letter options in 18-inch fitment. The right choice starts with matching the car’s actual rim diameter and then selecting the tire character that suits daily use, appearance, or specialized performance driving.
Which Tire Size Is Right for The 2014 Audi A5 Quattro
The 2014 Audi A5 Quattro uses two primary tire sizes, and the first step is confirming whether the car is on 18-inch or 19-inch wheels. Both sizes are radial fitments and both appear on the Base and Cabriolet, so the real decision is matching the tire to the wheel diameter already on the car and then choosing the right series, sidewall style, and intended use.
245/40R18 is a modern metric radial size in which 245 identifies the nominal section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 18 is the wheel diameter in inches. On the 2014 Audi A5 Quattro, this size supports an 18-inch wheel setup and brings the broadest product variety of the two fitments. Available choices include blackwall performance-oriented tires from BFGoodrich, Nitto, and M&H Racemaster, along with redline and raised white letter Pro-Trac options. It is the size to evaluate if the car currently wears 18-inch rims and you want the widest spread of appearance and use-case choices.
255/35R19 is also a modern metric radial size, with a 255-millimeter nominal section width, a 35-series aspect ratio, radial construction, and a 19-inch rim diameter. For the 2014 Audi A5 Quattro, this size belongs to a 19-inch wheel package and keeps the selection centered on blackwall radial performance tires. BFGoodrich offers this fitment across multiple g-Force series, including all-season and sport-focused options. This size is the one to compare when the car is already equipped with 19-inch wheels and the priority is staying with the proper rim diameter while choosing among available performance-style radials.
Tire fitment is straightforward across the covered 2014 Audi A5 Quattro sub-models because both the Base and Cabriolet use the same two primary radial sizes. The important check is not the trim name alone, but whether the car is currently on 18-inch or 19-inch wheels.

2014 Audi A5 Quattro Base
The 2014 Audi A5 Quattro Base uses the same two radial fitments found across this model range, so selection comes down to the wheel diameter installed on the car. Once the 18-inch or 19-inch setup is confirmed, attention can shift to tire series, sidewall style, and intended road use.
The 2014 Audi A5 Quattro Cabriolet follows the same tire-size pattern as the Base model, with both 18-inch and 19-inch radial fitments used. That keeps the process simple: verify the wheel diameter on the car first, then compare the available tire options within the matching size.
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 2014 Audi A5 Quattro?
The 2014 Audi A5 Quattro uses two primary tire sizes: 245/40R18 and 255/35R19. Both are radial fitments, and both appear on the Base and Cabriolet versions, so neither size is tied to only one sub-model within this group.
The key is confirming which wheel diameter is actually on the car before choosing a tire. An A5 Quattro on 18-inch wheels needs the 245/40R18 fitment, while a car on 19-inch wheels needs 255/35R19. If the vehicle has been modified with aftermarket wheels, verify the current wheel size and width before ordering replacement tires.
What size rim does a 2014 Audi A5 Quattro use?
The 2014 Audi A5 Quattro uses either an 18-inch or 19-inch rim, depending on which of its two primary tire sizes 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.
Rim diameter is the first fitment detail to verify because tire size cannot be separated from wheel size. A tire made for an 18-inch rim cannot be mounted on a 19-inch wheel, and vice versa. It also helps to confirm wheel width, especially if the car is running non-stock wheels or a performance-oriented setup.
Do all 2014 Audi A5 Quattro sub-models use the same tire size?
The Base and Cabriolet versions of the 2014 Audi A5 Quattro share the same two tire sizes: 245/40R18 and 255/35R19. That means fitment does not split by these sub-model names alone in the covered range.
Even with shared sub-model fitment, the tire choice still depends on the wheel package installed on the individual car. A quick check of the current tire sidewall or wheel diameter will settle which size applies. That matters more than the body style once the search is narrowed to the Base or Cabriolet.
Choosing the Right Tire
What should I consider when choosing a tire for a 2014 Audi A5 Quattro?
Start with the correct size for the wheel on the car: 245/40R18 for 18-inch rims or 255/35R19 for 19-inch rims. From there, compare construction, tire series, sidewall style, rim-width suitability, and whether the car is used mainly for everyday street driving or a more specialized purpose.
