The 2009 Audi TTS Quattro sits at the sharper edge of the Mk2 TT lineup, blending compact sports-car proportions with turbocharged performance and Audi’s all-wheel-drive character. It is a modern enthusiast car, but one where wheel and tire choice still plays a major role in preserving the balance between appearance, grip, and everyday drivability. This model uses radial tires in either 245/40R18 or 255/35R19, so the first step is confirming which wheel package is on the car. From there, the real choice is between blackwall sport tires or more appearance-driven options such as redline or raised white letter styling in the 18-inch size.
Which Tire Size Is Right for The 2009 Audi TTS Quattro
The 2009 Audi TTS Quattro uses two primary tire sizes, and the correct one depends on which wheel diameter is on the car. Both fitments are radial, but one uses an 18-inch rim and the other uses a 19-inch rim, so confirming the wheel size comes first before comparing tire series, sidewall style, or overall product type.
A 245/40R18 tire uses a 245-millimeter section width, a 40-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 2009 Audi TTS Quattro, this size supports a modern performance-oriented setup while still leaving room for different tire personalities within the same fitment. Available choices include blackwall sport radials from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, plus redline and raised white letter treatments in the Pro-Trac Street Pro III line. This size is the one to evaluate if the car is on 18-inch wheels and the goal is balancing correct fitment with either contemporary or more distinctive styling.
A 255/35R19 tire uses a 255-millimeter section width, a 35-series aspect ratio, radial construction, and a 19-inch rim diameter. For the 2009 Audi TTS Quattro, this fitment belongs to the 19-inch wheel setup and carries a slightly lower-profile presentation than the 18-inch size. Available options in this size center on blackwall performance tires from BFGoodrich across several g-Force series. This is the size to consider when the car already wears 19-inch wheels and the priority is staying with the proper rim diameter while comparing series details and wheel-width compatibility.
Sub-model fitment is straightforward here because the covered 2009 Audi TTS Quattro Base can use either of the two primary tire sizes. The key step is not trim identification so much as confirming whether the car has the 18-inch or 19-inch wheel setup before choosing a tire.

Tire Size & Fitment
What tire size fits a 2009 Audi TTS Quattro?
The 2009 Audi TTS Quattro uses two primary tire sizes: 245/40R18 and 255/35R19. Both are radial fitments, but they do not serve the same wheel package because one is built for an 18-inch rim and the other for a 19-inch rim.
The practical question is not which size is better, but which wheel diameter is already on the car. Checking the current wheel size, reading the tire sidewall, and confirming the vehicle has not been changed to aftermarket wheels will keep the selection process focused on the correct fitment.
What size rim does a 2009 Audi TTS Quattro use?
A 2009 Audi TTS Quattro uses either an 18-inch or 19-inch rim, depending on which of its two factory-size tire fitments is on the car. The 245/40R18 size belongs on an 18-inch rim, while the 255/35R19 size belongs on a 19-inch rim.
Rim diameter should be confirmed before anything else, because a tire for one diameter cannot be mounted on the other. Wheel width also matters once the diameter is known, especially when comparing performance tire options that carry their own approved rim-width ranges.
Why does the 2009 Audi TTS Quattro have more than one tire size?
The 2009 Audi TTS Quattro has more than one tire size because it can be equipped with two different wheel diameters. One setup uses 245/40R18 tires, and the other uses 255/35R19 tires, both in radial construction.
That means tire choice follows the wheel package rather than a broad year-make-model rule alone. Looking at the car itself is important, especially if it has changed hands or been modified, since replacement tires should match the actual rim diameter and overall wheel setup now on the vehicle.
Choosing the Right Tire
What should I consider when choosing a 245/40R18 or 255/35R19 tire for a 2009 Audi TTS Quattro?
Start with the correct primary size for the car’s wheel diameter, then compare construction, tire series, sidewall style, and wheel-width compatibility within that size. On the 2009 Audi TTS Quattro, both listed fitments are radial, so the main decision is matching the actual wheel package and the kind of driving or appearance the owner wants.
