The 2017 Audi A5 Quattro blends Audi’s clean coupe-and-cabriolet styling with the all-weather confidence that made the Quattro name so important in the brand’s modern identity. It sits in that space where luxury, everyday drivability, and sporting character all matter, which makes tire selection more than a simple replacement exercise. This model uses radial tires in two fitments, 245/40R18 and 255/35R19, so the first step is confirming which wheel diameter is on the car. From there, the real choice comes down to sidewall style, tire series, and whether the goal is contemporary road manners or a more distinctive enthusiast look.
Which Tire Size Is Right for The 2017 Audi A5 Quattro
The 2017 Audi A5 Quattro uses two primary tire sizes, and both are radial fitments tied to different wheel diameters. Sport Cabriolet and Sport Coupe models can use either 245/40R18 or 255/35R19, so the most important first step is confirming whether the car has 18-inch or 19-inch wheels before comparing tire options.
245/40R18 is a metric radial size in which 245 identifies the section width in millimeters, 40 is the aspect ratio, R denotes radial construction, and 18 is the wheel diameter in inches. On the 2017 Audi A5 Quattro, this size suits the 18-inch wheel fitment and keeps the focus on modern road use rather than vintage-style construction choices. Available options include Blackwall, Redline, and RWL sidewalls from brands such as BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster across several performance-oriented series. It is the right size to evaluate when the car carries 18-inch wheels and you want to compare both appearance and product character within that diameter.
255/35R19 is a metric radial size with a 255-millimeter nominal section width, a 35-series profile, radial construction, and a 19-inch rim diameter. For the 2017 Audi A5 Quattro, this size belongs to the 19-inch wheel setup, so it should be chosen only after wheel diameter has been confirmed. The available selections center on BFGoodrich performance radial lines in Blackwall form, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. This fitment is the one to compare when the car wears 19-inch wheels and the goal is staying within the proper lower-profile tire format for that setup.
Fitment is straightforward across the covered 2017 Audi A5 Quattro sub-models because both the Sport Cabriolet and Sport Coupe use the same two radial tire sizes. What matters most is confirming which wheel diameter is actually on the vehicle before narrowing the tire choice.

2017 Audi A5 Quattro Sport Cabriolet
The 2017 Audi A5 Quattro Sport Cabriolet uses the same two radial fitments found across this model range, with one size tied to 18-inch wheels and the other to 19-inch wheels. Tire selection comes down to confirming the wheel package on the car and then choosing among the available performance-oriented series and sidewall treatments in that size.
The 2017 Audi A5 Quattro Sport Coupe shares the same radial tire-size choices as the Sport Cabriolet, so the key fitment step is verifying whether it has 18-inch or 19-inch wheels. Once that is settled, the decision shifts to comparing available Blackwall or enthusiast-style sidewall options, brand preferences, and tire series within the proper 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.

Owners of a 2017 Audi A5 Quattro usually need to sort out tire size by wheel diameter first, then compare radial tire series, sidewall treatments, and everyday fitment checks. These FAQs focus on those exact decisions for this model.
Tire Size & Fitment
What tire size fits a 2017 Audi A5 Quattro?
The 2017 Audi A5 Quattro uses two primary tire sizes: 245/40R18 and 255/35R19. Both are radial fitments, and both appear on the Sport Cabriolet and Sport Coupe, so the size choice is tied to the wheel package on the car rather than to a unique sub-model-only tire format.
The most useful next step is checking the wheel diameter already on the vehicle. An 18-inch wheel calls for the 245/40R18 fitment, while a 19-inch wheel calls for 255/35R19. If the car has aftermarket wheels, confirm the actual wheel dimensions and make sure the selected tire still matches the wheel and clearance requirements.
What size rim does a 2017 Audi A5 Quattro use?
A 2017 Audi A5 Quattro uses either an 18-inch or 19-inch rim, depending on which tire size is on the car. The 245/40R18 fitment belongs to an 18-inch rim, and the 255/35R19 fitment belongs to a 19-inch rim.
Rim diameter should be confirmed before comparing brands or tread styles because the two tire sizes are not for the same wheel. Looking only at the tire’s width or profile is not enough. Check the wheel itself, the tire sidewall, and the actual setup on the vehicle, especially if previous owners changed wheels or tire packages.
Do all 2017 Audi A5 Quattro sub-models use the same tire size?
The covered 2017 Audi A5 Quattro sub-models share the same two tire sizes rather than each having a separate fitment. Both the Sport Cabriolet and Sport Coupe use 245/40R18 and 255/35R19, with the difference coming from wheel diameter rather than from a different tire construction or a unique sub-model specification.
That makes sub-model identification less important than wheel confirmation. A Sport Cabriolet can wear either size, and a Sport Coupe can as well, so the practical question is which wheels are actually on the car. Once that is confirmed, the buyer can focus on sidewall style, brand, tire series, and intended road use within the correct size.
