The 2009 Audi TT Quattro sits in the modern sport-compact luxury coupe era, where all-wheel-drive confidence and crisp chassis tuning were just as important as sharp styling. For many owners, it is a car that blends everyday drivability with a distinctly performance-focused feel. Tire fitment matters here because the 2009 Audi TT Quattro uses three radial sizes: 245/45R17, 245/40R18, and 255/35R19, with size choice tied to the exact sub-model and wheel package. Available tires range from blackwall performance radials to redline and raised white letter alternatives in certain sizes. The right choice starts with confirming the exact sub-model and wheel diameter before comparing appearance, series, and intended use.
Which Tire Size Is Right for The 2009 Audi TT Quattro
The 2009 Audi TT Quattro uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Both the 2.0T and 3.2 use either 245/45R17 or 245/40R18, while S Line versions use 255/35R19. Before choosing a tire, confirm whether the car has 17-inch, 18-inch, or 19-inch wheels and then match that to the correct sub-model fitment.
A 245/40R18 tire is a modern metric radial size with a 245-millimeter section width, a 40-series profile, and fitment for an 18-inch rim. On the 2009 Audi TT Quattro, this size suits non-S Line 2.0T and 3.2 configurations that use 18-inch wheels and keeps the fitment firmly in modern radial territory. Available choices include blackwall performance tires from BFGoodrich, Nitto, and M&H Racemaster, along with Pro-Trac options in redline and raised white letter form. This size makes sense when the car already wears 18-inch wheels and the goal is to compare performance-oriented radial options with some appearance variation.
A 245/45R17 tire uses the same 245-millimeter nominal width as the 18-inch option but pairs it with a 45-series profile on a 17-inch rim. For the 2009 Audi TT Quattro, it applies to non-S Line 2.0T and 3.2 versions equipped with 17-inch wheels, so it is not simply interchangeable with the 18-inch or 19-inch setups. Product choices include blackwall tires from BFGoodrich, Nitto, and M&H Racemaster, plus Pro-Trac Street Pro III versions with redline or raised white letter styling. This is the size to evaluate when the car retains 17-inch wheels and the buyer wants to compare both conventional blackwall and more distinctive sidewall treatments.
A 255/35R19 tire is a modern metric radial with a 255-millimeter section width, a lower 35-series profile, and fitment for a 19-inch rim. On the 2009 Audi TT Quattro, this size belongs to the 2.0T S Line and 3.2 S Line, making wheel diameter and trim identification especially important before selection. Available options are blackwall radials from BFGoodrich across several g-Force series, giving the size a more focused performance-style product mix than the 17-inch and 18-inch fitments. This size should be considered when the car is an S Line model or already carries the correct 19-inch wheel setup.
Sub-model fitment matters on the 2009 Audi TT Quattro because wheel and tire sizing is split between standard and S Line configurations. The first step is identifying whether the car is a 2.0T, 3.2, 2.0T S Line, or 3.2 S Line, then confirming the wheel diameter already on the vehicle.

2009 Audi TT Quattro 2.0T
The 2009 Audi TT Quattro 2.0T uses either a 245/45R17 or 245/40R18 radial, depending on the wheel setup. Tire selection starts with confirming whether the car has 17-inch or 18-inch wheels, then comparing blackwall performance tires or appearance-oriented sidewall options in the matching size.
The 2009 Audi TT Quattro 2.0T S Line uses a 255/35R19 radial fitment. That makes wheel confirmation straightforward, but it also means selection stays focused on 19-inch blackwall performance-style tires rather than the broader sidewall variety available in some smaller wheel sizes.
The 2009 Audi TT Quattro 3.2 uses either 245/45R17 or 245/40R18 radials, so the exact wheel diameter must be confirmed before ordering. Once the wheel size is settled, the choice becomes one of tire series, brand, and sidewall presentation within the correct radial size.
The 2009 Audi TT Quattro 3.2 S Line uses the 255/35R19 radial size. For this sub-model, the practical decision is less about multiple fitments and more about choosing among the available 19-inch blackwall tire series that suit the car's intended road use.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 2009 Audi TT Quattro?
The 2009 Audi TT Quattro uses three tire sizes: 245/45R17, 245/40R18, and 255/35R19. Non-S Line 2.0T and 3.2 models use either 245/45R17 or 245/40R18, while 2.0T S Line and 3.2 S Line models use 255/35R19.
The practical decision is identifying the exact sub-model and confirming the wheel diameter already on the car. A TT Quattro with 17-inch wheels needs a different tire than one with 18-inch or 19-inch wheels, even when the overall vehicle looks similar at a glance.
What size rim does a 2009 Audi TT Quattro use?
A 2009 Audi TT Quattro can use 17-inch, 18-inch, or 19-inch rims, depending on the sub-model and wheel package. The 245/45R17 size fits a 17-inch rim, 245/40R18 fits an 18-inch rim, and 255/35R19 fits a 19-inch rim.
Wheel diameter should be confirmed before anything else because the tire size must match the rim exactly. Checking the current wheel size on the car is especially important if the TT Quattro has changed hands, received aftermarket wheels, or no longer wears its original wheel-and-tire setup.
