The 2010 Audi TTS Quattro sits in the modern performance era where compact dimensions, turbocharged power, and all-wheel-drive traction defined the appeal of a serious everyday sports coupe or roadster. Tire choice matters on this car because the chassis is tuned around low-profile radial fitments rather than vintage-style sizing. This model uses either 245/40R18 or 255/35R19 radial tires, so the first step is confirming which wheel package is on the car. From there, the real choice is between 18-inch and 19-inch fitment, along with differences in tire series, sidewall presentation, and intended use. A stock example and a modified one may need very different verification before replacement.
Which Tire Size Is Right for The 2010 Audi TTS Quattro
The 2010 Audi TTS Quattro uses two primary tire sizes, and the difference comes down first to wheel diameter. One fitment uses an 18-inch rim and the other uses a 19-inch rim, with both built as modern radial performance tires. Before choosing a replacement, confirm which wheel setup is actually on the car, especially if it has changed hands or received aftermarket wheels.
245/40R18 is a modern metric radial size in which 245 represents the nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 18 is the rim diameter in inches. On the 2010 Audi TTS Quattro, this size suits the 18-inch wheel setup and keeps the car in a contemporary low-profile performance format. Available choices include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, with sidewall options such as blackwall, redline, and raised white letter. This size is the one to evaluate if your car is on 18-inch wheels and you want to compare street, appearance-driven, or specialty radial options.
255/35R19 follows the same modern metric radial format, with a 255-millimeter nominal section width, a 35-series profile, radial construction, and a 19-inch rim diameter. For the 2010 Audi TTS Quattro, this size belongs to the 19-inch wheel fitment and carries an even lower-profile look than the 18-inch setup. Available products center on BFGoodrich performance-oriented series in blackwall form, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. This is the size to pursue when the car is equipped with 19-inch wheels and the goal is a performance radial in the proper rim diameter.
Sub-model fitment is straightforward here because the 2010 Audi TTS Quattro Base uses both primary tire sizes depending on wheel setup. The key check is not trim level but whether the car is wearing 18-inch or 19-inch wheels before selecting a tire.

Tire Size & Fitment
What tire size fits a 2010 Audi TTS Quattro?
The 2010 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 right choice depends on the wheels actually installed on the car. A TTS that still wears its original wheel package needs the matching size, while a car with replacement or aftermarket wheels should have wheel diameter and width confirmed before ordering tires.
What size rim does a 2010 Audi TTS Quattro use?
A 2010 Audi TTS Quattro uses either an 18-inch or 19-inch rim, depending on which tire size is on the car. The 245/40R18 fitment uses an 18-inch rim, while the 255/35R19 fitment uses a 19-inch rim.
That rim-diameter difference matters more than anything else when replacing tires. Check the wheel itself, the current tire sidewall, and the overall setup before selecting a replacement, because the two tire sizes are matched to different wheel diameters and are not chosen interchangeably.
Why does the 2010 Audi TTS Quattro have more than one tire size?
The 2010 Audi TTS Quattro has more than one tire size because this model was fitted with two different wheel-diameter packages. One setup uses 245/40R18 tires, and the other uses 255/35R19 tires, both in radial construction.
That means the tire decision starts with the wheel package rather than with the Base sub-model name. A quick verification of wheel diameter prevents ordering the wrong size, and it is especially important on cars that may have seen wheel changes, tire upgrades, or cosmetic modifications over time.
Choosing the Right Tire
What should I consider when choosing a tire for a 2010 Audi TTS Quattro?
Start with the correct primary size for the wheel package on the car: 245/40R18 for 18-inch wheels or 255/35R19 for 19-inch wheels. From there, compare radial construction details such as tire series, intended use, rim-width specifications, load figures where given, and sidewall presentation.
A street-driven TTS may call for a different tire choice than one set up for specialty use. It also helps to confirm whether the car remains stock, because wheel width, suspension changes, and previous owner modifications can affect which product within the correct size makes the most sense.
What sidewall styles are available for 2010 Audi TTS Quattro tires?
Sidewall style depends on the tire size and product line you choose. In 245/40R18, available sidewall treatments include blackwall, redline, and raised white letter, while the 255/35R19 products offered here are blackwall performance radials.
That gives the 18-inch fitment more visual variety if appearance matters along with size. A traditional blackwall keeps the look understated, while redline or raised white letter options create a more customized presentation, so the sidewall choice should match both the wheel package and the car's intended style.
What brands offer tires for the 2010 Audi TTS Quattro?
Available brands for the 2010 Audi TTS Quattro include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac. Brand availability varies by size, with the 245/40R18 fitment carrying the broadest mix and the 255/35R19 fitment centered on BFGoodrich options.
The practical step is to compare brands within the correct tire size instead of shopping by brand name first. Once size and wheel diameter are confirmed, look at tire series, sidewall style, and intended use so the final choice suits how the car is driven and how the owner wants it to look.
Restoration & Appearance
Which tire should I choose for a period-style 2010 Audi TTS Quattro?
A period-style choice for a 2010 Audi TTS Quattro starts with keeping the correct wheel-diameter fitment in place, either 245/40R18 or 255/35R19. Because this is a modern performance Audi, the tire should still remain a radial, with the visual decision coming from tire series and sidewall treatment rather than vintage construction.
The 245/40R18 fitment offers the most appearance flexibility, including blackwall, redline, and raised white letter options. A buyer aiming for a stock-leaning presentation should verify the wheel setup already on the car and then choose a sidewall style that complements the car without assuming any one treatment is factory-correct.
How does tire construction affect the appearance of a restored 2010 Audi TTS Quattro?
On a 2010 Audi TTS Quattro, construction is less about bias-ply versus radial and more about staying within the modern radial profile the car was designed around. The visible differences come from sidewall treatment, tread style, and the overall visual effect created by the 18-inch or 19-inch wheel-and-tire package.
That means appearance changes can happen even when the tire size remains correct. A blackwall keeps the look contemporary and restrained, while redline or raised white letter on the 245/40R18 fitment creates a more assertive custom impression, so the final choice should reflect the restoration goal rather than fashion alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Audi TTS Quattro?
Yes, modifications can affect tire fitment on a 2010 Audi TTS Quattro even when the tire size looks correct on paper. Aftermarket wheels, suspension changes, altered ride height, and body or brake upgrades can all change how a 245/40R18 or 255/35R19 tire sits within the wheelwell.
A car that remains stock is usually simpler to match, but any changed setup deserves a closer look before replacement. Wheel width, offset, inner clearance, and fender clearance should all be checked so the chosen tire works with the car's actual configuration rather than with its original specification alone.
What should I inspect before driving a 2010 Audi TTS Quattro on new tires?
Before road use, inspect inflation pressure, wheel fastener torque, tread and sidewall condition, and overall clearance at full steering lock. It is also worth checking for rubbing around the fenders, suspension components, and inner wheelhouse once the new tires are mounted.
A short, careful test drive helps confirm that the car tracks properly and that nothing contacts under compression or turning. On a performance-oriented car like the TTS, alignment condition and suspension health also matter, because worn components can affect tire wear and road manners almost immediately.
What should I check before a longer drive in a 2010 Audi TTS Quattro?
Before a longer drive, confirm that the 2010 Audi TTS Quattro is on the correct tire size for its wheel package and that all four tires are in sound condition. Pressure, tread depth, visible damage, and any signs of air loss deserve attention before the car sees sustained highway use.
Longer trips also make it worth checking alignment behavior, vibration, and tire age, especially on a car that may sit between drives. A collector-kept or lightly used example can look fine at a glance yet still need closer inspection for cracking, flat-spotting, or uneven wear.
