2017 Audi A6 Quattro Tires

The 2017 Audi A6 Quattro uses three primary tire sizes: 245/45R18, 255/40R19, and 255/35R20. All three are radial sizes, and the correct one depends on the sub-model and wheel package already on the car rather than a single universal fitment across every version.

The practical first step is checking the exact trim and the actual wheel diameter mounted on the vehicle. An A6 Quattro on 18-inch wheels needs a different tire than one on 19-inch or 20-inch wheels, so using the current wheel setup as the starting point prevents confusion before comparing brands, tire series, or sidewall style.

A 2017 Audi A6 Quattro can use 18-inch, 19-inch, or 20-inch rims, depending on the tire size fitted to the car. The three primary pairings are 245/45R18 on an 18-inch rim, 255/40R19 on a 19-inch rim, and 255/35R20 on a 20-inch rim.

Rim diameter should be confirmed before looking at tire options because these sizes are not interchangeable across different wheel diameters. Once rim diameter is settled, it also helps to compare the wheel’s actual width to the tire’s rim-width range so the new tire suits both the wheel and the way the car is currently configured.

No. The 2017 Audi A6 Quattro Competition uses 255/35R20, while the Premium, Premium Plus 2.0, Premium Plus 3.0, and Prestige trims can use 245/45R18, 255/40R19, or 255/35R20. That means fitment is not identical across every covered sub-model.

This matters because choosing by model name alone can still leave you with the wrong tire size if the wheel package differs from another A6 Quattro of the same year. A quick check of the sub-model, wheel diameter, and current tire sidewall marking is the best way to narrow the correct fitment before comparing tire designs.

Start with the correct primary size for the car: 245/45R18, 255/40R19, or 255/35R20. From there, compare construction details that matter for a modern sport-luxury sedan, including rim-width compatibility, tire series, sidewall style, and any load information attached to a specific product.

Appearance and use matter just as much as raw size. A blackwall tire keeps a contemporary look, while raised white letter or redline options on some 19-inch and 20-inch sizes add a more customized presentation. It also helps to think about whether the car is primarily a daily road car, a fair-weather cruiser, or a modified sedan with a distinct visual direction.

Sidewall style depends on size. Blackwall options are available across all three primary sizes, while the 255/40R19 and 255/35R20 fitments also include raised white letter and redline choices through the Street Pro III series from Pro-Trac.

That gives the 19-inch and 20-inch setups a broader appearance range than the 18-inch fitment. Buyers who want the car to retain a more understated modern look will usually focus on blackwalls, while those building a more personalized visual statement may prefer the extra sidewall character offered by raised white letter or redline tires.

The 2017 Audi A6 Quattro tire selections here come from BFGoodrich, Nitto, and Pro-Trac, depending on size. BFGoodrich appears across all three fitments with several g-Force series choices, Nitto is available in 18-inch and 20-inch sizes through the NT555 G2 line, and Pro-Trac appears in 19-inch and 20-inch applications.

Brand choice should be compared alongside the exact tire series, sidewall treatment, and wheel match rather than treated as a shortcut by itself. Two tires in the same size can still differ in presentation, rim-width range, weight, and load details, so the best comparison is always made within the correct size for the car’s wheel setup.

A period-style approach on a 2017 Audi A6 Quattro starts with keeping the correct wheel diameter and primary tire size already associated with the car, whether that is 245/45R18, 255/40R19, or 255/35R20. Since this is a modern luxury-performance sedan, the appearance question is less about vintage construction and more about maintaining the right stance and proportion.

For a cleaner, more original-looking presentation, blackwall tires are the natural direction. If the car has been personalized or leans toward a more custom style, raised white letter or redline options in the 19-inch and 20-inch sizes can shift the look significantly. Exact originality questions are best checked against window-sticker, delivery, or marque-specific records for that individual car.

On the 2017 Audi A6 Quattro, construction does not create the old bias-ply-versus-radial appearance decision seen on earlier collector cars because the primary fitments here are all radial. The visual difference comes more from tire profile, wheel diameter, and sidewall treatment than from switching between construction types.

That makes size discipline especially important. An 18-inch, 19-inch, or 20-inch setup changes the car’s visual balance, and within those sizes a blackwall, redline, or raised white letter sidewall can push the final look in very different directions. Buyers aiming for a restoration-minded presentation usually benefit from matching the tire to the car’s existing wheel package first.

Yes. A 2017 Audi A6 Quattro with aftermarket wheels, suspension changes, altered ride height, or body modifications can require more care than a stock example, even when the tire size looks close to one of the primary fitments. Wheel diameter, wheel width, and the tire’s section width all play into the final result.

That is why the current setup should be checked rather than assuming every A6 Quattro will accept the same tire choice. Look at actual wheel size, verify clearance at full steering lock, and inspect inner-fender and suspension space before changing size or profile. Those checks matter most when moving between 18-inch, 19-inch, and 20-inch wheel packages.

Before road use, inspect inflation pressure, confirm that each tire matches the intended size, and look over the wheels for damage or improper seating. It also makes sense to check tread and sidewalls for cuts, bulges, or shipping damage, even when the tires are new and have not yet seen regular mileage.

A modern sedan like the 2017 Audi A6 Quattro also benefits from a quick review of alignment condition and suspension health, especially if the previous tires showed uneven wear. On cars with larger 19-inch or 20-inch wheel packages, extra attention to curb damage and clearance can help prevent vibration, rubbing, or avoidable wear once the car is back on the road.

Tires on a 2017 Audi A6 Quattro should be inspected regularly, not just when tread depth becomes a concern. A routine visual check for pressure loss, uneven wear, punctures, cracking, and sidewall damage helps catch problems early, particularly on a vehicle that may alternate between daily use and longer highway drives.

Inspections are especially useful after seasonal storage, wheel changes, or suspension work. It is also smart to recheck the tires before a longer trip, paying attention to inflation, wheel condition, and any signs of rubbing or abnormal wear. Staying ahead of those small issues helps preserve the intended ride quality and fitment of the selected tire size.
