The 2017 Audi A4 sits in the modern sport-sedan tradition where balanced road manners, clean design, and everyday usability matter just as much as outright performance. In this generation, wheel and tire choice plays a visible role in both the car’s stance and the way it presents itself. This A4 uses radial tire fitments in three sizes: 225/50R17, 245/40R18, and 245/35R19, depending on sub-model and wheel package. Available choices range from straightforward blackwall performance radials to select redline and raised white letter options in 245/40R18. The key is matching the exact size to the car’s trim and wheel diameter before comparing style, series, and road-use priorities.
Which Tire Size Is Right for The 2017 Audi A4
Three tire sizes apply to the 2017 Audi A4, and the correct choice depends on the exact sub-model and wheel diameter. Because these sizes span 17-inch, 18-inch, and 19-inch rims, the first step is confirming which wheels are actually on the car. Once that is settled, the decision shifts to the type of radial tire you want, along with brand, series, and sidewall style where those options exist.
In 225/50R17, the 225 identifies nominal section width in millimeters, the 50 is the aspect ratio, R denotes radial construction, and 17 is the wheel diameter in inches. On the 2017 Audi A4, this is a modern radial fitment suited to 17-inch wheels rather than an older sizing system. Available choices center on blackwall performance-oriented radials from BFGoodrich and Nitto across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, and NT555 G2. This size is the right one to evaluate only after confirming that the car is using the 17-inch wheel setup.
The 245/40R18 size uses a 245-millimeter nominal section width, a 40-series aspect ratio, radial construction, and an 18-inch rim. For the 2017 Audi A4, this size sits in the middle of the available fitment range and appears across multiple sub-models. It also offers the broadest visible product variety, including blackwall options from BFGoodrich, Nitto, and M&H Racemaster, plus Pro-Trac Street Pro III versions in redline and raised white letter form. This is the size to compare when the car already has 18-inch wheels and appearance choice matters alongside basic fitment.
A 245/35R19 tire carries the same nominal 245-millimeter width as the 18-inch option, but with a 35-series profile and a 19-inch rim diameter. On the 2017 Audi A4, it is a modern radial fitment tied to 19-inch wheel setups rather than a substitute for the smaller-wheel configurations. Product selection in this size focuses on blackwall performance radials from BFGoodrich and Nitto, including g-Force and NT555 G2 lines. This size should be considered when the car is already equipped with 19-inch wheels and the goal is to stay with that wheel-and-tire package.
Sub-model fitment matters on the 2017 Audi A4 because tire size changes with the wheel package used on each trim. Premium, Premium Plus, and Prestige do not all start from the same tire choice, so confirming the exact trim and wheel diameter is the best first step.

2017 Audi A4 Premium
The 2017 Audi A4 Premium uses either 225/50R17 or 245/40R18 radial tires, depending on the wheel setup on the car. That makes wheel-diameter confirmation especially important before choosing among blackwall performance tires or comparing series and rim-width compatibility.
The 2017 Audi A4 Premium Plus uses 245/40R18 or 245/35R19 radial tires, so selection depends on whether the car has 18-inch or 19-inch wheels. Once the wheel size is confirmed, the decision becomes one of series, brand, and sidewall presentation within the correct fitment.
The 2017 Audi A4 Prestige also uses either 245/40R18 or 245/35R19 radial tires. Owners should verify the actual wheel package on the car first, then compare the available blackwall, redline, or raised white letter choices where that styling variation is offered.
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.

Common 2017 Audi A4 tire questions usually come down to the correct size for the trim and wheel package, then narrowing the choice by brand, sidewall style, and intended road use. The points below focus on fitment, selection, and basic checks before putting the car back on the road.
Tire Size & Fitment
What tire size fits a 2017 Audi A4?
The 2017 Audi A4 uses three tire sizes: 225/50R17, 245/40R18, and 245/35R19. All three are radial sizes, and the correct one depends on the sub-model and, just as importantly, the wheel diameter actually installed on the car.
The safest starting point is to confirm whether the car has 17-inch, 18-inch, or 19-inch wheels before choosing a tire. A Premium can use 225/50R17 or 245/40R18, while Premium Plus and Prestige use 245/40R18 or 245/35R19, so trim and wheel package should be checked together.
What size rim does a 2017 Audi A4 use?
A 2017 Audi A4 can use 17-inch, 18-inch, or 19-inch rims, depending on the tire size on the car. The three matching tire-and-rim pairings are 225/50R17 on 17-inch rims, 245/40R18 on 18-inch rims, and 245/35R19 on 19-inch rims.
That rim diameter needs to match the tire exactly, so a 19-inch tire is not chosen for an 18-inch wheel, and vice versa. Before comparing tire series or sidewall style, inspect the wheel itself or verify the existing tire size so the replacement search starts with the correct diameter.
Do all 2017 Audi A4 sub-models use the same tire size?
