2017 Audi S6 Tires

The 2017 Audi S6 uses two primary tire sizes: 255/40R19 and 255/35R20. Both are radial sizes, and the correct one depends on whether the car is equipped with 19-inch or 20-inch wheels rather than on a unique trim-only fitment difference.

Choosing between them starts with checking the actual wheel diameter on the car. Even though Premium Plus and Prestige can use the same two sizes, the tire must match the wheel already in place. Once that is confirmed, compare brands, tire series, sidewall style, and rim-width specifications within the correct size instead of treating the two sizes as interchangeable.

A 2017 Audi S6 uses either a 19-inch rim with 255/40R19 tires or a 20-inch rim with 255/35R20 tires. Both sizes are part of this model's fitment pattern, so the wheel diameter on the individual car is the deciding factor.

A quick wheel check prevents ordering the right section width in the wrong diameter. The two tire sizes share the same nominal 255-millimeter width and similar overall diameter, but they are built for different rims. Verifying the wheel first also helps when comparing product details such as recommended rim-width range, sidewall treatment, and the overall style of tire that best suits the car.

Premium Plus and Prestige do not have exclusive tire sizes in this application. Both 2017 Audi S6 sub-models can use 255/40R19 or 255/35R20, with the actual fitment determined by the wheel setup on the car rather than by the trim badge alone.

That means trim name by itself is not enough to select a tire. Check the current wheel diameter or confirm the original wheel package before choosing between the 19-inch and 20-inch sizes. After that, the shopping decision becomes much more specific: blackwall versus redline or raised white letter, brand preference, and which tire series matches the intended look and use.

Start with the basics: the car must be on 20-inch wheels, and the tire should be selected in the proper 255/35R20 radial size. From there, useful points of comparison include brand, tire series, sidewall style, rim-width range, weight, and any stated load specification tied to that specific product.

This size gives the S6 a distinctly low-profile presentation, so many buyers focus on both appearance and use. BFGoodrich, Nitto, and Pro-Trac options bring different series names and sidewall treatments, including blackwall, raised white letter, and redline. Matching the tire to the car's current wheel setup and intended road use is more important than choosing by appearance alone.

The available sidewall styles for 2017 Audi S6 tires include blackwall, RWL, and redline, depending on the exact tire size and product selected. Those choices appear across both 255/35R20 and 255/40R19 fitments, giving the car anything from a more understated modern look to a more custom visual treatment.

Sidewall style does not change the need to stay with the correct size for the wheel diameter. It is best treated as an appearance decision after fitment is locked in. Blackwall works naturally for a contemporary factory-inspired presentation, while redline or raised white letter can push the car in a more personalized direction without changing the underlying radial size requirement.

Tires for the 2017 Audi S6 are available from BFGoodrich, Nitto, and Pro-Trac in the applicable 255/35R20 and 255/40R19 sizes. The available series include g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III.

The practical difference is not simply the brand name, but how each option is presented within the correct size. Some choices focus on a blackwall performance look, while others add redline or raised white letter styling. Compare the tire within the exact 19-inch or 20-inch fitment first, then use series, sidewall style, rim-width specification, and other product details to narrow the selection.

On a 2017 Audi S6, the primary fitments are radial tires, so the main appearance difference comes less from construction changes and more from sidewall profile, wheel diameter, and sidewall styling. A 255/35R20 creates a lower-profile 20-inch presentation, while a 255/40R19 gives a slightly fuller sidewall on a 19-inch wheel.

Visual character also changes with the sidewall itself. Blackwall keeps the car closer to a clean modern sport-sedan look, while redline or raised white letter options create a more customized appearance. Since this is a modern performance sedan, keeping the correct size-to-wheel relationship is the first step in preserving the car's intended stance and overall balance.

Correct tire fitment matters because the 2017 Audi S6 depends on the relationship between wheel diameter, section width, and sidewall profile to maintain its visual proportion. Using 255/40R19 on a 19-inch wheel or 255/35R20 on a 20-inch wheel keeps the car within its established fitment pattern.

For an appearance-focused build, the next decisions are sidewall style and tire series rather than changing to an unrelated size. A blackwall tire keeps things subtle, while redline or raised white letter versions lean more custom. If originality is especially important, compare the current wheel and tire presentation to vehicle-specific references before moving away from the established fitment sizes.

Yes. A 2017 Audi S6 can be sensitive to fitment changes if it has aftermarket wheels, altered offset, suspension modifications, or body changes. The correct starting sizes remain 255/40R19 for 19-inch rims and 255/35R20 for 20-inch rims, but any change in wheel or chassis setup can alter clearance.

That makes it important to check more than tire size alone. A modified car should be reviewed for wheel width, steering clearance, inner-fender space, and suspension travel before new tires are installed. Even when the tire size appears correct on paper, changes elsewhere on the car can affect how comfortably that tire works in real driving conditions.

Before road use, inspect wheel condition, tire pressure, valve stems, and overall clearance at full steering lock. It is also smart to look over the suspension and alignment condition, since uneven wear or instability can shorten tire life quickly on a high-performance sedan like the 2017 Audi S6.

A short initial drive can reveal vibration, rubbing, or pull that should be addressed before regular use. Recheck inflation after installation and confirm there is no contact with suspension components or bodywork. On a car with 19-inch or 20-inch fitment options, making sure the installed tire matches the actual wheel diameter is one of the most basic but most important checks.

Tires on a 2017 Audi S6 should be inspected regularly for tread wear, air loss, cuts, bulges, and sidewall damage. Monthly pressure checks are a sensible routine, and a closer inspection before longer drives helps catch issues early, especially on a car that may see spirited driving or extended highway use.

Inspection matters just as much on low-mileage cars as on daily drivers. A performance sedan can hide tire aging if the tread still looks good, so condition should be judged by the whole tire, not tread depth alone. Keeping the tires properly inflated and watching for uneven wear also helps confirm that alignment and suspension condition remain compatible with the car's wheel-and-tire setup.