Why does the 2009 Audi TT Quattro have more than one tire size?
More than one tire size applies to the 2009 Audi TT Quattro because fitment changes with sub-model and wheel package. The standard 2.0T and 3.2 configurations use 17-inch or 18-inch sizes, while S Line versions move to a 19-inch fitment with 255/35R19.
That means tire selection is not just a matter of model year and nameplate. The car's exact trim and actual wheel diameter need to line up with the chosen tire size, especially on a vehicle that may have had wheels changed for style, replacement, or performance reasons.
Choosing the Right Tire
What should I consider when choosing a 2009 Audi TT Quattro tire?
Start with the correct size for the car's sub-model and wheel diameter, then compare the type of radial tire available in that fitment. The 2009 Audi TT Quattro has choices that range from performance street tires to drag-oriented radials, with some 17-inch and 18-inch options also offering redline or raised white letter sidewalls.
After the size is settled, look at intended use, sidewall appearance, load specification, and wheel-width compatibility where those figures are given. A street-driven TT Quattro, a weekend toy, and a car built for straight-line use can all point toward different product priorities within the same size.
What sidewall styles are available for 2009 Audi TT Quattro tires?
Blackwall is available across all three 2009 Audi TT Quattro tire sizes. In 245/45R17 and 245/40R18, there are also Pro-Trac Street Pro III options with redline and RWL sidewalls, while the 255/35R19 fitment stays with blackwall offerings.
That gives owners of 17-inch and 18-inch wheel setups more flexibility if appearance matters as much as fitment. On a car with 19-inch S Line fitment, the product mix is more strictly performance-oriented in visual presentation, so the comparison is mainly between tire series rather than sidewall treatment.
What brands offer tires for the 2009 Audi TT Quattro?
Tires for the 2009 Audi TT Quattro are available from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac. Brand availability varies by size, with the 19-inch 255/35R19 fitment centered on BFGoodrich, while the 17-inch and 18-inch sizes include the broadest mix.
The useful comparison is not just brand name but how each brand appears within the correct size and series. Some options lean toward performance street use, some emphasize drag-radial character, and some add visual distinction through redline or raised white letter sidewall styling.
Restoration & Appearance
Which tire should I choose for a period-style 2009 Audi TT Quattro?
A period-style approach on a 2009 Audi TT Quattro still begins with the correct modern radial size for the sub-model and wheel diameter. From there, 245/45R17 and 245/40R18 fitments offer the most visual flexibility because blackwall, redline, and raised white letter options are available.
The choice depends on whether the goal is a more understated factory-inspired look or a customized presentation that reflects enthusiast taste from the era. Since exact originality can vary by wheel package and market, appearance-driven buyers should also compare the current wheels on the car before finalizing a tire style.
How does tire construction affect the appearance of a restored 2009 Audi TT Quattro?
On the 2009 Audi TT Quattro, primary fitment remains fully radial across all supported sizes, so construction choice is less about bias-ply versus radial appearance and more about sidewall styling within a radial tire. Blackwall gives the cleanest modern presentation, while redline and raised white letter options create a more assertive visual statement.
That matters most on 17-inch and 18-inch applications, where those appearance choices are available. A restoration-minded or preservation-focused owner will usually want the tire's profile, sidewall treatment, and wheel diameter to stay visually consistent with the character of the car rather than forcing a mismatched look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Audi TT Quattro?
Yes. Modifications can affect tire fitment on a 2009 Audi TT Quattro even when the tire size looks close to stock. Aftermarket wheels, suspension changes, ride-height adjustments, and body alterations can all change the clearance relationship between the tire, fender, and steering components.
That is why the actual wheel diameter and width on the car should be checked before choosing among 17-inch, 18-inch, or 19-inch fitments. A modified TT Quattro may need closer attention to clearance at full lock and through suspension movement than a car that remains in standard configuration.
What should I inspect before driving a 2009 Audi TT Quattro on new tires?
Before driving a 2009 Audi TT Quattro on new tires, inspect wheel condition, valve stems, tire pressure, and the basic alignment and suspension state of the car. It also helps to confirm that the new tires match the vehicle's actual wheel diameter and that there is no rubbing at normal steering angles.
A careful road-use check should include looking for clearance issues, unusual vibration, and signs of uneven contact once the car is back on the ground. On a performance-oriented car like the TT Quattro, worn suspension parts or damaged wheels can undermine the benefit of a correctly sized new tire.
How often should tires on a 2009 Audi TT Quattro be inspected?
Tires on a 2009 Audi TT Quattro should be inspected regularly for pressure loss, uneven wear, cuts, bulges, and sidewall cracking. Cars that see seasonal use, long storage periods, or spirited driving deserve closer attention because issues can develop even when tread depth still appears acceptable.
A quick visual check before routine drives is smart, and a more careful inspection is worthwhile before highway travel or after the car has been parked for an extended period. Performance-oriented fitments also benefit from periodic rotation and alignment review when the tire type and setup allow for it.
