Audi A7 Quattro Tires

Audi A7 Quattro uses three tire sizes across the 2012 to 2018 model range: 255/45R18 for 2012 to 2013, 255/40R19 for 2012 to 2018, and 265/35R20 for 2012 to 2018. Each size is tied to its own wheel diameter, so 255/45R18 fits 18-inch rims, 255/40R19 fits 19-inch rims, and 265/35R20 fits 20-inch rims.

The practical takeaway is that year alone is not enough on early cars, because 2012 and 2013 can appear with three different fitments. Start by reading the existing sidewall size on the car and confirming the wheel diameter, then compare that to the year listing before settling on a replacement tire.

On an Audi A7 Quattro, 255/40R19 is a modern metric radial size. The 255 is the nominal section width in millimeters, 40 is the aspect ratio expressed as sidewall height relative to width, R means radial construction, and 19 is the required rim diameter in inches.

That decoding matters because each part of the size affects fit, stance, and wheel compatibility. If the car currently wears 19-inch wheels, 255/40R19 keeps you within the listed fitment range; if the wheel is 18 or 20 inches, moving to a different size code is necessary rather than treating the numbers as interchangeable.

A 2012 Audi A7 Quattro can legitimately appear with 255/45R18, 255/40R19, or 265/35R20. Those three sizes correspond to three different wheel diameters, so the split is driven by wheel and configuration differences within the same model year rather than by a single universal tire size.

That means a 2012 car should be identified by its actual wheels before any tire choice is made. Checking only the model year can send you toward the wrong diameter, while verifying the wheel and existing sidewall marking will quickly separate the 18-inch, 19-inch, and 20-inch applications.

Audi A7 Quattro uses three rim diameters in this model group: 18 inches, 19 inches, and 20 inches. The 18-inch fitment appears in 2012 and 2013 with 255/45R18, while 19-inch 255/40R19 and 20-inch 265/35R20 fitments run from 2012 through 2018.

Rim diameter is the first thing to verify because the tire size must match the wheel exactly. If you are unsure, read the full size from the mounted tire or measure the wheel by standard wheel-diameter practice instead of guessing from the vehicle’s appearance.

A 2013 Audi A7 Quattro may use 255/45R18, 255/40R19, or 265/35R20, so the correct answer depends on the car’s actual wheel package. The most direct confirmation comes from the full size molded into the existing tire sidewall, paired with the wheel diameter that size requires.

Once you know whether the car has 18-, 19-, or 20-inch wheels, the fitment path becomes much clearer. It is also smart to compare the current setup with the wheel itself and any service or ownership records, especially if the car may have changed wheels at some point in its life.

Audi A7 Quattro tires in these listed sizes are available in Blackwall, RWL, and Redline sidewall styles. Blackwall appears across all three sizes, while RWL and Redline options are also offered in 18-inch, 19-inch, and 20-inch fitments through the Pro-Trac Street Pro III line.

That gives buyers a choice between a more contemporary understated look and a more custom visual statement. For a cleaner factory-like appearance, Blackwall is the more natural match for an Audi A7 Quattro, while RWL and Redline lean toward a personalized style direction rather than an OEM-style presentation.

Three brands appear in the available Audi A7 Quattro tire selection: BFGoodrich, Nitto, and Pro-Trac. Across the listed sizes, those brands cover several radial series including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Nitto NT555 G2, and Street Pro III.

Brand choice matters after size and wheel diameter are already confirmed. Once the correct fitment is settled, buyers can compare sidewall style, series character, and wheel-width suitability within that size rather than trying to choose a brand first and force the fitment afterward.

Audi A7 Quattro tires are offered here in several radial series, including BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III. The main differences shown are the series family, sidewall presentation, and in some cases wheel-width ranges and load figures within the same general size category.

That means the right series choice comes after you have locked in the correct size and rim diameter. A buyer comparing options within one size should look at the intended visual style, any stated rim-width compatibility, and whether the tire’s overall character suits the way the Audi A7 Quattro will actually be driven.

An Audi A7 Quattro stored on its tires should be kept in a cool, dry, dark space away from direct sunlight, ozone sources, and major temperature swings. Clean tires and proper inflation help prevent flat-spotting, and moving the car slightly from time to time can reduce long stationary loading on one contact patch.

