The 2013 Audi A4 Quattro sits in the modern sport-sedan sweet spot, blending understated Audi styling with all-wheel-drive confidence and the crisp road manners that made the A4 a benchmark in its class. For this exact model year, tire choice starts with identifying the correct factory-size range, because the A4 Quattro uses four different metric radial fitments depending on configuration. Those sizes span 17-inch, 18-inch, and 19-inch wheel setups, with available choices including blackwall performance tires as well as redline and raised white letter styles in certain sizes. The right pick depends on matching the car's wheel package, desired appearance, and intended street use before anything else.
Which Tire Size Is Right for The 2013 Audi A4 Quattro
The 2013 Audi A4 Quattro uses four primary tire sizes, and they do not all share the same wheel diameter. Fitment varies by sub-model and wheel package, so the first step is confirming whether the car has 17-inch, 18-inch, or 19-inch wheels and then identifying the exact sub-model. Once that is settled, the decision shifts to tire series, brand, sidewall style, and intended driving use within the correct radial size.
255/35R19 is a metric radial size in which 255 is the section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 19 is the wheel diameter in inches. On the 2013 Audi A4 Quattro, this size belongs to the 19 Inch Option setup and represents the largest wheel package used here. Available choices center on BFGoodrich blackwall performance-oriented tire series, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. This size is the one to evaluate when the car is already equipped with 19-inch wheels and you want to keep that low-profile, modern performance presentation.
225/50R17 is a metric radial size that uses a 225-millimeter section width, a 50-series profile, and a 17-inch rim. On the 2013 Audi A4 Quattro, it is one of the 17-inch fitments used on the Base sub-model, so it should not be assumed to apply to every A4 Quattro without checking the wheel setup first. Product choices include blackwall radial tires from BFGoodrich and Nitto across several performance-oriented series. This size makes sense when the car retains its 17-inch wheel package and the goal is choosing among compatible radial options rather than moving to a different wheel diameter.
245/40R18 is a metric radial tire size with a 245-millimeter section width, a 40-series profile, and an 18-inch rim diameter. For the 2013 Audi A4 Quattro, this is one of the Base sub-model fitments and it brings a wider, lower-profile 18-inch setup than the 17-inch sizes. Choices are broader here, with blackwall options from BFGoodrich, Nitto, and M&H Racemaster, plus Pro-Trac Street Pro III offerings in redline and raised white letter form. This is the size to focus on when the car already wears 18-inch wheels and the buyer wants to compare appearance-driven and performance-minded radial choices.
245/45R17 is a metric radial size that combines a 245-millimeter section width with a 45-series profile on a 17-inch wheel. On the 2013 Audi A4 Quattro, it is another Base sub-model fitment, which means wheel diameter alone does not fully settle the choice because more than one 17-inch size appears on this model. Available products include blackwall tires from BFGoodrich, Nitto, and M&H Racemaster, along with Pro-Trac Street Pro III versions in redline and raised white letter styling. This size deserves a careful check against the car's existing wheel and tire setup before selecting among the available radial options.
Sub-model fitment matters on the 2013 Audi A4 Quattro because tire size changes with the wheel package. The 19 Inch Option uses its own size, while the Base sub-model can use multiple radial sizes, so confirming the exact setup is the key first step.

2013 Audi A4 Quattro (19 Inch Option)
The 2013 Audi A4 Quattro (19 Inch Option) uses a dedicated 19-inch radial fitment rather than sharing the Base model's smaller wheel sizes. Tire selection here is mainly about staying with the correct 19-inch setup and comparing available blackwall performance series within that size.
The 2013 Audi A4 Quattro Base uses more than one radial tire size, covering both 17-inch and 18-inch wheel packages. That makes wheel confirmation especially important before choosing a tire, since the right option depends on the car's actual rim diameter and existing setup.
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 2013 Audi A4 Quattro?
The 2013 Audi A4 Quattro uses four primary radial tire sizes: 225/50R17, 245/45R17, 245/40R18, and 255/35R19. The Base sub-model uses 225/50R17, 245/40R18, and 245/45R17, while the 19 Inch Option uses 255/35R19.
The practical step is confirming the exact wheel package already on the car before choosing a tire. This model uses more than one rim diameter, and even the 17-inch setup appears in two different sizes, so checking the sidewall markings on the current tires and the wheel diameter is the safest way to match the correct fitment.
What size rim does a 2013 Audi A4 Quattro use?
A 2013 Audi A4 Quattro can use 17-inch, 18-inch, or 19-inch rims depending on configuration. The tire sizes tied to those wheel diameters are 225/50R17 and 245/45R17 for 17-inch wheels, 245/40R18 for 18-inch wheels, and 255/35R19 for the 19 Inch Option.
That range means rim diameter has to be verified before comparing tires. A tire designed for a 17-inch wheel cannot be mounted on an 18-inch or 19-inch rim, and the two 17-inch choices still need to be matched to the car's existing setup. Checking the current wheel and tire markings prevents ordering the right size for the wrong wheel.
Why does the 2013 Audi A4 Quattro have more than one tire size?
