The 2015 Audi RS5 sits in the modern high-performance coupe and cabriolet world with a strong emphasis on sharp handling, aggressive stance, and everyday road manners that still feel distinctly special. For tire selection, that means fitment matters just as much as appearance, because wheel diameter and tire profile are central to how the car sits and responds. This RS5 uses radial tires in two primary sizes, 265/35R19 and 275/30R20, both with low-profile metric sizing. Available choices center on blackwall performance tires from BFGoodrich and Nitto, so the key decision is confirming the wheel setup on your exact car before choosing the right series and specification.
Which Tire Size Is Right for The 2015 Audi RS5
The 2015 Audi RS5 uses two primary tire sizes, and the first step is confirming which wheel diameter is on the car. Both the Base and Cabriolet can use either 265/35R19 or 275/30R20, so the real fitment decision starts with identifying whether your RS5 is on 19-inch or 20-inch wheels before comparing available tire choices within that size.
265/35R19 is a modern metric radial size in which 265 is the section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 19 is the rim diameter in inches. On the 2015 Audi RS5, this size suits a low-profile performance setup built around a 19-inch wheel. Available choices include BFGoodrich and Nitto, with blackwall sidewalls and series such as g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This size is the right place to start if your RS5 is equipped with 19-inch wheels and you want to compare brand, series, and rim-width compatibility.
275/30R20 is a modern metric radial size where 275 gives the section width in millimeters, 30 is the aspect ratio, R indicates radial construction, and 20 refers to the rim diameter in inches. For the 2015 Audi RS5, it represents the 20-inch wheel fitment and keeps the car in a very low-profile performance tire range. The available product choice in this size is a blackwall Nitto NT555 G2. This size should be evaluated when the car is already on 20-inch wheels and you want to maintain the correct rim diameter and profile family.
Tire fitment is straightforward across the covered 2015 Audi RS5 sub-models because both use the same two primary sizes. Checking the exact sub-model still helps, but wheel diameter remains the more important detail when selecting between the 19-inch and 20-inch fitments.

2015 Audi RS5 Base
The 2015 Audi RS5 Base uses the same two radial tire sizes seen across this model line, so size selection depends on the wheel package installed on the car. Tire choice then comes down to confirming 19-inch versus 20-inch wheels and comparing the available blackwall performance tire options within that size.
The 2015 Audi RS5 Cabriolet shares the same two radial tire sizes as the Base model, which keeps fitment consistent across the covered sub-models. The key step is verifying whether the car is on 19-inch or 20-inch wheels, then selecting the appropriate performance tire series for that wheel diameter.
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.

Available 2015 Audi RS5 tire choices focus on blackwall radial performance tires from BFGoodrich and Nitto. The 265/35R19 fitment offers the broader comparison across multiple series, while 275/30R20 currently centers on the Nitto NT555 G2.
Common 2015 Audi RS5 tire questions usually come down to confirming 19-inch versus 20-inch wheel fitment, understanding the metric size codes, and comparing available radial performance tire options by brand, series, and intended use.
Tire Size & Fitment
What tire size fits a 2015 Audi RS5?
The 2015 Audi RS5 uses two primary tire sizes: 265/35R19 and 275/30R20. Both are radial metric sizes, and both apply to the RS5 Base and RS5 Cabriolet, so the vehicle does not split fitment by sub-model in this case.
The important distinction is wheel diameter. A car on 19-inch wheels needs the 265/35R19 fitment, while a car on 20-inch wheels needs the 275/30R20 fitment. Before choosing a tire, check the wheel size actually mounted on the vehicle, especially if it has been changed from its previous setup.
What size rim does a 2015 Audi RS5 use?
A 2015 Audi RS5 uses either a 19-inch or 20-inch rim, depending on which tire size is on the car. The 265/35R19 fitment matches a 19-inch rim, while the 275/30R20 fitment matches a 20-inch rim.
That makes rim diameter the first fitment check before comparing tires. A 19-inch tire cannot be mounted on a 20-inch wheel, and a 20-inch tire cannot be mounted on a 19-inch wheel. It is also smart to confirm wheel width and overall clearance if the car has aftermarket wheels or suspension changes.
Do all 2015 Audi RS5 sub-models use the same tire size?
The 2015 Audi RS5 Base and 2015 Audi RS5 Cabriolet both use the same two primary tire sizes: 265/35R19 and 275/30R20. That means the fitment pattern is shared across the covered sub-models rather than being split between coupe and convertible versions.
Even with that shared fitment, the exact tire you need still depends on the wheel diameter installed on your car. The practical next step is not choosing by sub-model alone, but checking whether the vehicle is on 19-inch or 20-inch wheels and then selecting the correct tire size for that setup.
