The 2014 Audi A4 sits in the era when sport sedans were expected to balance everyday refinement with sharp road manners, and tire choice plays directly into that character. Buyers looking at this exact A4 are usually sorting out trim-specific wheel packages as much as tire replacement itself. This model uses radial fitments in 245/45R17, 245/40R18, or 255/35R19, depending on sub-model and wheel option. Available choices range from blackwall performance-oriented tires to redline and raised white letter options in some sizes. The real key is matching the tire to the car’s actual wheel diameter, intended appearance, and how the car will be driven.
Which Tire Size Is Right for The 2014 Audi A4
Three tire sizes apply to the 2014 Audi A4, and they do not all fit every version of the car. The first step is confirming the exact sub-model and wheel diameter, since this A4 can use 17-inch, 18-inch, or 19-inch rims depending on trim and option package. Once that is established, the decision shifts to tire series, sidewall style, and how closely the tire matches the car’s intended use.
The 245/40R18 size uses modern metric radial sizing: 245 is 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 2014 Audi A4, this is one of the core fitments and suits cars equipped with 18-inch wheels. Product choices in this size include blackwall, redline, and raised white letter sidewall styles, along with series from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac. It is the right size to evaluate when the car already wears 18-inch wheels and the goal is to balance fitment with appearance and use.
The 245/45R17 size follows the same metric radial pattern, with a 245-millimeter nominal section width, a 45-series profile, radial construction, and a 17-inch rim diameter. For the 2014 Audi A4, this size belongs to specific configurations that use 17-inch wheels rather than the larger 18-inch or 19-inch setups. Available tires include blackwall, redline, and raised white letter options across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, Street Pro III, Drag Radial, and g-Force Phenom T/A. This size should be chosen only after confirming the car is actually on the 17-inch wheel package.
Fit(s): Premium Plus and Prestige (19 Inch Option)
Construction: Radial|Rim: 19 in
The 255/35R19 size is a modern metric radial with a 255-millimeter nominal section width, a 35-series profile, radial construction, and a 19-inch rim diameter. On the 2014 Audi A4, this fitment is tied to certain Premium Plus and Prestige 19 Inch Option configurations using the largest wheel package of the group. Product selection in this size centers on BFGoodrich blackwall tires across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. It is the correct path only when the car has 19-inch wheels and enough wheel-width compatibility for this size range.
Sub-model fitment matters on the 2014 Audi A4 because tire size changes with trim level and wheel package. Before choosing a tire, confirm whether the car is a Premium, Premium Plus, Prestige, or Prestige with the 19 Inch Option, then match that to the actual rim diameter on the car.

2014 Audi A4 Premium
The 2014 Audi A4 Premium can use either a 245/45R17 or 245/40R18 radial, depending on which wheel package is on the car. That makes wheel-diameter confirmation essential before comparing brands, sidewall styles, or performance-oriented tire series.
The 2014 Audi A4 Premium Plus uses either 245/40R18 or 255/35R19 radial fitment, so this trim does not have a single universal replacement size. Tire selection starts with confirming whether the car is on 18-inch or 19-inch wheels, then narrowing choices by tire series and intended road use.
The 2014 Audi A4 Prestige uses 245/40R18 radial tires in its standard covered fitment. That keeps the size decision straightforward, allowing attention to shift toward blackwall, redline, or raised white letter presentation and the character of the available tire series.
The 2014 Audi A4 Prestige (19 Inch Option) uses 255/35R19 radial tires with the larger wheel setup. That makes product selection more focused, since the available choices stay within blackwall performance-style tires on 19-inch rims.
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.

These FAQs focus on the tire sizes used on the 2014 Audi A4, how trim and wheel packages affect fitment, and what to compare when choosing among available radial tires for replacement or specialty use.
Tire Size & Fitment
What tire size fits a 2014 Audi A4?
A 2014 Audi A4 can use 245/45R17, 245/40R18, or 255/35R19, depending on sub-model and wheel package. All three are radial fitments, but they are not interchangeable as a single universal size across the entire A4 lineup.
The practical starting point is the wheel already on the car. Premium models can use 17-inch or 18-inch fitment, Premium Plus can use 18-inch or 19-inch fitment, Prestige uses 18-inch fitment, and Prestige with the 19 Inch Option uses 19-inch fitment. Tire selection should follow the actual wheel diameter and trim-specific setup.
What size rim does a 2014 Audi A4 use?
The 2014 Audi A4 uses 17-inch, 18-inch, or 19-inch rims, depending on sub-model and wheel option. Those rim diameters correspond to 245/45R17, 245/40R18, and 255/35R19 tire sizes respectively.
Checking the actual wheel diameter is more important than assuming all A4 trims use the same setup. A Premium may be on 17-inch or 18-inch wheels, while some Premium Plus and Prestige cars can be on larger wheels. Before ordering tires, verify the wheel size stamped on the rim or confirm the existing tire size on the car.
Do all 2014 Audi A4 sub-models use the same tire size?