The 18-inch fitment offers the widest mix of choices, including street-performance radials, a drag-focused radial, and appearance-oriented redline or raised white letter options. The 19-inch fitment stays more focused on blackwall performance tires. Matching the tire to the car’s actual wheel setup and intended use will narrow the field quickly.
What sidewall styles are available for 2014 Audi A5 Quattro tires?
Sidewall style depends on the tire size and product line. In 245/40R18, available sidewall treatments include blackwall, redline, and RWL, which stands for raised white letter. The 255/35R19 fitment stays with blackwall options in the available product range.
That makes the 18-inch size the better place to look if visual style matters as much as basic fitment. A blackwall keeps a more understated modern appearance, while redline or raised white letters create a more noticeable custom look. Sidewall style should still be chosen only after confirming the tire size and wheel diameter on the car.
What brands offer tires for the 2014 Audi A5 Quattro?
Available brands for the 2014 Audi A5 Quattro include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac. Brand choice varies by size, with the 245/40R18 fitment carrying the broadest spread and the 255/35R19 fitment centered on BFGoodrich offerings.
Brand alone should not be the only deciding factor. It helps to compare the actual tire series, the intended use, the sidewall treatment, and the wheel-width range that works with each size. That approach is especially important when one size, such as 245/40R18, includes both conventional street tires and a drag-oriented radial option.
Restoration & Appearance
Which tire should I choose for a period-style 2014 Audi A5 Quattro?
A period-style choice for a 2014 Audi A5 Quattro usually starts with keeping the correct wheel diameter and then choosing a sidewall treatment that suits the look you want. In the available product range, 245/40R18 gives the most appearance flexibility, including blackwall, redline, and raised white letter options.
Because this is a modern Audi rather than a vintage restoration car, period-style usually means staying visually consistent with the era instead of chasing strict factory originality. A discreet blackwall will feel closest to the car’s original design language, while redline or RWL creates a more custom presentation. The visual decision still has to follow the actual wheel size on the car.
How does tire construction affect the appearance of a restored 2014 Audi A5 Quattro?
On the 2014 Audi A5 Quattro, tire construction is less about bias-ply versus radial appearance and more about choosing among modern radial products with different visual treatments. Both primary sizes are radial, so the appearance change comes mainly from sidewall style, tire series, and the wheel diameter already fitted to the car.
That means an owner restoring or refreshing the car’s appearance should pay close attention to whether the goal is a clean OEM-inspired look or something more personalized. Blackwall tires keep the most contemporary European feel, while redline or raised white letter options shift the car toward a more custom statement. Wheel size remains the foundation of the final look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Audi A5 Quattro?
Yes, modifications can affect tire fitment on a 2014 Audi A5 Quattro even when the tire size itself is correct. Aftermarket wheels, suspension changes, altered ride height, or spacer use can change how much room the tire has at the fender, suspension, and steering components.
That is why the car’s current setup matters as much as the original fitment range. An owner should confirm wheel diameter, wheel width, and general clearance before replacing tires on a modified car. Looking at the existing tire size stamped on the sidewall is helpful, but it should not replace a physical check of the wheel and suspension package.
What should I inspect before driving a 2014 Audi A5 Quattro on new tires?
Before driving a 2014 Audi A5 Quattro on new tires, inspect the wheels for correct diameter and visible damage, confirm proper tire pressure, and make sure the tires clear the fenders and suspension at full steering lock. It is also smart to verify that all four tires match the intended size and construction.
A short, careful road test can reveal vibration, rubbing, or balance issues before the car is driven harder or farther. On a vehicle that has sat for a while, it also helps to inspect the suspension and alignment-related wear patterns. New tires perform best when the surrounding hardware is in equally sound condition.
How should tires on a 2014 Audi A5 Quattro be maintained?
Tires on a 2014 Audi A5 Quattro should be maintained with regular pressure checks, routine visual inspection, and attention to uneven tread wear. Owners should look for cuts, bulges, sidewall cracking, punctures, and signs of slow air loss, especially if the car is driven infrequently or stored for long periods.
Good maintenance also means keeping the tires protected from long exposure to sunlight, excess heat, and ozone sources during storage. It helps to inspect them before longer trips rather than assuming low-mileage tires are automatically road-ready. A collector or seasonal-use car can age its tires out long before it wears them out.