Choosing the Right Tire
What should I consider when choosing a 2017 Audi A5 Quattro tire?
Start with the correct primary size for the wheel on the car: 245/40R18 for 18-inch rims or 255/35R19 for 19-inch rims. From there, compare radial construction details that matter to your use, such as tire series, sidewall style, rim-width compatibility, weight, and load capacity where those specifications are given.
A daily-driven A5 Quattro may call for a different emphasis than a car used for occasional enthusiast driving or a more appearance-driven setup. The 245/40R18 group offers the broadest visual variety, including Blackwall, Redline, and RWL treatments, while the 255/35R19 choices stay focused on Blackwall performance radials.
What sidewall styles are available for 2017 Audi A5 Quattro tires?
Sidewall choices for the 2017 Audi A5 Quattro include Blackwall, Redline, and RWL, though the full range is not present in both sizes. The broadest sidewall variety appears in 245/40R18, where Blackwall, Redline, and raised white letter options are available, while 255/35R19 offerings shown here are Blackwall only.
That makes sidewall appearance part of the size decision only after wheel diameter has already been settled. If the car uses 18-inch wheels, there is more room to tailor the visual character of the tire. If it uses 19-inch wheels, the selection is more focused on modern performance-oriented Blackwall choices.
What brands offer tires for the 2017 Audi A5 Quattro?
Tires for the 2017 Audi A5 Quattro are available from BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster, depending on the size. The 245/40R18 fitment has the widest brand spread, while the 255/35R19 fitment shown here centers on BFGoodrich performance radial offerings.
Brand comparison is most useful after size and wheel diameter are confirmed. Then the buyer can look at how each product differs in series, sidewall presentation, rim-width specification, and intended character. Instead of choosing by brand name alone, it makes more sense to match the tire’s size, visual style, and usage focus to the car.
Restoration & Appearance
Which tire should I choose for a period-style 2017 Audi A5 Quattro?
A period-style choice for a 2017 Audi A5 Quattro starts with keeping the correct modern radial size for the wheel diameter already on the car. From there, 245/40R18 offers the strongest appearance variation thanks to Blackwall, Redline, and RWL options, while 255/35R19 stays closer to a contemporary Blackwall performance presentation.
That decision depends on whether the goal is a subtle factory-inspired look or a more individualized enthusiast style. Redline and raised white letter sidewalls create a distinct visual statement, but they should be treated as appearance choices rather than assumed original-equipment details. The best result usually comes from matching the sidewall look to the car’s wheels and overall presentation.
How does tire construction affect the appearance of a restored 2017 Audi A5 Quattro?
On a 2017 Audi A5 Quattro, construction is less of a vintage-style question because the primary fitments are already modern radial tires. The visual difference comes more from sidewall treatment and tire series than from choosing between bias-ply and radial, since both primary sizes here remain within contemporary radial formats.
That means appearance decisions should focus on wheel diameter, sidewall style, and the overall stance of the car. A Blackwall tire keeps a clean modern look, while Redline or RWL in 245/40R18 can shift the presentation in a more custom direction. Any appearance-driven change still needs to stay within the correct size for the wheel.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Audi A5 Quattro?
Yes. A 2017 Audi A5 Quattro can be affected by wheel changes, altered offsets, suspension modifications, or ride-height changes even when the tire size itself looks close to stock. Because this model uses both 18-inch and 19-inch fitments, aftermarket changes can easily blur which tire size is actually appropriate for the car.
The safest approach is to confirm the actual wheel diameter and width first, then check for clearance at the fenders, suspension, and steering range before selecting a tire. Extra caution is worthwhile if the car has been lowered or fitted with non-original wheels, since fitment can change without being obvious at a glance.
What should I inspect before driving a 2017 Audi A5 Quattro on new tires?
Before driving a 2017 Audi A5 Quattro on new tires, inspect the wheel size, confirm the tire size matches that wheel, and make sure inflation is set correctly for the tire and vehicle setup. It is also wise to look over the wheels themselves for damage, bent lips, or anything that could affect sealing and balance.
A short visual check around the suspension and fender openings can help catch rubbing risks before the car is fully loaded or driven at speed. After installation, pay attention to vibration, steering pull, or unexpected contact. Those signs do not always mean the tire is wrong, but they do mean the fitment should be checked promptly.
How often should tires on a 2017 Audi A5 Quattro be inspected?
Tires on a 2017 Audi A5 Quattro should be inspected regularly, not just when tread looks low. Collector-kept or low-mileage examples especially deserve routine checks for air loss, irregular wear, cuts, bulges, and age-related sidewall cracking, since appearance alone does not always reflect the true condition of a tire.
A practical routine is to check pressure and visible condition before normal driving and to give the tires a closer inspection before longer trips or after seasonal storage. Uneven wear can also point to alignment or suspension issues. Keeping the tires clean, properly inflated, and protected from long exposure to heat and sunlight helps preserve them.
