Audi TTS Quattro Tires

Audi TTS Quattro uses four tire sizes across the 2009-2023 range covered here: 245/40R18 for 2009-2010, 255/35R19 for 2009-2015, 245/35R19 for 2016-2020, and 255/30R20 for 2016-2023. The corresponding rim diameters are 18 inches, 19 inches, 19 inches, and 20 inches. Early cars overlap between 18- and 19-inch fitments, and later cars overlap between 19- and 20-inch fitments.

That means year alone is not always enough to choose correctly. Start by checking the wheel diameter actually fitted to the car, then match the tire size to that wheel. On 2009-2010 cars, the decision is between 18 and 19 inches, while 2016-2020 cars need to be sorted between 19 and 20 inches. Once that is established, the correct size becomes much easier to identify.

On an Audi TTS Quattro, 255/30R20 is a modern metric radial size. The 255 is the nominal section width in millimeters, 30 is the aspect ratio that expresses sidewall height as 30 percent of section width, R means radial construction, and 20 is the required rim diameter in inches. Within this fitment range, that size appears on 2016-2023 applications.

The practical takeaway is that 255/30R20 is tied to a 20-inch wheel and a notably short sidewall. That combination affects visual stance and ride feel compared with the 19-inch alternatives. If your Audi TTS Quattro is from the 2016-2020 overlap years, do not assume the larger size simply because it is later production; verify the wheel itself before selecting tires.

A 2016 Audi TTS Quattro has two tire sizes listed because that model year appears with two different wheel diameters. The 19-inch setup uses 245/35R19, while the 20-inch setup uses 255/30R20. The split is a wheel-diameter difference rather than a different construction type, since the listed tires are radial in both sizes.

That distinction matters because a 19-inch tire cannot be fitted to a 20-inch wheel, and the reverse is equally true. The right way to sort a 2016 car is to read the tire sidewall currently on the car or measure the wheel diameter directly. If the car has aftermarket wheels, use the actual wheel and tire dimensions on the vehicle rather than assuming the original configuration.

Audi TTS Quattro uses 18-inch, 19-inch, and 20-inch rim diameters within the range covered here. The 18-inch size appears on 2009-2010 cars with 245/40R18, the 19-inch sizes appear on 2009-2015 and 2016-2020 cars with 255/35R19 or 245/35R19, and the 20-inch size appears on 2016-2023 cars with 255/30R20. The key production shift happens in 2016, when 20-inch fitment enters the range.

If you are standing beside the car and trying to order tires, rim diameter is the first specification to confirm. It determines which of the listed sizes can physically mount on the wheel. This is especially important on overlap years, because the same model year may legitimately appear with more than one wheel diameter depending on the specific configuration.

A 2010 Audi TTS Quattro appears with two listed sizes: 245/40R18 and 255/35R19. Those sizes correspond to different wheel diameters, so the car must be matched to either an 18-inch or 19-inch wheel before choosing tires. Both are legitimate 2010 fitments within this range.

The simplest approach is to read the existing tire sidewall if the car is already wearing the correct size. If that is uncertain, inspect the wheel diameter directly and compare it against the sizes above. On a modified car, rely on the wheel and tire currently fitted rather than model-year assumptions, because wheel changes are common on performance-oriented Audi TTS Quattro cars.

Audi TTS Quattro tire offerings here include blackwall across all listed sizes, with redline and RWL options appearing in 245/40R18 only. The 255/35R19 and 245/35R19 offerings shown are blackwall, while the 18-inch size is the only one that adds visible sidewall styling alternatives. That makes the 18-inch fitment the broadest choice if appearance is part of the decision.

For most Audi TTS Quattro owners seeking a contemporary, understated look, blackwall is the natural match. Redline and raised white letter styling create a more customized presentation and may suit a car built for a specific visual theme rather than factory-style appearance. Sidewall style should always be chosen after the correct size and rim diameter are settled, not before.

The listed Audi TTS Quattro tire options come from four brands: M&H Racemaster, BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears across multiple 18-inch and 19-inch applications, Nitto appears in 18-inch and 19-inch fitments, Pro-Trac appears in 245/40R18, and M&H Racemaster appears in 245/40R18. That gives the early 18-inch fitment the widest brand spread in this group.

Brand choice should be guided by how the car is used and by the exact size you need. Some sizes have several competing choices, while others are represented more narrowly. Once the correct size is identified, compare the available brands by tire series, sidewall style, and intended use so the final selection matches the role of your Audi TTS Quattro.

