The 2013 Audi A3 Quattro sits in the sweet spot between compact luxury hatchback practicality and the surefooted all-weather character that made Quattro models so appealing to daily drivers and enthusiasts alike. It is modern enough to use contemporary low-profile radial fitments, but specific enough that wheel diameter matters before any tire decision is made. This model uses either 225/45R17 or 225/40R18 radial tires, both tied to distinct 17-inch or 18-inch wheel setups. Available choices include blackwall performance-oriented tires, along with raised white letter and redline options in 225/45R17. The right choice starts with confirming the wheels actually on the car, then balancing appearance, road use, and tire-series preference.
Which Tire Size Is Right for The 2013 Audi A3 Quattro
The 2013 Audi A3 Quattro uses two primary tire sizes, and the correct one depends first on wheel diameter. Both fitments are radial, but one is built around a 17-inch wheel and the other around an 18-inch wheel. Before comparing brands or sidewall styles, confirm which wheel package is on the car so the tire size matches the actual rim diameter.
225/40R18 is a metric radial size with a 225-millimeter section width, a 40-series aspect ratio, and fitment for an 18-inch rim. On the 2013 Audi A3 Quattro, this size supports a lower-profile look and is offered in modern radial performance-oriented tire lines from BFGoodrich and Nitto, all in blackwall form. Tire series in this size include g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This is the size to evaluate when the car already wears 18-inch wheels and the goal is to stay with that wheel-and-tire package.
225/45R17 is a metric radial size that uses the same 225-millimeter nominal width but a taller 45-series profile on a 17-inch rim. For the 2013 Audi A3 Quattro, this size opens up a broader mix of choices, including blackwall performance tires plus Pro-Trac Street Pro III options with raised white letter or redline sidewall treatment. Available series include g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, NT555 G2, and Street Pro III. It is the right size to consider when the car is equipped with 17-inch wheels and you want either a standard modern appearance or a more distinctive sidewall style.
Fitment is straightforward here because the covered sub-model uses the same two radial tire sizes already associated with the 2013 Audi A3 Quattro. The important step is not choosing between trims, but confirming whether the car is on 17-inch or 18-inch wheels before selecting a tire.

Tire Size & Fitment
What tire size fits a 2013 Audi A3 Quattro?
The 2013 Audi A3 Quattro uses two primary tire sizes: 225/45R17 and 225/40R18. Both are radial fitments, and each size corresponds to a different wheel diameter, so the correct choice depends on whether the car has 17-inch or 18-inch rims.
The practical next step is to check the wheels actually on the car, especially if it has changed hands or has been modified. A3 Quattro models can wear either size, but the tire must match the installed rim diameter before comparing brands, sidewall styles, or tire series.
What size rim does a 2013 Audi A3 Quattro use?
A 2013 Audi A3 Quattro uses either a 17-inch or 18-inch rim, depending on which tire size is on the car. The 225/45R17 fitment uses a 17-inch wheel, while the 225/40R18 fitment uses an 18-inch wheel.
Checking the rim diameter matters more than anything else at the start of the buying process. The two tire sizes are close in overall dimensions, but they are not intended for the same wheel, so reading the current tire sidewall or measuring the wheel is the safest way to confirm fitment.
Do all 2013 Audi A3 Quattro sub-models use the same tire size?
The covered 2013 Audi A3 Quattro Base sub-model can use both primary sizes associated with this model: 225/45R17 and 225/40R18. That means sub-model identification alone does not narrow the choice to one tire size without also confirming the wheel package on the car.
For an owner, that makes wheel verification the real fitment step. A Base model on 17-inch wheels needs the 17-inch tire size, while a Base model on 18-inch wheels needs the 18-inch fitment, and tire selection can move on to series, sidewall style, and road-use preference from there.
Choosing the Right Tire
What should I consider when choosing a 225/45R17 or 225/40R18 tire for a 2013 Audi A3 Quattro?
Start with the correct size for the wheel diameter on the car: 225/45R17 for 17-inch rims or 225/40R18 for 18-inch rims. From there, compare radial tire series, sidewall presentation, rim-width suitability where stated, and any product details such as load figures or tire weight.
