2013 Audi A7 Quattro Tires

The 2013 Audi A7 Quattro uses three primary tire sizes: 255/45R18, 255/40R19, and 265/35R20. All three are radial metric sizes, but they do not apply interchangeably across every configuration because the car was fitted with different wheel diameters depending on sub-model and wheel package.

The practical step is to confirm the wheel diameter already on the car before selecting a tire. A Base model may be on either 18-inch or 19-inch wheels, while the 20 Inch Option uses the 20-inch size. Once that is confirmed, the choice shifts from fitment to comparing sidewall style, tire series, brand, and wheel-width compatibility.

The 2013 Audi A7 Quattro uses 18-inch, 19-inch, or 20-inch rims depending on configuration. The 255/45R18 size matches an 18-inch rim, 255/40R19 matches a 19-inch rim, and 265/35R20 matches a 20-inch rim.

That rim diameter is the first fitment point to verify, especially on a car that may have had wheels changed over time. Looking only at the badge or trim name is not enough if aftermarket wheels have been installed. Check the wheel itself and the tire sidewall before ordering, then compare the appropriate radial choices within that exact diameter.

More than one tire size appears on the 2013 Audi A7 Quattro because the model was offered with different wheel diameters. The Base configuration uses either 255/45R18 or 255/40R19, while the 20 Inch Option uses 265/35R20.

Those sizes are tied to wheel package, not just appearance, so the correct tire starts with the wheel currently on the vehicle. Even though the overall tire diameters are close, the rim diameter and profile are different. Tire selection should follow the actual wheel setup first, then move to preferred brand, sidewall treatment, and tire series.

Start with the correct size for the wheel diameter on the car: 255/45R18, 255/40R19, or 265/35R20. From there, compare radial construction details that affect your buying decision, including brand, tire series, sidewall style, rim-width suitability where stated, and product characteristics such as load capacity or tire weight when those details matter to your setup.

The best choice depends on whether the goal is a restrained blackwall presentation or a more custom look with redline or raised white letter styling. Wheel diameter, intended road use, and the vehicle’s current setup all matter. A careful comparison keeps the car within the proper size family while letting appearance and product features guide the final selection.

Tires for the 2013 Audi A7 Quattro are available in blackwall, redline, and RWL sidewall styles, depending on size and series. Blackwall choices appear across BFGoodrich and Nitto offerings, while Pro-Trac Street Pro III adds redline and RWL options in the applicable 18-inch, 19-inch, and 20-inch sizes.

That gives the A7 owner a clear appearance choice without changing the underlying fitment size. Blackwalls maintain a more understated modern presentation, while redline and raised white letter styles create a more customized look. The important thing is to select the preferred sidewall treatment only after confirming the correct size and wheel diameter already on the car.

BFGoodrich, Nitto, and Pro-Trac all offer tires for the 2013 Audi A7 Quattro in the applicable radial sizes. Depending on the wheel diameter, the available lineup includes BFGoodrich g-Force series products, Nitto NT555 G2, and Pro-Trac Street Pro III.

Brand choice is only one part of the decision, because the actual options also vary by size, series, and sidewall style. Some buyers will focus on blackwall performance-style tires, while others may want redline or RWL styling. It makes sense to narrow the search by wheel diameter first, then compare the brands that are available in that exact fitment.

A period-style approach on a 2013 Audi A7 Quattro starts with keeping the correct wheel diameter and tire size already associated with the car’s configuration. From there, the visual direction comes from the tire series and sidewall treatment, with blackwall choices preserving a restrained contemporary look and redline or RWL options creating a more individualized presentation.

Because this is a modern luxury sport sedan rather than a traditional restoration-era car, appearance usually revolves around preserving the original overall stance rather than chasing a single historically fixed sidewall style. Matching the right size to the existing wheels is the foundation. After that, the owner can choose whether the goal is subtle factory-inspired appearance or a more custom visual statement.

On the 2013 Audi A7 Quattro, construction is straightforward because the primary fitments are radial. That means the appearance difference comes less from bias-ply versus radial decisions and more from profile, wheel diameter, sidewall style, and the visual character of the tire series chosen in 18-inch, 19-inch, or 20-inch form.

A lower-profile 20-inch setup naturally looks more aggressive, while the 18-inch and 19-inch combinations maintain a fuller sidewall. Sidewall treatment also changes the visual tone immediately. For an owner trying to keep the car close to its original era, preserving the correct size and wheel relationship usually matters more than adding a novelty sidewall treatment that alters the overall character.

Yes. Modifications can change tire fitment on a 2013 Audi A7 Quattro even when the tire size seems close to a standard option. Aftermarket wheels, altered wheel width, offset changes, suspension lowering, or body modifications can all affect whether an 18-inch, 19-inch, or 20-inch tire setup has proper clearance.

A car that no longer has its original wheel package should be checked carefully before choosing tires by catalog size alone. Measure the actual wheel diameter and width, inspect clearance at full steering lock, and look at fender and suspension space under load. That extra verification matters most when moving between the vehicle’s three different wheel-diameter families.

Before driving a 2013 Audi A7 Quattro on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and make sure the tires are mounted and inflated properly. It also helps to check for suspension wear, alignment issues, and any signs that the previous tires were rubbing or wearing unevenly.

A short inspection drive should include listening for rubbing, feeling for vibration, and checking that steering response is normal. Recheck pressure after the first few drives and look over the sidewalls and tread for any unusual contact marks. On a modern performance-oriented sedan like the A7, small fitment issues are easier to catch early than after miles of use.

Tires on a 2013 Audi A7 Quattro should be inspected regularly, not just when tread looks low. A quick visual check for cuts, bulges, cracking, embedded debris, and uneven wear is worth doing often, especially on a car with low-profile 19-inch or 20-inch tires where impacts and edge wear can become noticeable sooner.

Pressure should also be checked routinely because correct inflation supports both wear and drivability. Cars that sit for longer periods still need inspection, since age and storage conditions affect tires even when mileage stays low. Looking over the tires before a longer drive and after any pothole strike or curb contact is a sensible habit on this Audi.