The 2013 Audi A4 Quattro has more than one tire size because it was offered with different wheel packages. The Base model alone uses multiple radial sizes, and the separate 19 Inch Option adds a distinct 255/35R19 fitment on a larger wheel diameter.
That variation means tire selection starts with the car in front of you, not just the model name. A4 Quattro owners should confirm the sub-model and then verify the actual wheel diameter and current tire markings, especially on cars that may have had wheel changes, seasonal tire swaps, or previous aftermarket replacements.
Choosing the Right Tire
What should I consider when choosing a 2013 Audi A4 Quattro tire?
Start with the correct size for the car's wheel package, since the 2013 Audi A4 Quattro uses 225/50R17, 245/45R17, 245/40R18, or 255/35R19 depending on setup. From there, compare radial construction details, brand, tire series, sidewall style, and any published rim-width or load information that applies to that exact size.
The best comparison is between tires in the same correct size, not across different wheel diameters. An owner using the car mainly for street driving may focus on series and appearance, while someone with a more specialized use may compare product attributes more closely. Matching the tire to the existing wheels remains the first requirement.
What sidewall styles are available for 2013 Audi A4 Quattro tires?
Blackwall is available across all four 2013 Audi A4 Quattro tire sizes in the current selection. For 245/40R18 and 245/45R17, additional sidewall choices include redline and RWL, giving those two sizes more visual variety than the 17-inch 225/50R17 and 19-inch 255/35R19 fitments.
That makes sidewall style a real selection factor once the correct size is confirmed. A blackwall keeps the presentation understated and modern, while redline or raised white letter options create a more pronounced visual statement. Appearance should be chosen after fitment is settled, since sidewall treatment does not override the need for the proper size and wheel match.
What brands offer tires for the 2013 Audi A4 Quattro?
Tires for the 2013 Audi A4 Quattro are available here from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, depending on size. BFGoodrich appears across all four fitments, while Nitto, M&H Racemaster, and Pro-Trac are available in selected 17-inch and 18-inch sizes.
Brand choice should be compared within the exact tire size the car needs. Some sizes offer only blackwall performance-oriented selections, while others add redline, raised white letter, or drag-radial style options. Looking at brand alongside tire series, sidewall treatment, and wheel compatibility gives a more useful comparison than choosing by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2013 Audi A4 Quattro?
A period-style choice for a 2013 Audi A4 Quattro starts with keeping the correct factory-era wheel diameter and tire size already used on the car, whether that is 17, 18, or 19 inches. From there, the most restrained look usually comes from blackwall radial tires in the proper size and profile family.
Because this is a modern Audi rather than an earlier collector-era car, appearance decisions are usually more about preserving the car's original visual balance than recreating an antique tire style. Owners who care about a faithful presentation should avoid changing wheel diameter casually and should compare sidewall treatments with the car's overall trim and stance in mind.
How does tire construction affect the appearance of a restored 2013 Audi A4 Quattro?
Construction is straightforward on the 2013 Audi A4 Quattro because the primary fitments are radial tires across all listed sizes. That means the visual difference usually comes less from bias-ply versus radial appearance and more from the tire's profile, wheel diameter, and whether the sidewall is blackwall, redline, or raised white letter.
A car kept close to its original road-going character generally benefits from staying with the proper radial size and wheel package. Changing to a different diameter or a much different sidewall treatment can alter the look more noticeably than many owners expect, especially on a sedan whose proportions rely on a balanced wheel-to-tire relationship.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Audi A4 Quattro?
Yes. Modifications such as aftermarket wheels, changes in wheel width, offset differences, suspension lowering, or body changes can all affect tire fitment on a 2013 Audi A4 Quattro. That matters even more here because the car already uses several factory tire sizes across 17-inch, 18-inch, and 19-inch wheel packages.
A modified car should be checked for more than just wheel diameter. Tire clearance at full steering lock, fender space, suspension travel, and the actual wheel width all deserve attention before choosing a replacement. Even when the sidewall shows a familiar size, a changed wheel or ride height can alter what works comfortably on the car.
What should I inspect before driving a 2013 Audi A4 Quattro on new tires?
Before driving a 2013 Audi A4 Quattro on new tires, confirm that all four tires are the correct size for the wheel package, mounted on the proper rim diameter, and inflated appropriately for the application. It is also wise to inspect the wheels themselves for damage and make sure the tires clear the suspension and bodywork.
A short initial check after installation can prevent bigger issues later. Watch for rubbing during turning, vibration at speed, uneven seating, or unexpected air loss, and recheck pressure once the tires have settled. On a car that has seen previous wheel changes, verifying lug hardware and overall wheel condition is just as important as the tire selection.
How often should tires on a 2013 Audi A4 Quattro be inspected?
Tires on a 2013 Audi A4 Quattro should be inspected regularly, not just when tread looks low. Frequent checks for pressure loss, uneven wear, cuts, bulges, and sidewall damage are especially important on lower-profile sizes such as 245/40R18 and 255/35R19, where road impacts can be harder on both tire and wheel.
A good routine is to inspect the tires before longer drives and any time the car feels different on the road. Cars that sit for stretches still need attention, since age, storage conditions, and gradual air loss can affect tire condition even when mileage stays low. Consistent inspection helps catch problems before they become a roadside issue.