Collectors who keep an Audi A7 Quattro parked for long periods should also avoid resting the car on underinflated tires. If the car will be laid up for an extended season, periodic pressure checks and a brief roll to a new position are simple steps that help preserve both ride quality and appearance.

Tires on an Audi A7 Quattro should be visually inspected before regular road use and more carefully at routine service intervals. Look for cuts, bulges, uneven shoulder wear, sidewall cracking, punctures, and any signs that inflation has drifted away from the intended operating range.

Inspection matters even more on a low-mileage collector car because age and storage conditions can affect tires long before the tread is worn out. A quick walk-around before driving and a more thorough check every few months can catch problems early, especially on lower-profile 19-inch and 20-inch fitments.

Audi A7 Quattro tires should be replaced when they show age cracking, impact damage, exposed cords, repeated air loss, or irregular wear that points to internal or structural trouble, even if tread depth still looks serviceable. Low annual mileage does not stop rubber from aging, and time can matter as much as miles on a modern performance-oriented radial.

That is especially important on a heavier, high-speed-capable car like the Audi A7 Quattro, where tire integrity affects braking, stability, and ride quality. If the car has sat for long periods or has tires of uncertain age, a professional inspection is a smart step before returning it to regular road use.

Audi A7 Quattro appears here with three listed fitment sizes across its production span: 255/45R18, 255/40R19, and 265/35R20. The available products for those sizes are modern radial offerings from BFGoodrich, Nitto, and Pro-Trac, with several different series and sidewall presentations.

Because more than one size can apply in the early years, originality should be checked against the specific car rather than assumed from the model name alone. For an authenticity-minded owner, the best path is to confirm the original wheel package first and then choose a tire that matches the correct size and overall visual character.

Correct tire fitment does affect how an Audi A7 Quattro presents, especially when wheel diameter and sidewall profile shape the car’s stance so strongly. A car wearing the proper 18-, 19-, or 20-inch fitment for its configuration will generally look more coherent and better sorted than one wearing an improvised substitute.

For owners concerned with presentation quality, the key is matching the tire size to the actual wheel package and avoiding casual substitutions that alter profile or proportion. Even on a modern collector candidate, details like sidewall style and overall visual balance can influence how seriously the car is taken.

Audi A7 Quattro tires in these fitments are available in Blackwall, RWL, and Redline versions. Among those, Blackwall is the most natural choice for a restoration-minded or factory-style presentation, while RWL and Redline create a more customized visual effect.

The right answer depends on whether the goal is an OEM-like appearance or a personalized look. If originality and restrained styling matter most, Blackwall will usually align better with the character of an Audi A7 Quattro than a more expressive sidewall treatment.

The listed Audi A7 Quattro tires are modern radial road tires in current metric sizes, so they are intended for public-road use when they are the correct size for the wheel and are in sound condition. Safety still depends on proper wheel diameter matching, suitable inflation, and the absence of age, impact, or wear-related damage.

A practical road-use check starts with confirming that the car’s tires match its 18-, 19-, or 20-inch wheels exactly. After that, inspect the sidewalls and tread, verify pressure, and make sure all four tires are appropriate for the way the Audi A7 Quattro will be driven.

Before driving an Audi A7 Quattro, check tire pressure, visible tire condition, tread wear pattern, and whether all four tires are the correct size for the wheels fitted to the car. On this model, that means confirming you are not mixing up the 255/45R18, 255/40R19, and 265/35R20 fitments.

It is also wise to look for sidewall cuts, impact bubbles, or evidence of long storage, especially if the car is not driven often. A short pre-drive inspection takes only a few minutes and is one of the simplest ways to avoid vibration, poor handling, or a more serious tire failure.

Any Audi A7 Quattro should be driven within the capability of the exact tires fitted, using the size and service description on the sidewall as the controlling reference rather than assuming every tire in a given wheel diameter has the same limit. The listed products include modern radial performance tires, but condition and fitment remain just as important as nominal speed capability.

For real-world use, the sensible approach is to match speed to road conditions, tire condition, and proper inflation, especially on a car that may spend periods in storage. Even a high-performance touring car like the Audi A7 Quattro should not be pushed hard on aged, damaged, or mismatched tires.