No. The 2017 Audi A4 Premium, Premium Plus, and Prestige do not all use the same tire size. Premium uses 225/50R17 or 245/40R18, while Premium Plus and Prestige use 245/40R18 or 245/35R19.
That difference means trim name alone is not always enough; the actual wheel setup still matters. Two cars with the same model year can require different tires if one has 18-inch wheels and the other has 19-inch wheels, so confirm both the sub-model and the mounted wheel diameter before selecting replacements.
Choosing the Right Tire
What should I consider when choosing a 2017 Audi A4 tire?
Start with the exact size the car uses: 225/50R17, 245/40R18, or 245/35R19. From there, compare radial construction details such as brand, tire series, sidewall style where offered, and wheel-width compatibility rather than treating all tires in the same size as identical.
A driver keeping an 18-inch setup may have the widest range of choices, including blackwall and select redline or raised white letter options in 245/40R18. It also helps to compare load figures when shown, along with the kind of use the car sees, whether that is routine street driving or a more specialized setup.
What sidewall styles are available for 2017 Audi A4 tires?
Blackwall is the most common sidewall style across 2017 Audi A4 tire options. In 245/40R18, there are also Pro-Trac Street Pro III choices with redline and RWL sidewalls, giving that size more visual variety than the 17-inch and 19-inch fitments.
Sidewall style changes the look of the car more than the fitment itself, so the first priority remains the correct size and wheel diameter. Once that is settled, blackwall keeps a cleaner modern presentation, while redline or raised white letter versions create a more customized appearance on cars using the 18-inch package.
What brands offer tires for the 2017 Audi A4?
Tires for the 2017 Audi A4 are available from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, depending on size. BFGoodrich and Nitto appear across multiple fitments, while M&H Racemaster and Pro-Trac show up in the 245/40R18 range.
Brand choice is best considered after size has been narrowed down to the car’s actual wheel package. Once you are in the correct fitment, compare the tire series each brand offers, the sidewall treatment if appearance matters, and any stated wheel-width or load details that affect how the tire suits the intended setup.
Restoration & Appearance
Which tire should I choose for a period-style 2017 Audi A4?
A period-style approach on a 2017 Audi A4 still starts with the correct modern radial size for the car’s trim and wheel package. For most owners, that means choosing among 225/50R17, 245/40R18, or 245/35R19 and then selecting a tire whose sidewall presentation matches the look they want.
Blackwall tires keep the most understated appearance across all three sizes, while 245/40R18 also opens the door to redline or raised white letter styling for a more customized presentation. If originality matters beyond general appearance, compare the tire choice against photos, window-sticker records, or marque-specific references for the car’s actual configuration.
How does tire construction affect the appearance of a restored 2017 Audi A4?
Tire construction is straightforward on the 2017 Audi A4 because the primary fitments are radial across all three sizes. That means the appearance difference comes less from bias-ply versus radial construction and more from the size, sidewall height, wheel diameter, and sidewall styling chosen.
A 17-inch setup with 225/50R17 presents differently from a 19-inch setup with 245/35R19 even though both are correct A4 fitments. Owners aiming for a clean restoration-oriented look should pay close attention to wheel size and sidewall treatment first, since those choices shape the visual character of the car more than construction type here.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Audi A4?
Yes. Modifications can affect tire fitment on a 2017 Audi A4 even when the tire size itself is one of the correct factory-style fitments. Aftermarket wheels, altered wheel widths, suspension changes, or body modifications can all change how a 225/50R17, 245/40R18, or 245/35R19 tire sits on the car.
A car with non-stock wheels should have wheel diameter and width confirmed before replacement tires are chosen. Clearance at the fender, inner wheelhouse, and during full steering travel also deserves a quick check, especially when moving between wheel packages or when the car has been lowered or otherwise changed from stock ride height.
What should I inspect before driving a 2017 Audi A4 on new tires?
Before driving on new tires, inspect basic installation and condition points: correct size, proper inflation, secure wheel attachment, and even seating around the rim. It also helps to make sure there is no rubbing at the front during full lock or at the rear under normal suspension movement.
A brief follow-up inspection after the first miles is worthwhile, especially on a car with multiple possible wheel packages like the 2017 Audi A4. Recheck pressure, look for unusual wear or contact marks, and confirm that the chosen tire matches the wheel setup the car is actually running rather than only the trim designation.
How often should tires on a 2017 Audi A4 be inspected?
Tires on a 2017 Audi A4 should be inspected regularly, not just when tread looks low. Pressure loss, sidewall cuts, bulges, cracking, and irregular wear can develop before the tire looks obviously worn, and those issues matter whether the car is used daily or only driven occasionally.
A quick visual check before longer drives is a smart habit, especially if the car sits for stretches between outings. Cars with 18-inch or 19-inch packages also benefit from periodic wheel-and-tire checks for curb damage and alignment-related wear, since catching a problem early is easier than sorting out a ruined tire later.
