2016 Audi S4 Tires

A 2016 Audi S4 uses one of two radial tire sizes: 245/40R18 or 255/35R19. The 245/40R18 size belongs to standard 18-inch wheel configurations, while 255/35R19 is used on S4 models equipped with the 19-inch option package.

The key is matching the tire to the wheel diameter already on the car rather than choosing by appearance alone. An S4 with 18-inch wheels needs the 18-inch size, and a 19-inch option car needs the 19-inch size. If the car has been modified or fitted with different wheels, confirm the actual wheel diameter and width before selecting tires.

The 2016 Audi S4 uses either an 18-inch or 19-inch rim, depending on configuration. Cars with 245/40R18 tires use 18-inch rims, while cars equipped with 255/35R19 tires use 19-inch rims.

Rim diameter is the first fitment detail to verify because the two tire sizes are built for different wheels. Tire choice should also account for wheel width, since available products in these sizes are designed around specific width ranges. A quick check of the wheel markings or a direct measurement helps prevent ordering a tire for the wrong S4 wheel package.

No. The 2016 Audi S4 Premium Plus and Prestige use 245/40R18 in standard form, while Premium Plus (19 Inch Option) and Prestige (19 Inch Option) use 255/35R19. The difference is tied to the wheel package, not just the trim name alone.

That means the exact sub-model description matters before comparing tires. A Premium Plus or Prestige badge by itself does not guarantee the same fitment if the car has the optional 19-inch setup. Looking at the wheel diameter on the car is often the fastest way to confirm which size belongs on that specific S4.

Start with the correct size for the car's wheel package: 245/40R18 for 18-inch setups or 255/35R19 for 19-inch option cars. From there, compare radial tire construction, rim-width compatibility, load figures where stated, and the intended use of the car, whether that means regular street driving or a more specialized performance application.

Selection also depends on the character you want from the tire. Some choices focus on modern street performance, while others add a more customized visual treatment such as redline or raised white letter sidewalls in 18-inch fitment. Matching the tire to both the wheel and the role of the car usually leads to a better result than choosing by brand name alone.

Sidewall choice varies by size. Blackwall options are available in both 245/40R18 and 255/35R19, while the 245/40R18 fitment also includes redline and RWL, or raised white letter, choices through the Pro-Trac Street Pro III line.

That makes the 18-inch fitment the more flexible choice if appearance matters as much as size. Blackwall generally keeps the look closer to contemporary sport-sedan styling, while redline and raised white letter sidewalls create a more personalized presentation. The right decision depends on whether the goal is a restrained OEM-style look or a more noticeable custom accent.

Tires for the 2016 Audi S4 are available from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, depending on size. The 245/40R18 fitment has the broadest brand spread, while 255/35R19 centers on BFGoodrich performance options.

Brand alone should not be the only filter. It helps to compare each tire's series, sidewall treatment, rim-width range, and intended use within the correct S4 size. That approach is especially useful on the 18-inch setup, where the available mix includes both street-oriented performance tires and a drag-focused radial choice with a very different purpose.

A period-style approach for a 2016 Audi S4 usually starts by staying with the correct original fitment format for the car's wheel package: 245/40R18 on 18-inch cars or 255/35R19 on 19-inch option cars. Since this is a modern sport sedan, the period look is still rooted in low-profile radial construction rather than vintage-style bias-ply design.

Appearance then comes down to how close you want the tire to remain to contemporary Audi sport-sedan presentation. Blackwall tires preserve the cleanest look, while the 18-inch fitment opens the door to redline or raised white letter styling for a more customized feel. Buyers chasing exact delivery-day authenticity should also compare against original vehicle literature and wheel specifications.

On a 2016 Audi S4, construction is straightforward because the correct primary fitments are radial tires in both available sizes. That keeps the visual character aligned with the car's modern chassis and wheel proportions, especially given the short sidewalls used on both the 18-inch and 19-inch packages.

The more noticeable appearance differences come from sidewall treatment and wheel package rather than a bias-ply-versus-radial decision. A blackwall tire supports a clean late-model sport sedan look, while 245/40R18 fitment also offers redline and raised white letter alternatives for a less restrained presentation. Keeping the proper size is what protects the S4's intended stance most effectively.

Yes. A 2016 Audi S4 that has aftermarket wheels, suspension changes, spacers, or altered ride height may no longer behave exactly like a stock car when tire fitment is evaluated. Even when the tire size matches a known S4 fitment, the wheel's width and placement can change clearance at the fender, suspension, or steering components.

That matters most when moving between 18-inch and 19-inch wheel setups or when the car has been lowered. Verifying the actual wheel diameter, width, and tire-to-body clearance before installation helps avoid rubbing or mismatch problems. A careful visual check with the wheels turned lock to lock is a useful step on any modified S4.

Before driving a 2016 Audi S4 on new tires, inspect the wheel for damage, confirm the tire size matches the car's 18-inch or 19-inch setup, and make sure inflation is set appropriately for the tire and vehicle application. It is also wise to look for any signs of suspension wear that could affect alignment or early tire wear.

A short test drive should be followed by another quick inspection for air loss, rubbing, or uneven seating. Modern low-profile tires make proper installation and wheel condition especially important, because bent wheels or alignment issues can show up quickly in how the car tracks and how the tread begins to wear.

Tires on a 2016 Audi S4 should be checked regularly, especially because this car uses relatively low-profile performance sizes. Frequent visual inspections help catch uneven wear, cuts, bulges, punctures, and pressure loss before they become larger problems, whether the car is driven daily or only used occasionally.

A practical routine is to inspect the tires during normal washing or fueling and to take a closer look before longer trips. Cars that sit for extended periods still need attention, since age, underinflation, and flat spotting can affect road manners. Consistent checks are one of the simplest ways to protect both the tires and the S4's handling.
