2014 Audi A4 Quattro Tires

The 2014 Audi A4 Quattro uses three primary tire sizes: 245/45R17, 245/40R18, and 255/35R19. All are radial sizes, and the correct one depends on the trim level and wheel package rather than a one-size-fits-all fitment across the full model range.

The most important step is confirming the car's actual wheel diameter before selecting a tire. A Premium model may be on 17-inch or 18-inch wheels, while certain Premium Plus and Prestige cars use either 18-inch wheels or the 19 Inch Option, so the mounted wheel setup should be checked on the vehicle itself before comparing tire choices.

A 2014 Audi A4 Quattro can use 17-inch, 18-inch, or 19-inch rims, depending on the sub-model and wheel package. The 245/45R17 size uses a 17-inch rim, the 245/40R18 size uses an 18-inch rim, and the 255/35R19 size uses a 19-inch rim.

That rim diameter needs to match the tire size exactly, so it is not enough to identify the car only by year and model. If the car has been changed from its original wheel package, or if seasonal or aftermarket wheels are installed, confirm the wheel diameter and width on the vehicle before narrowing the tire search.

The 2014 Audi A4 Quattro has more than one tire size because trim level and wheel-package choices change the wheel diameter and tire profile. Premium models can use either 245/45R17 or 245/40R18, while certain Premium Plus and Prestige versions with the 19 Inch Option use 255/35R19.

That means the right tire is tied to the car's exact configuration rather than the model name alone. It is worth checking the sub-model, the current wheel size, and whether the car still has its original wheel-and-tire setup, especially if it has been modified or purchased used with a different set of wheels.

Start by confirming that 245/40R18 is the size used on the car, since this fitment applies to several 2014 Audi A4 Quattro trims but not all of them. Once the size is confirmed, compare tire construction, intended use, sidewall style, rim-width compatibility, and any load information that matters for the way the car is driven.

This size includes blackwall choices from BFGoodrich, Nitto, and M&H Racemaster, plus Pro-Trac Street Pro III options in redline and RWL. A street-driven sedan, an appearance-focused build, and a specialized use case such as drag-oriented driving can point to different tire series, so the best match depends on how the car is actually used.

Sidewall styling for the 2014 Audi A4 Quattro includes blackwall, redline, and RWL options, depending on tire size. The broadest appearance choice appears in the 245/40R18 and 245/45R17 sizes, where Pro-Trac Street Pro III tires are offered with redline and raised white letter sidewalls alongside blackwall alternatives.

Sidewall style is mostly an appearance decision once the correct size and rim diameter are established. Blackwall keeps a more contemporary look, while redline or RWL can change the visual character of the car noticeably, so it helps to decide whether the goal is a clean modern presentation or a more customized enthusiast look.

Tires for the 2014 Audi A4 Quattro are available from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, depending on size. BFGoodrich appears across all three primary sizes, while Nitto, M&H Racemaster, and Pro-Trac are present in the 17-inch and 18-inch fitments.

Brand alone should not be the only deciding factor. It makes more sense to compare the correct size first, then look at series differences, sidewall treatment, rim-width suitability, and whether the tire is aimed at general street use, all-season service, a more aggressive performance role, or a specialized drag-oriented application.

A period-style approach for a 2014 Audi A4 Quattro usually starts with keeping the wheel diameter and tire size that match the car's trim or option package. Since this model uses modern metric radial sizes, a period-appropriate look is more about preserving the overall stance and profile than choosing a vintage-style bias-ply presentation.

For a restrained factory-era appearance, blackwall options generally keep the visual character closest to a contemporary luxury sport sedan. Redline and RWL versions in the 17-inch and 18-inch sizes offer a more customized look, so the right choice depends on whether the goal is subtle authenticity to the era or a more personalized finish.

On a 2014 Audi A4 Quattro, tire construction does not create a bias-ply-versus-radial appearance choice because the primary fitments are all radial. The visual differences come more from size, wheel diameter, sidewall profile, and sidewall treatment than from switching between fundamentally different tire constructions.

A 17-inch setup with a 245/45R17 tire presents differently than an 18-inch 245/40R18 or a 19-inch 255/35R19 package, even though all are radials. Keeping the correct size for the car's trim and wheel package usually matters more to the finished look than chasing a different construction style that was not part of this model's fitment pattern.

Yes, modifications can affect tire fitment on a 2014 Audi A4 Quattro. Changes such as aftermarket wheels, altered wheel width, different offset, lowered suspension, or body and fender modifications can all change how a 245/45R17, 245/40R18, or 255/35R19 tire sits and clears the car.

A car that no longer has its original wheel setup should be checked carefully before replacing tires by size alone. Measure the actual wheel diameter and width, inspect clearance at full steering lock and through suspension movement, and confirm that the chosen tire's dimensions and load capability still make sense for the vehicle's present configuration.

Before driving a 2014 Audi A4 Quattro on new tires, inspect wheel condition, valve stems, mounting direction where applicable, inflation pressure, and overall clearance around the suspension and fenders. It also helps to confirm that all four tires match the intended size and that the wheel diameter corresponds to the installed tire.

The first short drive should be used to watch for rubbing, vibration, air loss, or any steering behavior that feels unusual. A Quattro-equipped sedan benefits from consistent tire sizing across the set, so it is smart to verify the installed tires carefully and address alignment or wheel-condition issues before putting the car into regular service.

Tires on a 2014 Audi A4 Quattro should be inspected regularly, not only at replacement time. A quick check for pressure loss, uneven wear, cuts, bulges, embedded debris, and sidewall damage is worthwhile throughout the driving season, especially on lower-profile 18-inch and 19-inch fitments that can be more sensitive to road impacts.

Cars that are driven less often still need inspection because age, storage conditions, and long periods of inactivity can affect tire condition. Looking over the tires before longer drives, after pothole strikes, or whenever the car develops vibration or pull can catch problems early and help preserve both ride quality and fitment safety.