The best comparison depends on how the A3 Quattro is used. A buyer focused on a straightforward modern look may stay with blackwall options, while someone wanting a more distinctive appearance may look closely at the 225/45R17 choices that include raised white letter or redline sidewalls.
What sidewall styles are available for 2013 Audi A3 Quattro tires?
Blackwall is available in both 225/45R17 and 225/40R18 for the 2013 Audi A3 Quattro. In 225/45R17, there are also Pro-Trac Street Pro III options with RWL sidewalls and with a redline sidewall treatment.
Sidewall style changes the car's visual character more than the size itself, so it is worth deciding whether the goal is a standard contemporary look or something with more visual emphasis. The sidewall choice still needs to be made within the correct tire size for the wheel diameter already on the car.
What brands offer tires for the 2013 Audi A3 Quattro?
Tires for the 2013 Audi A3 Quattro are available from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich and Nitto cover both primary sizes with blackwall radial options, while Pro-Trac appears in 225/45R17 with Street Pro III choices that include distinctive sidewall treatments.
Brand comparison should come after confirming the proper size and wheel diameter. Once that is settled, the useful differences are series character, sidewall appearance, rim-width compatibility where stated, and the overall presentation you want from the car rather than assuming one brand is automatically the right answer.
Restoration & Appearance
Which tire should I choose for a period-style 2013 Audi A3 Quattro?
A period-style choice for a 2013 Audi A3 Quattro still starts with the correct modern radial size for the wheel on the car, either 225/45R17 or 225/40R18. Among the available options, 225/45R17 gives the widest appearance range because it includes blackwall, raised white letter, and redline sidewall treatments.
That makes 225/45R17 the more flexible fitment if visual character matters as much as size. The final decision should reflect how the car is being presented, since a clean blackwall look feels more contemporary while RWL or redline sidewalls create a stronger custom or enthusiast-oriented appearance.
How does tire construction affect the appearance of a restored 2013 Audi A3 Quattro?
On a 2013 Audi A3 Quattro, the available primary fitments are radial tires, so construction choice is less about switching between vintage tire types and more about selecting the right modern presentation. Appearance differences here come mainly from profile, wheel diameter, tire series, and sidewall style rather than bias-ply versus radial decisions.
That puts more emphasis on matching the tire to the car's intended look. An 18-inch setup with 225/40R18 reads as a lower-profile modern fitment, while 225/45R17 offers a slightly fuller sidewall and more visible style variation if the goal is a more individualized restoration-oriented presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Audi A3 Quattro?
Yes, modifications can change how a tire works on a 2013 Audi A3 Quattro even when the size looks close to stock. Aftermarket wheels, different wheel widths, suspension changes, or body and fender alterations can all affect clearance, steering range, and the space available for either 225/45R17 or 225/40R18.
That is why the installed setup should be checked before choosing a replacement tire. A modified car may still use one of the standard sizes, but wheel diameter, wheel width, and available clearance should be confirmed so the new tire matches the actual configuration rather than only the original model fitment.
What should I inspect before driving a 2013 Audi A3 Quattro on new tires?
Before putting a 2013 Audi A3 Quattro back into regular use on new tires, inspect the wheels for damage, confirm the tire size matches the installed rim diameter, and check that there is no interference at the fenders or suspension through the steering range. Tire pressure should also be set correctly for the application.
It also helps to look over the rest of the car's contact-point hardware. Worn suspension parts, alignment issues, or uneven wheel mounting surfaces can shorten tire life quickly, so a careful once-over before road use gives the new tires a better chance to wear evenly and behave as intended.
How often should tires on a 2013 Audi A3 Quattro be inspected?
Tires on a 2013 Audi A3 Quattro should be inspected regularly, not only when tread looks low. A quick visual check for cuts, bulges, irregular wear, and pressure loss is smart before longer trips, and a closer inspection at routine service intervals helps catch issues that may not be obvious day to day.
That habit matters even more on a car that is driven inconsistently or stored for stretches at a time. Low-use vehicles can still develop age-related concerns, so checking sidewalls, tread condition, and air retention periodically helps the correct 225/45R17 or 225/40R18 tires stay road-ready.
