2016 Audi A5 Quattro Tires

The 2016 Audi A5 Quattro uses two primary tire sizes: 245/40R18 and 255/35R19. Both are radial fitments, but they do not apply the same way across every version of the car. Premium Coupe and Premium Cabriolet models use 245/40R18, while Premium Plus Coupe and Premium Plus Cabriolet can use either 245/40R18 or 255/35R19.

That means the right choice starts with identifying the exact sub-model and then confirming the wheels on the car. A tire size tied to a 19-inch rim should not be treated as an automatic alternative for an 18-inch wheel setup, even within the same year and model.

The 2016 Audi A5 Quattro uses either an 18-inch or 19-inch rim, depending on the tire size fitted to the car. The 245/40R18 size uses an 18-inch rim, and the 255/35R19 size uses a 19-inch rim. Both are modern radial fitments rather than vintage bias-ply sizing systems.

Rim diameter is the first thing to confirm before shopping, because it determines which tire size family even belongs on the car. Once wheel diameter is verified, it also helps to compare wheel width and make sure any aftermarket wheel or trim-specific setup still matches the intended tire.

No, not every 2016 Audi A5 Quattro sub-model uses the same tire size. The Premium Coupe and Premium Cabriolet use 245/40R18, while the Premium Plus Coupe and Premium Plus Cabriolet can use either 245/40R18 or 255/35R19. The difference is tied to the specific configuration and wheel package.

That variation matters because the two sizes use different rim diameters and create different buying choices. Anyone replacing tires on a Premium Plus car should check the actual wheels installed rather than relying only on the model name, especially if the car has had previous wheel changes.

Start by confirming that 245/40R18 is the correct fitment for the car’s exact sub-model and wheel setup. In this size, the 2016 Audi A5 Quattro has several radial choices, including blackwall performance tires from BFGoodrich, Nitto, and M&H Racemaster, plus Pro-Trac Street Pro III options in redline and RWL sidewall treatments.

After size confirmation, compare the tire’s intended use and visual presentation. Some choices lean toward performance street driving, while others add a more distinctive sidewall look. Rim-width compatibility, load figures where stated, and the car’s actual use matter more than simply choosing by brand name alone.

Sidewall style depends on tire size. In 245/40R18, available sidewall treatments include blackwall, redline, and RWL. In 255/35R19, the available choices are blackwall performance radials. That gives the 18-inch fitment more visual variety, while the 19-inch fitment stays focused on a contemporary blackwall presentation.

Sidewall style is mainly an appearance decision once the correct size is established. A redline or raised white letter treatment can change the look of the car considerably, but the tire still needs to match the wheel diameter, intended use, and overall fitment priorities for that specific A5 Quattro.

Tires for the 2016 Audi A5 Quattro are available from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, depending on the size. The 245/40R18 fitment has the broadest mix of brands and sidewall choices, while the 255/35R19 fitment is represented here by BFGoodrich performance radial options.

Brand is only one part of the decision. It helps to compare the tire series, sidewall style, rim-width specification, and intended use inside the correct size first. A buyer choosing for a Premium Plus car should settle the 18-inch versus 19-inch wheel question before comparing one brand’s 18-inch tire to another brand’s 19-inch tire.

A period-style choice for a 2016 Audi A5 Quattro starts with keeping the correct modern radial size for the car’s wheel setup, either 245/40R18 or 255/35R19. From there, the look differs by size. The 245/40R18 fitment offers blackwall, redline, and RWL choices, while the 255/35R19 options shown here stay with a blackwall performance appearance.

For a factory-inspired presentation, many owners will want the sidewall and profile to suit the car’s original character as a modern Audi rather than forcing a vintage look onto it. Matching the installed wheel diameter is the first step, and visual preference should follow only after size and sub-model fitment are settled.

On the 2016 Audi A5 Quattro, the primary fitments are modern radial tires, so the appearance question is less about bias-ply versus radial and more about profile, wheel diameter, and sidewall treatment. A 245/40R18 with a blackwall, redline, or RWL sidewall creates a different visual impression than a 255/35R19 blackwall performance radial.

The car’s look is shaped by how the tire fills the wheel opening and how the sidewall complements the body style. Buyers trying to preserve a clean, era-appropriate presentation should keep the correct size family in place first, then choose the sidewall style that best fits the desired overall appearance.

Yes, modifications can affect tire fitment on a 2016 Audi A5 Quattro. Wheel changes, suspension lowering, altered offsets, and previous owner upgrades can all change how a 245/40R18 or 255/35R19 tire sits in the car. Even when the tire size is correct in principle, the actual setup may create different clearance conditions.

That is why it helps to inspect the car rather than relying only on the model year and trim name. Wheel diameter, wheel width, steering clearance, and fender space should all make sense together, especially on a Premium Plus car that may already be equipped with either 18-inch or 19-inch wheels.

Before driving a 2016 Audi A5 Quattro on new tires, check that the installed size matches the wheel diameter and that the wheels are in sound condition. It also makes sense to look over valve stems, verify inflation, and confirm that there is no rubbing at full steering lock or through normal suspension movement.

A general road-use inspection should also include tread condition on any remaining tires, visible sidewall damage, uneven wear, and signs of alignment or suspension issues. On a modern Quattro car, mismatched wheel or tire setups can create unnecessary problems, so consistency across the complete set is worth confirming before regular driving.

Tires on a 2016 Audi A5 Quattro should be inspected regularly, especially before longer trips, after seasonal storage, or anytime ride quality or steering feel changes. A visual check for cuts, bulges, cracking, uneven tread wear, and low pressure can catch problems early whether the car runs 245/40R18 or 255/35R19 tires.

Cars that are driven less often still need periodic inspection because age and storage conditions matter as much as mileage. Checking pressure consistently and watching for air loss or shoulder wear helps protect both the tires and the driving character expected from a modern Audi chassis.