Choosing the Right Tire
What should I consider when choosing a 265/35R19 tire for a 2015 Audi RS5?
Start with the correct size, then compare the available 265/35R19 radial choices by brand, tire series, and wheel compatibility. In this fitment, options include BFGoodrich and Nitto blackwall performance tires, and one 265/35R19 product also specifies a 9 to 10.5 inch rim-width range.
The decision usually comes down to how you use the car and how closely you want the tire’s specification to match your wheel setup. An RS5 driven regularly may call for a different series preference than one used more selectively, and confirming wheel width helps narrow the most appropriate option within the same size.
What brands offer tires for the 2015 Audi RS5?
The available brands for the 2015 Audi RS5 are BFGoodrich and Nitto. In 265/35R19, both brands are represented, while the 275/30R20 fitment currently centers on Nitto through the NT555 G2 series.
Brand is only one part of the decision, so it helps to compare it alongside size, series, and wheel compatibility. A broader product spread exists in the 19-inch fitment, which gives more room to compare, while the 20-inch fitment is narrower and makes confirming the exact wheel diameter especially important.
What tire series are available for the 2015 Audi RS5?
The 2015 Audi RS5 is covered by several radial performance tire series, including BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. These series appear within the RS5’s supported 19-inch and 20-inch fitments rather than across a single universal size.
Series names help distinguish product character within the correct tire size, but they should be compared only after confirming the wheel diameter on the car. Once the correct size is established, looking at series, brand, sidewall style, and any stated rim-width specification gives a clearer picture of the right match for your setup.
Restoration & Appearance
Which tire should I choose for a period-style 2015 Audi RS5?
A period-style approach for a 2015 Audi RS5 usually starts with keeping the correct modern radial size for the wheel diameter already on the car. That means choosing within 265/35R19 or 275/30R20 rather than moving away from the low-profile metric fitment that suits the RS5’s original era and character.
Appearance choices are more limited here than on many older collector vehicles, since the available options are blackwall performance tires rather than vintage-style whitewall or bias-ply designs. For an owner focused on preserving the car’s original visual impression, staying with the correct size and wheel diameter is usually more important than chasing visual variation.
Does correct tire fitment matter for a 2015 Audi RS5 restoration?
Correct tire fitment matters because the 2015 Audi RS5 was built around low-profile radial sizing, and the wrong diameter or profile can change the way the car sits visually and how the wheel-and-tire package fills the arches. Using 265/35R19 or 275/30R20 keeps the restoration grounded in the proper fitment family.
For a restoration-oriented RS5, confirm the actual wheel size on the car before selecting a replacement tire. If originality is especially important, compare the current wheel setup against the vehicle’s own equipment history and retain a tire size that matches the intended 19-inch or 20-inch presentation rather than improvising with unrelated dimensions.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Audi RS5?
Yes. A 2015 Audi RS5 may use either 265/35R19 or 275/30R20, so aftermarket wheels, altered offsets, suspension changes, or lowered ride height can all affect whether the original size still suits the car the same way. The tire size alone does not tell the whole story once modifications enter the picture.
A modified RS5 should be checked for wheel diameter, wheel width, and clearance at the fender and suspension before choosing replacement tires. Steering travel is worth checking as well. Even when the tire size matches one of the known RS5 fitments, the actual wheel-and-chassis setup can still change what works comfortably.
What should I inspect before driving a 2015 Audi RS5 on new tires?
Before driving a 2015 Audi RS5 on new tires, confirm the installed tire size matches the wheel diameter, then inspect inflation pressure, wheel condition, valve stems, and basic clearance around the suspension and body. It also helps to look over the tread and sidewalls after mounting to make sure there is no visible damage or irregularity.
A short initial road test is a smart follow-up. Listen for rubbing, feel for vibration, and recheck pressure after the first drive. On a performance-oriented car like the RS5, a tire that is correctly sized but poorly matched to the wheel or installed on a damaged rim can still create problems that need attention right away.
How often should tires on a 2015 Audi RS5 be inspected?
Tires on a 2015 Audi RS5 should be inspected regularly, not just when tread looks low. A performance car with low-profile radial tires benefits from routine checks for pressure loss, uneven wear, cuts, bulges, and sidewall damage, especially if the car sees spirited driving or long periods of storage between outings.
A practical habit is to inspect the tires before longer drives and any time the car feels different on the road. Collector-minded owners should also watch for age-related deterioration, since a lightly driven tire can still become unsuitable with time. Keeping wheels clean and pressures consistent helps catch developing issues earlier.