An 18-inch setup opens up more variation, including blackwall, redline, and raised white letter choices, while the 19-inch size stays more focused on blackwall sport tires. Looking at rim-width recommendations, load figures where given, and whether the car is street-driven or used more aggressively will help narrow the options.
What sidewall styles are available for 2009 Audi TTS Quattro tires?
Blackwall is available in both primary sizes for the 2009 Audi TTS Quattro. In the 245/40R18 size, there are also redline and RWL, or raised white letter, sidewall treatments through the Pro-Trac Street Pro III line.
Sidewall style changes the visual character of the car more than the fitment itself, so the right choice depends on whether the goal is a clean modern look or a more distinctive custom presentation. The sidewall style still needs to be selected within the correct tire size and wheel diameter already on the car.
What brands offer tires for the 2009 Audi TTS Quattro?
Available brands for the 2009 Audi TTS Quattro include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac. The broadest selection appears in 245/40R18, while 255/35R19 centers on BFGoodrich performance tire offerings.
Brand alone should not drive the choice. It makes more sense to compare the size needed, the tire series within that brand, the sidewall style offered, and the wheel-width range the tire is intended to work with, especially on a performance car where wheel and tire balance matters.
Restoration & Appearance
Which tire should I choose for a period-style 2009 Audi TTS Quattro?
A period-style approach for a 2009 Audi TTS Quattro usually starts by keeping the correct wheel diameter and matching tire size already associated with the car, either 245/40R18 or 255/35R19. Since this is a modern performance Audi, the most natural visual starting point is a radial tire that keeps the proper low-profile sport-car stance.
Appearance then comes down to presentation within the right fitment. Blackwall keeps the look closest to a contemporary factory-era sports coupe, while the 245/40R18 size also allows more expressive redline or raised white letter options for an owner who wants a custom visual twist without changing the base size.
How does tire construction affect the appearance of a restored 2009 Audi TTS Quattro?
Tire construction does not create a bias-ply versus radial decision on the 2009 Audi TTS Quattro, because its primary fitments are already radial. The visual effect comes more from the tire’s proportions, wheel diameter, and sidewall treatment than from a construction change between vintage and modern formats.
Keeping the correct 18-inch or 19-inch fitment helps preserve the car’s intended stance and wheel-to-fender relationship. Once that is settled, blackwall gives the cleanest modern presentation, while redline or raised white letter in the 18-inch size can shift the look toward a more personalized enthusiast style.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Audi TTS Quattro?
Yes. Modifications can affect tire fitment on a 2009 Audi TTS Quattro, especially if the car has aftermarket wheels, altered suspension height, spacers, or body changes that influence clearance. Even when the tire size matches one of the recognized primary fitments, wheel width and the overall setup can still change how the tire sits on the car.
A modified TTS should be checked for inner clearance, fender clearance, and steering travel before a new set is chosen. Confirming the actual wheel diameter and width on the car is especially important here, because the model uses both 18-inch and 19-inch fitments depending on configuration.
What should I inspect before driving a 2009 Audi TTS Quattro on new tires?
Before driving a 2009 Audi TTS Quattro on new tires, inspect the wheel diameter and width, verify the tire size matches the wheel package, and look over the suspension and alignment condition. Tire pressure should also be set correctly, and the wheels themselves should be checked for damage or past repair issues.
After installation, pay attention to fender and suspension clearance, especially at full steering lock and over bumps. A short initial drive can reveal rubbing, vibration, or balance concerns early, which is particularly useful on a performance-oriented car where tire choice and wheel setup have a strong effect on road feel.
How often should tires on a 2009 Audi TTS Quattro be inspected?
Tires on a 2009 Audi TTS Quattro should be inspected regularly, not just when tread looks worn. A quick visual check for cuts, bulges, cracking, uneven wear, and air loss is smart before routine driving, and a more careful inspection makes sense before longer trips or after the car has been stored.
Performance cars can reveal alignment or suspension issues through tire wear faster than many ordinary vehicles. Looking over the tires whenever pressures are checked helps catch shoulder wear, center wear, or damage early, and it also confirms that the tire still matches the wheel and fitment setup currently on the car.
