2014 Audi A5 Tires

A 2014 Audi A5 uses one of two primary radial tire sizes: 245/40R18 or 255/35R19. Both are modern metric radial fitments, but they are not interchangeable as a simple size choice because each one is built for a different rim diameter.

The practical next step is checking the wheels actually installed on the car. An 18-inch wheel takes the 245/40R18 size, while a 19-inch wheel takes 255/35R19. If the A5 has been modified with aftermarket wheels, confirm the wheel diameter and width before selecting a tire so the new set matches both the wheel and the vehicle’s clearance needs.

The 2014 Audi A5 uses either an 18-inch or a 19-inch rim, depending on which of its two primary tire sizes is on the car. The 245/40R18 size is matched to an 18-inch rim, and the 255/35R19 size is matched to a 19-inch rim.

Rim diameter is the first fitment detail to verify because the tire bead must match the wheel exactly. After that, wheel width still matters, especially when comparing available product specifications within each size. A quick wheel check is especially important on used or modified cars, since a previous owner may have changed the factory-style wheel package.

The covered 2014 Audi A5 Cabriolet follows the same overall fitment pattern as the model core, using either 245/40R18 or 255/35R19 radial tires. That means the fitment is shared at the sub-model level, but it still depends on which wheel diameter the individual car carries.

That distinction matters because the sub-model name alone does not narrow the choice to one size. The safest approach is to confirm the wheel itself and compare the current tire markings before ordering replacements. On a Cabriolet that has had wheel upgrades or seasonal wheel swaps, relying on appearance alone can lead to the wrong tire size.

Start with the correct primary size for the wheel on the car: 245/40R18 for 18-inch rims or 255/35R19 for 19-inch rims. From there, compare radial construction details such as rim-width compatibility, load information when shown, sidewall treatment, and the tire series that best matches how the A5 is driven and presented.

A buyer focused on a straightforward modern look may stay with blackwall options, while someone after a more distinctive appearance may look at redline or raised white letter choices in 245/40R18. Cars used for spirited street driving, occasional specialty use, or visual customization can point toward different product lines even within the same size.

Sidewall choice depends on tire size. In 245/40R18, available styles include blackwall, redline, and RWL, which is raised white letter. In 255/35R19, the available options shown are blackwall, keeping that size focused on a more contemporary performance appearance.

Sidewall style changes the visual character of the car more than the size itself. A blackwall keeps the look restrained and modern, while redline or raised white letter tires make a stronger styling statement on an 18-inch setup. The key is choosing the look after confirming the correct size and wheel diameter rather than treating appearance as the first fitment decision.

Available tire brands for the 2014 Audi A5 include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, depending on size. The broadest mix appears in 245/40R18, while 255/35R19 centers on BFGoodrich options across several g-Force series.

Brand comparison is most useful after the size has been narrowed down. Once the wheel diameter is confirmed, compare each brand’s available series, sidewall styling, rim-width specifications, and any load details shown for that size. That approach keeps the decision grounded in fitment and intended use instead of assuming every brand offers the same kind of tire within both A5 sizes.

A period-style approach for a 2014 Audi A5 usually starts with staying in the correct modern metric radial size for the wheel on the car. The most appearance-focused variety appears in 245/40R18, where blackwall, redline, and raised white letter options create noticeably different visual effects without changing the basic fitment format.

Choosing for appearance still works best when tied to the car’s overall presentation. A restrained build may suit a blackwall tire, while a custom or enthusiast-oriented look may lean toward redline or RWL styling. Exact originality questions should be checked against vehicle-specific historical references if the goal goes beyond period-style presentation and toward a highly precise restoration standard.

On a 2014 Audi A5, construction is straightforward because the primary fitments are radial tires in both available sizes. That means the visual difference is driven less by bias-ply versus radial appearance and more by the tire’s profile, sidewall treatment, and the wheel diameter paired with either 245/40R18 or 255/35R19.

An 18-inch setup in 245/40R18 offers the most visible styling variety because it includes blackwall, redline, and raised white letter choices. The 19-inch 255/35R19 options stay closer to a pure modern performance look. For a restoration-minded owner, the most useful appearance decision is matching the tire’s sidewall style and overall stance to the way the specific A5 is being presented.

Yes. Wheel changes, suspension modifications, ride-height adjustments, and body alterations can all affect tire fitment on a 2014 Audi A5. That matters here because the car already uses two low-profile radial sizes tied to different wheel diameters, so even small changes in wheel setup can alter clearance and compatibility.

A modified A5 should be checked for wheel diameter, width, and clearance at the fender, suspension, and steering points before choosing replacement tires. Cars with aftermarket wheels may no longer match the original size pattern exactly. Verifying the actual setup on the vehicle is more useful than assuming the current tire size is automatically the correct one.

Before driving a 2014 Audi A5 on new tires, inspect the wheel condition, confirm the tire size matches the rim diameter, and make sure the tires are seated and inflated properly. It also helps to check for adequate clearance around the fenders, suspension components, and steering range once the car is back on the ground.

A short follow-up inspection after initial road use is worthwhile, especially on a car with low-profile tires. Recheck pressure, look for any signs of rubbing, and pay attention to vibration that could point to a mounting or wheel issue. On a car with recent wheel or suspension changes, those first miles are the right time to catch a fitment problem early.

Tires on a 2014 Audi A5 should be inspected regularly, with a quick visual check before routine driving and a more thorough inspection at service intervals or before longer trips. Low-profile radial tires benefit from consistent attention because pressure loss, sidewall damage, and uneven wear can affect both ride quality and handling feel.

A good inspection includes looking for cuts, bulges, cracking, unusual shoulder wear, and any evidence of air loss. Cars that sit for long periods should also be checked for age-related condition changes before returning to the road. Pressure should be maintained carefully, since underinflation or overlooked damage is harder to hide on short-sidewall performance tire sizes.