No, the 2014 Audi A4 does not use one tire size across all covered sub-models. Premium, Premium Plus, Prestige, and Prestige with the 19 Inch Option can have different tire sizes because the wheel packages vary.
That means trim level alone is helpful, but the actual wheel on the car still needs to be confirmed. A Premium can be on 17-inch or 18-inch fitment, while a Premium Plus may be on 18-inch or 19-inch fitment. Matching the tire to the real wheel diameter avoids choosing a size that belongs to a different A4 configuration.
Choosing the Right Tire
What should I consider when choosing a tire for a 2014 Audi A4?
Start with the correct tire size for the car’s trim and wheel package: 245/45R17, 245/40R18, or 255/35R19. From there, compare radial tire series, sidewall style, rim-width compatibility, load figures where given, and whether the tire is meant for street use or a more specialized purpose.
A blackwall performance-style tire may suit a stock sport sedan look, while redline or raised white letter options create a more customized presentation in some sizes. It also helps to think about how the A4 will be used. A regularly driven street car and a specialty build can point toward very different tire choices, even within the same size.
What sidewall styles are available for 2014 Audi A4 tires?
Sidewall style depends on the tire size. Blackwall options are available in all three A4 sizes, while 245/40R18 and 245/45R17 also offer redline and RWL, or raised white letter, choices through the Street Pro III line.
That gives the 17-inch and 18-inch fitments more flexibility if appearance matters as much as replacement sizing. Buyers who want a cleaner late-model look may stay with blackwalls, while redline or raised white letter styles push the car toward a more customized visual statement. The important step is keeping the correct tire size tied to the wheel diameter already on the car.
What brands offer tires for the 2014 Audi A4?
Available 2014 Audi A4 tire brands include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, depending on size. The broadest brand spread appears in 245/40R18 and 245/45R17, while 255/35R19 stays within BFGoodrich offerings in the current selection.
Brand comparison is most useful after the correct size is confirmed. Some options focus on street-oriented performance series, while others lean into specialty categories such as drag radial use or distinctive sidewall presentation. Rather than choosing by brand name alone, compare the size, intended use, sidewall style, and wheel-width compatibility that best matches the A4’s current setup.
Restoration & Appearance
Which tire should I choose for a period-style 2014 Audi A4?
A period-style approach on a 2014 Audi A4 starts with keeping the correct original-type wheel diameter for the specific trim and then selecting a radial tire that suits the look you want. Blackwall tires are the most conventional visual fit across all three A4 sizes.
Some 17-inch and 18-inch options also add redline or raised white letter styling, which creates a more customized appearance rather than a restrained factory-inspired one. Buyers aiming for an authentic showroom-era presentation usually focus first on correct size and wheel package, then choose a sidewall style that does not visually overpower the car’s original design language.
How does tire construction affect the appearance of a restored 2014 Audi A4?
On the 2014 Audi A4, primary fitment is already radial, so construction choice is less about bias-ply versus radial appearance and more about the tire’s overall presentation. The visible differences come more from sidewall styling, tread character, and wheel-to-tire proportion within the correct 17-inch, 18-inch, or 19-inch setup.
A blackwall tire generally keeps the car closest to the understated look associated with a modern German sport sedan. Redline and raised white letter versions in some sizes change that character noticeably. For an appearance-driven build, keeping the correct size and profile for the wheel package usually matters more than pursuing a dramatic sidewall treatment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Audi A4?
Yes, modifications can affect tire fitment on a 2014 Audi A4 even when the nominal tire size seems correct. Aftermarket wheels, changes in wheel width or offset, suspension lowering, and brake upgrades can all influence how a 245/45R17, 245/40R18, or 255/35R19 tire sits on the car.
A modified A4 should be checked for fender clearance, inner suspension clearance, and steering clearance before settling on a replacement tire. The same size that works on a stock wheel may behave differently on an aftermarket wheel. That is especially important with the 19-inch fitment, where wheel-width compatibility deserves close attention.
What should I inspect before driving a 2014 Audi A4 on new tires?
Before driving a 2014 Audi A4 on new tires, inspect wheel condition, verify the tires match the car’s actual wheel diameter, and confirm there is no interference at full steering lock or through suspension movement. Tire pressure should also be checked before the first serious road use.
It is also smart to look over alignment-related wear items and the condition of suspension components, especially on a used sport sedan. Uneven wear, damaged wheels, or tired bushings can shorten tire life quickly. A careful inspection helps the new tires wear evenly and keeps the A4’s handling consistent with the wheel package installed.
How often should tires on a 2014 Audi A4 be inspected?
Tires on a 2014 Audi A4 should be inspected regularly, not just when replacement is due. Frequent checks for pressure loss, uneven tread wear, cuts, bulges, and sidewall damage are especially worthwhile on a car that sees mixed daily driving, seasonal use, or long parked periods.
A monthly visual inspection is a sensible habit, with extra attention before highway trips or after pothole impacts. Cars running low-profile 18-inch or 19-inch fitments can be more sensitive to wheel damage and alignment issues. Catching problems early helps preserve ride quality, handling, and the service life of the correct A4 tire size.
