2013 Audi A5 Tires

The 2013 Audi A5 uses two primary tire sizes: 245/40R18 and 255/35R19. Both are radial fitments, and each one is tied to a different wheel diameter, so the correct size depends on whether the car has 18-inch or 19-inch rims.

That makes wheel confirmation the first step before comparing brands or tire series. Checking the size molded into the current tire sidewall and verifying the actual wheel diameter on the car helps avoid choosing a tire that matches the model but not the wheel setup currently installed.

A 2013 Audi A5 uses either an 18-inch or 19-inch rim, depending on which tire fitment is on the car. The 245/40R18 size pairs with an 18-inch wheel, while the 255/35R19 size pairs with a 19-inch wheel.

Rim diameter is the non-negotiable part of the fitment decision because an 18-inch tire cannot mount on a 19-inch wheel, and the reverse is equally true. It also helps to confirm wheel width before final tire selection, especially on cars that may have had aftermarket wheels installed at some point.

The 2013 Audi A5 Cabriolet follows the same fitment pattern and uses the same two radial tire sizes: 245/40R18 and 255/35R19. The deciding factor is still the wheel diameter on the individual car, not the Cabriolet name by itself.

That means Cabriolet owners should verify whether the car is currently set up with 18-inch or 19-inch wheels before selecting tires. Once the wheel size is confirmed, the choice shifts to comparing available radial products, sidewall styles, and tire series in the correct fitment.

Start with the correct size and wheel compatibility. For a 2013 Audi A5 on 18-inch wheels, 245/40R18 keeps the fitment in the proper rim diameter while giving access to several radial choices, including performance-oriented blackwalls and select redline or raised white letter options.

After size is settled, compare the tire series, intended use, and wheel-width suitability. A buyer focused on modern street performance may look at BFGoodrich or Nitto offerings, while someone who wants a more distinctive visual treatment may prefer the Pro-Trac Street Pro III sidewall options in the same size.

Sidewall style depends on tire size. In 245/40R18, available choices include blackwall, redline, and RWL, while 255/35R19 options are centered on blackwall designs. All of these remain radial tires, but the sidewall treatment changes the visual character of the car.

That matters most if appearance is part of the decision rather than pure fitment. A blackwall keeps a more modern understated look, while redline or raised white letter styling creates a more customized presentation. Matching the sidewall style to the car’s wheel design and overall theme usually leads to the most satisfying result.

Tires for the 2013 Audi A5 are available from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, depending on size. The broader mix appears in 245/40R18, while 255/35R19 choices are concentrated in BFGoodrich g-Force series applications.

Brand selection should still come after confirming the correct wheel diameter and tire size. Once that is done, compare each option by tire series, sidewall style, rim-width compatibility, and how the car will be used, whether that means regular road driving, a more aggressive street setup, or a specialized drag-oriented application.

A period-style 2013 Audi A5 tire choice starts with keeping the correct modern radial size for the wheel diameter already on the car: 245/40R18 or 255/35R19. From there, the visual direction depends on whether the goal is a contemporary factory-inspired look or a more customized presentation.

Blackwall tires usually maintain the cleanest original-era appearance for a car of this vintage, especially on 19-inch fitments. In 18-inch applications, redline and RWL options offer a more personalized look, but buyers focused on authenticity should compare those styling choices against period brochures, dealer literature, or marque-specific references.

Construction is simple on the 2013 Audi A5 because the primary fitments are radial. That keeps the visual effect centered less on bias-ply versus radial differences and more on profile, wheel diameter, and sidewall treatment within the correct modern radial size.

For a restoration-oriented or carefully preserved car, the biggest appearance decisions are whether to stay with an understated blackwall look or choose a more expressive sidewall in 18-inch fitment. Preserving the correct low-profile proportions is especially important, since the tire’s profile has a strong effect on how the A5 sits and presents.

Yes. A 2013 Audi A5 may share the same basic tire sizes across the model range, but aftermarket wheels, suspension changes, lowered ride height, or body modifications can all affect whether the intended tire setup remains appropriate on the car.

Even when the tire size is correct on paper, wheel width, offset, and available clearance still matter. A careful check of steering travel, fender clearance, and suspension condition is worthwhile before fitting new tires, especially if the car no longer sits on its original wheel and suspension configuration.

Before road use, inspect tire pressure, tread condition, valve stems, wheel condition, and any signs of rubbing or uneven wear. It also helps to confirm that all four tires match the intended size for the wheel setup and that there are no cuts, bulges, or visible mounting issues.

A quick check of alignment-related wear patterns and suspension condition is also smart on a performance-oriented car like the A5. Fresh tires perform best when the wheels are true, the suspension is healthy, and the vehicle is set up to carry the tire evenly across the contact patch.

Tires on a 2013 Audi A5 should be checked regularly, not just when tread looks low. Monthly pressure checks are a sensible baseline, and visual inspections should happen before longer drives or any time the car has been sitting for an extended period.

Regular inspection helps catch uneven wear, damage, or slow air loss before those issues affect ride quality or handling. On a car with low-profile tires, it is also wise to watch for sidewall damage from potholes or curb contact, since shorter sidewalls leave less margin for impact-related problems.