Audi TTS Quattro tire offerings here span several series, including Drag Radial, g-Force Comp 2 AS, g-Force Sport Comp 2, Nitto NT555 G2, g-Force Phenom T/A, and Street Pro III. All are radial tires, but they represent different use cases within the performance category, from street-oriented all-season or sport-focused designs to more specialized drag-oriented applications. The widest variety appears in 245/40R18, while the 19-inch sizes are more concentrated around blackwall performance radials.

That means the right series is not only a matter of size, but also of how the Audi TTS Quattro is driven. A car used mainly for fair-weather road miles may call for a different type of tire than one built around visual style or straight-line performance. After confirming fitment, compare the series names closely so the tire’s intended character aligns with the car’s actual use.

An Audi TTS Quattro stored on its tires should be kept in a cool, dry, dark space away from ozone sources such as electric motors, battery chargers, and welders. Clean the tires first, set inflation to the vehicle’s proper operating range, and avoid long-term exposure to direct sunlight or standing moisture. If storage will be extended, moving the car slightly from time to time helps reduce flat-spotting.

Performance tires with short sidewalls can still develop temporary shape set when a collector or enthusiast car sits for long periods. Tire cradles or periodic repositioning can help if the car is stored for a season at a time. Good storage habits preserve not only tread life, but also ride quality and appearance when the Audi TTS Quattro returns to the road.

Tires on an Audi TTS Quattro should be inspected at least monthly and again before any sustained drive. Check inflation, tread wear pattern, punctures, sidewall cuts, bulges, and any signs of age-related cracking. On a performance-oriented all-wheel-drive car, uneven wear is especially important to catch early because it can point to alignment issues or differences in effective tire diameter.

A low-mileage enthusiast car often ages its tires long before it wears them out. Frequent inspection helps you spot problems while they are still minor and before they affect handling or driveline behavior. If the Audi TTS Quattro has been sitting, take a close look before the first drive of the season rather than assuming the tires are fine because the tread still appears deep.

Tires on an Audi TTS Quattro should be replaced when they show cracking, impact damage, sidewall bulges, repeated air loss, irregular wear that cannot be corrected, or any age-related hardening that affects serviceability, even if tread depth still looks acceptable. Performance tires can become less compliant and less trustworthy with age long before the tread is gone. Replacement should be considered a condition-based decision, not just a tread-depth decision.

That matters on an enthusiast car because many Audi TTS Quattro examples cover limited annual mileage. A tire that looks cosmetically decent may still be too old or too compromised for confident use. Routine inspection by a knowledgeable tire professional is the best way to judge age and condition, particularly if the car has spent long periods parked or has an unknown recent service history.

The listed Audi TTS Quattro tires are modern radial products, and many are clearly street-oriented performance designs suitable for road use when they are the correct size for the wheel and are in proper condition. Safety depends on more than the size alone, however. The tire must match the wheel diameter, be correctly inflated, and be free from age or damage issues that can undermine performance.

For a car like the Audi TTS Quattro, road safety also depends on using a matched set appropriate to the vehicle’s handling and drivetrain demands. Avoid treating appearance or aggressive sizing as a substitute for correct fitment. If the car has been modified, verify wheel width, tire clearance, and overall condition carefully before regular road use.

Before driving an Audi TTS Quattro, check tire pressure, visible tread and sidewall condition, and whether all four tires are the correct sizes for the wheels fitted to the car. Also look for uneven wear, cuts, bulges, embedded objects, and any sign of rubbing in the wheelhouse. Because this fitment range includes multiple wheel diameters, confirming that each tire matches its wheel is fundamental.

A quick pre-drive inspection is especially worthwhile if the car is used only occasionally. Performance tires can lose pressure while parked, and an unnoticed issue can change steering feel and braking response very quickly. Spending a few minutes checking the tires before heading out is one of the simplest ways to protect both the Audi TTS Quattro and the driving experience it is meant to deliver.

An appropriate speed for an Audi TTS Quattro on correctly fitted tires is one that stays well within legal limits, road conditions, and the condition of the tires actually on the car. Even though several listed options are performance-oriented radials, real-world safe speed depends on age, inflation, suspension condition, alignment, and whether the tires are evenly matched across the car. A capable chassis does not reduce the importance of tire condition.

For collector-minded or low-use examples, the conservative approach is the right one. Bring the car up to speed gradually after storage, pay attention to vibration or tramlining, and reassess if anything feels abnormal. The Audi TTS Quattro may be designed for spirited driving, but tire age and condition should always set the practical limit rather than the car’s potential on paper.
